The invention discloses an entity competition relation data mining method based on space-time attributes. According to the method, entity competition relation detection and a leading edge computer technology are combined, the defect that a traditional competition relation data mining method does not consider space-time attribute influence is overcome, three factors of entity user comments, entityuser comment time and entity space positions are scientifically fused, and the competition relation between entities is scientifically and accurately quantified. The value range of the finally mined entity competition relation data is [0, 1], and the problems that results of a traditional competition relation mining method and a competitor recognition method cannot be understood by non-technicians, and finally manual processing and screening are needed are effectively solved.
