Inner chain: implies means to add links to relevant text in the content of your website and link to related pages within the website. Reasonable site inside the empty link construction, can enhance the search engine's collection and the website weight. Relative to external links, internal links are also important.

Traditional way

When we used to make a fuss about the system or press release system, the Inner chain (label), usually through the following ways to achieve:

Database: Aspires (Article table) field (ID, title, body, Adddate, userid), keyword (inside list) field (ID, name, link)

In the release of the article, the loop within the list of all, to replace the body of the article.

It does achieve the desired functionality, but if we have a large number of data in our inner list, such as 2W, 5W, or more. The efficiency of each post and revision is conceivable. Then NetEase's news, Baidu's encyclopedia and so on how to hit a large web site is how to achieve it? If you follow the above approach, the system will collapse in a few months.

Analysis and comparison

How many words will there be in a normal article (excluding HTML code)? 1W? I think the 1W article is already very long, and would like to be in a page if directly in the 1W article believe that few people have the patience to read. For the sake of the page and the user experience, editors are usually divided into articles, or chapters, that have too much content and are very lengthy. If we can be in advance may appear in the chain of words from the article extracted, and then retrieved from the database, so the efficiency can be greatly improved? The answer is yes. We take 1 W word article, assume that all text of the article need to chain, the number of cycles is 1W times. Much better than the example above?

In the traditional way, whether you want to, put the contents of the list all over the side. And the following kind of thinking is in advance will be likely to appear in the chain of words all sorted out, and then use these words to retrieve the linked list respectively. Such a comparison problem comes out.

The new idea is: from the article to take out the words need to the chain, and then to query the list.

Feasible operation

For the moment, we call the traditional way passive and the new way of thinking as the active way.

The implementation of the active method is as follows.

The use of Chinese word segmentation technology, we can have an article for participle. Then, according to the vocabulary after the word, filter out the common possessive pronouns, adverbs, exclamations and so on. Put nouns, brands, place names, trademarks and so on, or according to their own thesaurus table to participle. Then the remaining words to retrieve the list, if there is, we do link, does not exist on pass.

The above is only a preliminary idea, in the actual implementation process need to consider a lot of factors. I think the key point is in the segment.
