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 14):
The computer-implemented method of  claim 1 , wherein extracting the first salient text feature comprises extracting a first numerical expression using a regular expression, wherein extracting the second salient text feature comprises extracting a second numerical expression using a regular expression, and wherein the event similarity score is determined based on the first numerical expression and the second numerical expression.
