Embodiment Construction
[0042] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments. The present invention selects the Cleaned Dump data set, which is the public data of the Bibsonomy website.
[0043] Extract the user label and resource label data in the data set to form the user label data set D 1, resource label dataset D 2 , the extraction process is as figure 2 shown. Select the feature vectors that can construct candidate tags for resources in the resource tag data set, including url URL information, description URL description information, titie book name, and description book description information. The dataset is described as D 2 ={(x i ,y i )|1≤i≤m}, where x i represents resources, y i Represents the tag added by the resource, where x i =[ulr, des_bm, title, des_bt] represents the 4-dimensional feature vector of resour...
