Catalyst is First to Integrate TAR 2.0 Continuous Active Learning into the Review Process Helping Clients Save Time and Money on Discovery

NEW YORK, Feb. 3, 2015—Further expanding its leadership as the first company to offer TAR 2.0 technology, Catalyst today released “Active Review” functionality that integrates Continuous Active Learning (CAL) protocol into the review process.


Active Review runs in the background of the review and continuously applies its learning algorithm to the document population. Every judgment that a reviewer makes about a document enables the system to grow smarter about which documents in the population are likely to be relevant or non-relevant. As the system grows smarter, clients save on time and review costs because the system brings more relevant documents to the front of the queue. As a result, you can stop the process earlier than with TAR 1.0 “one-time training,” which means lower costs and quicker review.

No other product on the market has a feature like Active Review. It eliminates the traditional separation between linear and Technology Assisted Review, through a single, integrated workflow. Among the significant benefits:

  • Continuous Rather than One-Time Training: Active Review integrates CAL directly into the review platform and continually ranks all of the documents, allowing for continuous rather than one-time training. Clients save as the algorithm gets smarter about the documents.
  • Handles Rolling Uploads: You can add more documents to the collection at any time and they will be immediately incorporated into the ranking.
  • Subject Matter Expert: Active Review eliminates the need for SMEs to train the system, as is required by other platforms.
  • Faster Review at Lower Cost: The integration of CAL directly into the review process means you start your review more quickly and get through it more efficiently.

“Continuous Active Learning is a proven way to find relevant documents more quickly, which means our clients can reduce review costs and save time in the bargain. We started promoting continuous learning protocols for larger cases several years ago and our clients immediately realized savings,” said John Tredennick, CEO and founder of Catalyst. “Today, we are further integrating this advanced protocol into our standard review module so all clients can take advantage CAL, even in smaller review projects.”

Catalyst is the only e-discovery company to incorporate CAL into its technology. A 2014 peer-reviewed study by two of the leading experts on e-discovery, Maura R. Grossman and Gordon V. Cormack, concluded that CAL demonstrated superior performance over other TAR methods, while avoiding many of their problems, and that CAL found relevant documents more quickly and with less human effort.
