Meeting Description:

GermEval 2015: LexSub
(German Lexical Substitution Shared Task)
29 September 2015 at GSCL 2015, Essen, Germany
https://sites.google.com/site/germeval2015

Introduction:

We invite all researchers and industry professionals to participate in GermEval 2015: LexSub, the first lexical substitution task for the German language.  The task is associated with the GSCL 2015 conference in Essen, and will take place as a workshop there on 29 September 2015.

Task Description:

Lexical substitution is the task of identifying an appropriate substitute for a target word in a given context. For example, in the sentence ''She's a bright kid who excels academically,'' an appropriate substitute for ''bright'' might be ''smart'', whereas an inappropriate one would be ''glowing''. Automatically identifying substitution candidates, and selecting those which best match the context, requires intelligent application of lexical-semantic knowledge and word sense disambiguation techniques. However, unlike traditional WSD tasks, lexical substitution does not mandate the use of any particular sense inventory.

The data for the GermEval 2015: LexSub task is described by Cholakov et al. in ''Lexical substitution dataset for German'' (Proc. LREC, 2014). All together it consists of 2040 sentences from the German Wikipedia, each containing a target word and a list of substitutions proposed by human annotators.

Participants need not rely on any particular language resources, but if they wish they can employ the sense-linked lexical-semantic resource UBY and JoBimText distributional semantics models. UBY also provides an interface to GermaNet. Industrial users will be eligible to a special GermaNet licence to be obtained from Eberhard-Karls Universität Tübingen. Please refer to our web pages on how to obtain the data sets and resources.

Systems' performance will be measured by comparing their substitutes against those selected by the human annotators. The organizers will provide a scoring system and the output of some baseline systems.

Location:

University of Duisburg-Essen, Campus Essen, Germany

2nd Call for Participation:

Practical Information:

- 23 January 2015: Availability of training data
- 1 July 2015: Availability of test data
- 15 July 2015: Deadline for initial submission of papers and results
- 1 August 2015: Notification of acceptance and shared task results
- 15 August 2015: Deadline for camera-ready papers
- 30 September–2 October 2015: GSCL 2015

Submissions will consist of a file providing the substitutions for each instance of the target data and a paper of up to four pages (including references) describing the approach and analyzing the performance. Papers should follow the GSCL 2015 style guide, and will be reviewed and published in an online volume of workshop proceedings. (We may ask participants to peer-review other submissions.) Participants are expected to present summaries of their systems at the GermEval 2015: LexSub workshop at GSCL 2015.
