As the construction of the Energy Internet has launched into a novel method, the dependence on energy and information networks has been greatly increased. The interaction of energy and information flow has become recurring, and the deep coupling of energy and information flow has been realized. As a result, security risk factors have increased substantially. Given that, this article from the perspective of energy and information flow, combined with the “Source-Grid-Load-Storage” coordination scenario of the energy Internet and the actual development needs of the information network, this article proposes a risk assessment for many security risks that threatens the stable construction of the energy Internet Index system and corresponding index analysis.
Named Entity Disambiguation (NED) refers to the task of resolving multiple named entity mentions in an input-text sequence to their correct references in a knowledge graph. We tackle NED problem by leveraging two novel objectives for pre-training framework, and propose a novel pre-training NED model. Especially, the proposed pre-training NED model consists of: (i) concept-enhanced pre-training, aiming at identifying valid lexical semantic relations with the concept semantic constraints derived from external resource Probase; and (ii) masked entity language model, aiming to train the contextualized embedding by predicting randomly masked entities based on words and non-masked entities in the given input-text. Therefore, the proposed pre-training NED model could merge the advantage of pre-training mechanism for generating contextualized embedding with the superiority of the lexical knowledge (e.g., concept knowledge emphasized here) for understanding language semantic. We conduct experiments on the CoNLL dataset and TAC dataset, and various datasets provided by GERBIL platform. The experimental results demonstrate that the proposed model achieves significantly higher performance than previous models. INDEX TERMS Named entity disambiguation, pre-training, lexical knowledge.
Mail transmission was not only the main function of information system, but also the main way of network virus and Trojan horse transmission, which has a key impact on the running state of information. In order to deal with the threats of network viruses and Trojans and improve the level of e-mail management, this paper studies the filtering of information system, and proposes a phishing e-mail filtering method based on Improved Bayesian model. MATLAB simulation results show that the consistency p between the amount of data sent by e-mail and the amount received is good, the consistency rate reached 92.3%. the data security level is 95%, encryption proportion / data proportion ratio under Bayesian optimization are higher than those of unfiltered method,which up to 97.2%. Therefore, the Bayesian optimization model constructed in this paper can meet the needs of phishing email filtering in information communication at this stage.
This paper presents a new algorithm based on the theory of mutual information and information geometry. This algorithm places emphasis on adaptive mutual information estimation and maximum likelihood estimation. With the theory of information geometry, we adjust the mutual information along the geodesic line. Finally, we evaluate our proposal using empirical datasets that are dedicated for classification and regression. The results show that our algorithm contributes to a significant improvement over existing methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
