PAS: A Pervasive Annotation System for Web Resources

The traditional annotation technologies focus on the content of the resources which is normally done by the system managers. There are some web applications which allow users to annotate the resources besides the content; we call this phenomenon as pervasive annotation. This paper defines the pervasive annotation as a correlative procedure of tag assignation, rating, description and usage status marking to the web resources. This paper investigates these pervasive annotation technologies and discusses their usage in the personalized services such as recommendation and presentation. We design and implement a Pervasive Annotation System (PAS) using Service Component Architecture (SCA). The application of this system shows that PAS can help user manage the web resources more conveniently and efficiently by pervasive annotation, and get required web resource recommended through information filtering.
