Predicting search engine switching behavior

Following up on the previous post, I found a few interesting papers (via Google) on user switching behavior of search engines.

• An Analysis of Search Engine Switching Behavior Using Click Streams
  Juan & Chang of Yahoo Inc
• Making Sense of Search Result Pages by Pedersen of Yahoo
• Defection detection: predicting search engine switching
  Heath & White of Microsoft
• Enhancing web search by promoting multiple search engine use
  White, Heath and co-workers at Microsoft
• Stream Prediction Using A Generative Model Based On. Frequent Episodes In Event Sequences by Laxman, Tankasali and White of Microsoft

Definitely worth reading in detail as the ways of building the models might be applicable to other behaviorally driven events.
