Abstract
Agreement on word-object pairing in communication depends on the intensity
of belief that gradually emerges in a society of agents under the condition that no one
is born with embedded knowledge. In know-nothing word-object pairing, the agents in
communication find meaning until they reach a consensus on what an object should be
called. A language game is a social process of finding agreement on word-object pairing
which enables its communication in a multi-agent system. In this research, techniques
are proposed to discover the association between a word and agents’ beliefs on an object
using self-organizing maps and flexible searching with a cultural algorithm to find the
meaning for concepts in a space that retains the agents’ beliefs in three quality
dimensions represented by colors: red, green, and blue. The techniques were evaluated
in a variety of scenarios using four significant measures: coherence, specificity, success
rate, and word count. The results show that social agents were able to quickly reach
mutual agreement for multiple listeners by searching their social beliefs and using a
cultural algorithm to search for cultural beliefs.
