摘 要: | 考虑到用户之间的好友关系存在多种类型,且不同类型的好友关系信息传播偏好不同,提出了一种多关系类型社交网络信息传播模型,并建立了信息传播的动力学方程.在该模型中,用户根据自身的传播偏好决定是否分享或传播信息,并根据信息传播偏好主动选择可能的好友关系分享或传播信息.数据仿真结果表明:在多关系类型社交网络中,信息的传播范围和信息在网络中持续的时间与信息的特征有关;信息通过多种类型的好友关系传播能够有效提高信息的传播范围和传播速度.该模型与现实社交网络中信息传播的规律具有一致性,是一种有效的社交网络信息传播模型.

Abstract: | Considering the fact that different types of social relationships have different information propagation preference,we present a new social network information propagation model and set up dynamic equations for it.In our model,user nodes could share or propagate information according to their own preferences,and select feasible social relationships according to information preferences.The model reflects the facts that the propagation scope and duration of the information are related to its features,and the propagation speed and scope will increase if the information be propagated through multi types of relationships. |

Keywords: | social network service propagation model dynamic equations multi types of relationships |
