OneIE: A Joint Neural Model for Information Extraction with Global Features
Please email Ying Lin if you experience any technical issues using our software or need further information.
Given a sentence, our OneIE framework aims to extract an information network representation, where entity mentions and event triggers are represented as nodes, and relations and event-argument links are represented as edges. In other words, we jointly perform entity, relation, and event extraction within a unified framework.
- Entity Extraction aims to identify entity mentions in text and classify them into pre-defined entity types. For example, "Kashmir region" should be recognized as a Location (loc) mention. A mention can be a name, nominal, or pronoun.
- Relation Extraction is the task of assigning a relation type to a pair of entity mentions. For example, there is a part-whole relation between "Kashmir region" and "India".
- Event Extraction entails identifying event triggers (the words or phrases that most clearly express event occurrences) and their arguments (the words or phrases for participants in those events) in unstructured texts and classifying these phrases, respectively, for their types and roles. An argument can be an entity, time expression, or value (e.g., money, job-title, crime). For example, the word "injured" triggers an injure event and "300" plays as the victim argument.
