Multi-Agent Ontology Mapping framework Based on Evidence Theory for a Question Answering System
This event took place on Monday 06 June 2005 at 12:30

 
Miklos Nagy KMi, The Open University

In my presentation I will introduce an experimental multi agent ontology-mapping framework in the AQUA query answering system that incorporates uncertainty handling inherent to the mapping process. The framework uses Dempster-Shafer theory of evidence for dealing with incomplete and uncertain information produced by the different similarity mapping algorithms. A novel approach is presented how specialized agents with partial local knowledge of the particular domain achieve ontology mapping without creating global or reference ontology. Our approach is particularly suitable fit for a query-answering scenario, where answer needs to be created in real time that satisfies the query posed by the user.

The talk is being hosted by Dr. Maria Vargas-Vera from KMi.

Knowledge Management is...


Knowledge Management
Creating learning organisations hinges on managing knowledge at many levels. Knowledge can be provided by individuals or it can be created as a collective effort of a group working together towards a common goal, it can be situated as "war stories" or it can be generalised as guidelines, it can be described informally as comments in a natural language, pictures and technical drawings or it can be formalised as mathematical formulae and rules, it can be expressed explicitly or it can be tacit, embedded in the work product. The recipient of knowledge - the learner - can be an individual or a work group, professionals, university students, schoolchildren or informal communities of interest.
Our aim is to capture, analyse and organise knowledge, regardless of its origin and form and make it available to the learner when needed presented with the necessary context and in a form supporting the learning processes.
