The ACACIA project is a
multidisciplinary project that aims at offering models, methods
and tools in order to help the knowledge engineer to acquire
(i.e. elicit and model) knowledge from multiple expertise sources
(experts or documents). The purpose is to capitalize expertise on
a given field or to build a knowledge-based system.
acquisition from multiple experts, we defined a protocol for
elicitation of expertise from a group of experts. We proposed a
model of cognitive agent for guiding knowledge acquisition and we
proposed several techniques of comparison of multiple expertise
models: comparison of knowledge graphs, generation of consensus
rules. We also developed an architecture of cognitive agent and a
platform for building multi-agent applications.
We analysed explanatory dialogues among experts solving
cooperatively a problem and we determined the explanatory
strategies appearing in such dialogues. We improved our
explanatory text planner developed last year. We studied a
modelling of evaluation activity.
We proposed techniques for analysing expertise documents, in
order to model the underlying expertise or explanatory knowledge.
We also developed a tool allowing to build conceptual graphs from
electronic documents and managing hypertext links between
elements of documents and the conceptual graphs of a base.
We proposed several methods for acquiring qualitative
knowledge such as topoï and we improved our qualitative reasoning
engine for performing simulations on knowledge graphs, in order
to validate the acquired knowledge.
The project is funded by:
- the French Ministry of Research and Space and the French
Ministry of Equipment, Transportation and Tourism: knowledge
acquisition from multiple experts in analysis of road
accidents. This research is carried out in collaboration with
INRETS and the Paris V University.
- the GENIE project between Dassault-Aviation and INRIA: we
take part in the research on the topics Technical Memory and
Cooperation of heterogeneous applications.
- the Esprit BRA Working Group MODELAGE on A Common Formal
Model of Cooperating Intelligent Agents , coordinated by
the University Notre-Dame de la Paix, Namur, Belgium.
