MatchmakingMatchmaking is the process of finding and

matching correspondences between two ontologies (i.e. matching a waste with a technology/solution).

Matchmaking is an area of research.Existing matchmakers are not suitable to be

used as they are. Alterations are required.

Upper OntologiesAre ontologies that describe very general concepts.Can help in sharing and re-using.Can help in matching.

For that reasons the UoS team is developing such an ontology for the Industrial Symbiosis domain.It describes the main concepts used in Industrial

Symbiosis along with the general properties that describe those concepts.

The following conceptual model is a first draft of the upper ontology for eSymbiosis.

Demo OntologyThe following demo ontology has been

developed.This ontology will be used to:

Test the functionality of the web application.Identify any issues or needs.Test the potential use of an upper ontology.Test the matchmaking facility.To serve as a common language between the

consortium members.

• After establishing the requirements for the web platform the UoS team will:

Develop a light weight ontology (i.e. an ontology based on the classifications) that will capture the knowledge in the domain of waste stream and solution provider technologies.

Enrich the ontology by adding properties and restrictions in order to facilitate IS practice.

Integrate to our system any existing ontologies that can be useful in describing the knowledge of the IS domain.

Next StepsNext Steps


• The matchmaking algorithm will be developed and tested in parallel with the ontology development.

• The ontologies will be regularly tested against the matchmaker and the web platform with collaboration with the other partners.
