Establishment of 'The Multiple Thesaurus of Chinese Classification' and Using Its Application to Improve the Retrieval Efficiency in the Chinese Bibliographic Databases

摘要

Due to the limitations of Chinese character set in the windows operating system, homophones, pictographic characters or pinyin are often used to replace the complex traditional Chinese characters or any characters that haven't been designed in the character set of the Computer Operating System; as an investigation shows the item of subject in most bibliographic databases is not complete; there are various kinds of classification schemes co-exiting in the bibliographic database, which is very common in the merged universities and regional union catalogues. These problems have greatly affected the efficiency and sharing of digital service. To improve the retrieval efficiency within the present situation in the bibliographic databases, we can design a "multiple thesaurus" i.e. the "Database of Classification Reference" including two classifications and design new method of retrieval for the computerized management of libraries.
