Information Affinity: A New Similarity Measure for Possibilistic Uncertain Information
Abstract. This paper addresses the issue of measuring similarity between pieces of uncertain information in the framework of possibility theory. In a first part, natural properties...

Approaches to Constructing a Stratified Merged Knowledge Base
Many merging operators have been proposed to merge either flat or stratified knowledge bases. The result of merging by such an operator is a flat base (or a set of models of the me...

Conflict Analysis and Merging Operators Selection in Possibility Theory
In possibility theory, the degree of inconsistency is commonly used to measure the level of conflict in information from multiple sources after merging, especially conjunctive merg...

Logical Refinements of Church's Problem
Abstract. Church's Problem (1962) asks for the construction of a procedure which, given a logical specification on sequence pairs, realizes for any input sequence X an output...

MSO on the Infinite Binary Tree: Choice and Order
We give a new proof showing that it is not possible to define in monadic second-order logic (MSO) a choice function on the infinite binary tree. This result was first obtained by G...

Lambda Theories of Effective Lambda Models
Abstract. A longstanding open problem is whether there exists a nonsyntactical model of the untyped -calculus whose theory is exactly the least -theory . In this paper we investiga...

Interactions between Time and Knowledge in a First-order Logic for Multi-Agent Systems
We investigate a class of first-order temporal epistemic logics for the specification of multi-agent systems. We consider well-known properties of multi-agent systems including ...

Improving Query Answering over DL-Lite Ontologies
The DL-Lite family of Description Logics has been designed with the specific goal of allowing for answering complex queries (in particular, conjunctive queries) over ontologies w...

On the Complexity of Axiom Pinpointing in the EL Family of Description Logics
We investigate the computational complexity of axiom pinpointing, which is the task of finding minimal subsets of a Description Logic knowledge base that have a given consequence...
