=========================================================================                           CALL FOR PAPERS     PLP 2021: The Eighth Workshop on Probabilistic Logic Programming                   http://stoics.org.uk/plp/plp2021 =========================================================================    A workshop of 37th International Conference on Logic Programming                        September 20-27, 2021                      (the event will be virtual) ========================================================================= ** Deadline for submissions: August 1st 2021 Overview ******** Probabilistic logic programming (PLP) approaches have received much attention in this century. They address the need to reason about relational domains under uncertainty arising in a variety of application domains, such as bioinformatics, the semantic web, robotics, and many more. Developments in PLP include new languages that combine logic programming with probability theory, as well as algorithms that operate over programs in these formalisms. The workshop encompasses all aspects of combining logic, algorithms, programming and probability. PLP is part of a wider current interest in probabilistic programming. By promoting probabilities as explicit programming constructs, inference, parameter estimation and learning algorithms can be ran over programs which represent highly structured probability spaces. Due to logic programming's strong theoretical underpinnings, PLP is one of the more disciplined areas of probabilistic programming. It builds upon and benefits from the large body of existing work in logic programming, both in semantics and implementation, but also presents new challenges to the field. PLP reasoning often requires the evaluation of large number of possible states before any answers can be produced thus breaking the sequential search model of traditional logic programs. While PLP has already contributed a number of formalisms, systems and well understood and established results in: parameter estimation, tabling, marginal probabilities and Bayesian learning, many questions remain open in this exciting, expanding field in the intersection of AI, machine learning and statistics. This workshop provides a forum for the exchange of ideas, presentation of results and preliminary work, in the following areas * probabilistic logic programming formalisms * parameter estimation * statistical inference * implementations * structure learning * reasoning with uncertainty * constraint store approaches * stochastic and randomised algorithms * probabilistic knowledge representation and reasoning * constraints in statistical inference * applications, such as * * bioinformatics * * semantic web * * robotics * probabilistic graphical models * Bayesian learning * tabling for learning and stochastic inference * MCMC * stochastic search * labelled logic programs * integration of statistical software This list is by no means exhaustive. Purpose ******** After seven successful editions of this workshop, the eighth edition of PLP will be held at the ICLP virtual conference organised by the University of Porto. We hope that this encourages further collaboration between researchers in PLP and researchers working in other areas of ICLP. Submissions *********** Submissions will be managed via EasyChair (to be announced). Contributions should be prepared in the LNCS style. A mixture of papers are sought including: new results; work in progress; and technical summaries of recent substantial contributions.  Papers presenting new results should be 6-15 pages in length. Work in progress and technical summaries can be shorter (2-5 pages). The workshop proceedings will clearly indicate the type of each paper. At least one author of each accepted paper will be required to attend the workshop to present the contribution. Publication *********** Informal proceedings will be made available electronically to attendees and submitted to CEUR Workshop Proceedings repository (http://ceur-ws.org/). The proceedings will consist of clearly marked sections corresponding to the different types of submissions accepted. Deadlines ********* Papers due: August 1st, 2021 Notification to authors: September 1st, 2021 Camera ready version due: September 10th, 2021 Workshop date: September 20-27, 2021 (all dates are AoE) Invited Speaker(s) ****************** TBA Programme Committee Chairs ************************** Rafael Penaloza (University of Milano-Bicocca, Italy) Felix Weitkämper (LMU München, Germany) Programme Committee ******************* TBA =========================================================================
