Two-phase Query Modification using Semantic Relations based on Ontologies.
Kaoru Hiramatsu, Jun-ichi Akahani, Tetsuji Satoh · 2003
We propose two-phase query modification using ontologies for geographic information navigators. The query modification is divided into two phases: 1) revising ambiguous conditions into appropriate ones automatically to obtain an adequate number of search results, and 2) providing next available options to enable users to jump to advanced and associated topics. Both phases are processed using semantic relations based on ontologies and conduct users to query evolution interactively. While processing, our prototype system outputs search results in various styles, such as digital maps and tables, so that it enables users to have a good understanding of the relational structures among the search results. In this paper, we explain an outline of the prototype system and examine the effect of the query modification through an example.
