Knowledge Representation (KR) is a research area at the borderline between Computer Science and Philosophical Epistemology. Technically KR can be described as a division of Artificial Intelligence focused on prospective information and communication technologies aiming at the efficient use of large data sets.  On the other hand, knowledge and its representation is a central theme of philosophical reflection and analysis; this remark concerns not only the traditional philosophy but also the Analytic philosophy of the 20th century, which essentially uses formal logical methods.  The participants discussed new epistemic practices made possible by new computer-based technologies of knowledge representation.
