Abstract:
The topie search’s eore is the contents of the mateh which is based on the Chinese word segmenta.tion , but the Chinese word segmentation’s aeeuraey and unregistered word’s reeognition is still the bouleneckof the topie seareh. This paper proposed an improved maximum matching of word segmentation algorithmIMMM. In improved algorithm designed thesaurus pretreatment, unknown word proeessing and disambiguationstrategy, combined subjeet categories and sub-word dietionary storage , finally construet a topie search systemThe algorithm results show that the improved algorithm is better than traditional algorihms, and the search ae.curaey rate has been greatly improved, The system’s efficieney is improved.
