Abstract: Discovering second-order documents and latent custodians in an e-discovery system is provided. A list of first-order documents and document custodians within a base state of the e-discovery system are identified based on a plurality of terms corresponding to a meet and confer practice for a legal matter instance. The plurality of terms is masked within the first-order documents. The first-order documents having the plurality of terms masked are divided into groups. A list of second-order documents is generated from a group of documents. A list of second-order document custodians is generated based on corresponding custodian relationships to second-order documents. Finally, each second-order document custodian in the list of second-order document custodians that has a corresponding rank exceeding a defined rank threshold level is identified as an official document custodian in the e-discovery system.

Abstract: Processing a database query for sets of data includes assigning a unique identifier from an integer space to each entity within data and creating one or more sets of entities each pertaining to a corresponding entity within the data. A representation is then generated on disk for each set of entities, wherein each representation encompasses and is suited for a range of the unique identifiers of entities within a corresponding set and indicates a presence of an entity within that corresponding set. Finally, a query is processed based on the representation for each set of entities to retrieve data satisfying the query, wherein the representation provides a constant time for association and dissociation operations that are append-only operations with deferred merge and automatic filtering of deleted and duplicate entities at query time.

Abstract: According to one embodiment of the present invention, a system extends a content repository by creating an auxiliary data store outside of the content repository and storing auxiliary data in the auxiliary data store, wherein the auxiliary data is associated with a collection of documents in the content repository. The system stores version information for the auxiliary data store and records of operations against the auxiliary data store in a log in the repository. In response to receiving a request for an operation against the auxiliary data store, the system determines that the auxiliary data store and repository are consistent based on the version information and applies the operation against the auxiliary data store. Embodiments of the present invention further include a method and computer program product for extending a content repository data model in substantially the same manners described above.

Abstract: In searching electronic documents, prior to executing a query, a reviewer indicates whether a result set of the query will be dynamic or static. The query is then executed on the electronic documents to obtain an original result set, which is provided to the reviewer through a user interface. Upon determining that one or more changes to one or more of the electronic documents have occurred, and if the result set is static, then the original result set continues to be provided to the reviewer without re-executing the query. If the result set is dynamic, then the query is re-executed on the electronic documents to obtain an updated result set, and the updated result set is provided to the reviewer through the user interface. The original result set may be associated with a search session and/or may be a random sample of the electronic documents for an overview query.

Abstract: Provided are techniques for processing a query. A query including constraints for at least two vertically partitioned, inverted indexes is received. The constraints in the query are separated based on the vertically partitioned, inverted indexes. A document identifier iterator is obtained for each of the constraints, wherein each document identifier iterator is associated with a posting list, and wherein each posting list is ordered by document identifier order. A run-time join of the posting lists is performed to obtain a final result set.

Abstract: A method, apparatus and article of manufacture for analyzing data recorded in an audit log generated as part of an electronic discovery (e-Discovery) process in litigation is disclosed. In at least one embodiment of the present invention, a computer implemented method of analyzing data recorded in an audit log generated as part of an electronic discovery (e-Discovery) process in litigation is provided. The method comprises retrieving, on one or more computers, an audit log from a storage system accessible from the computer, the audit log comprising data regarding a chronological sequence of actions taken to produce case documents relevant in litigation. The data in the audit log is analyzed and a comprehensive overview of the electronic discovery process is compiled based on the analyzed data for presentation to a user.
