What is SOBOLEO

The novel paradigm of social semantic bookmarking combines the positive aspects of semantic annotation with those of social bookmarking and tagging while avoiding their respective drawbacks; drawbacks such as the lacking semantic precision of tags or the cumbersome maintenance of ontologies. Social semantic bookmarking tools allow for the annotation of Internet resources based on an ontology and the integrated maintenance of the ontology by the same people that use it. This chapter motivates social semantic bookmarking by examining the respective problems of tag based bookmarking and semantic annotation. Social semantic bookmarking is then introduced and explained using the SOBOLEO application as an example. It also gives an overview of existing applications implementing this new paradigm and makes predictions about its movement into the mainstream and remaining research challenges.
