英文摘要 |
There are more than 70,000 keywords that have not be compiled into the keyword database of the URICA cataloging module. This module was combined with the Chinese Subject Headings and Chinese Classification Scheme in 1999, increasing the content of these databases to 290,000 keywords. However, the keywords still have to be manually reviewed, assessed and revised to ensure error-free searches and to meet reader needs.
The compilation and revision work involves deletion of verbs, adjectives, conjunctions, prepositions, time adverbs, idioms, words with unclear meaning, words with prepositions, words with Japanese and simplified Chinese characters, non-subject words, and words that do not denote a single meaning or subject. All other words will be retained. |
