Claim:
1. A method for identifying personal context of at least one user having a portable mobile communication device at a location for deriving social interaction information of the user, the method comprising: determining a location of at least one user within a predefined range by identifying a personal context of the user at the location, wherein the personal context of the user is identified using at least an external sensor and an internal sensor embedded in the mobile communication device; assigning predefined confidence values to the identified personal context, wherein the predefined confidence value is associated with a probability distribution function and an observation from a given sensor; obtaining current location information relating to the user at the location by fusing the assigned confidence values; grouping, based on predefined density criteria, at least two users having similar current location information at the location of the user; estimating, using the external sensor and internal sensor, a straight line distance between the at least two grouped users; and deriving social interaction information of the user by fusing the current location information of the user, the estimated straight line distance, and data received from a web sensor.
