Spanish TimeBank 1.0 was developed by researchers at Barcelona
Media and consists of Spanish texts in the AnCora
corpus annotated with temporal and event information according to the TimeML
TimeML (Pusteyovsky, et al., 2005) is a schema for annotating eventualities
and time expressions in natural language as well as the temporal relations among
them, thus facilitating the task of extraction, representation and exchange
of temporal information. Spanish Timebank 1.0 is annotated in three levels,
marking events, time expressions and event metadata. The TimeML annotation scheme
was tailored for the specifics of the Spanish language. Temporal relations in
Spanish present distinctions of verbal mood (e.g., indicative, subjunctive,
conditional, etc.) and grammatical aspect (e.g., imperfective) which are absent
in English. Spanish TimeBank 1.0 joins the family of TimeBank annotated corpora
which includes languages such as English, Italian, French, Korean and Chinese.
Through their common layer of annotation, these corpora provide resources useful
for multilingual temporal extraction and processing, such as multilingual text
entailment, opinion mining or question answering. Spanish Timebank 1.0 is the
Spanish language complement to Catalan
Timebank 1.0 LDC2012T10.
LDC has released other corpora incorporating TimeBank annotation:
TimeBank 1.2 LDC2006T08, FactBank
1.0 LDC2009T23 and ModeS
TimeBank 1.0 LDC2012T01.
Spanish TimeBank 1.0 contains stand-off annotations for 210 documents with
over 75,800 tokens (including punctuation marks) and 68,000 tokens (excluding
punctuation). The source documents are news stories and fiction from the AnCora
The AnCora corpus is the largest multilayer annotated corpus of Spanish and
Catalan. AnCora contains 400,000 words in Spanish and 275,000 words in Catalan.
The AnCora documents are annotated on many linguistic levels including stucture,
syntax, dependencies, semantics and pragmatics. That information is not included
in this release, but it can be mapped to the present annotations. The data contained
in the AnCora corpus has been used in several international natural language
processing evaluations such as CoNLL-2006,
CoNLL-2007 and SemEval-2007.
The corpus is freely available from the Centre
de Llenguatge i Computació (CLiC).
