Blog: Category and Tag

The article classification is easy to manage the article and the article Quick Search, in Pjblog Forum also often mentions the two class classification question, indeed, pjblog at present only supports the first level classification, for the refinement has caused the trouble. But I have some questions about the infinite level of classification that some programs offer, and it's not about efficiency, but it's also difficult to get on the UI. Whether it's a one-time presentation, or a folding pattern, a lot of levels can cause use or visual distress. I personally feel that up to three level can, the general level two can be satisfied.

It reminds me of the Windows Start menu, which is usually two or three, and you'll probably get bored. And when the article is published, it should be allowed to be published in multiple categories, because some of the content is really cross classified. Like cnblogs.com and NetEase blog.

For a number of multi-user programs, system classification and individual classification are necessary, this has two advantages, one is to facilitate the user's personal collation, and increase personal articles in the overall environment of the opportunity to show, some pioneers seem to have all adopted the tag mode, I would like to classify this is necessary, after all, from the fixed thinking of people, The orderly classification of things is a necessary step to the cognition of things. and tag is disorderly, too much tag not only will not bring the cognition of things have a positive impact, but will cause trouble

To this day basically all of the blog system and even cms\forum have features, usage is basically the same
(1) A partial tag display page appears on the homepage, of course some also use flash to make some effect
(2) Another big tag page, listing all the tag, according to the use of the frequency tag display size style is also different
(3) After clicking on a tag, come out a list of related logs

It's basically the pattern.

I saw a little application in the Pjblog, is through tag to view the associated log, Pjblog is a single user blog program, I think if used on multi-user system, can extend to the other users through the tag to see the log

Compared to the classification, tag is more specific, such as we say "tourist scenery" classification, if you really want to divide up, it may be more
Such as:
Tourist scenery--(domestic/overseas)-(province/Municipality)-(county/district), etc.
If divided by this level, it will cause a lot of classification waste, because some counties/districts may not have the relevant articles
But in fact we will generally be divided into two categories, domestic tourism/overseas travel
Then add a specific label to the log, such as: Penglai, the city if the classification will generally go to level three or three
But through tag performance, it can be found in the first level category and linked to other Penglai travel logs.
If you add the label "Shandong", it will widen the relevance of the article.

This is involved to another issue, that is, the choice of tag, an article if given too much tag, then the information is very messy, I have not encountered this problem, an article of the tag generally not more than 5, Generally can be quick to determine the use of the tag. In some multi-user systems, some users have added some popular tags that are irrelevant to the content of the article in order to get click-through, which is also needed for proper monitoring.

Back to the topic of the previous paragraph, I think that the tag is more than auxiliary classification, rather than tag is to strengthen the link between the article or between users, through the use of the article tag, can be the content of the article or users concerned about the content of the link, thereby increasing the interaction between the article or user. In this sense, is not tag also need to classify it? After all, for a multi-user long-running system, the classification may be fixed, occasionally changed, but the number of tags has been growing, at one glance, messy. In particular, the current system home page display (more and more BSP have done so), put a so-called hot log, if the careful observation of these tags basically did not change, because they accumulate will become more and more popular. This is unfair to the new additions to the tag, they may never be shown on the home page, and no one will care. So I think also want to show some add tag, and increase the random display section, so that more tag to get the opportunity to display.

To sum up, I think for a BSP or multi-user CMS system, System classification and individual classification are necessary, but the level is not too much, tag is necessary, but not for the purpose of classification, but to strengthen the article and the article between the user and the user relationship.
