shared task

Word sense disambiguation (WSD) has been a core research problem in computational linguistics since the very inception of the field. In recent years, there has been considerable interest in using lexical substitution as an extrinsic evaluation of WSD systems. This has led to a number of mono- and crosslingual evaluation competitions at SemEval and EVALITA. We now invite all researchers and industry professionals to participate in GermEval 2015: LexSub, the first lexical substitution task for the German language.

task in natural language processing. This year's shared task will be grammatical

SHARED TASK DESCRIPTION

We are excited to organize the first shared task in Native Language Identification (NLI) which is the task of identifying the native language (L1) of a writer based solely on a sample of their writing. The task is framed as a classification problem where the set of L1s is known a priori. Most work has focused on identifying the native language of writers learning English as a second language. This problem has been growing in popularity and has motivated several ACL, NAACL and EMNLP papers, as well as a master's and doctorate thesis.

GENERATION CHALLENGES 2012
--------------------------

To be held in conjunction with INLG 2012, 30 May-01 June 2012, Starved Rock, IL, USA.

Over the past five years, there has been a lot of activity in
connection with shared tasks in Natural Language Generation (NLG).
Six separate sets of shared tasks each with its own data and team of
organisers have so far been run: TUNA (Gatt et al.), GREC (Belz et
al.), GIVE (Koller et al.), QG (Rus et al.), HOO (Dale and Kilgarriff)

*SEM Shared Task 2012: Call for Proposals

ACL special interest groups SIGLEX and SIGSEM invites proposals for the *SEM Shared Task 2012.

GIVE-2.5: Last Call for Participation/System Submissions
http://www.give-challenge.org/research/

Part of Generation Challenges 2011
Endorsed by SIGGEN and SIGSEM

We invite you to participate in the next edition of the Challenges on Generating Instructions in Virtual Environments (GIVE) by submitting an NLG system for the GIVE scenario. In this scenario, a human user performs a "treasure hunt" task in a virtual 3D environment. The NLG system's job is to generate, in real time, a sequence of natural-language instructions that will help the user perform this task.
