The Potential of Artificial Intelligence

According to the Electronic Discovery Reference Model (EDRM) (1), artificial intelligence (AI) refers to the capability of machines to mimic aspects of human intelligence such as problem-solving, reasoning, discovering meaning, generalizing, predicting, or learning from experience. AI includes both unsupervised and supervised machine learning and has many other processes, such as natural language processing (NLP). In the context of HaystackID Discovery Intelligence, AI describes the automated discovery processes used to classify, categorize, summarize, predict, and provide insight and intelligence regarding ESI. This application of AI by HaystackID is accomplished through the expert application of proprietary statistical, rule-based, and algorithmic means. The potential of AI is realized in HaystackID Discovery Intelligence in areas ranging from detecting sensitive data (e.g., from PII and PHI to SSNs and License Plate Numbers) and identifying entities to support cyber breach responses as part of ReviewRight® Protect™ services to the evaluation and classification of legal documents reviewers as part of HaystackID ReviewRight Match® services. Three examples of AI-enabled services available as part of HaystackID Discovery Intelligence include:

The Power of Machine Learning

According to IBM (4), machine learning is a branch of AI and computer science that focuses on using data and algorithms to imitate the way humans learn, gradually improving its accuracy. In HaystackID Discovery Intelligence, HaystackID leverages predictive coding, a term used to describe a technology-assisted review (TAR) process which involves using a machine learning algorithm to distinguish relevant and non-relevant documents based on a subject matter expert’s coding a training set of documents. (5)

HaystackID Discovery Intelligence predictive coding is based on active learning. Active learning is a process, typically iterative, whereby an algorithm is used to select documents that should be reviewed for training based on a strategy to help the classification algorithm learn efficiently. (6) HaystackID Discovery Intelligence typically leverages a Continuous Active Learning® (CAL®) predictive coding protocol. In CAL, the TAR method developed, used, and advocated by Maura R. Grossman and Gordon V. Cormack, after the initial training set, the learner repeatedly selects the next-most-likely-to-be-relevant documents (that have not yet been considered) for review, coding, and training, and continues to do so until it can no longer find any more relevant documents. There is generally no second review because, by the time the learner stops learning, all documents deemed relevant by the learner have already been identified and manually reviewed. (7) Two examples of machine learning-enabled successes delivered by HaystackID as part of HaystackID Discovery Intelligence include:

Enterprise Solutions Case Study

A Look at How Workflow, Analytics, and CAL® Can Make a Difference in Cost Savings

In this case study, a global manufacturer approached HaystackID to assist with processing, early case assessment (ECA), hosting, and managed review for a mid-sized, time-sensitive litigation matter. The client collected and securely transmitted approximately 650 GB of data, comprising several million documents, to HaystackID for processing and hosting. HaystackID, leveraging HaystackID Discovery Intelligence, worked collaboratively to create workflow efficiencies that yielded considerable cost savings. The combined team developed a workflow that used structured analytics and TAR (CAL) to deliver substantial and documented cost savings in the high six figures while completing the project. (8)

Speed, Slack, and Specialization – A Precision Approach to Second Requests

During the COVID-constrained summer of 2020, HaystackID supported a leading global finance platform company and its internationally recognized outside counsel in responding to a Department of Justice (DOJ) Second Request based on a proposed acquisition of a highly regulated company. As part of the Second Request, HaystackID collected and evaluated 18 TB of data, including critical Slack messages and files stores from onsite and remote locations from more than 17 types of data stores. Within 106 days, HaystackID completed approximately 300 collections and developed custom tools and processes. These custom tools and processes included innovative Slack-specific communications heat maps, predictive coding processes (CAL), and private message privilege identification to enable a compliant response to a complex investigation request, ultimately enabling a compliant response completion of the proposed acquisition.

Shaping Outcomes with eDiscovery: A Complex Defense of Intellectual Property

In this matter between two technology-enabled manufacturing firms, HaystackID became a decisive contributor based on its aggressive yet controlled delivery of HaystackID Discovery Intelligence, including ReviewRight services to help its client find, understand, and learn from evidence. HaystackID Discovery Intelligence efforts collected 10 TB of ESI, reduced ESI from 10 TB to 430 GB through culling and processing, and further reduced ESI volume from 430 GB to 120 GB through review-centric analytics and TAR. The remaining 120 GB of ESI, about 550,000 documents, was completed within 90 days of initial collection through a combination of on-premises and remote reviews leveraging approximately 200 qualified expert reviewers. These efforts resulted in the identification of data-centric metadata changes that, when viewed within the context of all available ESI, substantiated the validity of the complaint of HaystackID’s client, providing the proverbial smoking gun of evidence necessary for the successful defense of intellectual property.
