Embodiment Construction

[0025] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

[0026] This embodiment discloses a data recommendation method based on citation network community discovery, such as figure 1 shown, including the following steps:

[0027] (1) First build a citation association network model, and then through the subsequent steps (2) to (4), input the data sets, authors, and papers that meet the specific relationship into the model, and output the recommendation results.

[0028] It should be pointed out that building a model is beneficial to data processing, but it is not a necessary means. Without building the model, the representation of data sets, papers, and author relationships and data recommendation can still be realized through the following steps. Building a model is only It is an implementation mode and should be...

Abstract

The invention provides a data recommendation method based on citation network community discovery, and the method comprises the following steps: constructing a citation network based on the cooperation relation between authors and the co-citation and coupling relation between papers; for the citation network, discovering a community network with similar or related research contents by utilizing amodular Louvain algorithm; based on the similarity between the paper and the data set, establishing association between the data set and the community network; and superposing and de-duplicating the paper nodes in the community network associated with the data set, and then performing data recommendation.

Description

technical field [0001] The invention relates to technical fields such as citation network, community discovery, similarity measurement, etc., and proposes a data recommendation method based on citation network community discovery. Background technique [0002] Scientific data is the input and output of scientific research activities and the core driving factor of scientific and technological innovation. The latest report "Data Age 2025" by the International Data Corporation (IDC) points out that the amount of global informatization data is rapidly growing at a rate of doubling every two years, and by 2020 the global informatization data storage volume will reach 47ZB. However, only 3% of potentially valuable data in the world has been developed and utilized, and even less data has undergone in-depth analysis and mining. Through further data statistical analysis of the Data Citation Index (DCI), it was found that by the end of 2018, only 11.83% of the data sets included in t...
