Dear DL and KR Community Members,<br>
<br>
we are happy to announce that the next Description Logic Seminar will take place on <strong>January 9, 2026, at 2pm</strong> via Zoom.<br>
Our next speaker is <strong>Sebastian Rudolph</strong> from <strong>TU Dresden</strong> and the topic of the talk is "<strong>Multiperspective Reasoning in KR Formalisms via Standpoint Logic</strong>".<br>
<br>
<em>Abstract:</em><br>
The importance of taking individual, potentially conflicting perspectives into account when dealing with knowledge has been widely recognised. Many existing knowledge management approaches fully merge knowledge perspectives, which may require weakening in order to maintain consistency; others represent the distinct views in an entirely detached way. This talk presents an alternative, referred to as Standpoint Logic, a simple, yet versatile multi-modal logic “add-on” for existing logical languages – including Description Logics – intended for the integrated representation of domain knowledge relative to diverse standpoints, which can be hierarchically organised, combined, and put in relation with each other. My talk will introduce the general logical framework of Standpoint Logic and discuss variations which differ in expressivity and computational complexity of automated reasoning.<br>
