Abstract

The invention provides a reviewer recommendation method based on tree structure representation, and the method comprises the steps: firstly constructing a reviewer tree, organizing information into a tree according to a hierarchical logic structure of data, and carrying out the feature representation of tree nodes; carrying out feature extraction of a tree structure, obtaining similar information of hierarchical nodes through clustering, obtaining supplemental information of the hierarchical nodes to superior nodes by constructing a local sensing reconstruction model, and finally reconstructing the superior nodes by combining result global weight and local weight with child nodes, wherein feature representation of a tree structure is finally obtained from bottom to top in the process; and finally, carrying out reviewer recommendation by calculating the similarity represented by tree structure features. Compared with an existing scheme, a better recommendation effect is obtained.

Description

technical field [0001] The invention belongs to the technical field of feature representation learning and recommendation systems, and in particular relates to a reviewer recommendation method based on tree structure representation. Background technique [0002] With the rapid development of information technology, scientific research information has also exploded. How to help scientific researchers quickly and efficiently find experts related to their own research fields has always attracted much attention. At present, domestic and foreign researches on scholars' expression are more concerned with the papers he publishes and the social network among reviewers, while the information of scholars' biographies and references of papers has not been well utilized. Therefore, how to integrate the multi-source information of reviewers, fully represent the characteristics of reviewers, and efficiently recommend reviewers has become a problem that needs to be solved urgently.
