You have to admit that the rapid development of the network today, the speed of information flow, the volume is not considered, but now it is really in front of us. How to accept the information, how to deal with, digest them has become the Internet users have to spend energy to solve the big problem.

"Good memory is not as bad as writing", childhood elders always teach us, but this rule in today, may not have some pace. In this era of information explosion, want to see all the things to read down, where in time; mechanical memory can not help you solve the "organization" problem, learn how to manage information is the King (of course, the "organization" is not referring to from). If you have been able to skillfully search engine, this is a good start, because you find that the dynamic use of keywords, you can quickly find the information you want. The keyword is an index tag.

If this is too abstract, then think about how you are IM, SNS in the classification of friends. First of all, why do you want to classify them? Second, how to classify? 5-4-3-2-1, it's time! To classify friends is to quickly find him in many contacts and save time. In the process of looking for a contact, the category plays the role of an index, which is a shortcut to help you get your positioning done. Again, how do I classify: I divide all the contacts by company and school. When I was at work, I also categorized the company by Circle, and then I found it was so general that I had to remember what role someone was in, and relatively speaking, company attributes were more obvious and easier to remember. Students will not say, if you want to subdivide, school is the best natural attributes. So, the company, the school is an index tag.

How do you classify books? Careful you may find that many of the books on the cover of the book now have "on the shelves: economics", in order for the book to appear in the bookstore's proper classification system, making it easier for readers to find it. This is an index of books that publishers and authors intend to make. The process of this classification is: first there is content, then there is classification. Here to think, in writing a blog, the order should be So, "published" Before the release, give it a "shelf reference", of course, this reference is the category of blog directory, tags (tags). Category directory is the scope of the article, tags (tags) is refined after the content of the keyword, is the title of the supplement, help memory. Therefore, tags (tags) is an index tag.

Movies (DVDs), songs (CDs) themselves with attributes (such as publishing company, director, actor, singer, song name, etc.) is enough to identify the product, and then use tags tag to identify the product is not much meaning. With the nature of the information, you use these properties to index, so as not to "take off the pants fart-the cost two times".

It is worth mentioning that the classification is not only for people to see, but also for the machine to see. Users continue to extract and refine the core keywords to computer learning, so that the machine to do classification, indexing such duplication of work, to help users improve efficiency.
