I-SSA: Interaction-Situated Semantic Alignment

SSP Seminar Series
Manuel Atencia, IIIA-CSIC, Barcelona, Spain

In this talk we will present Interaction-Situated Semantic Alignment (or I-SSA), a novel approach to tackle semantic heterogeneity in multi-agent communication. I-SSA looks at semantics related to interaction in order to avoid dependency on a priori semantic agreements. We do not assume existence of any ontologies, neither local to interacting agents nor external to them, and we rely only on interactions themselves to resolve terminological mismatches. Our underlying claim is that semantic alignment is often relative to the particular interaction in which agents are engaged, and, that in such cases the interaction state should be taken into account and brought into the alignment mechanism. We will show a formal foundation of I-SSA by means of a mathematical object inspired from category theory called the communication product, along with an alignment mechanism based on it. In addition, we will describe an alignment protocol that agents can follow so as to benefit from this approach in practice.
