From the perspective of the source of funds，At present, most scientific research is funded by public funds，The results obtained by the Institute should also be opened to the public for free。March 2018，The "Administrative Measures for Scientific Data" issued by the General Office of the State Council points out，"Scientific data formed by government budget funds shall be open as the normal state、The principle of not opening is the exception，Catalogs of scientific data resources organized by the competent department，Relevant directory and data should be connected to the national data sharing exchange platform，Open sharing for society and related departments，Unblocked Scientific Data Military and Civil Sharing Channel "。The Office of Science and Technology Policy bet365 live casino games (OSTP) also proposed in 2013，Non -secret scientific research data generated by all federal funds or partially funded by scientific research projects，Reserve not provided access to the public for free。Scientific data subsidized by public funds is open to obtain，Not only is it conducive to resource sharing，​​It is also conducive to strengthening social supervision of scientific research results，Containing the occurrence of scientific dislocation behaviors。

Regardless of the requirements for submission of academic journals，Or the sharing needs of scientific researchers，Open sharing of scientific data needs to be used as a platform，To achieve effective management of scientific data、Public sharing、Specific reference and publishing and spread。my country's scientific data sharing business started late，Related data opening work is subject to the requirements of foreign academic journals，Data storage and opening up also rely more on foreign data storage。To improve the service system of scientific and technological resource sharing，Promote the opening of science and technology resources to the society and sharing，my country established 20 national scientific data centers in 2019，Help to promote scientific data in related fields to gather to the national platform，Improve scientific data storage、Infrastructure required for management and safety。other，There are also public data storage sharing platforms such as "Science Data"，Provide data online storage、Long -term storage and acquisition、Share、Publishing and reference service。

　　Open data Promoting repeated scientific research

Open sharing of scientific data for other researchers to quote or reproduce experiments，helps to avoid unnecessary repeated experimental operations，Short the research cycle，Accelerate the research bet365 live casino games process in the entire field。Data in the field of information science has good scientific data open and shared basics，Various algorithm competitions provide the benchmark data set，If the benchmark data set of the visual recognition challenge (ILVRC) is iMagnett。2012，Alexnet obtained image classification and object recognition algorithm based on ImageNet in this event，The error rate is 10.8 percentage points lower than the second place，Famous in World War I.，Stir more use of convolutional neural networks and GPUs to accelerate the emergence of deep learning research。Public sharing and application of the benchmark data set，Driving related fields have made significant progress and breakthroughs。

Open sharing of scientific data can also effectively improve the academic influence of research results。For example，2016，A researcher of the Institute of Empty Information Innovation of the Chinese Academy of Sciences Qiu Yubao and others published "The Daily Modis of the Qinghai -Tibet Plateau Modis without Cloud Jet Snow Data" (DOI: 10.11922/SciencedB.55) obtained thousands of visits and multiple platforms、National Scientific Data Center reprint，Views have been among the best in scientific data banks。Related data also received a large number of active feedback from users at home and abroad，It is effectively used in the field of discipline。

Open sharing of scientific data is also open、Reasonable academic exchanges provide a basis。For example，"Sociology Research" 2019 6 journals published "Housing Marketization and Housing Equality -Research on CHIP and CFPS Data"，After the article was published, some readers conducted a copy of this article and publicized some questions。Subsequent，Original Author Wu Kaize on data processing、Model analysis results have a key response to readers' questions。The important Bet365 app download feature of this type of quantitative research is that it can be replicated。Because the papers in the controversy are used by the public data such，Therefore, professional readers can reappear this study，So as to open the academic exchange of sincerity，Further enhances the credibility of research。

　　Diversity of scientific data open sharing measures

Open and shared atmosphere of international scientific data is becoming increasingly mature。2015，International Science Council (ICSU)、International Partnership (IAP)、The School of Sciences (TWAS) and the International Council of International Social Science (ISSC)，The Open Data in A Big Data World Agreement was released at the International Science Council (this agreement believes that "open data" will improve the efficiency of public research、Productivity and creativity)，At the same time, the data that supports scientific papers can also provide the basis for scientific "self -correction"。"Center for Open Science" published the "Journal Transparency and Open Guide" for journal publishing，Requires the journal in the source reference、Data、code、Research materials、Research Design and Content Analysis、Research pre -registration and repeated verification and other aspects of transparent openness。Elsevier、Springer Nature、TAYLOR&Francis and Wiley have also formulated data sharing policies，Encourage the author to quote relevant scientific data，Provide data availability declaration，and store the data in a suitable data repository。

Domestic scientific data management is gradually standardized。At the national policy level，March 2018，The "Administrative Measures for Scientific Data" issued by the General Office of the State Council will be proposed，"The competent department and legal person unit should actively promote Bet365 app download scientific data publication and dissemination work，Support scientific researchers to sort out and publish clear property rights、Accurate and complete、Scientific data with high sharing value "，And required "Scientific data users should comply with relevant provisions of intellectual property rights，Published in the paper、Patent application、Symptoms and Publishing and other scientific data of the use and reference quoted "。In terms of journals，my country has data journals such as "Chinese Science Data" and "Journal of Global Change"，Another traditional academic journal specially set up data thesis columns。"China Surgery Magazine" released the "Notice on the Volunteer Submitted Manuscript Supporting the original Data" in 2017，Driven the manuscript once hired，Supporting data will be included in the management of national population and health scientific data sharing platforms at the same time as the article is published。

　　Practice of data open sharing concept Expand

Scientific data open sharing mode can be divided into three categories。1. Cooperation with professional scientific data storage，Carrying out a related publishing of scientific and technological papers and its supporting scientific data (data published by publications)。2. Independent data publishing is the release of data storage storage (not relying on the data of the publication)。3. Published in the form of data papers (published as data as the publication itself)。Where，The open sharing process of the first method is more flexible，can be in multiple forms、Embeds the submissions of the papers at multiple time nodes、review and publishing process。For example，You can submit a data set in the collection stage of the science and technology papers，Scientific data to participate in the entire thesis review Bet365 app download process with scientific and technological papers; you can also submit scientific data at the stage of the dissertation，Complete the review of the data set before the publication of science and technology papers、Processing, finishing and publishing work。

The method of sharing scientific data and papers has an independent reference、Independent logo、Independent measurement evaluation and many advantages in data sharing and data reuse。other，Entry of data from professional scientific data repository、Storage and safety management，It can make scientific data open and sharing have better persistence。

Scientific data storage storage sharing in scientific data、Help scientific research to improve the vital role in the process of repetitiveness。Scientific data storage reservoir enables scientific data to be discovered。For example，Provide data API、Unique identifiers and other services; well support the reuse of open data，Specify a clear data use license agreement for open shared data (such as the CC license agreement)，Provide metadata acquisition service with machine readability，Provide data specification quotation services; support the integrity and authenticity of open shared data; support data update operation and version management mechanism。

Now，Scientific Data Open Sharing as a high collaboration for scientific research、Open acquisition、Data sharing、Research on an important way to study transparent，It is helping people to solve the challenges brought by the duplicability of scientific research。my country has great potential in the open sharing of scientific data，Government management and scientific research have made unremitting efforts，and have achieved certain results。"Data Open Sharing" concept and development and progress of practice，It will depict a beautiful blueprint bet365 Play online games for the repeatable scientific research。
