  • Patent number: 10643486
    Abstract: Steps of a method of case matching for a tutor user are implemented by a server that stores a plurality of tutee cases each including a lecturing location and a subject demand, and a tutor user registration corresponding to the tutor user and including a tutor location, a lecturing subject and a commuting distance limit. The server determines whether the tutee cases include a target tutee case of which the subject demand matches the lecturing subject and a commuting distance between the lecturing location of which and the tutor location is not greater than the commuting distance limit. When the determination is affirmative, the server generates a filtered case result indicating the target tutee case.
