Recently, the web 2.0 services which appear by exponential extension of the Internet can be expressed with the changes in the quality of structural evolution and in the quantity of increasing users. The structural base is in user participational architecture, the web 2.0 services such as Blog, UCC, SNS(Social Networking Service), Mash-up, Long tail, etc. play a important role in organization of web, and grouping and searching of user participational data in web 2.0 is broadly used by folksonomy. Folksonomy is a new form that categorizes by tags, not classic taxonomy skill. it is made by user participation. Searching based on tag is now done by a simple text or a tag cloud method. But searching to consider and express the relations among each tags is imperfect yet. Thus, this paper provides the relational searching based on tags using the relational graph of tags. It should improve the trust of the searching and provide the convenience of the searching.

정보근로자는 지식 중심의 사회에서 지식을 창출하고 소비하는 핵심적인 역할을 하고 있다. 따라서 지식관리 과정은 정보근로자의 업무패턴을 반영해야 한다. 또한 지식관리 도구는 수;q고 효과적으로 지식을 생성, 통합, 전파 할 수 있도록 지원해야 한다. 그러나 대부분의 지식관리 시스템은 정보근로자를 시스템의 기능으로 다루고 있기 때문에 정보근로자의 업무패턴과 요구사항을 반영하는데 어려움이 있다. 본 연구에서는 정보근로자의 지식관리를 위해 요구되는 협업 정보교환, 정보접근의 중요성을 설명하며, 사회적 소프트웨어 기반의 지식관리 프로세스와 지식 변환 과정을 살펴본다.

This study aims to answer whether social tagging through user collaboration could be utilized for the creation of digital knowledge of the web, and whether we could verify the quality and efficacy of social tagging to obtain benefits from it. In particular, this paper examines the inter-indexer consistency of social tagging in comparison to professional indexing. It employs two different similarity measures, both of which are based on the Vector Space Model to deal with numerous indexers. It contributes to the utilization of social tagging in the organization of the web, and encourages to adopt social knowledge in developing suitable vocabularies for resources newly generated in the digital library environment. Furthermore, the comparative analysis with two different measures produced more credible results by illustrating a similar pattern of indexing tendency in both measures.
