12. The apparatus according to claim 8 , further comprising: a second acquisition module, configured to acquire a confidence value that is determined when the predetermined classifier classifies the object; and a categorizing module, configured to: when the confidence value is greater than a predetermined confidence threshold, categorize the object corresponding to the confidence value as a type determined by the predetermined classifier.
8. An apparatus for classifying an object based on a social networking service, comprising: a storage apparatus; one or more processors; and one or more program modules, stored in the storage apparatus and executed by the one or more processors, the one or more program modules comprising: a first acquisition module, configured to acquire feature information of an object, the feature information comprising multiple segmented words; a logical operation module, configured to compute a semantic vector of the feature information, the semantic vector being used to reflect a relevancy feature when the segmented words exist in the feature information simultaneously; a classifying module, configured to input the semantic vector of the feature information of the object to a predetermined classifier, to obtain an initial category of the object after the object is classified; a first determining module, configured to determine, for each object by using a semantic vector of feature information of the object, a predetermined number of similar objects corresponding to the object; a formation module, configured to form an object pair by using the object and each of the similar objects; a construction module, configured to construct a bipartite graph by using the object pair formed by the formation module and a correspondence between a group and each user in the group; and a clustering module, configured to cluster an object in the bipartite graph by using a topic modeling algorithm, wherein the bipartite graph at least comprises a correspondence formed by a first element and a second element; and when the first element in the correspondence is a group, the second element is a user in the group or a group that is in a same object pair of the group; or, when the first element in the correspondence is a user, the second element is a user that is in a same object pair of the user.
