A Topic map-based ontology IR system versus Clustering-based IR System: A Comparative Study in Security Domain


By murray - Posted on 18 October 2008

Most clustering methods for information retrieval application do not work efficiently when dealing with complicated data. In this paper, we compare the performance of the Topic Maps-based method with the Clustering-based method. An experimental test was carried out using 20 volunteer to evaluate and compare the performance of the Topic Maps-based Information Retrieval system and Clustering-based Information Retrieval system in security domain. The experimental results show that a Topic Maps-based method provides both better recall/precision and shorter search time/search steps.
