This paper proposes an algorithm combining statistics with rules,called the priority merger algorithm,which merges phrases by calculating the relationship of words,checks phrases by using phrase rules and a semantic dictionary in grammar and semantics,and recognizes Chinese phrases by the means of hierarchic analysis.

Through building it′ "semantic dictionary" module and " primitive-feature base" module in retrieval system, have finished the organic integration of two kinds of retrieval methods and improved the performance of image retrieval system on existing technical level.

To compute the semantic relatedness of words,a frequently-used method is to use the classified semantic dictionary.

Having established relevant extension set for every sense of ambiguous words,we acquire automatically the linguistic knowledge about ambiguous words from the large scale corpus by the sense words in the extension sets,and build the unsupervised word sense disambiguation model.

In this paper,we discuss image fusion methods within the space domain,transform domain and intelligence domain, where the emphasis is given to the fusion method based on image segment,wavelet transform,its extension,and semantic predication.
