A software tool designed using the concepts of swarm intelligence and text mining is proposed as an aid in the analysis of free/open source software (FOSS) development communities. A prototype of the tool collects textual data from an electronic mailing list, a primary mode of FOSS developer communication. The tool enables a user to compare patterns of discussion topics found in the text with patterns of swarm intelligence. The research of this design is congruent with Madey et al.‟s (2002) observation that the open source software development phenomenon shows an emergent behavior and can be modeled after agent-based, biologically-inspired swarms. The goal of a tool for identifying emergent intelligence on FOSS mailing lists is to increasing the user‟s understanding of a given FOSS development community.
