Abstract
Systems and methods are provided for indexing a document according to identified events. An event-based indexing system includes a source interface configured to receive the document from an associated data source and format the document for processing and an indexer configured to extract event mentions from the document, with a given event mention comprising a verb and at least one of a subject and an object of the verb. A document index is configured to store the extracted event mentions such that a given document from an associated document corpus can be retrieved according to its associated event mentions
