We present a novel approach to the automatic acquisition of taxonomies or concept hierarchies from a text corpus. The approach is based on Formal Concept Analysis (FCA), a method mainly used for the analysis of data, i.e. for investigating and proces

Item does not contain fulltext In this paper, a multi-agent simulation model is presented to investigate the dynamics of 'mutual-support networks': online social networks consisting of both humans and artificial agents. Via such networks, human users
