Has HP solved the problem of the over cluttered contact list of social networks? The computer maker is testing an “intelligent” mobile social network called Friendlee at its Palo Alto research center which analyzes the messaging and call activity on a person’s cellphone to build up a picture of a person’s closest contacts, reports the BBC. Those contacts that a person communicates with most rise to the top of the list, while those that aren’t used as much sink to the bottom. Friendlee also combs through the phone’s records to find the companies that a person uses, which can be then shared with contacts.

The product, which will be shown at September’s Mobile HCI conference in Bonn, Germany, came out of research that HP conducted last year on how people used social nets. HP’s director of its social computing lab Bernardo Huberman said that the research team found that “a link between any two people does not necessarily imply an interaction between them” and that while users may follow many on Twitter, they may only end up interacting with few. The idea then was to “tease out” the most relevant relationships to deliver them to the top of the list.

Friendlee also includes other features that lets users share their location with friends—much like Google (NSDQ: GOOG) Latitude. It can also share other “situational data”, including local time and weather, and allowing users to browse the friends lists of their close contacts. Users will be able to control how much information their friends see. The app currently can run on Windows Mobile, Android and Blackberry devices, but Huberman said it could be built for any device.
