We will talk about logic programming under the answer set semantics extended with preferences on rules. First, we will concentrate on principles, key properties, that one can expect a semantics for logic programs with preferences to satisfy. We will show connections between the principles and evaluate existing semantics w.r.t. principles. Then we will focus on understanding preferences as a mechanism for encoding exceptions between rules, and express requirements on semantics for such understading of preferences in terms of presented principles. We wil conclude that none of the existing semantics satisfies the requirement. Finally we will present a semantics that satisfies all the requirements.

Latest revision as of 15:39, 10 December 2014

The regular bi-weekly seminar of the KR Group headed by Ján Šefránek on TBA in room TBA. General subject of the seminar are interesting and relevant research issues in Knowledge Representation. The group members report their recent research results.

Everyone is welcome, including students. See also the rules.

We will talk about logic programming under the answer set semantics extended with preferences on rules. First, we will concentrate on principles, key properties, that one can expect a semantics for logic programs with preferences to satisfy. We will show connections between the principles and evaluate existing semantics w.r.t. principles. Then we will focus on understanding preferences as a mechanism for encoding exceptions between rules, and express requirements on semantics for such understading of preferences in terms of presented principles. We wil conclude that none of the existing semantics satisfies the requirement. Finally we will present a semantics that satisfies all the requirements.

Rules

To ensure regular weekly seminar talks, there is one simple rule for the KR Group members: If no talk is scheduled, this obligation goes to that KR Group member who has done the most past talk.
