This volume contains the Regular Papers, Technical Communicationsand the Doctoral Consortium papers of the 35th International Conference on Log ic Programming (ICLP 2019), held in Las Cruces, New Mexico, USA, from September 20-25, 2019. Since the first conference held in Marseille in 1982, ICLP has been the premier international event for presenting research in logic programming. Cont ributions are sought in all areas of logic programming, including but not restricted to: Foundations: Semantics, Formalisms, Nonmonotonic reasoning, Knowledge repre sen-tation.

Her contributions in this endeavor include serving as PI of the SAIC Evaluation and Knowledge Infrastructure Team for the DARPA Machine Reading Program, which focused on developing methods to extract formal knowledge from free text; and PI of TAILCM, an IARPA sponsored seedling that has investigated the feasibility of translating regulatory text written in natural language to rules in formal logic programming languages. Before joining SAIC, Dr. Morgensten was Research Staff Member at the IBM T. J. Watson Research Center in Hawthorne, NY where she developed leading technologies in the areas of decision support, knowledge management, customer relationship management, business rules, and the semantic web. Dr. Morgenstern has served as technical lead for developing and deploying applications for Fortune-500 companies in a diversity of industries, including medical insurance, banking, insurance, telephony, software sales, and business continuity. Her patents have won several IBM awards due to their value to industry. Dr. Morgenstern has been on the editorial boards of Journal of Artificial Intelligence Research, Annals of Mathematics and Artificial Intelligence, and Electronic Transactions of Artificial Intelligence.

Welcome to the Twenty-Seventh AAAI Conference on Artificial Intelligence, AAAI-13! As can be seen in these proceedings, AI's scope and influence continue to grow. This year, we received 827 submissions across a variety of tracks, allowing us to put together a diverse and exciting technical program featuring the field's top research. The AAAI-13 program seeks to capture the diversity of this important field. The main technical program features four special tracks -- AI and the Web, Cognitive Systems, Computational Sustainability, and AI and Robotics -- which highlight specialized areas of the field.

Candidate papers for the AAAI-13 awards were selected based on overall ratings and nominations by the PC and Senior PC. A committee composed of the Program Cochairs and several Associate Chairs and Senior Program Committee Members reviewed all candidate papers and selected the winning papers. This year, two papers were selected for their exceptional quality in all review categories. In addition, four papers were selected for honorable mention, based on their overall high quality and particularly outstanding contributions in specific areas. Each year, AAAI recognizes several outstanding program committee and senior program committee members.
