Abstract:
A system and method for event matching by analysis of text characteristics are presented. A document collection comprising documents is acquired. One or more document subsets of the document collection each comprising one or more documents potentially describing identical events are identified based on certain structured metadata fields of the documents. Salient text features are extracted from the documents in the document collection. An event similarity score for pairs of documents in the document collection is generated by comparing the text features extracted from the documents. A common event document list comprising sets of documents in the document collection whose event similarity scores with each other are above a similarity threshold is generated.

Claim (Index 1):
A computer-implemented method for event matching, the computer-implemented method comprising:\n acquiring a plurality of documents, wherein each document of the plurality of documents comprises respective metadata that is indicative of an event attribute; identifying a document subset comprising multiple documents of the plurality of documents using the respective metadata for each document of the multiple documents; extracting a first salient text feature from a first document of the multiple documents and a second salient text feature from a second document of the multiple documents; determining, based on a comparison between the first salient text feature and the second salient text feature, an event similarity score for the first document and the second document; and upon determining that the event similarity score satisfies a threshold condition, including the first document and the second document as a pair of documents in a common event document list, wherein the common event document list identifies pairs of documents whose respective event similarity scores satisfy the threshold condition; and providing, for display by a presentation module, the common event document list.
