New Scientific Paper for TREC Conference
ZL recently published a scientific paper for the NIST/Text Retrieval Conference (TREC), showing the efficiencies of various eDiscovery approaches. We studied the Enron corpus of documents, about 3,000,000 emails from over 100 Enron employee mailboxes, and found that most companies can dramatically decrease review costs and legal liability if they employ an enterprise-wide search rather than a custodian-by-custodian search.
Using two fully-independent teams, ZL tested the increased responsiveness of the enterprise-wide approach and the results were striking: The enterprise-wide search yielded 77 custodians and 302 responsive email messages, while the custodian approach failed to identify 84% of the responsive documents.
This shouldn’t be too surprising since “eDiscovery has developed to the point where, for many, the ability to search across all custodians in a quick and timely manner has become a critical requirement,” says George Socha of Socha Consulting, a leading eDiscovery consultancy. “The shortcomings of a limited custodian search, or for that matter, any other arbitrary search limitations, can be substantial. Searching across a broad swath of data can have enormous value to the large enterprise, reducing uncertainty in the eDiscovery process by improving the chances that legal teams have examined the most important data available to them.”
