Lexum is an emerging leader in artificial intelligence for legal research and legal service delivery

2017-07-31 / By Lexum

Artificial intelligence (AI) and its role in the legal industry is under the spotlight at the moment with efforts being made to utilize AI in the provision of a whole range of legal services. Lexum is one of the leaders in this emerging industry where we are using artificial intelligence to maximize legal research capabilities. Lexum’s work in artificial...


Our technology enables organizations of all sizes to deliver content to end users with unparalleled speed and efficiency. We are constantly looking for new ways to automate and streamline the operation of legal information databases. Over the years, this has led us to replace manual editing by complex algorithms based on heuristics whenever possible.

One such example is Lexum’s citator, Reflex, which is used to automatically insert links on legal citations included in the text body of legal documents.

Another example is Decisia’s auto-fill feature, which enables our clients to extract all sorts of metadata values directly from the body of their unstructured documents in one single click.

This expertise, coupled with the large volume of legal information available to Lexum in parsable format, puts us in a unique position to leverage the opportunities presented by recent developments in the field of artificial intelligence, machine learning and deep learning.

Innovation has been part of Lexum’s DNA since the beginning. Twenty-five years ago, we started providing access to Supreme Court of Canada decisions on a Gopher server before the Web was even invented. Eventually, static webpages gave place to dynamic websites, and more recently bespoke software code gave way to Software-as-a-Service (SaaS) products. Overall, in collaboration with the clients and partners who have trusted us, we have transformed the legal publishing industry. We intend to continue doing so.
