Electric text similarity processing method and system convenient for query

Abstract

Disclosed is an electronic text processing method convenient for query and search, and retrieval or search system of similar contents comparing process device comprising keyword search. The invention makes a comparison among similar contents in the delimitation limit of various text keyword search, determining and classifying similar contents depending on whether which have similarities, so as to perform the executions such as separating subsets, arranging various sequences or forming directories, sorting, displaying interface and the like. The invention can considerably improve the convenience and tightness of information retrieval or network information search.

Description

(1) Technical field [0001] The present invention relates to computers and search engines related to electronic text processing and retrieval or search technology. (2) Background technology [0002] In the past 20 years, computer database retrieval technology has developed greatly, especially the progress of network technology such as the Internet, which has made the scale of databases that people can share reach astronomical figures. In order to make it easier for users to find the information or files they need, classification or directory retrieval systems have emerged. This technology is more suitable in the mature classification field that people are very familiar with, but in the wider field of massive information, it is difficult to establish and difficult to master and use. [0003] Keyword search as the core retrieval technology and search engine technology brings convenience to users. The system can obtain the keyword query request of the inquirer through the inte...

Problems solved by technology

However, this technique has serious drawbacks

[0007] The first is that the amount of calculation is too large, especially when the content of each text to be compared is large and the number of texts is large, more calculation time will be required

Some targeted improvement technologies that have been proposed, such as Yahoo's No. 6990628 US Patent related to "measurement of electronic text similarity" technology, IBM's Chinese patent CN1112647 C's "response query to classify documents in document collections "system and method" technology of Fudan University's Chinese patent CN1220159C "a high-dimensional vector data fast similarity retrieval method" technology, Hewlett-Packard's Chinese patent CN1269064 C technology on "document and information retrieval method and equipment" , Baidu's Chinese patent CN1209726C about "a method for identifying mirror image and quasi-mirror image websites on the Internet" only performs a similar comparison of the home page, and has made very limited improvements to the first defect above

[0008] The second defect is that the results of similarity processing are often of limited help to the queryer, because although similar files have obvious commonalities, there are also certain differences, and the information that the queryer is interested in is likely to be Where there are differences, key differences tend to significantly affect the class of the text

Existing technologies, including U.S. Patent No. 6990628, cannot identify whether a certain difference or similarity between two texts is important, so the search results provided by such technologies are neither rigorous nor convenient
