Widget-based component pushing method, device, control unit and system

Embodiments of the invention disclose widget-based component pushing method, device, control unit and system. The method includes: acquiring related components matching with a search identifier, extracting feature items of stored components, and generating a feature matrix corresponding to the related components; screening neighbor components meeting preset similar conditions according to the feature matrix; acquiring user similarity evaluation values of the neighbor components, and generating a similarity evaluation matrix corresponding to the neighbor components; calculating neighbor component similarity prediction values according to the similarity evaluation matrix, and pushing the neighbor components meeting the preset similarity evaluation conditions. The problem of the prior art that screening the neighbor components by starting with other components used by other users is inaccurate is overcome; good push results are still guaranteed even when user similarity evaluation values lack.
