Information Technology (IT) is often employed to put knowledge management policies into operation. However, many of these tools require human intervention when it comes to deciding how the knowledge is to be managed. The Sematic Web may be an answer to this issue, but many Sematic Web tools are not readily available for the regular IT user. Another problem that arises is that typical efforts to apply or reuse knowledge via a search mechanism do not necessarily link to other pages that are relevant. Blogging systems appear to address some of these challenges but the browsing experience can be further enhanced by providing links to other relevant posts. In this chapter, the authors present a semantic blogging tool called SEMblog to identify, organize, and reuse knowledge based on the Sematic Web and ontologies. The SEMblog methodology brings together technologies such as Natural Language Processing (NLP), Sematic Web representations, and the ubiquity of the blogging environment to produce a more intuitive way to manage knowledge, especially in the areas of knowledge identification, organization, and reuse. Based on detailed comparisons with other similar systems, the uniqueness of SEMblog lies in its ability to automatically generate keywords and semantic links.
Chapter Preview


Work on Sematic Web is usually related to ontologies (Swartout & Tate, 1999). This has been discussed by Warren (2006). Warren also elicited a knowledge management environment that starts from a scenario and then utilizes technologies along the way to fulfill a particular knowledge management purpose. Warren reported that, with the right technologies induced, Sematic Web works well as a search mechanism. Stojanovic and Handschuh (2002) introduced a real-life application approach to the Sematic Web by building a framework using the existing tools in the Sematic Web and enhanced it to cater for practical problems.

Haystack (Karger & Quan, 2004) provides a rigorous semantic blogging system that can handle inter-links from different blogs. The project has been reported as a successful Sematic Web prototype. One of its interesting features is the introduction of an RDF-encoded blog in order to test how blogging activities can benefit from this RDF representation.

The three efforts mentioned so far have impressed upon us the need to build more practical Sematic Web applications. We therefore chose to explore possible contributions towards the blogging environment with potential applications for knowledge management. Like Haystack, we aim to connect blogs that are semantically related. However, we aim to make this process more independent without much user effort. In other words, we aim to automate this process through knowledge identification and organization, mainly via text categorization.
