Thank you for your interest in TextGraphs-13!

Note that TextGraphs-14 will be held during COLING 2020 in Barcelona, Spain.

Workshop at EMNLP-IJCNLP 2019

Hong Kong

November 4, 2019

WORKSHOP DESCRIPTION

The workshops in the TextGraphs series have published and promoted the synergy between the field of Graph Theory and Natural Language Processing. Besides traditional NLP applications like word sense disambiguation and semantic role labeling, and information extraction graph-based solutions nowadays also target new web-scale applications like information propagation in social networks, rumor proliferation, e-reputation, language dynamics learning, and future events prediction, to name a few.

The (lucky!) thirteen edition of the TextGraphs workshop aims to extend the focus on (1) issues and solutions for large-scale graphs, such as those derived for web-scale knowledge acquisition or social networks and (2) graph-based and graph-supported machine learning and deep learning methods. We encourage the description of novel NLP problems or applications that have emerged in recent years, which can be addressed with existing and new graph-based methods. Furthermore, we also encourage research on applications of graph-based methods in the area of Semantic Web in order to link them to related NLP problems and applications.

VENUE

TextGraphs-13 will be collocated with the Conference on Empirical Methods in Natural Language Processing (EMNLP 2019) which will be held in Hong Kong on November 3–7, 2019.

The workshop will be situated on November 4, 2019 in room AWE 203+204+205, while the poster session will be organized in AWE Hall2A.

Poster session: the poster boards will be aluminium system panels of 1m width × 2.5m height (A0, portrait format).

CALL FOR PAPERS

TextGraphs-13 solicits both long and short paper submissions:

• a short paper has up to 4 pages of content plus unlimited references;
• a long paper has up to 8 pages of content plus unlimited references.

The formatting requirements are the same as in the EMNLP-IJCNLP 2019 conference that is hosting our workshop: https://www.emnlp-ijcnlp2019.org/calls/papers.

We accept submissions using the Softconf START conference management system: https://www.softconf.com/emnlp2019/ws-TextGraphs-2019.

IMPORTANT DATES

• Paper Submission Deadline: August 23, 2019
• Notification of Acceptance: September 16, 19 2019 **
• Camera-Ready Papers: September 30, 2019
• Workshop: November 3–4, 2019

SHARED TASK

We are organizing a shared task before the workshop. Our shared task on Explanation Regeneration asks participants to develop methods to reconstruct gold explanations for elementary science questions, using a new corpus of gold explanations that provides supervision and instrumentation for this multi-hop inference task. Each explanation is represented as an “explanation graph”, a set of atomic facts (between 1 and 16 per explanation, drawn from a knowledge base of 5,000 facts) that, together, form a detailed explanation for the reasoning required to answer and explain the resoning behind a question. Linking these facts to achieve strong performance at rebuilding the gold explanation graphs will require methods to perform multi-hop inference. The explanations include both core scientific facts as well as detailed world knowledge, allowing this task to appeal to those interested in both multi-hop reasoning and common-sense inference.
