(FCA) has turned from mathematics towards computer science. This
article provides a review of this new orientation and analyzes why
and how FCA and computer science attracted each other. It discusses
FCA as a knowledge representation formalism using five knowledge
representation principles provided by Davis, Shrobe, and Szolovits
(1993). It then studies how and why mathematics-based researchers
got attracted by computer science. We will argue for continuing this
trend by integrating the two research areas FCA and Ontology Engineering.
The second part of the article discusses three lines of research which
witness the new orientation of Formal Concept Analysis: FCA as a
conceptual clustering technique and its application for supporting
the merging of ontologies; the efficient computation of association
rules and the structuring of the results; and the visualization and
management of conceptual hierarchies and ontologies including its
application in an email management system. ER - TY - CONF AU - Hotho, A. AU - Stumme, G. A2 - Kókai, G. A2 - Zeidler, J. T1 - Conceptual Clustering of Text Clusters T2 - Proc.
