Beyond Web-log: Transform Blog into Personal Expertise and Social Network via myFOAF Support

To utilize the dramatically increasing Blog contents and widely accepted web 2.0 services, this research proposes myFOAF which extends FOAF to model dynamic social contexts over the web. Based on the richer social semantic, we can generate the blogger’s myFOAF profile, via the corresponding contents such as RSS, Blog content, tagging data, mashup service that retrieve from blogger’s daily web behavior. Two main application models are addressed in the system. Firstly, the Personal Expertise Explorer can accumulate blogger’s tagging ontology (myTag) to analyze the blogger’s domain related expertise. The evaluation result shows that the average precision reaches around 77.6%. Secondly, the Personal Social Explorer gathers the blogger’s friend information to form a personalized social network diagram which presents blogger’s social activities in certain tag domain. With the extra semantic supported by myFOAF, blogger can easily explore his own implicit expertise and web social relationship with minimal efforts.
