SOBOLEO is the acronym for Social Bookmarking and Lightweight Engineering
of Ontologies. The system's goal is to support people working in a certain domain in
the collaborative development of a shared index of relevant web resources (bookmarks)
and of a shared ontology that is used to organize the bookmarks. That means, collected
bookmarks can be annotated with concepts from the ontology and the ontology can be
changed at the same time.

SOBOLEO consists of four major parts:

1. a collaborative real time editor for changing the ontology,
2. a tool for the annotation of web resources,
3. a semantic search engine for the annotated web resources, and
4. an ontology browser for navigating the ontology and the index of the web resources.

The users within one community create and maintain a single shared ontology (according to the SKOS Core Vocabulary) and a single shared index of web resources collaboratively. If they encounter a web resource, they can add it to the bookmark index and annotate it with concepts from the SKOS ontology for better later retrieval. If a needed concept does not exist in the underlying ontology or is not suitable, the users can modify an existing concept or use arbitrary tags, which are automatically added to the ontology. In this way, new concept ideas are seamlessly gathered when occurring and existing ones are refined or corrected (maturing phase 2). The users can structure the concepts with hierarchical relations (broader and narrower) or indicate that they are "related". These relations are also considered by the semantic search engine. That means, the users can improve the retrieval of their annotated web resources by adding and refining ontology structures.

The tool is being developed at FZI. An online demo of SOBOLEO is available.
