Tagging的分類與知識意涵：以flickr首頁圖片為例

Abstract

Web2.0創造了一個以使用者為中心，多向、由下而上的溝通模式，其中Tagging是由使用者自訂關鍵字的分類方式，它所呈現出的秩序特徵，打破了過去由上層或中心的「專家」決定的權力結構，與傳統的分類學大不相同，但在打破傳統秩序後，Tag展現出怎樣的分類樣貌？這些分類對知識形塑有何影響？需要進一步釐清。本研究以19張flickr首頁相片為本，試圖對其結構散漫的Tags做系統性歸納。研究結果可以看出，Tagging最少有四種主要型態：(1)與主題相關；(2)以公開分享為目的；(3)以私人收藏為目的；(4)情感性標籤，這顯示Tag的命名是功能式的，以「功能」而非「事物」做為分類基礎。而Tag的訂定標準是多重的，不是簡單的二元對立，因此拉近了正統知識分類與日常生活經驗之間的距離，化解了主體／客體、理性／感性、階層／水平之間的界線，把對能指的玩弄，變成為知識創造的一個元素。

The rise of Web 2.0 stimulates a user-centered, bottom-up, and multiply interactive model of communication. One of its key concepts, tagging, the foundation of folksonomy, encourages users to create keywords with natural thoughts. As a result, traditional taxonomy that symbolizes the top-down, expert-oriented power structure is no longer dominating the order of classification, which has significant impacts on our understanding of knowledge construction. This paper empirically examines 19 photos, 324 tags from the flickr homepages. Four main categories are formulated in such unorganized tagging order: (1) those related to the subjects of photos; (2) those tagged for public sharing; (3) those meant to identify as self-collections, and (4) the affective tags. The findings indicate that tags are better categorized in terms of function rather than taxonomical object. Since rational objects and emotional feelings can both be accommodated for classification, tagging in effect minimizes the distance between normalized knowledge and everyday life experience, dissolving the boundaries of subject and object, rational and sentimental, as well as hierarchical and parallel oppositions. It is expected that the play of signifiers will be a significant role in the production of knowledge in the near future.
