A corpus-based statistical approach to automatic book indexing

摘要

[[abstract]]©1992 ACL-The paper reports on a new approach to automatic generation of back-of-book indexes for Chinese books. Parsing on the level of complete sentential analysis is avoided because of the inefficiency and unavailability of a Chinese Grammar with enough coverage. Instead, fundamental analysis particular to Chinese text called word segmentation is performed to break up characters into a sequence of lexical units equivalent to words in English. The sequence of words then goes through part-of-speech tagging and noun phrase analysis. All these analyses are done using a corpus-based statistical algorithm. Experimental results have shown satisfactory results.
