Personas from Data

Giving Faces to Data : Automatic Persona Generation Using Actual Online Analytics Data

Personas are fictitious people describing an organization's core customers or users. Personas were introduced by Alan Cooper in the 1990s as a thinking tool for software developers and designers, and have since then been applied in many contexts, including marketing and advertising, corporate sales, and public health.
Automatic Persona Generation (APG) is both a methodology and a system for automatic creation of personas from online analytics data.
