1. A computer-implemented method for modeling a user intention during network navigation, the method comprising:
- predicting, based on a statistical multi-step n-gram probability model, an optimal information goal of the user; and
wherein the optimal information goal is based on a sequence of previously visited network content pieces and a globally optimized navigation path through the sequence.

Abstract
The disclosed subject matter models or predicts a user'"'"'s intention during network or WWW navigation. Specifically, a statistical multi-step n-gram probability model is used to predict a user'"'"'s optimal information goal. The optimal information goal is based on a sequence of previously visited network content pieces and a globally optimized navigation path through the sequence.
