    Patent number: 9836539
    Abstract: Methods and system for providing a list of recommended items in response to a query includes obtaining user navigation information relevant to the query from a plurality of user access logs associated with the plurality of users.

The navigation sequence represents the users browsing behavior and identifies answers to the queries. A set of temporal parameters for analyzing the user navigation information is identified. The temporal parameters define time frame for analyzing the user navigation information. A list of recommended items to navigate is dynamically generated by analyzing user navigation information obtained from user access logs using temporal parameters. The generated list includes items that are most relevant to the query. The generated list of items is returned in response to the query and represents an optimal result.
