Abstract:
Disclosed are a location service-based method, device, equipment for crowd classification, and a storage medium. The method comprises : acquiring geographical location information of users on the basis of a location service, the geographical location information comprising POI information associated with time; performing a cluster analysis on all of the geographical location information of any user in a preset period, acquiring a lifestyle trajectory vector table; constructing a raw user trajectory matrix by utilizing the lifestyle trajectory vector table; employing a singular value decomposition algorithm for matrix decomposition of the raw user trajectory matrix, acquiring a reconstructed user trajectory matrix; determining, on the basis of the reconstructed user trajectory matrix, a socially similar user corresponding to the target user. The process by which the location service-based method for crowd classification acquires a socially similar user corresponding to a target user is easy to operate, the need to collect a large volume of data is obviated, and the acquired socially similar user is of increased similarity and objectivity to the lifestyle of the target user.
