Abstract
The present article will introduce a proposition of semiotic methodology that can be used to diagnose cohabitation issues in cities between human inhabitants and non-human liminals. This methodology is built on a few sets of data that should be easy to obtain in any important city, and can therefore be utilised in a variety of situations. The different sets of data allow us to map the cohabitation semiosphere (following Hoffmeyer’s meaning of the term) of the situation along three axes: the materiality of the situation, the symbolic significance of the relationship, and the emotional significance of the interaction. These three aspects allow us to see gaps, paradoxes and points of consistency, enabling complex and multi-level understanding of the situation.
