iPhrase Technologies, a Cambridge, Mass., maker of of software that allows users to pose questions in plain English, has expanded its relationship with LexisNexis Group, a Dayton, Ohio, provider of information to legal, corporate, government and academic markets.

Under a pact to be announced today, iPhrase's technology will be integrated into LexisNexis' Advertising Red Books, a resource for the ad industry, and Directory of Corporate Affiliations, a database of corporations and their subsidiaries.

For example, a user of Advertising Red Books might ask, "What are all the agencies that represent Ford?" or "Who spends more than $100 million in print-based advertising?"

The iPhrase software searches all relevant databases, collects the most appropriate answers and presents them back to the user in real time, eliminating the need to sift through multiple or irrelevant results.

"LexisNexis' adoption of iPhrase's One Step solution into these popular offerings will ensure that requests for information will be quickly answered with accurate results, right when they're needed," said Noam Ben-Ozer, iPhrase co-founder and CEO.

The agreement, comes three months after LexisNexis' parent, Reed Elsevier, led iPhrase's $25 million second round of financing. Both companies expect broader collaboration marrying iPhrase's search technology with Reed Elsevier's information services.

iPhrase is privately held. In addition to its Cambridge headquarters, it has an office in San Mateo, Calif. Other customers include investment giant Charles Schwab and technology news organization CNET.
