LexSem+Logics 2016

(Third Workshop on Logics and Ontologies) (First Workshop on Lexical Semantics for Lesser-Resourced Languages)

Aims and Scope

Lexical semantics continues to play an important role in driving research directions in NLP, with the recognition and understanding of context becoming increasingly important in delivering successful outcomes in NLP tasks. Areas such as word sense and named entity disambiguation, coreference resolution and the creation and maintenance of dictionaries, annotated corpora and resources have been the cornerstones of lexical semantics research and produced a wealth of contextual information that NLP processes can exploit. New efforts both to link and construct from scratch such information – as Linked Open Data or by way of formal tools coming from logic, ontologies and automated reasoning – have increased the interoperability and accessibility of resources for lexical and computational semantics, even in those languages for which they have previously been limited.

LexSem+Logics 2016 combines the 1st Workshop on Lexical Semantics for Lesser-Resources Languages and the 3rd Workshop on Logics and Ontologies. Its aim is to bring together researchers interested in a range of topics across these two areas – advances in the recognition and disambiguation of lexical semantic units, exploiting new or existing tools for resolving lexical semantic issues in NLP, formal approaches on dealing with semantics, the combination of logical and statistical methods for acquiring and using ontologies for computational semantics, and many more. While the workshop will be co-located with PROPOR2016 and papers focusing on Portuguese are of course of interest, we encourage submissions that focus on any language for which lexical resources have traditionally been scarce.

LexSem+Logics 2016 is endorsed by SIGLEX – ACL Special Interest Group on the Lexicon.

Topics of Interest

The workshop invites papers on a range of topics, including (but not limited to):

  • recognition, classification and disambiguation of lexical semantic units
  • extracting knowledge using lexical semantic units
  • ontologies, datasets and representations of knowledge
  • logic for semantics of lexical semantic units, sentences, discourse and dialog
  • formal tools in ontology creation, re-use and evaluation
  • formal tools in textual inference, such as logics for natural language inference
  • formal approaches to unifying data-driven and declarative approaches to semantics
  • (open) linking of ontologies, resources and datasets
Papers and Publication

Papers of up to 8 pages in length (+2 pages for references) are invited. Papers should follow the same template as the main PROPOR conference (found here) and can be submitted through the workshop’s EasyChair submissions page.

The proceedings will be made available on this page by the date of the workshop itself, as well as on a yet-to-be-decided online open-access publication repository. Hard copies will also be provided to attendees.

Important Dates

  • 16th May – notification of authors
  • 27th May – camera-ready deadline
  • 13th July – workshop
