blog-5vendorsMany vendors these days claim that their technology-assisted review products use a protocol called Continuous Active Learning. But how can you, as an e-discovery professional, be certain about those claims?

The reason this matters is that CAL has  been scientifically proven to be superior to other forms of TAR. In a landmark, peer-reviewed study published last year, e-discovery pioneers Maura Grossman and Gordon Cormack demonstrated CAL’s superiority. Their research proved that CAL was far more effective at finding relevant documents (at a much lower cost) than the one-time training methods used by earlier, TAR 1.0 systems. Continue reading

Webinar Redux: Here’s the Recording of Our Program on TAR and Transparency


If you missed Catalyst’s recent webinar, Solving the Transparency Issues in Technology Assisted Review, here is your second chance. The video above is a recording of the full webinar.

What is the transparency issue? Well, if you happened to read U.S. Magistrate Judge Andrew Peck’s decision earlier this year in Rio Tinto v. Vale, you have an understanding of why transparency is a concern with regard to the use of TAR. Although TAR is now so widely accepted that it has become—as Judge Peck said—black letter law, there remains significant uncertainty over the degree of transparency and cooperation required with respect to the training sets used in TAR.

Case Study: Is It Ever Too Late in A Review to Start Using TAR?

Case_Study“It’s never too late,” people often say. But is that true for technology assisted review? If a legal team has already put substantial time and effort into manual review, can TAR still be worthwhile? That was the issue presented in a patent infringement case where the client’s approval to use TAR came only after the law firm had manually reviewed nearly half the collection. Even that late in the game, Insight Predict produced substantial savings in time and cost.
