描述.Explorations in Automatic Thesaurus Discovery. presentsan automated method for creating a first-draft thesaurus from rawtext. It describes natural processing steps of tokenization, surfacesyntactic analysis, and syntactic attribute extraction. From theseattributes, word and term similarity is calculated and a thesaurus iscreated showing important common terms and their relation to eachother, common verb--noun pairings, common expressions, and word familymembers. .The techniques are tested on twenty different corpora ranging frombaseball newsgroups, assassination archives, medical X-ray reports,abstracts on AIDS, to encyclopedia articles on animals, even on thetext of the book itself. The corpora range from 40,000 to 6 millioncharacters of text, and results are presented for each in theAppendix. .The methods described in the book have undergone extensive evaluation.Their time and space complexity are shown to be modest. The resultsare shown to converge to a stable state as the corpus grows. Thesimilarities calculated are compared to those produced bypsychological testing. A method of evaluation using ArtificialSynonyms is tested. Gold Standards evaluation show that techniquessignif

https://doi.org/10.1007/978-3-030-95806-0ne concept in a variety of ways. This variability raises the question of how the computer can know that words a person uses are related to words found in stored text? Any computer-based system that employs a natural, rather than an artificial, language in its dialogue with human users is faced with this problem.

Evaluation,ompare words and produce list of similar words. Visual inspection of these lists gives the intuitive impression that the words on this lists are related. The purpose of this chapter is to demonstrate in some objective manner that the relationships extracted are what are commonly considered considered as semantic relationships.

Conclusion,motivation of this approach: the . problem that affects any computer-based manipulation of text, e.g., information retrieval, filtering, language understanding, human-computer interfaces, machine translation. This problem generated much research in computer-based semantics, a portion of which we reviewed before we presented our system SEXTANT.
