Building a Cross-document Event-Event Relation Corpus
نویسندگان
چکیده
We propose a new task of extracting eventevent relations across documents. We present our efforts at designing an annotation schema and building a corpus for this task. Our schema includes five main types of relations: Inheritance, Expansion, Contingency, Comparison and Temporality, along with 21 subtypes. We also lay out the main challenges based on detailed inter-annotator disagreement and error analysis. We hope these resources can serve as a benchmark to encourage research on this new problem.

GPLSIUA: Combining Temporal Information and Topic Modeling for Cross-Document Event Ordering
Building unified timelines from a collection of written news articles requires cross-document event coreference resolution and temporal relation extraction. In this paper we present an approach event coreference resolution according to: a) similar temporal information, and b) similar semantic arguments. Temporal information is detected using an automatic temporal information system (TIPSem), wh...

In this paper, we present the NewsReader MEANTIME corpus, a semantically annotated corpus of Wikinews articles. The corpus consists of 480 news articles, i.e. 120 English news articles and their translations in Spanish, Italian, and Dutch. MEANTIME contains annotations at different levels. The document-level annotation includes markables (e.g. entity mentions, event mentions, time expressions, ...

This paper describes the process of building a newspaper corpus annotated with events described in specific documents. The main difference to the corpora built as part of the TDT initiative is that documents are not annotated by topics, but by specific events they describe. Additionally, documents are gathered from sixteen sources and all documents in the corpus are annotated with the correspon...

متن کاملBuilding Patterns for Biomedical Event Extraction
Generally, Event Extraction is to identify any instance of a particular class of events in a natural language text, to extract the relevant arguments of the event, and to represent the extracted information into a structured form.1Let us define Event on the binary relation between two entities for special event verbs which are predefined by biologists. Here, Entity means biomedical entities suc...
