Abstract
This paper firstly shows the necessity of meaning-based search by analyzing the constraints of keyword-based search, i.e., query strings are unfaithful to query intention and multiply divergent expressions are used to express a query intention. Then through setting some technical restrictions on “meaning” and “same meaning”, it proposes a meaning-driven and generalized keyword-based search approach: constructing synonymous expressions to capture the meaning of a given query string and generate multiply query strings for simultaneous search. Finally, it illustrates how to investigate the Chinese synonymous expressions comprehensively, and extract some heuristic rules for recognizing the synonymous forms of a given query string.
