网站制作内容的推送、寻找、分类、筛选的方式有以下四种形式分类，或多或少的，同时并存。
Website content push, search, classification, screening way has four kinds of classification, more or less, at the same time.

一、用户自选(Users customize)

这一种方式用户具有最大的主动权，网站通过设计清晰的分类导航和站内搜索系统，让用户通过自己的意愿，在网站上寻找到他需要的内容信息。
This way the user has the initiative the biggest, site classification through navigation and search system design is clear, let users through their wishes, to find he needs information on the website.

优点：条理清晰，简便有效。
缺点：是否能找到精确的信息，一方面取决于用户对信息的归类方式和搜索关键词的组织，一方面取决于网站对信息的归类和关键词的组织。如果两方对同一内容的需求和理解不一致，，一个信息内容，网站归如A类别，用户认为B类别可以找到，那么一定是无功而返。那么这个信息应该打A,B两个Tag，归入两个类别。搜索也是同样的缘故，要在搜索的索引中将可能被用户查询的信息都提供完全。最后，大量的分类和冗杂的搜索信息积累下去，反而又从精确变成了模糊。于是人们发现，各大搜索引擎上的关键词越来越长。
Advantages: clear, simple and effective.
Weaknesses: if you can find the exact information, on the one hand depends on the user of the information classification and search keywords organization, on the one hand depends on the website for information classification and keyword organization. If the two party needs and understanding of the same content, inconsistent, an information content, such as web site to A category, B category of users that can be found, then it must be failed. This information should be playing A, B two Tag, fall into two categories. Search is the same reason, in the search index may be a user query information provided is complete. Finally, classification and miscellaneous large search information accumulation, but also from the exact into fuzzy. So people found, each big search engine keyword more long.

总结：作为最基础的方式，没有网站不会提供这个功能，至少都有对信息的分类导航。
Summary: as the most basic way, no site does not provide this function, at least the classification of information.

二、审核匹配(Audit matching)

审核是指对内容进行审核筛选，诸如通过评分体系，浏览量，点击率，时间和等等其他一些因素，给与大量同类信息进行排序和权重区分，来判断这个内容对用户的需要程度高低，在分类列表或者搜索结果里，将最可能的用户需求信息最先或者最明显陈列给用户。
Audit refers to the audit selection of content, such as by scoring system, the quantity that browse, click rate, time and so on some other factors, sort and weight to a large number of similar information to distinguish, to judge the content of the needs of the user level, in the category list or search results, user demand information will most likely the first or the most obvious display to the user.

优点：为第一种方式做补充，通过规则对信息进行排序和过滤，降低大多数用户的搜寻成本。
缺点：这是一种少数服从多数的匹配方式，即默认需要信息的用户是“大多数用户”，忽视和无视“少数用户”的需求。而评分体系也有体系的问题，让用户进行评分，并不会产生理想化分数，专业评分又缺乏性。关于商品分数的问题，我在另外一篇文章里做过讨论——现有商品的评分体系不完美另外，YouTube也得出了结论说，评分的分布并非理想化的。
Advantages: as a supplement for the first way, through the rules for sorting and filtering of information, reduce the most users search cost.
Disadvantages: it is a way of matching the minority is subordinate to the majority, which is the default need information of the user is " most users, " and not " a small number of users " demand. The scoring system also has the problem of the system, allowing users to score, and produce ideal will not score, score and the lack of professional. About the commodity the score, I in another article discussed -- existing goods scoring system is not perfect in addition, YouTube also draws the conclusion that, the distribution is not ideal score.

总结：在这个匹配体系里，最大需求被最大满足，最小需求被无视，从损益综合来讲是最优解，但是当这个社会的个性化需求越来越强烈的时候，长尾上的用户需求就没有明显的顺序了，完全是一小撮用户有一小撮不同的需求，而且他们加起来就是一个不可忽视的长尾，怎么给他们推送内容信息呢。
Summary: in this matching system, the maximum demand is the biggest meet the minimum requirements, be ignored, from the income in general is the optimal solution, but when the personalized needs of more and more intense, the long tail of the user needs no obvious sequence, is entirely a handful of users have a handful of different needs, and they add up to is a can not ignore the long tail, how to give them a push content information.

三、个性化匹配(Personalized matching)

通过多维度的了解用户的偏好，对用户的信息需求进行匹配。喜欢喝果汁的人通过“苹果”这个词首先查看的是“苹果汁”相关信息，而一个“果粉”通过“苹果”这个词首先找到“苹果电脑”。怎样去定义一个用户个性维度，一般有两种方式。
Through the multi-dimensional understanding of user preferences, to match the user's information needs. Like to drink juice of the people through the " apple " this word the first view is the " apple juice " related information, and a " powder " through the " apple " the word first find the " apple computer ". How to define a user personality dimensions, there are two general ways.

一种叫做“物以类聚”：
One kind is called " like attracts like ":

是通过它喜欢的内容来预估。豆瓣在个性化匹配上做的很不错，它能给用户推非常精准的书籍，电影等等。所以豆瓣需要先了解你喜欢的是什么类型的内容，你需要不断的积累你喜欢的内容，它就越精准的将相似的内容给你。
It is predicted by the content of love. The bean in the personalized match do very well, it can give users very accurate books, movies and so on. So the watercress need to understand your love is what type of content, you need to continue to accumulate what you like, it is more accurate to similar content to you.

另外一种是“人以群分”：
Another is the " birds of a feather flock together ":

通过你的交际圈来预估。信息的传统流转途径就是通过“群分”的人来进行的，信息共享首先是在圈子和圈子内，兴趣相同的人之间传播，所以这是一个朴素的方法，通过互联网技术提高了传播效率。豆瓣也会告知用户他的好友在关注的东西和搜集的信息，最典型的还是类似开心网这样以人际关系为基础的SNS网站。你的朋友们显然比计算机算法更了解你，他们主动推荐给你，或者他们自己喜欢的信息，相信你也会感兴趣。
Predicted by your social circle. The traditional circulation way of information is through the "groups " people for, information sharing is the first in the circle and circle, the spread between people of the same interest, so this method is a simple, through the Internet communication technology improves the efficiency of. Bean also informs the user about his friends in things and collect information of concern, the most typical is similar to happy net that based on interpersonal relationships of SNS website. Your friends than the computer algorithm to learn more about you, they take the initiative to recommend to you, or they like information, I believe you will be interested in.

优点：更精准的匹配，也更加有效
缺点：马太效应（Matthew Effect），好的愈好，坏的愈坏，多的愈多，少的愈少。举一个例子来说明，我在Google Reader订阅了大量的UED相关的blog，结果它就自动推荐UED相关的blog给我，但是我已经订阅够了，我倒是很想看一些写八卦小文的订阅源，但是很难找到。我也不能通过”写八卦小文的订阅源“这个关键词找到合适的Blog。
Advantages: matching more accurate, more effective
Disadvantages: Matthew effect ( Matthew Effect ), good better, bad worse, much more, less and less. As an example, in my Google Reader subscribe to a lot of UED related to blog, it will automatically recommend UED blog to me, but I already have a subscription is enough, I'd like to see some writing a gossip message feeds, but it's hard to find. I can't write by " gossip Xiaowen feeds " the keywords to find the right Blog.

总结：最精准，但是最容易走偏锋。
Summary: the most accurate, but the easiest Zoupian front.

四、无差别推送(No difference push)

所谓无差别就是，管你是谁，都给你们传递一样的信息。
There is no difference is, whoever you are, you have to pass the same information.

优点：省事，直接，干脆
缺点：容易被用户厌恶
总结：也有效果
Advantages: simple, direct, simply
Disadvantages: easy to be sick
Conclusion: there are effects

大体上，我总结出来的就这四种方式，各有优劣，至于如何运用，在不同的情景则有不同的具体方式，这个多一些，那个多一些。
On the whole, I summed up the four kinds of style, have their pros and cons, as for how to use, in different scenarios are detailed in different ways, the more, the more.
