Messages generated by user accounts in a social networking application over a period of time are processed to determine the subjects and topic associated with the messages, as well as the geographical locations of the users associated with the user accounts, and the times when the users associated with the accounts are most active. The determined, subject, time, and location information is used to create a model that may be used to predict whether a user in the social networking application is willing, available, and has the knowledge or topical affinity to answer a question proposed by another user in the social networking application based on a subject, time, and/or location associated with the question. When a user enters a question, the user may be presented with a list of their friends or contacts ranked according to the probabilities generated by the model. |
