Abstract

As more users are willingly participating in the creation of web contents, flat folksonomy using simple tags has emerged as a powerful instrument to classify and share a huge amount of knowledge on the web. However, flat folksonomy has semantic problems, such as ambiguity and misunderstanding of tags. To alleviate such problems, many studies have built structured folksonomy with a hierarchical structure or relationships among tags. However, structured folksonomy also has some fundamental problems, such as limited tagging to pre-defined vocabulary for new tags and the timeconsuming manual effort required for selecting tags. To resolve these problems, we suggested a new method of attaching a categorized tag (CT), followed by its category, to web content. CTs are automatically integrated into collaboratively-built structured folksonomy (CSF) in real time, reflecting the tag-and-category relationships by majority users. Then, we developed a CT-based knowledge organization system (CTKOS), which builds the CSF to classify organizational knowledge and allows us to locate the appropriate knowledge.

웹 2.0 환경에서는 사용자 참여를 통한 지식 생산이 증가하고 있으며, 이러한 지식들을 효과적으로 분류하고 공유하기 위한 방법으로 태그 기반의 단일 폭소노미가 활용되고 있다. 그러나 단일 폭소노미를 구성하는 태그들은 단일 태그로 구성되어 있어 그 의미가 불명확하다. 이를 위해 태그간의 관계성이 명시된 구조화된 폭소노미를 구축하는 연구들이 진행되었다. 그러나 이러한 연구들에서도 태그의 의미를 정의하기 위해 미리 정의된 용어집을 사용하기 때문에 용어집에 없는 새로운 태그는 정의할 수 없고, 수작업으로 태그의 의미를 정의할 때 시간이 소요되는 문제점이 발생하였다. 본 연구에서는 사용자가 태그를 입력할 때 입력된 태그가 속할 수 있는 카테고리를 미리 정의된 용어집 없이 자유롭게 정의할 수 있는 카테고리형 태깅 방식을 제안하고자 한다. 또한 사용자들로부터 수집된 카테고리형 태그들을 이용하여 다수의 사용자가 생각하는 태그의 관계를 구조화된 폭소노미에 반영하는 기술을 언급하고자 한다. 끝으로 본 연구에서 제시한 방법들이 조직의 지식 분류와 검색에 활용될 수 있음을 증명하기 위해, 카테고리형 태그 기반의 지식조직체계를 시스템으로 구현하였다.
