doxyer Liu's List: Web 2.0 理论

    • The central focus of a folksonomy is for personal refindability and derived from that point we get great value.
      • Flickr 只有作者能对照片提供 tag, 不能告诉你还有谁也用同样的 tag 来描述同一照片. 因此, 在 Flickr 中 tag 是一种作者分类工具, 一种搜索关键字, 但不是一种大众分类工具.

    • the broad folksonomy, as a tool like del.icio.us delivers
    • lends itself very easy to applying the power law curve (power curve) and/or net effect to the results of many people tagging. The power terms and the long tail both work.
      • 要有足够多的不同类型的人来tagging, 才能见到 Power curve 和 long tail.

    • Folksonomy (also known as collaborative tagging, social classification, social indexing, and social tagging) is the practice and method of collaboratively creating and managing tags to annotate and categorize content. Folksonomy describes the bottom-up classification systems that emerge from social tagging.[1] In contrast to traditional subject indexing, metadata is generated not only by experts but also by creators and consumers of the content.
    • Flickr may not be a good example of folksonomy

    • The obvious disadvantage of this approach is its lack of precision (synonym/antonym control, related terms, context, etc), but in most practical usage scenarios the trade-off between simplicity and precision makes sense.
      • 也许更好的做法是结合两者, 设计者提供一个简单的概略的不强制的层次结构描述, 使用者再添加自己的 tags.
        又或者, 象 BBmao 那样, 在搜索结果中自动提取关键字(tag). 还可以进一步让用户来评价这些提取出的关键字.

    • It is an excellent illustration of the advantages offered by simple, emergent and iterative systems over old-skool top-down communications software

    • Tags are a "bottom-up" type of classification, compared to hierarchies, which are "top-down". In a traditional hierarchical system (taxonomy), the designer sets out a limited number of terms to use for classification, and there is one correct way to classify each item. In a tagging system, there are an unlimited number of ways to classify an item, and there is no "wrong" choice. Instead of belonging to one category, an item may have several different tags.
      • 觉得用的最好的是 Flickr
        如何用于个人数据管理? Gmail / GReader ?

    • Search engines can then index them to make relevant materials related to the event searchable in a uniform way. In this case, the tag is part of a controlled vocabulary.
      • 一种不太常见的用法: Controlled Vocabulary

    • 股市大衰退通常标志着蒸蒸日上的技术已经开始占领中央舞台。假冒者被驱逐,而真正成功的故事展示了它们的力量
    • 所谓互联网先驱和O'Reilly公司副总裁的戴尔·多尔蒂(Dale Dougherty)注意到,同所谓的“崩溃”迥然不同,互联网比其他任何时候都更重要,令人激动的新应用程序和网站正在以令人惊讶的规律性涌现出来

    • 从界面元素上总结 Web 2.0 的特征. 但, 我以为, Web 2.0 的特征是用户贡献内容并有效关联信息(如"喜欢...的还喜欢...") - doxyer Liu on 2009-01-14
    • 在这里发现 Stumbleupon 新增了一个 "Related Sites" 功能, 从而找到了History of Graphic Design 2008 http://designhistory.org/ - doxyer Liu on 2009-01-14
    • 技术正在将大规模市场转化成无数小市场
    • 人们正在细查目录,在长长的候选名单中寻找目标——这样多的选择在百视达音像店和托尔唱片店是看不到的。
