Peer reviewedTseng, Yuen-Hsien – Journal of the American Society for Information Science and Technology, 2002
Reports an approach to automatic thesaurus construction for Chinese documents. Presents an effective Chinese keyword extraction algorithm. Compared to previous studies, this method speeds up the thesaurus generation process drastically. It also achieves a similar percentage level of term relatedness. Includes three tables and four figures.…
