Epistemic Planning (Dagstuhl Seminar 17231)

Authors: Chitta Baral, Thomas Bolander, Hans van Ditmarsch, and Sheila McIlrath

Published in: Dagstuhl Reports, Volume 7, Issue 6 (2018)

Abstract

The seminar Epistemic Planning brought together the research communities of Dynamic Epistemic Logic, Knowledge Representation and Reasoning, and Automated Planning to address fundamental problems on the topic of epistemic planning. In the context of this seminar, dynamic epistemic logic investigates the formal semantics of communication and communicative actions, knowledge representation and reasoning focuses on theories of action and change, and automated planning investigates computational techniques and tools to generate plans. The original goals of the seminar were to develop benchmarks for epistemic planning, to explore the relationship between knowledge and belief in multi-agent epistemic planning, to develop models of agency and capability in epistemic planning and to explore action types and their representations (these originally separate goals were merged during the seminar), and finally to identify practical tools and resources. An additional goal explored during the workshop was the correspondence between planning problems and games.

Answering Why and How questions with respect to a frame-based knowledge base: a preliminary report

Authors: Chitta Baral, Nguyen Ha Vo, and Shanshan Liang

Published in: LIPIcs, Volume 17, Technical Communications of the 28th International Conference on Logic Programming (ICLP'12) (2012)

Abstract

Being able to answer questions with respect to a given text is the cornerstone of language understanding and at the primary school level students are taught how to answer various kinds of questions including why and how questions. In the building of automated question answering systems the focus so far has been more on factoid questions and comparatively little attention has been devoted to answering why and how questions. In this paper we explore answering why and how questions with respect to a frame-based knowledge base and give algorithms and ASP (answer set programming) implementation to answer two classes of questions in the Biology domain. They are of the form: "How are X and Y related in the process Z?" and "Why is X important to Y?"
