基于位置的机构合作网络构建方法研究

Construction of Location-based Institutional Cooperation Networks

机构合作是合作网络中观层面的合作,机构合作网络可以反映科研机构间的合作关系。机构合作网络多采用人工处理搭配工具进行构建,缺乏对空间数据的有效支持、生成的全局矩阵无法重复利用。设计一种基于位置的机构合作网络构建方法,利用基于位置的实体链接技术以及网络加权模型实现了机构合作网络的动态构建:基于机构位置的聚类法与同机构下作者唯一的策略解决了实体间共指与歧义问题;网络加权模型实现了机构合作网络的动态构建,便于增量更新、反映了合作关系的强度,使得机构合作网络更具科学性。实验证明,该方法可有效提高机构合作网络构建的效率和科学性。

The institutional cooperation is about meso scale,which depicts the scientific cooperation between different institutions.It is usually constructed by manually processing and matching tools,which provides weak supports for spatial data.In addition,the constructed global matrix could not be reused.This paper proposes a method to build an institutional cooperation network based on location.The location-based entity link technology and network weighting model are involved to dynamically construct an institutional cooperation network.A clustering method based on institution location and the″first author″strategy are developed to solve the problems of co-referencing and ambiguity between entities.A weighted network model is built to dynamically construct the institution cooperation network,realize incremental update and reflect cooperation intensity.Experimental results show that this approach helps to improve the efficiency and reasonability of construction of institutional cooperation networks.
