TAR Solutions for a New Decade

These days, it seems impossible to talk about eDiscovery or document review without mention of Technology Assisted Review (TAR). In its broadest use as a technical term, TAR can refer to virtually any manner of technical assistance – from password cracking to threading to duplicate and near-duplicate detection. In its narrower use, TAR refers to techniques that involve the use of technology to predict (or to replicate) the decision a human expert would make about the classification or category of a document. In this narrower sense, TAR often comes with a version number – TAR 1.0, TAR 2.0, and more recently, TAR 3.0. While some are inclined to advocate for the superiority of a single approach, each version has its merits and place, and understanding the underlying process and technology is crucial to selecting the right approach for a specific discovery need.

We recently authored a white paper to offer a discussion of the variables to consider when choosing the right TAR workflow for a specific matter, as well as the main principles behind different TAR solutions. By doing so, we make the claim that true preparedness lies in understanding the range of core technology within the TAR landscape, and further knowing how and where to access the right combination of people, process, and technology to meet any discovery need.  If you or your team have had mixed results with TAR, or want some guidance on deciding your approach with TAR in your next matter, you may find this paper helpful.

TAR Solutions for a New Decade


Expanding data volumes are having a significant impact on ediscovery, but what are the specific challenges being faced? Lighthouse’s Nick Schreiner outlines six challenges when working with large data sets and offers up insights into how to address these challenges with data re-use, AI, and big data analytics in a recent blog: https://lnkd.in/dYjcY6W


eDiscovery itself is a big data challenge, but recent advances in AI and machine learning can help mitigate risks by breaking down the silos of individual cases and leveraging prior case data. Lighthouse’s Karl Sobylak discusses the benefits of bringing technology to bear to understand large data sets at scale in a recent blog: http://ow.ly/QbzZ50COKK8


As data volumes continue to grow so does the need for AI and machine learning. In fact, adopting AI can be a catalyst for revitalizing your organization’s ediscovery model. Lighthouse’s Rob Hellewell makes the case for AI including cost reduction, lower risk, and improved win rates in a recent blog: http://ow.ly/MoNs50CMwws


Artificial intelligence, advanced analytics, and machine learning are no longer new to the ediscovery field. While the legal industry admittedly trends towards caution in its embrace of new technology, the ever-growing surge of data is forcing most legal professionals to accept that basic machine learning and AI are becoming necessary ediscovery tools.

However, the constant evolution and improvement of legal tech bestow an excellent opportunity to the forward-thinking ediscovery legal professional who seeks to triumph over the growing inefficiencies and ballooning costs of older technology and workflow models. In this article, we provide you with arguments on how leveraging the most advanced AI and analytics solutions can give your organization or law firm a competitive and financial advantage, while also reducing risk.


As the proponents of policy and creators of contracts, it’s well understood that the legal department’s job is, first and foremost, to manage risk. This involves identifying potential legal and regulatory issues as soon as possible, developing a profile of potential legal risks, avoiding those risks with compliance programs, and dealing with the ones that slip through the cracks.

What is perhaps less well understood is how dramatically the concept of “risk” has evolved in recent years. Between digital transformation and technological innovations, new data privacy laws, cyber vulnerabilities, and an increasing spotlight on corporate culture, values and diversity practices — risk management today is not your grandmother’s limitation of liability clause. For today’s legal departments, risk management goes hand-in-hand with data stewardship. What type of information is retained or destroyed is becoming just as important as how information is organized and leveraged. Yet, data disparity is on the rise.


When we set out with the goal of enabling knowledge workers across dispersed enterprise teams to gain control of their data, we didn’t start small. We knew that if we built a solution that worked for the most onerous, meticulous, and urgent use cases, like eDiscovery, we were on to something.

That’s why we’re thrilled to receive the LegalTech Breakthrough Award for eDiscovery Solution of the Year.

LegalTech Breakthrough selected our Knowledge Integration Platform for its representation of “a new category of legal tech products that doesn’t just “collect data,” but connects, centralizes, indexes, and processes it — transforming data into accessible, secure, and private knowledge.”
