The Tfitter project aims to store Twitter data with Scala in backends such as -- PostgreSQL -- Berkeley DB Java Edition -- Lucene for subsequent analysis of the contents and the conversations in the context of Machine Learning and Natural Language Processing. The originator, Alexy Khrabrov, is a researcher at Thayer School of Engineering at Dartmouth. http://www.khrabrov.net/ points to Alexy's personal and academic pages. See Alexy's Scala blog, http://la.scala.la/ for Scala discoveries in the making of Tfitter.
