Subject: 2nd Workshop on Linking Models of Lexical, Sentential and Discourse-level Semantics

 
Full Title: 2nd Workshop on Linking Models of Lexical, Sentential and Discourse-level Semantics 
Short Title: LSDSem 2017 

Date: 03-Apr-2017 - 04-Apr-2017
Location: Valencia, Spain 
Contact Person: Michael Roth
Meeting Email: mroth at coli.uni-saarland.de
Web Site: http://www.coli.uni-saarland.de/~mroth/LSDSem/ 

Linguistic Field(s): Computational Linguistics; Discourse Analysis; Lexicography; Semantics 

Call Deadline: 16-Jan-2017 

Meeting Description:

Past work on computational models of semantics is often fragmented across
different levels of semantics, with developments in one level disconnected
from the others. LSDSem aims to provide a venue for researchers from lexical,
sentential and discourse-level semantics to interact, encouraging the
development of models of natural language understanding that use multiple
levels of semantics.

LSDSem 2017 will continue the theme of linking lexical, sentential, and
discourse-level semantics, and submissions describing efforts in these areas
are strongly encouraged. This includes core research on joint or ensemble
models, new evaluations to measure different levels semantics, and
applications that require more than one level of semantics to solve.

In addition, this year we have an additional focus on the comprehensive
understanding of narrative structure in language. Recently a range of tasks
have been proposed in the area of learning and applying commonsense/procedural
knowledge. Such tasks include, for example, learning prototypical event
sequences and event participants, modelling the plot structure of novels, and
resolving anaphora in Winograd schemas. Knowledge on the level of scripts and
narratives is not only useful to represent stories, recipes, and how-to
instructions in a meaningful way, but can also be applied in downstream
applications. Examples include, in particular, applications that require
reasoning on the document level.

With respect to the area of focus, LSDSem 2017 will include a shared task (see
below) and a discussion on challenges related to new datasets, evaluation
techniques, and models for richer semantics.

Call for Participation: 

Shared Task:

Our shared task is the Story Cloze Test
(https://competitions.codalab.org/competitions/15333). This test is one of the
recent proposed frameworks on learning common sense/procedural knowledge,
which introduces a new evaluation for story understanding and script learning.
In this test the system reads a four-sentence story along with two alternative
endings, then it is tasked with choosing the correct ending to the story.
Story Cloze Test requires systems to link various levels of semantics to
common sense knowledge for successful narrative understanding. More details
will be available at: http://cs.rochester.edu/nlp/rocstories/.

Long and Short Papers:

We solicit long (8 page) and short (4 page) papers on topics that include:

- Approaches for enriching models of lexical and sentence semantics with
discourse information
- Joint models of lexical, sentential and discourse semantics (or pairs
thereof)
- Evaluation methods and analysis of system performance that emphasize
different levels of semantics
- Applications, such as summarization, text generation and question answering,
developed based on multiple layers of semantic information
- Models for narrative structure, script learning, and applying common sense
knowledge for inference
- Meaning representations for procedural texts such as technical instructions
and recipes

System Description Papers:

We invite system description papers from participants in the shared task. The
papers should describe the approach and results. We also encourage papers
providing insights on negative results on the task.

All submissions must follow the EACL 2017 formatting instructions described at
http://eacl2017.org/index.php/calls/call-for-papers.

Submission instructions will be sent out with the next call for papers (around
December 9).
