　　Background information:

Mr. Policy----------------"world famous Shoes Taobao" promotion contest special judges

In the first quarter of the promotion competition during the performance of the contestants weekly concise comments, the tyranny of difficult diseases, for a number of contestants know. A low-key and mysterious, dedicated to the site for several years to promote. Current second Titzen "world famous shoes Taobao guest" promotion contest judges, whereabouts is not very clear.

Speaking of Chinese participle, I think as long as the friends involved in SEO should understand this knowledge, understand how the search engine is how to identify the relationship between words and words, how to distinguish the meaning of the statement. Because you only fully understand, through the application of Chinese participle can be in the keyword collection, analysis, layout, including the title of Save write more handy, will write more excellent soft text. Chinese word segmentation has been the core knowledge of SEO knowledge.

Seoer must understand how search engines work is particularly important and fundamental.

We first understand the concept of Chinese participle, what is Chinese participle?

Chinese word segmentation technology belongs to Natural language Processing technology category, for a word, people can through their own knowledge to understand what is the word, which is not a word, but how to make the computer also understand? Its processing is the word segmentation algorithm.

At present, the search engine for Chinese word segmentation can be divided into three categories: based on string matching word segmentation method, based on the understanding of the word segmentation method and statistics based segmentation method.

　　1. Segmentation method based on string matching

Search engine in the user's search when the first will judge the user search "word" and the database inside the "word" is matched, how to scan the matching degree;

According to the input "keyword" or "sentence" different length priority matching situation, can be divided into maximum (longest) matching and minimum (shortest) matching;

As follows:

1 forward maximum matching method (from left to right direction);

Example: The "world famous Shoes Taobao customer" promotion contest.

is the largest cut out of the key words: The world famous shoes Taobao customers, promotion contest (not on the map, everyone Baidu, and then look at the snapshot can)

2 Reverse Maximum matching method (from right to left direction); This is the same as the 1th word participle, but the key words before and after the order, in search engine database query results are the same.

3) Minimum segmentation (so that the number of words cut in each sentence is the smallest);

Example: The "world famous Shoes Taobao customer" promotion competition

The least cut out the word is: the world, the name of shoes, Taobao Guest, promotion, competition;

4 Two-way maximum matching method (from left to right, from right to left two times scan)

　　2, based on understanding of the word segmentation method

The method of Word segmentation is to make the computer simulate the people's understanding of the sentence, to achieve the effect of recognizing words. The basic idea is to make syntactic and semantic analysis at the same time, and use syntactic information and semantic information to deal with ambiguity phenomenon. This approach has been against the long-term pseudo original practice, in the 09 general exchange of synonyms, synonyms of the false original Baidu will be included, to the 2010-year pseudo original amplitude need to do more to be effective, in the end of this year's June, a big update Baidu, many students found the original collection of stations, or false original strength of the Web page content by a large number of Baidu released, not included, indicating that the technology method of Baidu is more and more mature, more and more perfect. False originality is more and more difficult.

　　3. Segmentation method based on statistics

In terms of form, words are a combination of stable words, so the more times the adjacent words appear in the context, the more likely they are to form a word. Therefore, the frequency or probability of adjacent words and characters can better reflect the credibility of the word. Search engine through this method in the "Drop-down box" or "related search" can be fully mentioned. In recent years, we have found that a lot of network companies have a business is "brush Baidu Related keywords", when the user input a keyword, we can do to specify in the Baidu Drop-down box appear to want the keyword, using this is based on the statistics of the principle of participle.

Finally, the key words in the application of the title, understanding the relationship between Chinese participle and site title.

　　1, search terms and site title exactly match

When the user in Baidu search, search terms if and your site title exactly match, and your site has reached a certain weight when there will be a good ranking, this also explains the title must appear keyword, is the reason, conversely, if the search word does not match your site title exactly when the search engine on the word , participle of the way to participate in the Chinese word segmentation principle of the integrated approach.

　　2, search words do not match before the word segmentation

When words and your site title does not match the time will be participle, participle of the way will participate in, positive, reverse, statistics, understanding, synonyms, as well as new words and ambiguous words. This time the search engine understanding will be more difficult, thus affecting the ranking of the page;

Speaking of which, before I mention in a clean Taobao guest contest Exchange QQ Group 189321234 sent some Taobao hot search keywords out, in the last Dream Jiang and I an interview in a clean Taobao guest said these words in Taobao search a lot, but in Baidu's words is almost zero, at that time I suggest optimization "industry words + Strategy, industry words + leather shoes "This type of keyword, but also said that I will write the article specifically to clarify, I would like to give an example, I hope to be more clear point."

　　Title: Leisure shoes strategy Empoven, fashion men Korean version of the Wind

According to the largest matching method: Leisure shoes, Empoven, fashionable men, Korean version of the Wind. It contains at least "leisure shoes, leisure shoes, Empoven, the smart shoes Wave wen" These 4 words, so as to optimize the popular word in Baidu "leisure shoes", precision words: leisure shoes, but also optimized in Taobao hot word precision word "Empoven, the Smart shoes wave wen", As far as possible to do with the user search word matching degree is high, I said that is the meaning.
