Aaron Zinman and Doug Fritz from the Fluid Interfaces research group at the MIT Media Lab will present “Data Portraiture and Topic Models” at Technarte 2010.
They will present a selection of some projects done by their group like Lanscape of Words (a series of different data visualizations created from personal twitts on Twitter), Personas, Connectus or Theme Stream amongst others.
Topic models provide a simple way to analyze large volumes of unlabeled text. A “topic” consists of a cluster of words that frequently occur together. Using contextual clues, topic models can connect words with similar meanings and distinguish between uses of words with multiple meanings.
Data Portraiture, is the generative process of creating visual representations of compressed individual information into generative data portraits with the use of topic modeling. Aaron Zinman and Doug Fritz will showcase their work to highlight the potential direction in this emerging field.
