Abstract: Organizing concepts from large amounts of text requires a sophisticated technique. Traditional manual methods create products, such as thesauri, that have no word-sense ambiguity, but they have difficulties in keeping up with advances of knowledge development. Automatic methods that are based on term frequencies and co-occurrences, such as clustering and neural networks, in contrast, create collection-dependent products, but they cannot resolve the word-sense ambiguity problem. To develop a better concept organization technique, this study found a solution by combining the strengths of manual and automatic methods and mitigating the weaknesses of both. Based on the "subsumption" rule developed by Sanderson and Croft (1999), the dissertation has developed "Probability of Co-occurrence Analysis" (POCA) for automatic concept organization. Concept hierarchies generated by POCA are intended to provide users with an overview to concepts in a text, and the hierarchical structure of the overview represents frequencies and co-occurrences of concepts. |
