Novelty retrieval auxiliary system embedded in scientific and technological innovation process:development and practice of thesaurus in sci-tech novelty retrieval field in Northeastern University Library
This paper investigates the technology of constructing domain thesaurus and the method of generating specialized thesaurus.Based on the arrangement of academic keywords by artificial experts in existing novelty retrieval reports,it is proposed to construct an auxiliary system of subject words in sci-tech novelty retrieval domain embedded in sci-tech innovation process.With the help of this system,the functions of semantic matching and automatic expansion of novelty retrieval keywords,mining potential topics of related documents and intelligent extraction of search words can be realized,so as to better carry out sci-tech novelty retrieval services and improve novelty retrieval efficiency and intelligent level.
