Borders—national, state, and city—exist for historical, geographic, cultural reasons. But how do they relate to communities people form through close interactions with others? As highlighted in a New York Times Op-Ed on Phone-call Cartography, researchers are using aggregated, anonymous cell phone data to map people’s self-formed communities and understand how they intersect with administrative borders.
Extracting Descriptions of Problems with Product and Services from Twitter Data by AT&T Researcher Narendra Gupta was named Best Paper at this year’s Social Web Search and Mining Workshop.
The paper describes a new way to mine Twitter data to find customer-complaint tweets related to a company’s products or services. Recently the technique helped generate more accurate alarms, sometimes before a ticket was opened.

Michael I. Jordan will discuss Bayesian nonparametric modeling based on completely random measures, while giving examples of how recursions based on these measures lead to useful models in several domains, including protein structural modeling, natural language processing, compu- tational vision, and speech recognition. The talk, part of AT&T's Distinguished Speaker series, will take place October 5 at 3:30 in the Florham Park auditorium. Click here for directions.
According to Microsoft Academic Search (currently in beta), a resource for academic and technical publications, Computers and Intractability: A Guide to the Theory of NP-Completeness by Michael Garey and AT&T Labs executive director David Johnson is the most cited computer science book. Published in 1979, this book was the first on the theory of NP-completeness and computational intractability and is now considered a classic.
AT&T Research is launching a limited trial of ECHO, a social music listening service that lets music lovers listen to the music they want "together". Users can follow a DJ (or be one), chat and use social networking concepts to discover new music or just spread the music love. With Napster as a partner, song choice is almost unlimited.
