分类目录是什么意思?

分类目录是将网站信息系统地分类整理,提供一个按类别编排的网站目录,在每类中,排列着属于这一类别的网站站名、网址链接、内容提要,以及子分类目录,可以在分类目录中逐级浏览寻找相关的网站。

分类目录中往往还提供交叉索引,从而可以方便地在相关的目录之间跳转和浏览。也可以使用关键词进行检索,检索结果为网站信息,这种检索也称之为网站检索。

分类目录专案效仿一些在20世纪最重要的编辑员/志愿者项目。就像牛津英文字典通过志愿者的努力成为权威的工具一样,Open Directory跟随着它的脚步也成为了权威的互联网分类目录。


分类目录介绍:

含义

分类目录专案是建立在开放资源共享的理念上的,是唯一100%免费的大型目录。提交一个网站或使用目录数据不需要支付任何费用。开放目录专案的数据在同意遵守我们免费使用条款的情况下,任何人都可以免费使用,但是有很多权重比较高的分类目录一般网站是很难提交成功的,比如DZ目录、谷歌目录、雅虎目录等著名的分类目录,想要让这些比较知名的分类目录收录,条件比较高和苛刻。

类似于图书馆分类方式的主题目录。比如搜狐分类目录,先按主题分成十八个大类目,再进一步细分为二级三级子类目。

分类目录是互联网上查找信息的在线指南。分类目录的编辑把所有的中文网站资源整理后组织起来,按不同的主题放在相应的目录下,从而形成网站分类目录体系。

以图书分类编码检索标志的目录体系。卡片按分类号的顺序排列。分类目录是从知识体系方面揭示图书馆藏书。中文的图书分类法主要有《中国图书馆图书分类法》(简称《中图法》)、《中国科学院图书馆图书分类法》(简称《科图法》)、《中国人民大学图书馆图书分类法》(简称《人大法》),西文的图书分类法主要有《杜威十进分类法》(简称《杜威法》)和《美国国会图书馆图书分类法》(简称《国会法》)。《国际图书集成分类法》。研究者要尽快查找到所需,就得熟悉图书分类法。

衍生含义

网站分类目录是指:把所有网站人工或系统进行分开,分开到各个相应的目录下。

分类目录是指通过人工的方式收集网站资源,并把这些拥有一定价值的网站资源通过人工的方式对他们的主题进行整理组织之后,存放到相应的目录下面,从而形成的网站分类目录的体系。

搜索引擎非常重视高质量分类目录这样的外部链接,因此,我们在进行seo的时候一定要重视起来。但是对于低质量的分类目录,搜索引擎不但不重视,甚至会把它纳入链接目录的范围,一旦被认为是链接农场,不管是目录链接本身,还是被链接的目标页面,都会比较危险的。链接农场就是指那些大量存放低质量链接的低质量网站或者页面。

分类目录,使其成为我们的外部链接,那么我们的网站也就会在对应的搜索引擎里得到较高的权重。比如百度比较重视hao123,tm312,谷歌重视ODP,而雅虎更加重视的就是自己的雅虎分类目录,分类目录具有单向性和高质量性等特点,中国的数以十万计的导航网站也就是我们用不尽的资源。

概念辨析

分类目录和搜索都是用户查找网站信息的工具。区别在于查找信息的方式不同,分类目录是把同一主题网站信息放在一起并按一定顺序排列,通过主题目录层层找到的,如搜狐的分类目录;搜索是用户不通过目录,直接用关键字词来查询,找出与某关键字词对应的所有网站信息(并按其相关性排列),如百度搜索。另外,分类目录拥有可供浏览的树状结构,并可按主题层层点击下去。例如:您想找有关游戏“天堂”的信息,你可以通过分类目录“娱乐休闲>游戏>网络游戏>多人在线游戏>天堂”找到有关天堂的多条网站信息;你也可以不通过目录,直接在搜索框中输入关键词“天堂”,点击搜索,即得到有关天堂的所有网站信息。

这两种查找方式结果的区别:通过目录查找得到的这一百多条网站信息都是经过编辑审核确认后推荐给大家的,信息量小但很精;通过搜索得到的结果是互联网上所有与“天堂”相关的网站信息(但不一定是游戏“天堂”,如天堂饭店等),信息量大但相关性较差。

以下是英文翻译版解释意思:

What does a catalog mean?

Classified directory is to systematically classify and organize website information and provide a website directory arranged by category. In each category, there are website names, website links, content summaries and sub classified directories belonging to this category. You can browse and find relevant websites step by step in the classified directory.

Cross index is often provided in the classified directory, so that it is convenient to jump and browse among related directories. Keywords can also be used for retrieval. The retrieval result is website information, which is also called website retrieval.

The cataloging project follows some of the most important editorial / volunteer projects of the 20th century. Just as the Oxford English dictionary has become an authoritative tool through the efforts of volunteers, open directory has also become an authoritative Internet catalog in its footsteps.

Catalog introduction:

meaning

The catalog project is based on the idea of open resource sharing and is the only large catalog that is 100% free. There is no charge for submitting a website or using catalog data. The data of open directory project can be used for free by anyone who agrees to abide by our free terms of use. However, there are many categories with high weight, which are difficult to submit successfully for general websites, such as DZ directory, Google directory, Yahoo directory and other famous categories. If you want to include these well-known categories, the conditions are relatively high and harsh.

A subject catalogue similar to the library classification. For example, Sohu's catalog is divided into 18 major categories according to the theme, and then further subdivided into two and three sub categories.

Catalogues are online guides to finding information on the Internet. The editor of the classified catalogue organizes all the Chinese website resources and puts them under the corresponding catalogue according to different themes, thus forming the classified catalogue system of the website.

The catalogue system of searching marks by book classification and coding. The cards are arranged in the order of classification number. The classified catalogue reveals the library collection from the aspect of knowledge system. Chinese book classification mainly includes Chinese Library Book Classification (hereinafter referred to as "Chinese Library Classification"), Chinese Academy of Sciences Library Book Classification (hereinafter referred to as "science map law"), Chinese people's University Library Book Classification (hereinafter referred to as "human law"), western book classification mainly includes Dewey Decimal Classification (hereinafter referred to as "Dewey law") and American Library Classification Library of Congress book classification law (referred to as "Congress law"). International Book integrated classification. Researchers need to be familiar with book classification to find out what they need as soon as possible.

Derivative meaning

Site classification directory refers to: all sites manual or system to separate, separate to each corresponding directory.

Classified directory refers to the system of Web site classified directory, which is formed by collecting web site resources manually and organizing these valuable web site resources manually and then storing them under the corresponding directory.

Search engines attach great importance to external links such as high-quality catalog, so we must pay attention to them when we do SEO. But for the low-quality catalog, search engines not only do not pay attention to it, but even put it into the scope of the linked catalog. Once it is considered as a link farm, whether it is the catalog link itself or the linked target page, it will be more dangerous. Link farm refers to those low-quality websites or pages that store a lot of low-quality links.

Catalog, make it our external link, then our website will also get a higher weight in the corresponding search engine. For example, baidu pays more attention to hao123, tm312, and Google pays more attention to ODP, while Yahoo pays more attention to its own Yahoo classification directory, which has the characteristics of unidirectionality and high quality. Hundreds of thousands of navigation websites in China are also our inexhaustible resources.

Concept analysis

Catalog and search are both tools for users to find information about websites. The difference lies in the different ways of finding information. The classified directory is to put the information of the same subject website together and arrange it in a certain order. It can be found layer by layer through the subject directory, such as the classified directory of Sohu. The search is to find all the website information corresponding to a key word (and arrange it according to its relevance) without the directory, such as Baidu search Rope. In addition, the category directory has a tree structure for browsing and can be clicked down by subject level. For example: if you want to find information about the game "paradise", you can find multiple website information about paradise through the category directory "entertainment and leisure > Games > Online Games > Multiplayer Online Games > paradise"; or you can directly enter the keyword "paradise" in the search box without the directory, and click search to get all website information about paradise.

The difference between the results of these two search methods: the more than 100 website information obtained through catalog search is recommended to everyone after being reviewed and confirmed by the editor, with small amount of information but very fine; the results obtained through search are all the website information related to "paradise" on the Internet (but not necessarily the game "paradise", such as Paradise Hotel, etc.), with large amount of information but poor correlation 。

Typical website editor

In the early 21st century, the world's relatively large categories such as: YY category, cloud category, webmaster category, webmaster category, Yahoo category, Google category, baidu category
