Report on past research works Helping

My research so far has been focused on integrating and developing methodologies, techniques, tools and resources to support a precise manual knowledge representation, sharing and retrieval (KRSS). The resulting models, notations and normalization techniques for representing, indexing, querying, evaluating and integrating knowledge are however also important to follow for precision-oriented (semi-)automatic knowledge extraction and integration. From the end of 1992 to the end of 1999, the context of my work was the "semi-independent knowledge representation approach" where knowledge providers do not have to represent their information into a shared knowledge base (KB). This approach is still the only one considered by most knowledge representation, sharing and retrieval (KRSS) related works today. Nonetheless, as detailed below, this approach is very restricting for precise KRSS. Hence, from 2000 to 2007, my work focused more on also enabling people to easily update a very large consistent well-organized KB while avoiding the classic problem of either allowing any user to modify any part of the KB (as in wikis) or having the bottleneck and restrictions associated to the existence of a selection committee.
