15. • Step 1: Collaborative Task Mining:
– extract frequent demand sequences from large scale browser logs
– achieved via frequent sequence mining problem
• Step 2: Task-based Demand Prediction
– predict the upcoming demand of a user given the current browsing session
– estimate the probability of each demand d ∈ D being the follow-on demand of
the current session
• Step 3: Task-based Recommendation
– Provide site-level recommendations (based on predicted demands)
– Provide link-level recommendations (heterogeneous recommendations
based on browsing behavior)
