Abstract

Embodiments of the invention relate to an improved electronic discovery. More specifically, embodiments relate to managing the process for creating search term sets to be applied to electronic data sets associated with a case in an electronic discovery system. A search term management application is provided that allows for multiple users to work collaboratively to define the final search term set that is subsequently applied to the corpus of electronic data for the case. In addition, the application provides for tracking the overall search term creation process. In addition, embodiments provide for a search term hit count engine that is configured to determine search term hit counts for a portion of a corpus of data, such that the determined search term hit count may be predictive of the volume of data needed to review.

(4) store, in the case profile, modifications to the search term set including modification tracking data wherein the modification tracking data includes type of search term modification, details of the search term modification, originator of the search term modification and date of search term modification and wherein type of modification includes one of adding a search term to the search term set, deleting a search term from the search term set or altering a search term in the search term set, and

(5) receive, via the search term user interface, a third input, wherein the third input finalizes the search term set; and

a search term administrator application stored in the memory, executable by the processor and configured to;

(1) apply the search term set to a portion of the corpus electronic data to determine, in the portion of the corpus of electronic data (1) an overall quantity of search term hits, (2) a quantity of search term hits for each search term in the search term set, (3) an overall quantity of search term hit counts per data type and (4) a quantity of search term hits for each search term in the search term set per data type, wherein the data types include electronic mail data and electronic file data;

(2) predict, for an entirety of the corpus of electronic data based on results of applying the search term set to the portion of electronic data, the volume of the corpus of electronic data required to be reviewed; and
