自媒体时代的消息传播问题分析

摘要

本文针对自媒体平台上信息传播过程问题，选择合适的自媒体平台和信息建立一系列相应的模型。文中通过类比生物学中传播病的传播方式和物种增长的特点，分别建立改进的SIR传播模型、关联信息相互作用的IDM模型等。然后使用MATLEB，R软件，通过具体数据，定量地对模型进行仿真模拟，探究出不同类型在同一自媒体和相同类型在不同自媒体中传播过程的差异，并根据建立的相关模型，给自媒体平台管理提出意见。

针对问题一，建立SIR传播模型，用以研究信息在自媒体平台上传播过程。首先，选取很具有代表性的自媒体平台微博，作为信息发布的平台，并对其信息传播特点进行分析。然后利用物理学中平均场近似法，把微博网络的节点信息交互作用平均化，并把微博的全部用户看做一个种群，把信息在微博用户中的传播看做病毒在种群中的传播，把各个用户看做节点，最后在此基础上，建立SIR传染模型，达到合理对信息在自媒体平台传播过程的模拟。

针对问题二，建立关联信息之间相互作用的IDM模型，解决两个相关联信息之间的泛化竞争传播问题。根据SIR传播模型的基础上，把两个相互关联的信息在自媒体中的传播，分解为在子网络中的子让增长过程和不同子网络间的扩散问题。对Fisher模型和Diffusive Logistic模型进行改进，建立关联信息之间相互作用的IDM模型，得出两个相关联信息之间相互促进或抑制的条件，进而得出关联信息出现后，原信息的传播变化。

针对问题三，在SIR传播模型的基础上，通过采集历史具体数据，定量的对不同类型的信息在相同自媒体平台和相同信息在不同自媒体平台中传播过程进行模拟，通过可视化的结果，具体分析出存在的相似与差异，并对问题一模型进行定量的验证。

针对问题四，在SIR传模型播关联信息相互的IDM的模型以及问题三定量的验证的基础上，在自媒体管理的管理中，对于不良信息，管者不能听之任之，应做到在关键节点，进行“疏”，“堵”有度，科学控管。

In this paper, aiming at the process of information dissemination from the media platform, we choose a suitable series of media platforms and informatio n to establish a series of corresponding models. In this paper, the improved SI R propagation model and the IDM model of the interaction of the information are established by the propagation mode of the transmission disease and the ch aracteristics of the species growth in the analogy biology. Then, we use MATL EB, R software to simulate the model quantitatively through the concrete data, and find out the difference of different types in the same media and the same type of propagation in different media. According to the relevant model, Platfo rm management.

For the problem one, the SIR propagation model is established to study th e propagation of information on the media platform. First of all, select a very representative from the media platform microblogging, as a platform for inform ation dissemination, and its information dissemination characteristics of the anal ysis. And then use the average field approximation in physics, the microbloggi ng network node information interaction is averaged, and the microblogging of all users as a population, the information in the microblogging users as the spr ead of the virus in the population Communication, the user as a node, and fin ally on this basis, the establishment of SIR infection model, to achieve a reaso nable information in the media platform from the process of simulation.

In order to solve the problem, the IDM model of the interaction between the related information is established, and the problem of generalized competiti on propagation between the two related information is solved. the diffusion pro cess in the sub - network and the diffusion between different sub - networks. The Fisher model and the Diffusive Logistic model are improved to establish t he IDM model of the interaction between the related information, and the cond itions of mutual promotion or suppression between the two related information are obtained. Then, after the occurrence of the related information, the propaga tion of the original information The

Based on the SIR propagation model, the data of different types of inform ation are simulated in the same media platform and the same information in di fferent media platforms by collecting the historical data. Through the visualizati on results, Analyzes the existing similarities and differences, and quantifies the problem-model quantitatively.

In the case of the management of the media management, for the bad inf ormation, the supervisor can not let it be, and should be done at the key nod e, and in the case of the IDM model of the SIR transmission model, To carry out "sparse", "blocking" a degree, scientific control.
