Abstract

In this paper, we propose an implementation method of an integrated associative search for mathematical expressions. A large amount of information resources for technology and science field have been distributed in wide area networks. In order to realize a media data search for technology and science field corresponding to semantic contents, realization of the associative search method for mathematical expressions is important. This method consists of a similarity expression search function and a semantic associative search function based on the mathematical model of meaning. The similarity expression search realizes a similarity retrieval by user's queries given in some mathematical expressions or symbols. The semantic associative search realizes an associative retrieval by user's queries given in some words for mathematical expressions characterized by metadata represented in words corresponding to their features. This method can realize a multifaceted associative search for mathematical expressions by user's queries which consist of words and mathematical expressions. Applications of this work include some retrieval systems for technical report, academic paper, and libraries for numerical analysis.
