| Abstract: | The semantic environmental with special stop -words location information control has been studied and founded. This technology has been applied to Chinese metadata CXMARC text automatic indexing and the data mining of theme information. The algorithm of SWF that is used in the pretreatment special Chinese text automatic indexing can reduce the participle different meanings of a field efficiently and shorten indexing time. So tradition maximum matching algorithm has been improved of its quality and efficiency. |
