Workshop at COLING 2020

Barcelona, Spain

September 14, 2020

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.

VENUE

TextGraphs-14 has been successfully accepted as a single-day event at COLING (https://coling2020.org) in Barcelona, Spain!

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.
