1. A method for segregating multiple action logs of at least one multitasking user to derive at least one behavioral pattern of the at least one multitasking user, comprising the steps of: obtaining multiple action logs for a user from multiple web sites, configuration information, domain knowledge, at least one task history and open task repository information; correlating the multiple action logs, configuration information, domain knowledge, at least one task history and open task repository information to determine a task associated with each of one or more actions in the multiple action logs, where there is no explicit indication of the task associated with each of the one or more actions performed, wherein said correlating comprises: associating each of one or more actions in the multiple action logs with a task in the open task repository; computing a confidence score for each task in the open task repository associated with the one or more actions, said computing comprising: computing a first probability distribution for a set of tasks associated with the user from the open task repository as a normalized weighted average of distributions over a pre-determined number of previous actions restricted to the set of tasks performed by the user; computing a distribution of recency of tasks opened in the set of tasks; and combining the probability distribution and the distribution of recency of tasks to determine a second probability distribution for the user; and identifying the task with the highest confidence score, wherein the highest confidence score corresponds to the task having the maximal probability in the second probability distribution; automatically segregating the multiple action logs of the at least one multitasking user on a per-task basis based on the identified task; and using the multiple action logs that have been segregated on a per-task basis to derive at least one behavioral pattern of the at least one multitasking user and a sequence of one or more additional actions based on the identified task and the at least one behavioral pattern.
