Description

Agents can adapt their knowledge using different adaptation operators and modalities. These may be considered as knowledge, so they also may be adapted and selected.

Cultural evolution is the application of evolution theory to culture [Messoudi 2006]. It may be addressed through multi-agent simulations [Steels 2012]. Experimental cultural evolution provides a population of agents with interaction games that are played randomly. In reaction to the outcome of such games, agents adapt their knowledge. It is possible to test hypotheses by precisely crafting the rules used by agents in games and observing the consequences.

Our ambition is to understand and develop general mechanisms by which a society evolves its knowledge. For that purpose, we adapted this approach to the evolution of the way agents represent knowledge [Euzenat, 2014, 2017; Anslow & Rovatsos, 2015; Chocron & Schorlemmer, 2016]. We showed that cultural repair is able to converge towards successful communication and improves the objective correctness of alignments.

In the recent years, we developed different types of agents with various adaptation operators and modalities [Euzenat 2017]. These are used by agents to select knowledge. However, as such they can also be considered knowledge, hence selected.

The goal of this research topic is to consider agents able to use any of these operators and modalities Then experiments may be designed so that agents not only select target knowledge, but as well select the operators for selecting knowledge among a library of available methods.

They may do this judging by various criterion: speed, success, coverage. We want to study the impact of this process on similar long term criterion applied to target knowledge.

Another alternative, is to have experiments using such agents and having the environment selecting those with the fittest choices.

This work is part of an ambitious program towards what we call cultural knowledge evolution. It is part of the MIAI Knowledge communication and evolution chair and as such may lead to a PhD thesis.
