MOSIG Master 2ND
Evolution theory may be applied to knowledge which is variable, communicated and selected among populations. Generalised theories of evolution introduce the notion of replicators (generalising genes) which generate an interactor (generalising phenotype) which is subject to natural selection. Because knowledge is the cause of individual behaviour which is subject to selection, either by the individual or its environments, it is tempting to apply this model to knowledge evolution.
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.
This has been applied to the evolution of the way agents represent knowledge [Euzenat 2014; Anslow 2015; Chocron 2016]. We have applied it to ontology alignment repair, i.e., the improvement of incorrect alignments [Euzenat 2014; 2017a]. We showed that cultural repair is able to converge towards successful communication and improves the objective correctness of alignments.
Modern theories of evolution may be based on the concept of replicator/interactor which generalises that of genotype/phenotype [Dawkins 1976; Hull 1980; Wilkins 2014]. Like genes, replicators may be transmitted to the offspring almost perfectly, modulo mutation (variation). They are also the pattern for the whole organism: they determine the traits (phenotype) of individuals. Among those traits expressed by genes, some are under the pressure of the environment (interactors). Hence, depending on these traits, organisms will be more or less fit to the environment (in good shape to eat, survive, mate, have offspring). Thus selection operates indirectly on the capacity of replicators to been inherited.
The replicator/interactor model seems to fit perfectly knowledge evolution. Indeed, we transmit our knowledge (replicator) and it influences our behaviour (interactor). In turns, this behaviour is what will be selected by the environment, by others and ultimately by ourselves. The figure below explain how agents may be built following this model.
There are however differences between the genuine generalisation of genetics and cultural knowledge evolution:
The goal of this master topic is to apply explicitly the replicator/interactor model to knowledge evolution. This involves further designing agents implementing this model and experiments that highlight the properties of such agents, in particular, with respect to some of the differences noted above.
Expected contributions are firstly the design of agents applying the replictor/interactor model to knowledge as well as the study of the behaviour of such agents, e.g., their capability to evolve knowledge.
This work is part of an ambitious program towards what we call cultural knowledge evolution and may prepare to a PhD.
