How to carry on the Chinese participle in Baidu

I believe that the search engine has been included in the word segmentation technology has been very curious to grasp the search engine segmentation technology for our webmaster's work has a great help: the link structure and keywords in the site layout and Word has a great relationship. Usually with more contact with Baidu, so Baidu Chinese participle as an example to introduce the search engine segmentation method.

　What is Chinese participle?

In understanding the Chinese word of Baidu before we first want to understand what is Chinese participle? Our Chinese and English are different from each Chinese character, so it is comparatively complicated to be divided up. Baidu Chinese participle is a Chinese sentence into a separate word, and then according to a certain rule to regroup into a sequence of the process, referred to as "Chinese cut words." Word of the search engine to help a lot, can help search engine program automatically identify the meaning of the statement, so that the search results match the highest, so the quality of the word segmentation will directly affect the accuracy of the search results. The current Baidu search engine segmentation mainly using dictionary matching and statistics of these two methods.

　Dictionary matching participle

There's an accident with this method. A dictionary with a large vocabulary, that is, a word-segmentation index library, to match the strings of the words to be divided according to certain rules and the words in the thesaurus, finding a word indicates a successful match, mainly through the following ways: Minimal segmentation (the smallest number of words in each sentence); Forward maximum matching method ( Direction from left to right); bidirectional maximum matching method (for two scans from left to right, right to left); Reverse maximum matching method (from right to left direction).

Under normal circumstances, the search engine will use a variety of ways to use, which brings great difficulties for search engines, such as ambiguity processing, in order to improve the accuracy of keyword matching, search engines will simulate the human understanding of the sentence, so as to achieve the recognition of words effect. That is, in the same time of acne, syntax, semantic analysis, the use of syntactic information and semantic information to deal with ambiguous phenomena. This mainly includes the following parts: The general control part, the word breaker subsystem, the syntactic system of French. Under the coordination of the general control part, the segmentation subsystem can get the syntactic and semantic information about words and sentences to judge the ambiguity of word segmentation, that is, it simulates the process of human understanding of sentences.

　Statistics credits words

Although the dictionary indexing library solves many challenges, but writing is still far from enough, search engines also need to have the ability to constantly find new words, in the calculation of the probability of the adjacent word is not a separate word, so the more understanding of the context, the sentence to understand the more accurate, of course, the more accurate participle. For example, is the "search engine optimization process is what" in the context of the number of times, then statistics participle will be the word Word if the index library.

For SEO workers, must master the search engine acne principles and methods, so that the site is easier to determine the relevance of the subject. On the "SEO" and "training", I found that each word participle has a word and an adverb, usually a priority to match the subjects, and then match the adverb, such as here obviously SEO is the subjects, so priority to match the word, and then training this adverb.
