On the pros and cons of Chinese word segmentation matching and perfect matching

Just spent 4 per week of Baidu Small update, the author of the site's ranking dropped a lot down. and friends Liu Minhua personal Blog but quickly occupy the position in front of me. Why to write this article today, because the friend's website has not been updated recently, and the snapshot update is very delayed. On the contrary, the author's website is a daily update, and the snapshot is also very long, why will this problem arise. Later I took this to consult Zhu Weikun teacher. There are two points of knowledge in the conversation. Chinese word segmentation matching perfect match

　　

Chinese word segmentation matching is divided into string matching participle, understanding word segmentation method, statistical participle method. The most commonly used for string matching, in the string matching is subdivided into the forward maximum matching method, the reverse maximum matching method, the least segmentation, bidirectional maximum matching method. Specific content you refer to Baidu Encyclopedia, or the author's personal blog inside a detailed explanation.

Perfectly matched, literally, to a deep understanding. is a touch of the same, such as the search for the author's name "Lee Chin" then in the Baidu home page must be "Lee Chin" this name is linked together, not "Li xxxxx gold xxx Dragon"

The main problem today is to analyze the differences between Chinese word segmentation and exact match. As above the main, friends of the site through the complete match beyond the author's website, then why he would go beyond it? Please look down.

Does the exact match have an advantage over the Chinese word segmentation?

The answer is yes, for example, to search for "what to eat in the morning," it's obvious to see that the front is exactly the same, and we look down again, constantly appear floating red words are no longer "what to eat in the morning", there are more "what to eat in the morning" "What To Eat" "What to eat in the morning" Then perhaps everyone will understand its meaning.

Some people may ask, there is not exactly a match on the home page ah, so here I give an example of the same post to different places, you can see their ranking position, then you will think that they can be together side of the position. Obviously impossible, Baidu also has its calculation method, such as all kinds of tools mentioned in Baidu weight. Do you think weight 1 can be compared with weight 6, which is obviously impossible.

The exact match must be better than the Chinese participle.

The answer is no, the world is not absolutely good, the same exact match is also the case. For example, the title of a website is written like this.

"Today I want to eat what thing, today I want to buy what clothes, today I want to see what movie, today I want to listen to what song, today I want to see what book ... XX Net "

"Today I want to eat something _ buy what clothes _ See what movies _ Listen to what songs _ Read what book ... XX Net "

For the above example, I think more people prefer the following title. As for why, I want to read it more smoothly! Aside from everything else, the title of the site gives people a different time to browse, and for the memory cost is also a gap, as a corporate brand site, if your site's name is very long, I think your brand to a certain extent is more difficult to do. And in Baidu's optimization guide is clearly proposed, all the user experience primarily. So here's what you want to say, and then decide what you're going to do.

A rough introduction of so two points, in fact, summed up that is to want the flow then you go to do exactly match, want to brand then use Chinese participle matching, here also thank Zhu Weikun Teacher's hard to explain.
