SemDis Roadmap

There are two important research issues in SemDis as the following: collecting knowledge and sharing knowledge.

Semantic Web Technology Evaluation Ontology (SWETO)

Objectives

1. create ontology for describing the semantics of web entities and their relationships
2. collect the population of the ontology from online knowledge sources

Implementation  (semi-automatically/ automatically)

1. designing the SWETO schema using an ontology design toolkit
2. identifying knowledge sources that can be used to populate parts of SWETO
3. utilizing extractor agents (written by humans without programming using a toolkit) to periodically and automatically extract parts of knowledge from various open and public sources,
4. semi-automatically disambiguating the knowledge (with limited human involvement)
5. integrating related knowledge to populate the SWETO
6. providing ability to export SWETO in RDF/RDFS and a version of OWL.

Web of Belief (WOB)

Objectives

1. create ontology for a distributed web of knowledge which is connected by social relations among agents and knowledge statements
2. provide trust based knowledge propagation  mechanisms in the web of belief
3. enforce privacy preserved knowledge sharing

Implementation

1. design a extensible WOB ontology
2. create a peer to peer knowledge sharing framework using semantic web service technology. The framework includes: personal web service, knowledge source web service, and robot web service.
   1. personal web services use and produce personal knowledge. They are created by human users. FOAF profiles can be used to establish user network
   2. knowledge source web services "produce" knowledge in RDF/XML format. The SWETO extractor agents can contribute many such web services.
   3. robot web services derives knowledge from existing knowledge. e.g.  auction service, and reputation service.
3. trust can be used to enforce privacy protection in knowledge sharing
4. provide the knowledge query interface to the public
