Semantic Textual Similarity (STS) SemEval 2013 - Task 6


Following the success of the 2012 task on STS (Agirre et al.
2012), with 35 teams and 88 runs, we solicit participation in the
second STS task, which will held at SemEval 2013, co-located with
the *SEM and NAACL-2013 conferences.

STS in 2013

Participants will submit systems that examine the degree of
semantic equivalence between two sentences. The goal of the STS
task is to create a unified framework for the evaluation of
semantic textual similarity modules and to characterize their
impact on NLP applications. We particularly encourage submissions
from the lexical semantics, summarization, machine translation
evaluation metric, and textual entailment communities.

The task will follow a similar design as last year, but instead
of providing train/test data from the same datasets, we will
provide all the 2012 data as training data, and the test data
will be drawn from related but different datasets. This setting
is more realistic, and the teams which prefer to train/test on
the same datasets can perfomr experiments using the 2012 data.

The task will thus comprise all the 2012 data plus the following

    New test data similar to the datasets used last year
    (Paraphrase, SMT evaluation, gloss pairs). The SMT evaluation
    data will include data from HyTER graphs. A dataset on
    typed-similarity between semi-structured items, comprising
    both train and test data. An open source baseline, comprising
    a pipeline to combine STS systems and components. An new
    measure for evaluation.

detailed task description.
