Net Perceptions Debuts GroupLens Version 3.0

Net Perceptions, a provider of Internet personalization tools, released an updated version of its GroupLens Recommendation Engine, making it easier to deploy and integrate.

Combining experience gained during successful implementations in demanding online environments for customers such as Amazon.com, CDnow, E!Online, iVillage, N2K, and Planet Direct, GroupLens has matured as an industrial strength tool, the company said.

GroupLens Version 3.0 is collaborative filtering technology that automates word-of-mouth recommendations, enabling Web sites to generate online recommendations in real time and tailor product offerings to individual customers.

New features include integration with Broadvision's One-to-One, Microsoft's Site Server 3.0, and Vignette's StoryServer, and a customization capability to integrate customer preference predictions with business rules and policies (for example, R-rated movies would not be recommended to an 8-year-old child).

Version 3.0 yields real-time recommendations up to three times faster than before, the company said. And, customers can now access the information contained in their own GroupLens databases and leverage it for targeted planning and marketing activities.

"GroupLens Version 3.0 elevates the personalization solutions available to Net Perceptions' customers, helping them make real-time, on-target predictions about individual user preferences and, ultimately, retain loyal customers," said Steven Snyder, Net Perceptions' president and chief executive officer.
