| Abstract: | To achieve precise retrieval of massive information in network environment, firstly it is necessary to ensure that there are no ambiguous words in the literature indexing words. A lot of ambiguous words often are produced in Chinese automatic indexing process, and leads to retrieving irrelevant or missed information. This paper focuses on the related research on methods of eliminating the crossed meanings ambiguous words in the automatic indexing and puts forward a method to eliminating ambiguous words combined algorithm of exhaustive method and disambiguation rules. Experiments show that the method can avoid a great lot segmenting ambiguities with better segmenting results. |
