Using query expansion for cross-lingual mathematical terminology extraction

Abstract

The paper presents approach to knowledge discovery by using query expansion to search for cross-lingual mathematical terminology extraction. It employs information retrieval and statistically-based techniques to extract and process keyword collocations in large comparable cross-lingual web electronic text corpora in the domain of mathematics in Bulgarian and in Serbian language. It, also, offers examples and survey of used techniques for semantic search and clustering by comparing keyword collocations to build a cross-lingual thesauri. The results of semantic keyword search for the two web electronic text corpora using Sketch Engine software are presented and analyzed with respect to the types of keyword collocations processing and to multilingual application of the approach.
