Introduction to the papers presented at the 2013 FLAIRS Conference Special Track on Artificial Intelligence, Cognitive Semantic, Computational Linguistics, and Logic.

Propositional attitudes in noncompositional logic are analysed from the view point of integration of their epistemic and deontic components. A new logical calculus for propositional attitudes inspired by possibility theory, a noncompositional version of fuzzy logic is proposed.

Traditionally, the study of computational linguistics (CL) has been performed by computer scientists specializing in the application of computers to the processing of a natural language. Today, computational linguists often work as members of interdisciplinary teams that include linguists (specifically trained in linguistics), language experts (persons with some level of ability in the languages relevant to a given project), and computer scientists. CL must become more connected to the cognitive sciences through the development of cognitive semantic theories. CL is connected to AI through the development of methods and algorithms for all aspects of language analysis and their computer implementation. We can see language analysis divided into two parts: theoretical analysis and application.
