Search engine background segmentation based on a separator or dictionary to close the

Users in the search engine and press Enter after typing the keyword, the search engine in the background first determine whether the word spaces, punctuation, etc., if any, the keyword search engine will once again broken down into several small keyword analysis, if the background is not delimited in accordance with the sub-dictionary for key words segmentation.

I’ll give an example, such as we in the Baidu search “Ningbo SEO”, click on a snapshot of the number one web site, Baidu will be used in the snapshot of the two words marked in different colors , such as “Ningbo” is yellow, “SEO” is light blue.

Told us this example, we search for “Ningbo SEO” when Baidu split it into “Ningbo” and “SEO” used queries. If the middle “,” the results of the query is the same. This is why the time to write more than two key words in English suggest that you use a comma to separate half-width, so the search is to avoid repeated analysis attentions. Chinese word segmentation technology relative to other languages to be more difficult, as it is, regardless of the word with no spaces, unlike the English each word has a space, which gives the search engine is very great difficulties, did not we think simple. At present Chinese word segmentation technology, Baidu still better than Google’s.
