With the advent of the "Internet +"era, various network media have developed rapidly, and network communication methods have emerged one after another. The development of social networks has further expanded the environment for public opinion dissemination. Therefore, the study of the psycho-logical factors of network users' dissemination of public opinions on the basis of new social networks has become a research hotspot in the field of cyberspace security. By analyzing the characteristics of the representative Weibo social network platforms in China, this paper summarizes classic dissemination mode of information in social networks. Based on the existing user information behavior theories and classic user information behavior models, the study analyses the factors that affect the information dissemination behavior of network users. Finally, we make an outlook on the network public opinion under the new situation. Our study is of great significance for social platform information construction, user information acquisition, and network public opinion management under the new Internet situation. © 2022 IEEE.

Most existing multimodal named entity recognition (MNEr) methods cannot align image and text well, and fail to effectively fuse image-text semantic information, leading to suboptimal MNEr accuracy. To this end, this paper proposes a novel named entity recognition model based on Contrastive Learning and Multimodal Semantic Interaction (named CLMSI). Specifically, to narrow the semantic gap between image-text modalities, making semantically similar image-text representations closer and pushing dissimilar ones further apart, we propose a contrastive learning-based cross-modal alignment method. Moreover, to integrate multimodal information effectively and filter out the noise introduced by image features as thoroughly as possible, we propose to incorporate image descriptions as additional features to enrich the multimodal representation and to reduce the semantic bias of the image information. Extensive experiments conducted on two MNEr benchmark datasets, Twitter-2015 and Twitter-2017, demonstrate the superiority of the proposed method. Further ablation studies and case analyses also affirm the efficacy of CLMSI. © 2024 IEEE.

Network virtualization has been a particularly important driving force behind the development of NGN. Finding effective ways to control self-adapting virtual networks has become a research hot spot. This paper tries to find an efficient way in combining dynamic resource sensing with traffic character and requirements in virtual network, based on that an intelligent cognition based virtual network resources management model has been put forward. We design a network topology view by coloring network topology matrix with current resources model. We present an intelligent virtual resource management mechanism based on the proposed network topology view. Experiment results illustrate that the proposed mechanism can improve VN capacity by automatic resource adjust-ment, which can obtain high utilization of VN resources without increasing computational expenses.

The next generation of wireless technology, 6G, will likely incorporate advanced technologies such as extremely large-scale antenna arrays (ELAA) and millimeter wave (mmWave) communication. These cutting-edge features have the potential to revolutionize the way we communicate wirelessly, near-field communication (NFC) can not be ignored in future 6G mobile networks. Compared to far-field communication, the waves that propagate in the near-field region have a spherical wavefront. By utilizing the time agile of dMA and the correlation between near-field guidance vectors, we propose a novel channel estimation algorithm. Compared with the classic two-dimensional (2d) multiple signal classifier (MUSIC) algorithm, this algorithm effectively reduces computational complexity and ensures estimation accuracy. Simulation results show that the proposed channel estimation scheme achieves the expected results. © 2023 IEEE.

Cross-Site Scripting (XSS) vulnerabilities continue to pose a formidable challenge in the realm of web application security due to their prevalence. despite the development of various defense mechanisms, including input validation techniques and code differentiation strategies, these solutions have struggled to achieve broad adoption in real-world environments due to persistent issues such as unreliable detection, high computational overhead, scalability limitations, and compatibility concerns. This paper introduces a novel managed proxy-based framework for XSS defense, positioned strategically between the web browser and the web server. This framework employs a tag-based XSS protection mechanism alongside a defense-in-depth strategy, providing robust protection not only against XSS attacks but also against other web threats. Furthermore, the framework integrates advanced web front-end hardening techniques to significantly complicate the exploitation of potential vulnerabilities. Comprehensive practical evaluations indicate that the proposed framework is both flexible and effective, demonstrating outstanding performance across multiple dimensions.
