Determination of Relevant Links

At this stage, the problem is not the connection with the Data Base

Management System but the identifi cation and the choice of relevant

attributes among the database schema. They should satisfy the better

relevance criteria. The identifi cation is therefore equivalent to determine

the Relevant Links (RL). In that sense, we propose to classify the RL in

order to facilitate the search.

Several formalisms exist to handle a classifi cation, such as graph-based

or logic-based paradigms for example (Bedel et al. 2007). We propose to

use a lattice of concepts for the classifi cation of RL. Foerster et al. (2010)

and Messai et al. (2008) modify the lattice structur ...
