MAPPING KNOWLEDGE DOMAINS - Combining Symbolic Relations with Graph Theory

Abstract: We present a symbolic and graph-based approach for mapping knowledge domains. The symbolic component relies on shallow linguistic processing of texts to extract multi-word terms and cluster them based on lexico-syntactic relations. The clusters are subjected to graph decomposition basing on inherent graph theoretic properties of association graphs of items (authors-terms, documents-authors, etc). These include the search for complete minimal separators that can decompose the graphs into central (core topics) and peripheral atoms. The methodology is implemented in the TermWatch system and can be used for several text mining tasks. We also mined for frequent itemsets as a means of revealing dependencies between formal concepts in the corpus. A comparison of the frequent itemsets extracted on each dataset and the structure of the central atom shows an interesting overlap. The interesting features of our approach lie in the combination of state-of-the-art techniques from Natural Language Processing (NLP), Clustering and Graph Theory to develop a system and methodology adapted to uncovering hidden sub-structures from texts.
