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.89 leavesapplication/pdfengCultural evolutionComputer games -- Researchtext--thesis--doctoral thesis10.14457/NIDA.the.2016.81
