NP4E corpus

This is a coreferentially annotated corpus of newswire texts, extracted from the Reuters corpus (see WC0163). 5 clusters of texts have been selected on the topic of terrorism (55,000 words) : Bukavu bombing in Zaire, Peru hostages, Tajikistan hostages, Israel suicide bomb and China-Taiwan hijack.

The NP4E corpus is annotated for NP (noun phrase) coreference following specific guidelines. It is available in xml and in the MMAX format.

A small part of this corpus (12,500 words) is also annotated for event coreference. Events and arguments associated with each event are labelled in xml.

This corpus can be used for further studies on coreference annotation, cross-document coreference, anaphora resolution ...
