Agent Oriented Data Integration
Gal, Segev et al 2005
This paper (9 pages, plus 28 references) describes the QUALEG application – part of its functionality overlaps with HANDS, so a comparison could be useful. QUALEG is an EC project aimed at increasing citizen participation in the democratic process, partly by providing a data-integration services – ie brining everying together from the user’s point of view, and letting the system work out where to find or send information.
In QUALEG the world is divided into contexts (mapped to ontologies by agent processes within the application; one context can belong to several ontology concepts simultaneously, apparently). The point is, a context allows a word to be understood correctly depending on where it is encountered.
Two key agents are:
- Knowledge extraction agent: language independent – it I guess it must use standard keyword indexing technologies
- Opinion analysis agent: IR and NLP techniques are used to identify topic and opinion.
A nice description of an alternative approach to the problems HANDS is trying to solve.
