Abstract： [Purpose/significance] The fragmented and unstructured information of the epidemic brings challenges to emergency decision-making. To support the digitization of emergency decision-making and to promote intelligent emergency management, combining natural language processing and event ontology to realize the automation of epidemic information management and knowledge representation. [Method/process] An automatic construction strategy of domain ontology knowledge base based on web crawler, natural language processing, and event ontology was proposed. First, web crawlers and natural language processing were used for information collection and automatic extraction of event elements, and an epidemic event ontology model was built on this basis. Then, the algorithms for the ontology construction and update were designed, and the automatic construction and expansion for the event ontology was completed by them. [Result/conclusion] The results show that the proposed strategy has the feasibility of dynamic management and automatic update of epidemic information, and event ontology can describe events effectively and create conditions for knowledge expansion. This study also provides a reference for the research and practice of emergency decision-making.

Abstract： [Purpose/significance] Think tanks research in the big data environment aims at collecting, processing, analyzing, and digging out the logical rules contained in the massive information effectively, and representing large amounts of irregular data by visualization methods, which is a hot topic of research on think tanks. [Method/process] This article started with analyzing the current research status of think tanks and the big data visualization at home and abroad, and related theories of think tanks research methods based on big data visualization were sorted out. The application and innovation of big data visualization methods in supporting think tanks research were analyzed, and CiteSpaceⅡ software was used to analyze the research status of think tanks research in China. [Result/conclusion] The results show that the research methods of think tanks in China were relatively simple at present, and big data visualization research has two features: multi-disciplinary and multi-industry. Think tanks research methods based on big data visualization have developed rapidly, including techniques of the massive data process, the visualization algorithm, the graphic visualization, the human-computer interaction, the distributed processing and so on, which can support the big data visualization analysis in think tanks research. The application of big data visualization analysis in think tanks research can help think tanks process data efficiently, make decisions scientifically and accurately, visualize complex graphics, simplify complex problems, enhance users’ interaction well, agglomerate and share resources, and enhance their role and influence in the application research of think tanks.

Abstract： [Purpose/significance] The think tank financing mode is a decisive factor for its sustainable development. [Method/process] This paper analyzes the financing modes of six international famous think tanks and summarizes their financing modes and each proportion, the premise conditions and scopes of application. It raises some countermeasures in financing mechanism for the new think tanks with Chinese characteristics with references to the experience from foreign think tanks. [Result/conclusion] This paper finds five mainly financing modes, namely, government funding, social donations, market operation income, PPP mode and research project funding. It designs a multi-category, multi-channel and multi-level financing system and a Chinese think tank financing operation mode based on PPP and entrusted projects. It also suggests that the think tank should keep independence from the government, improve the legal policy of the donation tax, manage the financial risks so as to provide some inspirations for the new think tank with Chinese characteristics.
