Embodiment

[0077] combine figure 1 , a method for discovering scientific research cooperation groups based on density clustering in the present invention, comprising the following steps:

[0078] Step 1, import batch paper data;

[0079] Step 2, preprocessing the paper data and extracting expert cooperation information;

[0080] Step 3, use the expert cooperation information to construct the expert cooperation relationship network, and use the Dijkstra algorithm to calculate the shortest path between experts, as follows:

[0081] Step 3.1. According to the author list information of the paper, use the author as a node, connect the authors who co-authored the paper with an edge, and use the reciprocal of the number of co-authored papers as the weight of the edge to construct an undirected weighted graph G(V,E) of expert cooperation information , the weight w of the edge between node i and node j ij Obtained by the following formula:

[0082]

[0083] Among them, V represents the po...

Abstract

The invention discloses a scientific research cooperation group discovery method based on density clustering. The method comprises the following steps: importing batch paper data, and taking the batch paper data as a training set; preprocessing the paper data, and extracting expert cooperation information, namely an expert name set under the same paper; constructing an expert cooperation relationship network by utilizing expert cooperation information, and calculating a shortest path between experts by utilizing a Dijkstra algorithm; constructing an expert cooperation epsilon field of each expert by using the shortest path between the experts, wherein epsilon represents the radius of the field; determining core experts by using the number of the experts in the expert cooperation epsilon field, and constructing a core expert set; and obtaining all cooperation group clusters in the expert cooperation network according to the core expert set. According to the method, the expert cooperation team and the core expert in the given thesis set can be quickly found, and effective support is provided for subsequent literature metering.

Description

technical field [0001] The invention relates to the field of cooperative group discovery, in particular to a method for discovering scientific research cooperative groups based on density clustering. Background technique [0002] Scientific research collaboration refers to the labor form in which individual researchers, individuals and groups, groups and groups cooperate with each other according to the plan to complete the same scientific research task. Scientific research is a complex and arduous group labor, and the interaction between people in scientific research activities directly affects the completion of scientific research collaboration and scientific research plans. For a long time in the past, scientific research was in a relatively scattered and unorganized state. Scientific research was "free research" conducted by individuals, and scientific research was mainly completed by those "masters" and "inventors". [0003] With the deepening of modern scientific rese...
