Title
¬The application of PRECIS in indexing Chinese documents : an experimental study

Abstract
Describes a study aimed at exploring possible applications for PRECIS for indexing Chinese documents, generating Chinses subject indexes, and for facilitating online information retrieval. A random sample of 498 Chinese subject indexing strings was taken from the Index to Chinese Periodical Literature and a comprehensive test of the PRECIS role operators was carried out. 18 problem areas were isolated and grouped into 8 categories. These problems stemmed mainly from syntactic differences between English and Chinese. Suggests modifications of and additions to the existing role operators and the accompanying software to overcome these problems
