*** IULP 2019 *** 3rd International Workshop on User-Oriented Logic Paradigms June 3 or 4, 2019

https://iulp2019.uni-leipzig.de

Collocated with the 15th International Conference on Logic Programming and Nonmonotonic Reasoning (LPNMR 2019) Philadelphia, USA June 4 - 6, 2019 ---------------

Since the emergence of logic reasoning paradigms, such as logic programming, argumentation, and other non-monotonic reasoning formalisms, a lot of theoretical work has been done, for example with respect to different semantics and their properties. More recently, implementations and IDEs emerged which have been used for various problem-solving applications. However, user-friendliness is still an issue for both experts and non-experts working with logic paradigms; for example experts benefit from features like debugging and heuristic tuning, non-experts from educational material, explanations, and intuitive visualisations - all of which are ongoing topics of research.

The 3rd International Workshop of User-Oriented Logic Paradigms (IULP) focuses on discussing different aspects involved in making logic paradigms more user-friendly/oriented, where the "user" could be either an expert of the paradigm, or a non-expert who simply uses tools developed for the paradigm in some application. IULP aims to bring together researchers working on different logic paradigms, such as answer set programming, constraint logic programming, probabilistic logic programming, abductive logic programming, inductive logic programming, argumentation, principles of teaching etc., as user- friendliness is an important topic in all of these areas.

IULP aims to provide an international forum for researchers in the AI, KR, and applied sciences community to discuss and present advances in theories, formalisms, and applications to deliver the mature and well-defined methods of logic paradigms to a wider audience.

We solicit the submission of papers broadly centred on issues and research related to user-friendliness in logic paradigms and related fields. We welcome papers of either theoretical or practical nature, including work in progress.

IMPORTANT DATES [revised] --------------- * [Extended] Submission deadline: Sun, April 28th 2019 * [Extended] Notification to authors: Mon, May 12th 2019 * [Extended] Camera-ready version due: Mon, May 26th 2019 * Workshop date: June 3 or 4, 2019

TOPICS --------------- Topics of interest include (but are not limited to): * IDEs * debugging * explanations * visualisation * best practice * modularity * usage of natural language * heuristic tuning * LP education * language extensions * transparency * algorithmic bias * credibility * accountable systems

SUBMISSIONS --------------- Papers must be formatted in Springer LNCS style (http://www.springer.com/lncs) and should not exceed 13 pages (excluding references and appendices). All submissions have to be written in English and submitted electronically as a PDF through easychair (https://easychair.org/conferences/?conf=iulp2019).

A short system demonstration version which should not exceed 6 pages (excluding references and appendices) can be submitted electronically too.

We encourage the submission of original research on all topics as well as relevant results that have been submitted or accepted elsewhere provided that the initial publication is mentioned in a footnote on the first page.

Note that authorship is not anonymous and that at least one author of each accepted paper is required to attend the workshop to present the contribution.

PROCEEDINGS --------------- There are no formal proceedings for IULP. The accepted papers will be published as a technical report and will be made available in the Computing Research Repository (CoRR).

The copyright of the papers lies with the authors and, as far as IULP is concerned, authors are free to submit their work to other conferences and workshops.

COMMITTEE --------------- Chairs: * Stefan Ellmauthaler (Leipzig University) * Christos Rodosthenous (Open University of Cyprus)
