Fios, Inc. unveiled upgrades to Prevail. With this upgrade Fios will offer concept-based searching capabilities. The new upgrades will be available for client use by the middle of March. Fios’ Prevail is a Web-based tool designed to help legal teams manage, search and produce vast amounts of electronic evidence. The concept-based search technology is being added to Prevail via Fios’ licensing partnership with Engenium, Corp., developer of the intelligent concept-based search technology called Semetric. Prevail is hosted by Fios and requires no client site setup or configuration. The only system requirements for Fios’ clients are Internet Explorer 5.5 and Windows 98. Pricing is based on a per-megabyte basis, thus costs don’t vary based on the number of users accessing Prevail, nor the amount of time they spend online.
