<p class="MsoPlainText"><span lang="EN-US">We invite participants to a new SemEval-2012 task: Cross-lingual Textual Entailment (CLTE) for Content Synchronization.

<p class="MsoPlainText"><span lang="EN-US">Given a pair of topically related text fragments (T1 and T2) in different languages, the CLTE task consists of automatically annotating it with one of the following entailment judgments:
<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">- Bidirectional (T1 entails T2; T2 entails T1)<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">- Forward (T1 entails T2; T2 does not entail T1)
<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">- Backward (T1 does not entail T2; T2 entails T1)<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">- No Entailment (T1 does not entail T2; T2 does not entail T1)<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">Datasets are available for the following language combinations:<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">- Spanish/English <o:p></o:p></span></p>

<p class="MsoPlainText"><span lang="EN-US">The CLTE task addresses textual entailment recognition under a new dimension (cross-linguality), and within a new challenging application scenario (content synchronization).<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">Cross-linguality represents a dimension of the TE recognition problem that so far has been only partially investigated. The great potential of integrating monolingual TE recognition components into NLP architectures
has been reported in several areas, including question answering, information retrieval, information extraction, and document summarization. However, mainly due to the absence of CLTE recognition components, similar improvements have not been achieved yet
in any cross-lingual application. The CLTE task aims at prompting research to fill this gap.<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">Content synchronization represents a challenging application scenario to test the capabilities of advanced NLP systems. Given two documents about the same topic written in different languages (e.g. Wikipedia articles),
the task consists of automatically detecting and resolving differences in the information they provide, in order to produce aligned, mutually enriched versions of the two documents. Towards this ambitious objective, a crucial requirement is to identify the
information in one page that is equivalent or novel (more informative) with respect to the content of the other. The task can be naturally cast as an entailment-related problem, where bidirectional and unidirectional entailment judgments for two text fragments
are respectively mapped into judgments about semantic equivalence and novelty. Alternatively, the task can be seen as a Machine Translation evaluation problem, where judgments about semantic equivalence and novelty relate to the possibility that one text fragment
is the full or partial translation of the other.<o:p></o:p></span></p>
