Abstract
A method that includes establishing a layered attribute description network according to description values of the filtering requirements; extracting description values that are in the attribute description network; establishing a mapping relationship between the filtering requirements and the attribute description network, generating a path dependency graph; performing traversal comparison between the description values included in the description information of the data object to be filtered and description values in the path dependency graph; if all description values of one description path are included in the description information of the data object to be filtered, recording the description path as a matching path of the data object to be filtered; and determining a filtering requirement that the data object to be filtered meets. The techniques combine public description values and public description sub-paths based on a path dependency graph, reduce determinations in the filtering process and reduce the time of computation.
