Ask Catalyst: In TAR, What Is Validation And Why Is It Important?

[Editor’s note: This is another post in our “Ask Catalyst” series, in which we answer your questions about e-discovery search and review. To learn more and submit your own question, go here.]  

Twitter_Ask_Catalyst_John_TredennickThis week’s question:

In technology assisted review, what is validation and why is it important?

Today’s question is answered by John Tredennick, founder and CEO.

Validation is the “act of confirming that a process has achieved its intended purpose.”[1] It is important to TAR for several reasons, including the need to ensure the TAR algorithm has worked properly and because Rule 26(g) requires counsel to certify that the process they used for producing discovery documents was reasonable and reasonably effective.[2]  While courts have approved validation methods in specific cases,[3] no court has yet purported to set forth specific validation standards applicable to all cases or for all TAR review projects.

A Discussion About Dynamo Holdings: Is 43% Recall Enough?

blog_john_and_tomIn September 2014, Judge Ronald L. Buch became the first to sanction the use of technology assisted review (aka predictive coding) in the U.S. Tax Court. See Dynamo Holdings Limited Partnership v. Commissioner of Internal Revenue, 143 T.C. No. 9. We mentioned it here.

This summer, Judge Buch issued a follow-on order addressing the IRS commissioner’s objections to the outcome of the TAR process, which we chronicled here. In that opinion, he affirmed the petitioner’s TAR process and rejected the commissioner’s challenge that the production was not adequate. In doing so, the judge debunked what he called the two myths of review, namely that human review is the “gold standard” or that any discovery response is or can be perfect. Continue reading

How Many Documents in a Gigabyte: 2016 Edition

How_Many_DocsReaders of our blog will know that I have a continuing interest in answering the perennial e-discovery question: “How many native documents are in a gigabyte?” I started thinking about this in 2011 and published my first article on the subject based on analysis of 18 million files. Challenging industry assumptions, which ran from 5,000 to as many as 15,000, I concluded that the average across all files—based on that sample—was closer to 2,500. Continue reading

Gigabyte Expansion in E-Discovery Hosting: You Get What You Pay for; You Pay for What You Get

Catalyst_Blog_Gigabyte_ExpansionAn old friend called me recently to talk about a beef he had with his e-discovery provider. “What’s up?” I asked when I realized who it was. He told me he thought he had done everything right in setting up his last e-discovery project. He sent out an RFP to several vendors, asked all the right questions and then picked the bidder with the lowest per-gigabyte price to host the documents. Everything seemed like it was on track.

“So what’s wrong with that,” I asked. “You went for the low bidder and locked them in with an ironclad contract. Getting hosting for that kind of per-gigabyte price seems like a steal.”

My friend sighed in response. “What happened was that I didn’t read the fine print.” Continue reading

In First for UK, High Court Master Approves Use of TAR

Taking his lead from the seminal U.S. case, Da Silva Moore v. Publicis Groupe, a master of Britain’s High Court of Justice has approved the use of technology assisted review, becoming the first case to do so in the United Kingdom and only the second case outside the U.S. to approve TAR.

In a written decision issued Feb. 16, 2016, in the case Pyrrho Investments Ltd. v. MWB Property Ltd., Master Matthews, who is similar in responsibility to a magistrate judge in the U.S. federal court system – provided his reasons for his approval of the parties’ request to use TAR in a case involving some 3.1 million electronic documents.

Moving Beyond the EDRM: Creating a Mental Model of the E-Discovery Process

ediscovery-mental-modelIn the user interface (UI) and user experience (UX) world, one of the ways people design successful software is through the creation of a “mental model” of the underlying processes. Mental models have been around since the 1940s and used for different processes but the concept caught hold in software because it gave designers a framework to understand user needs and the problems they were trying to solve.

According to one of the pioneers of Internet usability, Jacob Neilson, “mental models are one of the most important concepts in human-computer interaction.” We use them to inform our software design and we wanted to share one that we created to model the e-discovery process. Continue reading
