CASE STUDY

Combining Legal Expertise with Technology during Early Case Assessment

Our client had a huge set of documents that needed to be reviewed as part of an early case assessment (ECA). We used Brainspace software to accurately identify the most relevant documents, saving both time and personnel costs.

Our Solution

Our Advanced Project Management division assembled a team to manage the review, including a technical specialist, a senior associate/project manager, a junior associate and eight legal review analysts. We agreed with our client that we would use Brainspace, a machine-learning software that intelligently detects unique phrases in massive unstructured datasets.

Brainspace offers a visual approach to analytics, delivering concept search, document clustering, communication analysis and predictive coding in a single, intuitive workflow. With that 360 degree perspective, we were able to quickly focus on the sections of the dataset which contained documents most relevant to the investigation. In this case, our initial review work was centred on specific communication lines, namely emails between particular key personnel, to identify who was communicating the most and the topics that were under discussion.

Once reviewed, those documents were then used with our technology assisted review (TAR) system to train Brainspace to identify similar relevant documents within the broader dataset.


By combining technology with our legal expertise, we were able speed up the investigative process for our client and produce the accurate results necessary for a successful ECA.

The Results

901,969 documents were initially captured in the collection, but after applying the relevant date range, that number was reduced to 394,576. Using Brainspace and our TAR system, we were able to then reduce the dataset for review to 238,169. This meant that 145,132 documents did not require any review, and the relevant document output was 27,181.

By combining technology with our legal expertise, we were able speed up the investigative process for our client and produce the accurate results necessary for a successful ECA. Working within urgent deadlines we identified all potentially relevant data sources and custodians. We instructed forensic specialists to extract data from the systems of our client to then process this ready for review.
