The invention provides a
Skyline double-filtering retrieval method based on multi-medical factors in a mobile O2O environment, which aims to solve the problem that a conventional mobile network
result set is too large. The technical key point is that the
Skyline double-filtering retrieval method comprises the following step: on the basis of medical
stream data and checking requests, extracting dimension sub-spaces of related medical attributes from the checking requests in parallel in a whole space by a cloud terminal, wherein d is a whole space dimension number, k is a sub-space
data dimension number, and the field (dimension) in which a user is interested is extracted from the whole space F, namely k; and sequencing k-dimension sub-spaces according to preference degrees of a
client terminal to the medical attributes, thereby obtaining a sequenced dimensional-grid index. The
Skyline double-filtering retrieval method has the beneficial effects that feedback data can be continuously interacted and screened in a
data stream mode, the precision is high and the method is applicable to big-data environments, accurate information which meets requirements can be provided by an interaction platform provided by users and data sections, and thus the accuracy of final decisions of the users and rapid user decision experience can be improved.
