Patent ID: 8682032

Claim:
A method for classifying events through string pattern recognition, the method comprising: assigning text labels to image primitives in a time-ordered set of training images and to related time-ordered transactions in an associated training transaction log in a combined time-ordered training string of text labels as a function of image types, the assigning comprising labeling a transaction in the associated training transaction log with a transaction label, a training primitive image of a start of a transaction with a start image text label, a training primitive of an entry of a transaction into the log with an entry image text label, and a training primitive of a conclusion of a transaction with an ending image text label; discovering via a processor a plurality of positive subset string patterns representing true events from the combined time-ordered training string of text labels that are each repeated in at least two of the positive subset string patterns, start with a start image label, end with an ending image label, and comprise a single transaction primitive label; and defining a plurality of negative subset string patterns by removing the single transaction primitive label from each of the plurality of positive subset string patterns.
