algorithm testers, in fact, word segmentation is not Baidu's strengths, but by third-party technology in the sub-word search on the site itself, mainly through the segmentation of content words and function words in the segmentation, useful for users to find words for these words are often called key words, through the understanding of word segmentation, so that we can effectively enhance the Web site specified keywords, but also help to improve the site's ranking!
segmentation algorithm is usually for the purposes of Baidu, Google because of the word segmentation is not sensitive, so in the Chinese search market, Baidu has been the leader, the result is often more useful to users, so if we do Website Optimization mainly for the Chinese population, then the understanding of the segmentation technique Baidu is very necessary! Below we explain the specific Baidu, Segmentation!
general, Baidu's Chinese word segmentation is based on two dictionaries and statistical matching, these two methods are not alone, but interrelated and influence each other!
one: a dictionary-based matching method
This is a user's search terms based on dictionary words in accordance with the split, if they can match the success of how can a word cut into one, and then under the direction of the differences, this word is divided into forward and reverse Two matching, in a positive match, and words of different length in accordance with further divided into the maximum matching and minimum matching in two ways! that matches the word segmentation technique depends mainly on the integrity of the dictionary and the latest The updates!
for this segmentation technique, we are doing SEO optimization, when the choice of target keywords in the page with this on principle will not be able to man-made words, unless you can create the "divine horses are clouds "word can be popular in river north and south, it is impossible to get traffic, even if you can increase your site's ranking to the home page, it does not work either! but also for unfamiliar words, Baidu's search results may not return The results, therefore your site will not be included, so the choice of keywords must be based on commonly used words, words to the dictionary to choose!
II: segmentation based on statistical methods
word segmentation of this approach, the search engine will need a lot of calculations, such as the probability of neighboring words and word on how, where a phrase that appears in the most user a word or words in the search time will Find the kind of content, this is judged based on the standard search engine, this method can react quickly to new words, such as when a hot news when the word appeared, many people will use this new term to search for the word, such as small month, such as drug Jiaxin, etc., if the search engines indifferent to these terms, then the user must not use such a rubbish search engine!
In this case, we can do SEO optimization, taking fully into account the relevance of the content of our Web site to be a simple example that A5, when the A5 when it first appears, the search engines certainly do not know What is the word we all use the A5 when the word search, and all hope of finding the ADMIN5 this site, along with natural search engine will calculate their own statistics, and then be able to A5 as admin5! It is a relevant of magical effect, there is the mule driver nets go to the market network, the use of word segmentation is a very nice play battle!
about Segmentation we discussed this, although relatively simple, but for SEO optimizers we still have some reference for the meaning! hope that we can easily complete search engine optimization, so that their site as quickly as possible profit! side effects of L-carnitine from the original paper A5 starting at: http://www.jianfeizhan.net reproduced please specify.
