Information Retrieval for E-Discovery
Foundations and Trendsin Information Retrieval
E-discovery refers generally to the process by which one party (for
example, the plaintiff) is entitled to “discover” evidence in the form
of “electronically stored information” that is held by another party
(for example, the defendant), and that is relevant to some matter that
is the subject of civil litigation (that is, what is commonly called a
“lawsuit”). This survey describes the emergence of the field, identifies

this topic, and summarizes major open issues. -
Discovery of Related Terms in a corpus using Reflective Random Indexing
University of Maryland Land-grant university in College Park, Maryland
A significant challenge in electronic discovery is the ability to
retrieve relevant documents from a corpus of unstructured text
containing emails and other written forms of human-to-human
communications. For such tasks, recall suffers greatly since it is
difficult to anticipate all variations of a traditional keyword search
that an individual may employ to describe an event, entity or item
of interest. In these situations, being able to automatically identify

retrieve relevant documents from a corpus of unstructured text
containing emails and other written forms of human-to-human
communications. For such tasks, recall suffers greatly since it is
difficult to anticipate all variations of a traditional keyword search
that an individual may employ to describe an event, entity or item
of interest. In these situations, being able to automatically identify
conceptually related terms, with the goal of augmenting an initial
search, has significant value. We describe a methodology that
identifies related terms using a novel approach that utilizes
Reflective Random Indexing and present parameters that impact
its effectiveness in addressing information retrieval needs for the
TREC 2010 Enron corpus. -

Securing Block Storage Protocols
IETF
Secure block storage and storage discovery protocols running over IP (Internet Protocol) using IPsec and IKE (Internet Key Exchange). Threat models and security protocols are developed for iSCSI (Internet Protocol Small Computer System Interface), iFCP (Internet Fibre Channel Storage Networking) and FCIP (Fibre Channel over TCP/IP), as well as the iSNS (Internet Storage Name Server) and SLPv2 (Service Location Protocol v2) discovery protocols.

Method and system for information retrieval effectiveness estimation in e-discovery
Issued US 9,613,319
A server computing system determines a plurality of statistics for a plurality of test documents, determines a number of false negatives for a corpus of documents based on one or more of the plurality of statistics for the plurality of test documents. The classification of a document of the corpus of documents is a false negative if classification of the document by a classification model is negative and classification of the document by a user is positive. The server computing system…

The classification of a document of the corpus of documents is a false negative if classification of the document by a classification model is negative and classification of the document by a user is positive. The server computing system calculates an effectiveness of an information retrieval system on a corpus of documents based on the number of false negatives for the corpus of documents.

Methods and systems for automatic evaluation of electronic discovery review and productions
Issued US 9600568
Techniques are provided for automatic sampling evaluation. An automatic sampling evaluation system enables users to evaluate convergence of one or more search processes. For example, given a set of searches that were validated by human review, a system can implement a retrieval process that samples one or more non-retrieved collections. Each individual document's similarity in the one or more non-retrieved collections is automatically evaluated to other documents in any retrieved sets. Given a…
Techniques are provided for automatic sampling evaluation. An automatic sampling evaluation system enables users to evaluate convergence of one or more search processes. For example, given a set of searches that were validated by human review, a system can implement a retrieval process that samples one or more non-retrieved collections. Each individual document's similarity in the one or more non-retrieved collections is automatically evaluated to other documents in any retrieved sets. Given a goal of achieving a high recall, documents with high similarity can then be analyzed for additional noun phrases that may be used for a next iteration of a search. Convergence can be expected if the information gain in the new feedback loop is less than previous iterations, and if the additional documents identified are below a certain threshold document count.

Methods and systems for automatically generating semantic/concept searches
Issued US 8719257
In various embodiments, a semantic space associated with a corpus of electronically stored information (ESI) may be created and used for concept searches. Documents (and any other objects in the ESI, in general) may be represented as vectors in the semantic space. Vectors may correspond to identifiers, such as, for example, indexed terms. The semantic space for a corpus of ESI can be used in information filtering, information retrieval, indexing, and relevancy rankings.
