Abstract

This paper describes a new framework consisting of two mechanisms: one for building a rich vocabulary based on a lexical semantics, and the other for evaluating queries using such a vocabulary. A vocabulary built by the former mechanism has the following two features: (a) richness because of its expandability, and (b) the lexical-semantic definability of its words. Query expressions using such a rich vocabulary satisfy the following two properties: (c) no need to use nested queries, and (d) no need to use variables. In our framework, each vocabulary consists of basic words and derived words. A derived word can be defined as a character string label given to an expression that combines already defined words with operators. When someone defines a large vocabulary with all of its basic words being mapped to an ontology of the underlying Semantic Web, users can query this Semantic Web using this vocabulary.
