Problems solved by technology

[0005] The suffix tree clustering method still has some areas to be improved in the process of processing. For example, if the original document is too long, the computer will require more time for processing; there is a lot of redundant information in the text, and the computer needs to process these texts. Consumes a lot of computing resources
Different types of text have obvious differences in the structure of words, and it is obviously not the best choice to treat them in the same way

Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] In order to illustrate "a suffix tree clustering method based on word segmentation and part-of-speech analysis", here is an example of processing and clustering the document "A.txt". Each of A.txt contains an introductory sentence about "basketball", the specific content is: "Basketball is a ball game played by two teams, and each team has 5 players."

Abstract

The invention provides a suffix tree clustering method on basis of word segmentation and part-of-speech analysis. The method involves three parts, namely a document word segmenting module, a part-of-speech analyzing module and a suffix tree clustering module, accomplishes word segmentation, part-of-speech tagging, word weight calculation and essence extraction to a document, can realize dimension reduction process to an original document, reduces the complexity of the processing procedure of the suffix tree clustering method, and meanwhile, ensures the clustering accuracy.

Description

technical field [0001] The invention relates to a suffix tree clustering method based on word segmentation and part-of-speech analysis applied to search engines, and belongs to the technical field of computer science. Background technique [0002] With the continuous development of information technology, the data on the network is increasing at an alarming rate, and people's demand for network content is also increasing. Network content search has become the most widely used Internet service at present. The search engine is the main channel for network content search, and all countries are developing search engines with independent intellectual property rights, and are constantly conducting research on key technologies of search engines. [0003] The content on the Internet involves all aspects, and there is a large amount of unorganized and uncategorized information, which has caused certain difficulties for people who want to quickly obtain information on specific aspects...
