    Abstract: Systems and methods for protecting private data behind a privacy firewall are disclosed. A system for implementing a privacy firewall to determine and provide non-private information from private electronic data includes a data storage repository, a processing device, and a non-transitory, processor-readable storage medium. The storage medium includes programming instructions that, when executed, cause the processing device to analyze a corpus of private electronic data to identify a first one or more portions of the data having non-private information and a second one or more portions of the data having private information, tag the first one or more portions of the data as allowed for use, determine whether the second one or more portions of the data includes non-private elements, and if the second one or more portions of the data comprises non-private elements, extract the non-private elements and tag the non-private elements as information allowed for use.

  • Patent number: 10372717
    Abstract: Systems, methods, and computer-executable instructions for identifying a document are described. A method includes receiving a query from a graphical user interface having one or more concepts, normalizing a set of terms or concepts in the query to create a normalized query, comparing the normalized query to a set of document centric concept profiles associated with a set of documents in a corpus, where each document centric concept includes a plurality of concepts and at least one reference value for each concept, where the reference value is calculated by tabulating the number of times a document associated with one of the document centric concept profiles is cited by a citing instance for the concept, and surfacing a document from the corpus with the highest reference value for the concept.
