An Approach to Automatic Indexing of Scientific Publications in High Energy Physics for Database SPIRES HEP

摘要

We introduce an approach to automatic indexing of e-prints based on apattern-matching technique making extensive use of an Associative PatternsDictionary (APD), developed by us. Entries in the APD consist of naturallanguage phrases with the same semantic interpretation as a set of keywordsfrom a controlled vocabulary. The method also allows to recognize withine-prints formulae written in TeX notations that might also appear as keywords.We present an automatic indexing system, AUTEX, which we have applied tokeyword index e-prints in selected areas in high energy physics (HEP) makinguse of the DESY-HEPI thesaurus as a controlled vocabulary.
