Résumé
Relational Concept Analysis (RCA) is one variant of Formal Concept Analysis for multi-relational dataset exploration. The tool RCAExplore is an implementation of the RCA process where several choices can be made before each iteration: the structure to be used (con-cept lattice, AOC-Poset, Iceberg lattice), the scaling quantifier (exist, forall, contains, percentage-quantifiers, etc.), and the considered formal and relational contexts. RCAExplore was developed during Fresqueau ANR 11 MONU 14 project, in order to explore relational hydroecolog-ical data, and has also been used on several datasets in different other domains. The source code and a standalone jar application are available online. An integration of the tool is ongoing within a platform for data exploration and knowledge representation.
