Relational Exploration is a dialogue-based method for structurized specification of relational knowledge in terms of a description logic knowledge base. The underlying technique is attribute exploration known from formal concept analysis.

Coupled with description logic reasoners, this method can be used to create or refine OWL ontologies. In collaboration with my colleague Johanna Völker, this method was combined with lexical ontology learning approaches and implemented in the tools RELExO and RoLExO.

Relational Exploration has been thoroughly described in my PhD Thesis

From the Cover

Facing the growing amount of information in today's society, the task of specifying human knowledge in a way that can be unambiguously processed by computers becomes more and more important. Two acknowledged fields in this evolving scientific area of Knowledge Representation are Description Logics (DL) and Formal Concept Analysis (FCA). While DL concentrates on characterizing domains via logical statements and inferring knowledge from these characterizations, FCA builds conceptual hierarchies on the basis of present data. Relational Exploration is a method for acquiring complete relational knowledge about a domain of interest by successively consulting a domain expert without ever asking redundant questions. This is achieved by combining DL and FCA: DL formalisms are used for defining FCA attributes while FCA exploration techniques are deployed to obtain or refine DL knowledge specifications.
