Proceedings of the Software Demonstrations of the 15th Conference of the European Chapter of the Association for Computational Linguistics

Abstract

ii Introduction This volume contains the contributions accepted for Software Demonstrations at the EACL 2017 conference which takes place from 4th to 7th of April 2017 in Valencia, Spain.The Demonstrations program primary aim is to present the software systems and solutions related to all areas of computational linguistics and natural language processing. This program encourages the early exhibition of research prototypes, but also includes interesting mature systems.The number of submissions for software demonstrations exceeded, again, the number of available slots. This confronted us with the situation where we were forced to introduce a strict selection process. The selection process was completed following the predefined criteria of relevance for EACL 2017 conference: novelty, overall usability, and applicability to more than one linguistic level and to more than one computational linguistic field/task. We would like to thank the general chairs and the local organizers, without whom it would have been impossible to put together such a strong demonstrations program.We hope you will find this proceedings useful and that the software systems presented in this proceedings will inspire new ideas and approaches in your future work. AbstractIn semantic parsing, natural language questions map to meaning representation language (MRL) expressions over some fixed vocabulary of predicates. To do this reliably, one must guarantee that for a wide class of natural language questions (the so called semantically tractable questions), correct interpretations are always in the mapped set of possibilities. Here we demonstrate the system COVER which significantly clarifies, revises and extends the notion of semantic tractability. COVER is written in Python and uses NLTK.
