Abstract: This paper describes an approach for extracting and representing the knowledge generated from collaborative interaction of small learning teams that work together in distance to carry out a software project or a case study. Our approach is based on ontology, Social Network Analysis (SNA) and fuzzy classification, which has been initially developed as a mechanism to analyse and understand behavioural patterns from collaboration performed in different scenarios. Through the SNA we are able to define an ontological profile that provides a deep knowledge about the participants| roles, intentions and effects; hence a fuzzy model can perform inferences over individual indicators.

Keywords: collaboration; social networks; computer supported collaborative learning; ontology; CSCL; social network analysis; SNA; fuzzy classification; fuzzy modelling; small learning teams; knowledge extraction; knowledge representation.
