Abstract: A system presents content to a website user based on a predicted future intent of the user. Hidden Markov models (HMMs) are developed based on a hierarchical and relational graph of a website. Given a sequence of observed actions performed by a user on the website, a HMM can be used to predict a likely intent the user has most recently acted on. Using a deterministic algorithm or a Monte Carlo Tree Search algorithm, the system can then predict likelihoods that each possible user intent associated with the website is a future intent of the particular user. Website content and formatting can be adjusted based on predictions about a user's future intents.
