Abstract： [Purpose/significance] The purpose of this paper is to study the linked data model of publishing the NSTL’s research entity name authority data as linked data. After the name authority data is published as linked data, it can be reused as an open linked data set by other system or organization, and also can be better integrated with other linked data sets to improve data quality. In addition, it also provides a model building reference for other organizations to publish authority data as linked data. [Method/process] First, this paper analyzed and compared the data models used in the linked data publishing projects at home and abroad. It showed that the data models in the linked data publishing projects were mainly divided into two categories. Then, combined with the characteristics of NSTL name authority data, two forms of linked data models were designed. It compared the two models from the expression level of the NSTL’s data and the complexity of the models. The better one was selected. Finally, it used D2RQ as tool to publish the sample data as linked data. [Result/conclusion] The analysis found that the model with Schema.org as the core standard vocabulary has better performance. So it is more suitable as a linked data model for NSTL’s name authority data.

Abstract： [Purpose/significance] Aiming at problems of intelligent Q&A based on Q&A pairs such as low accuracy and resolution rate and poor user satisfaction, this paper constructs a knowledge graph (KG) ontology model that supports the realization of dynamic and accurate intelligent Q&A based on the knowledge graph. [Method/process] First, the paper analyzed the current problems and causes of intelligent question answering, and proposed a plan to build a knowledge graph to support intelligent question answering. Second, On the basis of existing ontology model construction methods, the paper proposed a multi-round loop method integrating multi-level data, which used the business data provided by the enterprises, user data and business system dynamic data as the data sources. And the core steps were to build a basic framework, improve the knowledge structure, and align three cycles of the knowledge structure. Finally, this paper took the domain of return and exchange as a case to describe the concrete steps of ontology model construction, from zero, added incrementally, and constructed ontology model of knowledge graph. [Result/conclusion] This paper applies the knowledge graph with the return ontology model as the schema layer in an intelligent Q&A system for testing. The evaluation results show that the accuracy rate increased by 50% and the precision rate increased by 300% after the return and exchange knowledge graph is online. So, the proposed ontology model construction method sorts out the complete and fine-grained domain knowledge structure from scattered domain knowledge, can provide accurate answers to users in intelligent Q&A, and can effectively solve the intelligent Q&A dilemma based on Q&A pairs.

Abstract： [Purpose/significance] Network information service platforms provide great convenience for citizens’ life, however, the problem of users’ personal information security risk is increasingly serious, thus identifying and preventing risks are vital to enhance the governance capacity of network space and promote modernization of the governance system in cyberspace. [Method/process] Through cluster analysis on privacy policies of 117 sample Apps, this paper found out potential risk types of users’ personal information security. [Result/conclusion] This paper illustrates that the ecological environment of network space consists of the small ecology of the third party in the process of network information service, the internal ecology of network information service platforms, and the external ecology of network information service platform industry groups. According to that, this paper puts forward effective paths of personal information security risk governance form aspects of specifying platform privacy policies, regulating internal control mechanism of platforms and the interaction mechanism with the third parties, as well as playing the main role of government governance.

Abstract： [Purpose/significance] Network information content governance has become an important part of national strategy and an important measure to build a cyber power. Identifying and deconstructing the risks of network information content security is an effective way to diagnose the key and difficult points of network information content governance. [Method/process] Combining literature investigation with the Regulations on Ecological Governance of Network Information Contents, this paper conducted research and carried out feature analysis of network information content security risks; With content analysis method, this paper made a quantitative analysis of the network information content governance incidents published by Cyberspace Administration of China in the past seven years; With social network analysis method, this paper analyzed the relationship between the elements related to the risks of network information content security in governance, and deconstructed scene elements. [Result/conclusion] This paper divides the risks of network information content security into 9 types, and analyzes the connotations and characterizations of each risk. The evolution trend of the risk is related to the development of network new media technology, unexpected public safety incidents and the changes of policies and regulations related to network governance. There are differences among the scene elements of different types of risk, such as the significantly low participation of information service platforms, and little attention to the network ideology risk or the cultural invasion risk. In terms of governance objects, this paper proposes that it is necessary to further subdivide the characteristics of network information content security risks, especially in establishing the risk assessment system of network information content security. In terms of governance subjects, the key point is clarifying the main responsibility of network information service platforms. In terms of fundamental governance principles, we need to focus on the network information content governance in the view of a holistic approach to national security.
