Abstract
First and second screenshot images are obtained from a monitoring application provided on a first computing device. Each screenshot image comprises a plurality of content portions displayed by a communication application on the first computing device, and content boxing is performed to calculate a plurality of content boxes for the plurality of content portions. Each content box is classified as containing textual communication content or image communication content. Textual communications are extracted via Optical Character Recognition (OCR) and object identifiers are extracted from the image communications via image recognition. At least one shared content box present in both the first and second screenshot images is identified and used to temporally align the extracted textual communications. The temporally aligned textual communications are condensed into a textual communication sequence.
