Abstract

An information processing system, a computer readable storage medium, and a method to detect and block a robot data aggregator from accessing a website. A method includes defining a set of important features of business operations associated with users using a website. A feature value for each important feature is extracted from collected session data of a user session using the website. A user classifier classifies the user session as being with a human user or a robot user. Based on the classifying, access to the website by a robot user is blocked. Training user session data is also generated from the collected user session data thereby the user classifier learns and improves accuracy and reliability in detecting the type of user in a user session.
