The paper describes four dialogue systems, developed in the tradition of Charles Hamblin. The first system provides an answer for Achilles in Lewis Carroll's parable, the second an analysis of the fallacy of begging the question, the third a non-psychologistic account of conversational implicature, and the fourth an analysis of equivocation and of objections to it. Each avoids combinatorial explosions, and is intended for real-time operation.

This paper builds a dialectical system of explanation with speech act rules that define the kinds of moves allowed, like requesting and offering an explanation. Pre and post-condition rules for the speech acts determine when a particular speech act can be put forward as a move in the dialogue, and what type of move or moves must follow it. A successful explanation has been achieved when there has been a transfer of understanding from the party giving the explanation to (...) the party asking for it. The dialogue has an opening stage, an explanation stage and a closing stage. Whether a transfer of understanding has taken place is tested by a dialectical shift to an examination dialogue. (shrink)

This paper shows how a dialogue system for information-seekingdialogues can be implemented in a type-theory-based syntax editor,originally developed for editing mathematical proofs.The implementation gives a simple logical metatheory tosuch dialogue systems and also suggests new functions forthem, e.g., a local undo operation. The method developed provides alogically based declarative way of implementing simple dialoguesystems that is easy to port to new domains.

Dialogue systems, from Virtual Personal Assistants such as Siri, Cortana, and Alexa to state-of-the-art systems such as BlenderBot3 and ChatGPT, are already widely available, used in a variety of applications, and are increasingly part of many people’s lives. However, the task of enabling them to use empathetic language more convincingly is still an emerging research topic. Such systems generally make use of complex neural networks to learn the patterns of typical human language use, and the interactions (...) in which the systems participate are usually mediated either via interactive text-based or speech-based interfaces. In human–human interaction, empathy has been shown to promote prosocial behaviour and improve interaction. In the context of dialogue systems, to advance the understanding of how perceptions of empathy affect interactions, it is necessary to bring greater clarity to how empathy is measured and assessed. Assessing the way dialogue systems create perceptions of empathy brings together a range of technological, psychological, and ethical considerations that merit greater scrutiny than they have received so far. However, there is currently no widely accepted evaluation method for determining the degree of empathy that any given system possesses (or, at least, appears to possess). Currently, different research teams use a variety of automated metrics, alongside different forms of subjective human assessment such as questionnaires, self-assessment measures and narrative engagement scales. This diversity of evaluation practice means that, given two DSs, it is usually impossible to determine which of them conveys the greater degree of empathy in its dialogic exchanges with human users. Acknowledging this problem, the present article provides an overview of how empathy is measured in human–human interactions and considers some of the ways it is currently measured in human–DS interactions. Finally, it introduces a novel third-person analytical framework, called the Empathy Scale for Human–Computer Communication (ESHCC), to support greater uniformity in how perceived empathy is measured during interactions with state-of-the-art DSs.

Formal dialogue systems model rule-based interaction between agents and as such have multiple applications in multi-agent systems and AI more generally. Their conceptual roots are in formal theories of natural argumentation, of which Hamblin’s formal systems of argumentation in Hamblin (Fallacies. Methuen, London, 1970, Theoria 37:130–135, 1971) are some of the earliest examples. Hamblin cites the medieval theory of obligationes as inspiration for his development of formal argumentation. In an obligatio, two agents, the Opponent and the (...) Respondent, engage in an alternating-move dialogue, where the Respondent’s actions are governed by certain rules, and the goal of the dialogue is establishing the consistency of a proposition. We implement obligationes in the formal dialogue system framework of Prakken (Knowl Eng Rev 21(2):163–188, 2006) using Dynamic Epistemic Logic (van Ditmarsch et al. in Dynamic epistemic logic, Synthese Library Series. Springer, Berlin, 2007). The result is a new type of inter-agent dialogue, for consistency-checking, and analyzing obligationes in this way also sheds light on interpretational and historical questions concerning their use and purpose in medieval academia.

In this paper, it is shown how formal dialectic can be extended to model multi-agent argumentation in which each participant is an agent. An agent is viewed as a participant in a dialogue who not only has goals, and the capability for actions, but who also has stable characteristics of types that can be relevant to an assessment of some of her arguments used in that dialogue. When agents engage in argumentation in dialogues, each agent has a credibility (...) function that can be adjusted upwards or downwards by certain types of arguments brought forward by the other agent in the dialogue. One type is the argument against the person or argumentum ad hominem, in which personal attack on one party's character is used to attack his argument. Another is the appeal to expert opinion, traditionally associated with the informal fallacy called the argumentum ad verecundiam. In any particular case, an agent will begin a dialogue with a given degree of credibility, and what is here called the credibility function will affect the plausibility of the arguments put forward by that agent. In this paper, an agent is shown to have specific character traits that are vital to properly judging how this credibility function should affect the plausibility of her arguments, including veracity, prudence, sincerity and openness to opposed arguments. When one of these traits is a relevant basis for an adjustment in a credibility function, there is a shift to a subdialogue in which the argumentation in the case is re-evaluated. In such a case, it is shown how the outcome can legitimately be a reduction in the credibility rating of the arguer who was attacked. Then it is shown how the credibility function should be brought into an argument evaluation in the case, yielding the outcome that the argument is assigned a lower plausibility value. (shrink)

In his book on fallacies, Hamblin built a very simple system for argumentation in dialogue he called the Why Because System with Questions. In his discussion of this system, he replaced the concept of burden of proof with a simpler concept of initiative, which could be described as something like getting the upper hand as the argumentation moves back and forth in the dialogue between the one party and the other. No doubt he realized that the concept of (...) burden of proof was too complex a matter to be dealt with in the limited scope of his chapter on formal dialogue systems. In this paper is shown how an extended version of Hamblin’s dialogue system provides a nice way of modeling the phenomenon of shifting of burden of proof in a dialogue, yielding a precise way of distinguishing between different kinds of burden of proof, and dealing with fallacies like the argumentum ad ignorantiam.

Formal dialogue games have been studied in philosophy since at least the time of Aristotle. Recently they have been applied in various contexts in computer science and artificial intelligence, particularly as the basis for interaction between autonomous software agents. We review these applications and discuss the many open research questions and challenges at this exciting interface between philosophy and computer science.

The dialogue develops arguments for and against a broad new world system - info-computationalist naturalism - that is supposed to overcome the traditional mechanistic view. It would make the older mechanistic view into a special case of the new general info-computationalist framework (rather like Euclidian geometry remains valid inside a broader notion of geometry). We primarily discuss what the info-computational paradigm would mean, especially its pancomputationalist component. This includes the requirements for a the new generalized notion of computing that (...) would include sub-symbolic information processing. We investigate whether pancomputationalism can provide the basic causal structure to the world and whether the overall research program of info-computationalist naturalism appears productive, especially when it comes to new approaches to the living world, including computationalism in the philosophy of mind.

Section 1 contains a survey of options in constructing a formal system of dialogue rules. The distinction between material and formal systems is discussed (section 1.1). It is stressed that the material systems are, in several senses, formal as well. In section 1.2 variants as to language form (choices of logical constants and logical rules) are pointed out. Section 1.3 is concerned with options as to initial positions and the permissibility of attacks on elementary statements. The problem (...) of ending a dialogue, and of infinite dialogues, is treated in section 1.4. Other options, e.g., as to the number of attacks allowed with respect to each statement, are listed in section 1.5. Section 1.6 explains the concept of a chain of arguments.From section 2 onward four types of dialectic systems are picked out for closer study: D, E, Di and Ei. After a preliminary section on dialogue sequents and winning strategies, the equivalence of derivability in intuitionistic logic and the existence of a winning strategy (for the Proponent) on the strength of Ei is shown by simple inductive proofs.

This paper summarizes Ervin Laszlo’s worldview in The Systems View of the World: A Holistic Vision for Our Time.1 Laszlo claims that current discoveries in the sciences have led to a different model of the physical world, human nature, and human culture. Instead of the models formulated during the Enlightenment, according Systems thinkers “systems interact with systems and collaboratively form suprasystems”. This view has led to a reexamination of: 1) each academic discipline; 2) the relationship between (...) disciplines; 3) the nature of theory and its relation to practice; 4) the relationship between religion and the sciences; 5) of the nature of the social sciences and our ability to develop a universal, normative ethic; 6) the relation between reasoning, emotion and imagination. The evolution of the reflective self-consciousness unique to homo sapiens has led to the formation of cultures. Cultures must be understood assuprasystems that emerged from natural systems and are dependent upon them. Given this universal natural foundation, systems thinkers are recognizing the common patterns between nature and culture and between different cultures. The examination of systems has also shown us that the suprasystems of culture create a level of complexity and reality over and above the natural world and can even destroy themselves and their own natural foundationFrom the perspective of the ISUD, this view means it is possible, natural, and necessary for academics to engage in meaningful dialogue with each other, showing how the ways they have been trained to examine “reality,” or “truth,” can be integrated. Further, professional academics should be able to talk to non-academics, to people in leadership roles, and to all human actors. Since it is a fact that individuals are parts of many larger wholes, the ISUD can nurture the process of the development of reflective self-consciousness in the formation of an international culture, an emerging suprasystem.Laszlo calls this sphere of spiritual interaction, with its physical foundation, a noosphere, his word for a “meeting of the minds.” Given our collective destruction of natural systems, it is imperative that human beings develop some version of a Systems view of reality. ISUD should work to foster this development, even though the professional training of individuals will call the process by other names, based on the labels of the past. (shrink)

This thesis seeks to extend the search for the moral implications inherent in the development, possession and threatened use of physical/astrophysical processes and in current understandings of the evolution of the physical universe. ;The nature of moral/theological discussion will not be a primary concern although clearly some residual position that such discussion is meaningful is presupposed. Neither is the nature of science or the scientific method at issue. It is assumed that both theology and science have long since negotiated the (...) confidence crises of adolescence and have mustered the requisite self-esteem regarding their respective disciplines. ;The aim of this work is to present the concept of time-scales as a relevant moral category. It will investigate the use of this concept and its relationship to the other categories developed in the relevant scientific literature. Similarly, the use of this concept will be explored and its influence sought in the analogous documentation from the Catholic tradition. In this investigation the question will be raised as to the validity of and the future of the concept of time-scales as a common moral ground for these two traditions, enhancing convergence and leading toward a more direct collaboration on the question of human survival.

Any approach to the study of managerial situations undertaken without reflection on the underpinning philosophy is flawed because it limits our ability to question the validity of the knowledge claimed in the analysis. The paper considers this issue and presents a philosophical reflection on the use of a systems approach to the modelling of human enterprises. It draws on insights from systems thinking, cognitive science, autopoiesis, communication theory and non-linear dynamics. These are interpreted within the context of social (...) systems as networks of conversations that are generated in language. It is written to invite an exchange of ideas concerning the role of the generative dialogue. (shrink)

The book begins with the problem of the relationship between systematic philosophy and the history of philosophy. Why does philosophy attach so much importance to history? Consideration of this question is an essential part of metaphysics, and it has important consequences for the methodology of both history and philosophy. An analysis of the problem that begins the book leads to many other fundamental questions concerning the nature of philosophy. In treating these issues the author discusses positions taken on them by (...) Russell, Rorty, Heidegger, Gadamer, Levinas, Ricoeur, Derrida, and others of our century. He also draws inspiration from Plato, Plotinus, Augustine, Spinoza, Kant, Hegel, and Nietzsche. (shrink)

A thought is a mental state with a phenomenal aspect; it is essentially subjective. However, in Yorùbá thought system, a thought involves third persons or objective perspectival aspects. This is contrary to the nature of thoughts, hence the need to explain how the distinct properties of subjectivity and objectivity are found in Yorùbá thoughts system. The paper is divided into three parts. The first explores the nature of phenomenality in human mental states. The second explains that the Yorùbá thoughts system (...) is linked with the embodied cognitive system. It is argued that when an average Yorùbá thinks, such a thought is a dialogue between the first person and third persons or objects. The third part draws examples from Yorùbá thought system to illustrate the complementariness between the first-person character and the objective or external elements of mental state. (shrink)

The first part of the present study provides a short historical illustration of the genuine character of philosophy as (...) a bearer of reform, while the second part of the work mentions different attitudes toward reform, as well as the problems generated by the intersection of these attitudes with the reforms promoted by philosophy. In addition, the paper intends to contribute to the understanding of the present-day status of philosophy within the Romanian educational system. In this respect, the dialogue of philosophy and religion is considered relevant to the topic. Besides this aspect, the work also mentions the dogmatic imprint of philosophy during the Stalinist epoch and the dogmatic inertia after 1990 – manifested in different and apparently opposed forms. Moreover, the study suggests that the improvement of the prestige of philosophy depends not only upon the self-criticism that Romanian philosophy has to develop but also upon the influence that this spirit of self-criticism could have on decision-makers. Philosophical self-criticism is a precondition and, at the same time, a part of the reform that philosophy initiates in the field of knowledge. Thus, the paper is to underline the importance of philosophy in giving direction and in providing the framework for social reform. From this point of view, the dialogue between philosophy and religion is difficult but possible at university level and in the field of research. (shrink)

Culture as a dynamic system of meaningful relations can naturally accommodate a hermeneutic analysis. In this essay, the notion of Gadamer’s hermeneutics as involving interpretable meaning throughout experiential reality permits a natural concordance with an understanding of culture as meaningful. The Gadamerian idea that prejudices inform the horizons that make our experiences intelligible is applied to the view that culture is both a self-enclosed structure that is given by one’s horizon and one that continuously points past this horizon in genuine (...) dialogue. Nevertheless, in seeing culture as a coherent system that transcends itself, we are consequently faced with a dilemma regarding the evolution of one’s cultural horizons: whether past horizons can survive the creation of novel ones through dialogue. However, this may be resolved through Gadamer’s understanding of the functions of sameness and difference within horizonal evolution, and how these functions feature in the distinction between a shared ontological ground and the horizons through which the ground is interpreted. Ultimately, we showcase how it is noncontradictory to suppose that culture is both self- and other-referential. (shrink)

This paper presents a dialogue system called Lorenzen–Hamblin Natural Dialogue (LHND), in which participants can commit formal fallacies and have a method of both identifying and withdrawing formal fallacies. It therefore provides a tool for the dialectical evaluation of force of argument when players advance reasons which are deductively incorrect. The system is inspired by Hamblin’s formal dialectic and Lorenzen’s dialogical logic. It offers uniform protocols for Hamblin’s and Lorenzen’s dialogues and adds a protocol for embedding them. This (...) unification required a reformulation of the original description of Lorenzen’s system to distinguish “between different stances that a person might take in the discussion”, as suggested by Hodges. The LHND system is compared to Walton and Krabbe’s Complex Persuasion Dialogue using an example of a dialogue. (shrink)

For all the differences in the teachings and fate of Franz Rosenzweig and Mikhail Bakhtin, comparing them with one another is extremely instructive and reveals important and often lost meanings of 20th-century philosophy. Bakhtin made his debut in 1929 as the author of Problems of Dostoevsky’s Creative Art, but then went into exile for sufficient years and emerged from oblivion only in the 1960s. Rosenzweig died in 1929 and was almost forgotten for many years. Now, almost a century later, we (...) see in Bakhtin’s philosophy, especially in his early works, and in Rosenzweig’s philosophy very much in common. Both sought to create a new philosophical system that radically rethinks the subject of philosophy. Both went beyond the traditional New European ontology, both recognized the fundamentality of language and language arts in the philosophy of the future, and, finally, both became the creators of the philosophy of dialogue as an important trend in 20th-century thought. For all that, there were many cultural, religious, and intellectual differences between Bakhtin and Rosenzweig. However, consideration of both the commonalities and differences in their philosophical systems is extremely fruitful not only for the cultural history of the 20th century but also for philosophical studies of the future.

For all Habermas's remarkable contribution to moral theory, his discourse ethics has left behind some debatable points. In particular, `delinguistified media' such as money and power have been excluded from the domain of moral discourse. The exclusion of money and power from the domain of moral discourse has also motivated Habermas to develop an idea of `colonization of lifeworld by system' by giving us the impression that the delinguistified media are the main culprit of colonizing the lifeworld. In this article, (...) by drawing on Reinhold Niebuhr's theological ethics, I argue that the lifeworld is colonized not by the delinguistified media as such, but, rather, by the people who mismanage money and power. I also develop the argument that in order to `decolonize' the colonized lifeworld, we need the substantive ethical ideals as well as the communicatively established law to guide the moral conduct of these system managers.

ABSTRACT:Must even Confucian rights skeptics—those who are, on account of their Confucian beliefs, skeptical of the existence of human rights, and believe that asserting or recognizing rights is morally wrong—concede that in the workplace, they are morally obligated to recognize rights? Alan Strudler has recently argued that such is the case. In this article, I argue that because Confucian rights skeptics locate wrongness in inconsistency with the idea of “Confucian community,” Confucian community should be viewed as a moral ideal. I (...) then argue that Confucian rights skeptics ought to act in a manner that is consistent with this ideal, even when the ideal has not yet been realized, just as Kantians ought to act consistently with the Kantian kingdom of ends ideal. Accordingly, contrary to Strudler, I argue that Confucian rights skeptics need not concede that they are morally obligated to recognize rights in the workplace. This conclusion suggests the need for inquiry into the metaphysical foundations of these conflicting views. However, such inquiry is commonly thought to lie beyond the scope of philosophical business ethics proper. I conclude the article by suggesting a number of reasons for business ethicists to consider rejecting the prevalent narrow conception of the scope of the discipline.In this discussion I explore challenges to a particular Confucian system of morality that generally eschews reliance on rights. I argue that such a system may at the same time both assert that there are moral problems with rights and assert that it is acceptable to invoke rights in limited contexts. Adam Bailey has objected that the position I defend is inconsistent. I answer Bailey’s objections. (shrink)

With the widespread infusion of online technology there has been an increase in various studies investigating the practices in online communities including also philosophical perspectives. What those debates have in common is that they call for more critical thinking about the theory of online communication. Drawing on Techno-Anthropological research perspectives, our interest is placed on exploring and identifying human interactions and technology in intersectional spaces. This article explores information systems that allow for interchanges of different users. We discuss ontological (...) assumptions that focus on understanding the kind of dialogue that can be captured between different expert groups when they utilize information systems. We present the notion of ‘dialogic’ by Mikhail Bakhtin and contextualize it through an analysis of online dialogue. Dialogic or ‘conversation and inquiry’ is discussed as being mediated through human relationships. Acknowledging the existence of at least two voices the underlying differences between dialogue partners are highlighted. (shrink)

This paper offers a new model of belief by embedding the Peircean account of belief into a formal dialogue system that uses argumentation schemes for practical reasoning and abductive reasoning. A belief is characterised as a stable proposition that is derived abductively by one agent in a dialogue from the commitment set (including commitments derived from actions and goals) of another agent. On the model (to give a rough summary), a belief is defined as a proposition held by (...) an agent that (1) is not easily changed (stable), (2) is a matter of degree (held more or less weakly or strongly), (3) guides the goals and actions of the agent, and (4) is habitually or tenaciously held in a manner that indicates a strong commitment to defend it. It is argued that the new model overcomes the pervasive conflict in artificial intelligence between the belief-desire-intention model of reasoning and the commitment model. (shrink)

Dialogue has its origins in joint activities, which it serves to coordinate. Joint activities, in turn, usually emerge in hierarchically nested projects and subprojects. We propose that participants use dialogue to coordinate two kinds of transitions in these joint projects: vertical transitions, or entering and exiting joint projects; and horizontal transitions, or continuing within joint projects. The participants help signal these transitions with project markers, words such as uh-huh, m-hm, yeah, okay, or all right. These words have been (...) studied mainly as signals of listener feedback (back-channel signals) or turn-taking devices (acknowledgment tokens). We present evidence from several types of well-defined tasks that they are also part of a system of contrasts specialized for navigating joint projects. Uh-huh, m-hm and yeah are used for horizontal transitions, and okay and all right for vertical transitions. (shrink)

Being a pragmatic and not a referential approach to semantics, dialogi-cal logic does not understand semantics as mapping names, propositions and relationships into the real world to obtain an abstract counterpart of it, but as dealing (handeln) with them in a particular way. This allows a very simple formulation of free logic the core of which can be expressed in a nutshell, namely: in an argumentation, it sometimes makes sense to restrict the introduction of singular terms in the context of (...) quantification to a formal use o f them. That is, the proponent is allowed to use a constant if f this constant has been explicitly conceded by the opponent.

This paper aims to develop the implications of logical expressivism for a theory of dialogue coherence. I proceed in three steps. Firstly, certain structural properties of cooperative dialogue are identified. Secondly, I describe a variant of the multi-agent natural deduction calculus that I introduced in Piwek (J Logic Lang Inf 16(4):403–421, 2007 ) and demonstrate how it accounts for the aforementioned structures. Thirdly, I examine how the aforementioned system can be used to formalise an expressivist account of logical (...) vocabulary that is inspired by Brandom (Making it explicit: reasoning, representing, and discursive commitment, 1994 ; Articulating reasons: an introduction to inferentialism, 2000 ). This account conceives of the logical vocabulary as a tool which allows speakers to describe the inferential practices which underlie their language use, i.e., it allows them to make those practices explicit. The rewards of this exercise are twofold: (1) We obtain a more precise account of logical expressivism which can be defended more effectively against the critique that such accounts lead to cultural relativism. (2) The formalised distinction between engaging in a practice and expressing it, opens the way for a revision of the theory of dialogue coherence. This revision eliminates the need for logically complex formulae to account for certain structural properties of cooperative dialogue. (shrink)

This book focuses on dialog from a varied combination of fields: Linguistics, Philosophy of Language and Computation. It builds on the hypothesis that meaning in human communication arises at the discourse level rather than at the word level. The book offers a complex analytical framework and integration of the central areas of research around human communication. The content revolves around meaning but it also gives evidence of the connection among different points of view. Besides discussing issues of general interest to (...) the field, the book triggers theoretical argumentation that is currently under scientific discussion. It examines such topics as immanent reasoning joined with Recanati's lekta and free enrichment, challenges of internet conversation, inner dialogs, cognition and language, and the relation between assertion and denial. It proposes a dialogical framework for intra-negotiation and gives a geolinguistic perspective on spoken discourse. Finally, it examines dialog and abduction and sheds light on a generation of dialog contexts by means of multimodal logic applied to speech acts. (shrink)

It has been remarked, my Hermippus, that though the ancient philosophers conveyed most of their instruction in the form of dialogue, this method of composition has been little practised in later ages, and has seldom succeeded in the hands of those who have attempted it. Accurate and regular argument, indeed, such as is now expected of philosophical enquirers, naturally throws a man into the methodical and didactic manner; where he can immediately, without preparation, explain the point at which he (...) aims; and thence proceed, without interruption, to deduce the proofs on which it is established. To deliver a SYSTEM in conversation, scarcely appears natural; and while the dialogue-writer desires, by departing from the direct style of composition, to give a freer air to his performance, and avoid the appearance of Author and Reader, he is apt to run into a worse inconvenience, and convey the image of Pedagogue and Pupil. Or, if he carries on the dispute in the natural spirit of good company, by throwing in a variety of topics, and preserving a proper balance among the speakers, he often loses so much time in preparations and transitions, that the reader will scarcely think himself compensated, by all the graces of dialogue, for the order, brevity, and precision, which are sacrificed to them.

PurposeThe purpose of this paper is to explore a particular philosophical underpinning for Information Systems (IS) research – critical systemic thinking (CST). Drawing upon previous work, the authors highlight the principal features of CST within the tradition of critical research and attempt to relate it to trends in the Italian school of IS research in recent years, as exemplified by the work of Claudio Ciborra but also evident in work by, e.g. Resca, Jacucci and D'Atri.Design/methodology/approachThis is a conceptual paper (...) which explores CST, characterised by a focus on individual uniqueness, and socially‐constructed, individual worldviews as generators of human knowing.FindingsThe paper draws on work by Heinz Klein in which he elaborated three constitutive stages in critical research: interpretive, genealogical and constructive. The authors introduce a fourth, reflective stage and discuss five categories of critical research, reflecting different perspectives on emancipation, culminating in emergent expressionism, associated with Ciborra and the Italian school more generally.Research limitations/implicationsThis paper discusses approaches to CST and how they might have practical implications in IS development. The distinction between approaches founded in logical empiricism and those founded in hermeneutic dialectics are considered and the development of critical and systems strands are discussed.Practical implicationsThe paper addresses CST as an approach to development of information systems. Such approaches enable users to explore their individually unique understandings and create a constructive dialogue with one another, which emancipates and empowers users to own and control their own development processes and hence build more productive and usable systems.Social implicationsA focus on research which is oriented towards emancipation in the tradition of critical social theory.Originality/valueThe paper draws on extensive theoretical research carried out by the authors over a period of more than ten years in CST and synthesises the practical implications.

When people engage in conversation, they tailor their utterances to their conversational partners, whether these partners are other humans or computational systems. This tailoring, or adaptation to the partner takes place in all facets of human language use, and is based on a mental model or a user model of the conversational partner. Such adaptation has been shown to improve listeners' comprehension, their satisfaction with an interactive system, the efficiency with which they execute conversational tasks, and the likelihood of (...) achieving higher level goals such as changing the listener's beliefs and attitudes. We focus on one aspect of adaptation, namely the tailoring of the content of dialogue system utterances for the higher level processes of persuasion, argumentation and advice-giving. Our hypothesis is that algorithms that adapt content for these processes, according to a user model, will improve the usability, efficiency, and effectiveness of dialogue systems. We describe a multimodal dialogue system and algorithms for adaptive content selection based on multi-attribute decision theory. We demonstrate experimentally the improved efficacy of system responses through the use of user models to both tailor the content of system utterances and to manipulate their conciseness. (shrink)

Purpose. Institutionalism is gaining strength as a dominant point of view on the world. Its philosophical basis is the postulate of the uncertainty of the development, which comes to replace the neoclassical certainty characteristic of industrial society. The postulate of uncertainty is closely connected with the idea of subjectivization and individualization of post-industrial society. All these were very important components of the new paradigm, although they do not exhaust the problem. In the heart of postmodernism is a mass identity as (...) a spiritual substance, while the more recently mass of people to realize themselves as natural and social beings. Person has absolute freedom in the acceptance and rejection of culture and civilization; it is pluralistic in their actions and in their consciousness. It is the subject of history and it should be creative, fluent mastering all the achievements of culture. Methodology. The dialogue system of the Postmodern, which is the basis of human communication with another person, human with society is a model of convergent formation of the world community and world economy. The same model of rationalism and adequate industrial society is a monologue, which is easily builds a bridge to violence, even if it is carried out in the name of the man behind him and the pathos of the exaltation of man as the bearer of unlimited creation possibilities. However, it is very important not just to modify rationalism, and to understand the origins of civilization. Scientific novelty. The postmodern era begins is not easy. Modern defending, using all their reserves: public thirst for justice, the priority of rationality, monologist public agencies and politicians in contrast to the dialogic postmodern imperative modality in the spiritual existence of man instead the freedom. Finally, the world of the story is set a trap – the anthropological paradigm of the globalization ideology formation. In this paradigm, people see materialistic rational measure of space and society building, i.e. the natural and social being, not a spiritual person. All this was evident in the course of transformation in Ukraine. Its main weakness is obvious. This narrows the field of mass participation in the market or by the adopted symbolism, the field of subjectivity. The population is invited to wait and endure, i.e. plays the role of the object of political and economic manipulation. Even more unacceptable monopolization of subjectivity government, for which everything is regarded as a subject of state regulation. Conclusions. For civilization of cardinal feature is the treatment of the person as the subject of history. The need for the development of civilization to increase the degree of subjectivity in an economy where people can express themselves freely and responsibly through a system of private property relations: economic entity is the subject of property. Policy enhancing the role of human rights and the development of the principle of subjectivity means deepening the democratic foundations of the state structure. In the social sphere the subjectivity is expressed in the individualization of the social existence of man and the personification of public relations and it is implemented through the mechanisms of liberal institutions. It seems that the civilizational unity of the economy, democratic state and liberal society has the value of a scientific paradigm. Whatever the great cultural peaks of the postmodern, the main processes of a new society formed at its foot: in the area of formation of public consciousness and public preferences with the mass participation of the individual in the economy, in the field of state-building and the formation of social institutions on the principles of Amateur participation.

ABSTRACT:This commentary develops my position on the ethics of price gouging in response to Jeremy Snyder's article, “What's the Matter with Price Gouging.” First, it explains how the “nonworseness claim” supports the moral permissibility of price gouging, even if it does not show that price gougers are morally virtuous agents. Second, it argues that questions about price gouging and distributive justice must be answered in light of the relevant possible institutional alternatives, and that Snyder's proposed alternatives to price gouging fare (...) worse on the dimension of justice than a system in which goods are allocated by a system of market prices.

There are several formal systems for persuasive dialogue. Dialogue systems are multi-Agent systems, and this contrasts with the general lack of any agency in standard logics other than in the case of epistemic and deontic logics. Dialogue systems have been called logics. A logic usually has a semantics and a proof system, and questions of soundness and completeness arise. Any dialogue conducted according to the rules of a dialogue logic is a (...) complex process. Dynamic Logic is a logic of processes, with a possible world semantics. This paper is a preliminary exploration of transforming the dialogues of dialogue logic into complex Dynamic Logic processes with emphasis on semantic models. The transformation gives rise to many questions, three of which are discussed. Dialogue logic includes commitment sets which behave in a way similar to belief sets and undergo changes during any dialogue. There are issues as to the relationship between belief and commitment, and whether the logics of belief change apply to commitment stores. There is also the issue of the logical nature of the evaluation of dialogues as legal or illegal. (shrink)

Current formal dialectical models postulate normative rules that enable discussants to conduct dialogical interactions without committing fallacies. Though the rules for conducting a dialogue are supposed to apply to interactions between actual arguers, they are without exception theoretically motivated. This creates a gap between model and reality, because dialogue participants typically leave important content-related elements implicit. Therefore, analysts cannot readily relate normative rules to actual debates in ways that will be empirically confirmable. This paper details a new, data-driven (...) method for describing discussants’ actual reply structures, wherein corpus studies serve to acknowledge the complexity of natural argumentation. Rather than refer exclusively to propositional content as an indicator of arguing pro/contra a given claim, the proposed approach to dialogue structure tracks the sequence of dialogical moves itself. This arguably improves the applicability of theoretical dialectical models to empirical data, and thus advances the study of dialogue systems. (shrink)
