Using a content database to infer context information for activities from messages

摘要

Some embodiments of the present invention provide a system that infers activity-related context information from a message. Upon receiving the message (202), the system looks (204) for activity-related keywords in the message, wherein the activity-related keywords are from a content database. If one or more activity-related keywords are found in the message, the system infers (206) message-related context information from the one or more activity-related keywords. Next, the system uses the message-related context information to facilitate recommending an activity to a user (212).
