Case-Based Reasoning (CBR) solves problems by reusing past problem-solving experiences maintained in a casebase. The key CBR knowledge container therefore is its casebase. However there are further containers such as similarity, reuse and revision knowledge that are also crucial. Automated acquisition approaches are particularly attractive to discover knowledge for such containers. Majority of research in this area is focused on introspective algorithms to extract knowledge from within the casebase. However the rapid increase in Web applications has resulted in large volumes of user generated experiential content. This forms a valuable source of background knowledge for CBR system development. In this paper we present a novel approach to acquiring knowledge from Web pages. The primary knowledge structure is a dynamically generated taxonomy which once created can be used during the retrieve and reuse stages of the CBR cycle. Importantly this taxonomy is pruned according to a clustering-based sense disambiguation heuristic that uses similarity over the solution vocabulary of cases. Algorithms presented in the paper are applied to several online FAQ systems consisting of textual problem-solving cases. The goodness of generated taxonomies is evidenced by improved semantic comparison of text due to successful sense disambiguation resulting in higher retrieval accuracy. Our results show significant improvements over standard text comparison alternatives.
