IBM’s artificial intelligence-powered cognitive computing platform Watson has come a long way from its days playing “Jeopardy.” Deployed last year for legal professionals as the engine behind legal research platform ROSS , Watson has recently made further inroads into the legal space with the December 2016 launch of Watson Discovery Service .

In an email, IBM told Legaltech News that the updates to Watson Discovery Service enable developers to implement a “machine learning model” in their search tools, which allows the tools to understand how certain language terms are related on a deeper level. The service allows developers to create search and e-discovery tools using Watson’s technology—which can comprehend language and data on an almost human level—to find relationships in structured data and unstructured data, and categorize and index such data into a searchable database.
