ITTC Project


Accessing Sources with Diverse Ontologies

Project Award Date: 0000-00-00



Description

Individual agents lack a commitment to a common, pre-defined ontology but share a distributed, collective memory of objects. We are developing a system where each agent creates and learns conceptualizations, or ontologies, which are useful for its individual purposes, but it also shares its knowledge to improve group problem solving performance. Our work shows that multiagent learning of ontologies among individual agents with diverse conceptualizations is feasible and these learned ontologies can be used by the agents to improve group search performance for related semantic concepts through experience in the problem domain.

In our work we use supervised inductive learning to learn semantic concept descriptions in the form of interpretation rules. Each source agent contains a description of the information and knowledge contents of the resident source and a representation of the concept hierarchy it is familiar with. A representation hierarchy can contain bookmarks, or URLs, pointing to a semantic concept object, or Web page. Each set of bookmarks in a hierarchy is used as training instances for the semantic concept learner. The semantic concept learner learns a set of interpretation rules for all of the agent's known semantic concept objects. An entire set of these types of semantic concept descriptions can then be used for future semantic concept interpretation.


Investigators




Partner with ITTC

The Information and Telecommunication Technology Center at the University of Kansas has developed several assistance policies that enhance interactions between the Center and local, Kansas, or national companies. 

ITTC assistance includes initial free consulting (normally one to five hours). If additional support is needed, ITTC will offer one of the following approaches: 

Sponsored Research Agreement

Individuals and organizations can enter into agreements with KUCR/ITTC and provide funds for sponsored research to be performed at ITTC with the assistance of faculty, staff and students.

Licensing and Royalty/Equity Agreement

An ITTC goal is the development of investment-grade technologies for transfer to, and marketing by, local, Kansas, and national businesses. To enhance this process, the Center has developed flexible policies that allow for licensing, royalty, and equity arrangements to meet both the needs of ITTC and the company.

Commercialization Development

Companies with a technology need that can be satisfied with ITTC's resources can look to us for assistance. We can develop a relationship with interested partners that will provide for the development of a technology suited for commercialization.

ITTC Resource Access

ITTC resources, including computers and software systems, may be made available to Kansas companies in accordance with the Center's mission and applicable Regents and University policies.
