1. A method for data correlation comprising the steps of: providing a first correlation between a first information artifact collection and a second information artifact collection; extracting at least a first feature from a second information artifact in said first information artifact collection and at least a first feature from a second information artifact in said second information artifact collection, wherein said extraction step comprises the steps of: (i) identifying at least a first lexical category in a second information artifact in said first information artifact collection; (ii) identifying at least a first phrase in said information artifact; (iii) normalizing at least a first term in said information artifact; (iv) removing all features except for nouns, verbs, and phrases from said information artifact; and (v) removing each feature that occurs only once in said information artifact; selecting at least said first extracted features from said first and second information artifact collections; creating a correlation index between said selected features, wherein said creating step comprises the steps of: (i) pairing at least a first feature extracted from said second information artifact in said first information artifact collection with at least a first feature extracted from a second information artifact in said second information artifact collection; and (ii) calculating a correlation score between said paired features; extracting at least a first feature from a third information artifact in said first information artifact collection; applying said correlation index to said first feature extracted from said third information artifact; and computing a correlation score between said first feature extracted from said third information artifact and at least a first feature from one or more information artifacts in said second information artifact collection.
7. The method according to claim 1 , wherein said selecting step further comprises the step of: filtering said extracted features using a first filter.
