TAR vs. Keyword Search Challenge, Round 6 (Instant Feedback)

Even with a large pool of participants, ample time, and the ability to hone search queries based on instant feedback, nobody was able to generate a better production than Technology-Assisted Review (TAR) when the same amount of review effort was expended. It seems fair to say that keyword search often requires twice as much document review to achieve a production that is as good as what you would get TAR.


Have You Tried Using a ‘Nearest Neighbor Search’?

A Nearest Neighbor Search is perhaps the simplest procedure you might conceive of if presented with a machine-learning-type problem while under the influence of some sort of generalized “veil of ignorance”. Though there exist slightly more complicated variations in the algorithm, the basic principle of all of them is effectively the same.


Selecting TAR Software and Service Providers?

Technology Assisted Review (TAR) is useful for many tasks within the Electronic Discovery Reference Model (EDRM), with one of its central applications being its use in determining the relevancy of documents in the review stage of eDiscovery in support of document production obligations. To engage in the management of this important workflow, the producing party needs access to TAR software and the decision on what software to use goes hand-in-hand with the service provider selection.


EDRM Releases Technology-Assisted Review Guidelines

EDRM has released a comprehensive set of guidelines that aim to objectively define and explain technology-assisted review for members of the judiciary and the legal profession. The TAR Guidelines represent the first step in a multifaceted effort to develop a broad understanding of TAR and to encourage its adoption. Under the auspices of the Bolch Judicial Institute and EDRM, a second document, a protocol for when and under what circumstances TAR should be used, is currently being developed by a drafting team of 40 judges, lawyers, and e-discovery experts who attended a 2017 conference focused on TAR best practices, hosted by Duke and EDRM.

The Importance of Contextual Diversity in Technology Assisted Review

Contextual diversity refers to documents that are different from the ones already seen and judged by human reviewers. The contextual diversity algorithm identifies documents based on how significant and how different they are from the ones already seen and then selects training documents that are the most representative of those unseen topics for human review.

‘Document Tsunami’ Driving Lawyers to Upskill in TAR

A prominent Victorian judge has highlighted the growing need for lawyers to expand their knowledge on technology-assisted review (TAR) workflows, noting that if they don’t they’re going to be deficient in their capacity to service clients.
