Hybrid Search over Korean Web Contents

Keyword search suffers from some limits: ambiguous keywords, synonymous words, and an inability to recognize semantic constraints. Semantic search helps resolve these issues but is limited by the quality of annotations which are likely to be incomplete or imprecise. Hybrid search, a search technique capitalizing the merits of both keyword and semantic search, appears to be a promising solution. In this paper we describe Hybrid search over Korean web contents by using HyKSS, a hybrid search system driven by extraction ontologies for both annotation creation and query interpretation.
