Embodiment
[0114] All the steps in this embodiment run on the ubuntu14.04 platform, use the python language, tensorflow1.2GPU version library, and conduct experiments on two data sets CiteULike-a and CiteULike-t in the field of academic paper recommendation.
[0115] The experimental configuration is: operating system Ubuntu 14.04, memory 32G, 4 TitansX graphics cards.
[0116] The experimental data is prepared as follows: The present invention uses two datasets, CiteULike-a and CiteULike-t, respectively organized by two research groups. Their statistics are shown in Table 1. Both datasets are compiled from the academic social networking site CiteULike. The site allows each researcher user to create their own personal online library of papers they are interested in, and each paper contains text information such as its title and abstract.
[0117] When constructing the "paper-user interaction" matrix, CiteULike-a only retains users who have collected more than 10 papers, while CiteULike...
