Abstract: Embodiments of the invention relate to systems, methods, and computer program products for improved electronic discovery. More specifically, embodiments relate to computer program products for targeted document review assignments by determining concept-related data groupings within the overall corpus of data associated with a case and assembling the targeted document review assignments based on the concept-related data groupings. As such, document reviewers are presented with assignments that have highly conceptually-related documents, which results in further efficiency in the review process.
