Call for Contributions Workshop on Trends, Extensions, Applications and Semantics of Logic Programming (TEASE-LP 2020) Dublin, Ireland, 25 April 2020 (co-located with ETAPS 2020) www.coalg.org/tease-lp Logic programming is a framework for expressing programs, propositions and relations as Horn clause theories, with the purpose of performing automatic inference in these theories. Horn clause theories are famous for their well-understood declarative semantics, in which models of logic programs are given inductively or coinductively. At the same time, Horn clauses give rise to efficient inference procedures, usually involving resolution. Logic programming found applications in type inference, verification, and AI. While logic programming was originally conceived for describing simple facts, it was extended to account for much more complex theories. This includes higher-order theories, inductive and coinductive data, and stochastic/probabilistic theories. The aim of this workshop is to bring together researchers that work on extensions of logic programming and inference methods, and to foster an exchange of methods and applications that have emerged in different communities. Topics --------------------------- The central idea of this workshop is to discuss the theory of logic programming and associated topics that have as well the goal to automatically infer knowledge and proofs. Our intention is to bring together researchers that work on the numerous topics that contribute to automatic proof inference and foster an exchange that may lead to advances in the theory of logic programming. Topics of interest include, but are not limited to, the following: * Proof theory (e.g. focalised and uniform proofs), * Logic programming beyond the classical Horn clause theories (e.g. coinduction, higher-order Horn clauses, probabilities, categorical logic, inductive LP), * Extensions of logic programming (e.g. DataLog, description logic, relational programming), * Advanced implementations (e.g. λProlog, ELPI, miniKanren), * Type theory (e.g. polarised λ-calculus, proofs-as-programs, types for logic programming), * Semantics (e.g. classical, categorical, algebraic, coalgebraic) , and * Applications. Venue and Event --------------------------- TEASE-LP 2020 will be held in Dublin, Ireland, co-located with ETAPS 2020 on 25 April 2020.

Submissions should be abstracts of at most two pages in EPTCS style (http://style.eptcs.org/) and will be only be published in the informal pre-proceedings and on the website of the workshop. Post-proceedings volume may be solicited by the PC, based on the quality of contributions. Contributions should be submitted via the Easychair system: https://easychair.org/my/conference?conf=teaselp2020 All contributions will be refereed by the programme committee and it is expected that at least one of the authors will be present during the workshop.
