A fuzzy FCA-based approach for citation-based document retrieval

In this paper, we propose a fuzzy FCA (formal concept analysis) based approach to conceptual clustering for citation-based document retrieval. In the proposed approach, fuzzy logic is first incorporated into FCA to form a fuzzy concept lattice that can handle vague and uncertain information. A fuzzy conceptual clustering technique is then performed to cluster the fuzzy concept lattice into conceptual clusters and construct a concept hierarchy. Fuzzy query can then be formulated for document retrieval. The proposed fuzzy FCA-based approach has been applied to a citation database for fuzzy document retrieval. The performance of the citation-based document retrieval system is evaluated and presented in the paper.
