Hele-Mai Haav, Tanel-Lauri Lubi · 2001
Abstract. In order to solve the problem of information overkill on the web current information retrieval tools need to be improved. Much more intelligence should be embedded to search tools to manage effectively search, retrieval, filtering and presenting relevant information. This can be done by concept-based (or ontology driven) information retrieval, which is considered as one of the high-impact technologies for the next ten years. Nevertheless, most of commercial products of search and retrieval category do not report about concept-based search features. The paper provides an overview of conceptbased information retrieval techniques and software tools currently available as prototypes or commercial products. Tools are evaluated using feature classification, which incorporates general characteristics of tools and their information retrieval features.
