摘要
[目的/意义]基于熵理论构建虚拟学术社区的熵流指标体系,通过测评系统有序度判定虚拟学术社区健康状态,并预测运行趋势,根据实验结果为虚拟学术社区系统有序发展提供可行策略,助力学术交流进步。[方法/过程]界定虚拟学术社区正负熵概念并构建正熵流和负熵流的指标体系后,选择科学网为研究样本,借助于转义的Brusselator模型判定科学网是否成为耗散结构,继而利用正熵值和负熵值计算系统有序度并对其运行状态进行讨论。[结果/讨论]科学网目前虽未达到耗散结构,但未来成为耗散结构的可能性极大,为使其可以从无序发展到有序,进而从低级有序发展到高级有序,提高科学网成员情感参与的投入性和虚拟学术社区行业竞争的规范性等应成为科学网改进的主要着力点。
[Purpose/Significance]Based on the entropy theory,the entropy flow index system of virtual academic community is constructed.By evaluating the order degree of the virtual academic community system,the status of the community is judged and the running trend is predicted.According to the experimental results,the feasible development strategy of the virtual academic community system is provided to strengthen the exchange of academic information.[Method/Process]After defining the positive and negative entropy concepts of the community and constructing the corresponding index system,Science Net was selected as the research sample,and the Brusselator model was used to determine whether Science Net become a dissipative structure.And then the entropy was used to calculate the order degree of the system in order to discuss its operating state.[Result/Conclusion]Although Science Net currently does not reach the dissipative structure,it is very likely that it will become a dissipative structure in the future.In order to enable it to develop from disorder to order,and then from low-level to high-order,strengthening the input of the emotional participation of members of Science Net and improving the standardization of industry competition in the virtual academic community should be the main focus of the improvement of Science Net.
