Abstract
A method for the construction of commuting matrices using call detail records, computer programs and a use for providing user's mobility information, including computing mechanism for constructing a commuting matrix according to phone call records of a user. The method includes: a) providing a user's origin time range; b) providing a user's destination time range or second user's origin time range; c) constructing the commuting matrix based on call detail records using the user's origin time range and the user's destination time range; d) comparing the commuting matrix with a predetermined ground truth matrix and obtaining a comparison result; and e) optimizing the origin time range and/or destination time range based on the comparison result.
