- 摘要：Existing data management techniques and their drawbacks were introduced.A novel model called self-governing openness of data was presented,and the details in using the technique were also illustrated.Self-governing openness of data would be a basic path for realizing the openness of data.Meanwhile,it should be an applicable approach for the openness and sharing of government data,the transaction of enterprise and personal data,and the realization of national data sovereignty.关键词：open data;data sharing;self-governing openness of data;big data606|919|0更新时间：2018-03-15
- 摘要：In today’s world,the governance of the government becomes more and more dependent on the effective use and management of data resources,and building of data sharing mechanism is the most difficult challenges.To solve the challenge,the concept of self-governing openness of data autonomy was proposed,and the possibility of allowing the relevant departments of the government independently promoting the open sharing of data resources after clearly defining the ownership and necessary use-maintenance costs of the data resources was explored.From the existing practice and international comparative experience,the construction of an open government based on self-governing openness of data autonomy may become a practical path adapted to Chinese characteristics.It not only serves China’s reform and open up,but also can make corresponding important contribution to the world.关键词：self-governing openness of data;data sharing;E-government;governance402|1120|0更新时间：2018-03-15
- 摘要：Self-governing openness of data makes that users can download or upload data to their applications to use data.However,there exist two key issues.Firstly,how to know the contents of the data.Secondly,how to organize data to fit the users’ applications feasibly and manage data conveniently.A novel data model namely data box was presented,the elements of data box and operating system structure were introduced,and the implementation of the data model was illustrated.关键词：open data;data sharing;self-governing openness of data;data model561|1123|0更新时间：2018-03-15
- 摘要：Self-governing openness of data is a new form of the openness of data,which enables protecting interests of data owners.Self-governing openness of data requires full supports of software development and runtime environment in the fields of requirements description,development and debugging,and monitoring applications execution.An overall design of the software development and runtime environment for self-governed openness of data was presented,and the whole application development process for self-governing openness of data that supports software behavior monitoring and control was illustrated.Full life-cycle management of data in self-governing openness of data was enabled and the feasibility of the software development and runtime infrastructure for self-governing openness of data was shown.关键词：open data;self-governing openness of data;software development environment;software runtime environment;software behavior monitoring and control375|581|0更新时间：2018-03-15
- 摘要：The openness of data is very important for improving the application value of data resource.However,due to the consideration of privacy preservation,data should be open under supervision.That is,data should be in the mode of selfgoverning openness.For challenges that self-governing openness of data may bring,a possible system framework for the privacy preservation of a data box was presented.The system framework carries out the privacy disclosure risk evaluation for the data usage declaration of a data user,and then determines whether the corresponding data usage request can be authorized or not on the basis of evaluation results,and thus supports the implementation of self-governing openness of data.关键词：data management;self-governing openness of data;privacy preservation330|450|0更新时间：2018-03-15
- 摘要：Data box is the basic data unit opened to the data users in self-governing openness of data,so the prevention for the degradation of data scarcity and the disclosure of privacy is mainly aimed at the data box.A data box may contain photos,videos,text and structured data,etc.The traditional data encryption technology cannot be effectively applied.The requirement of data encryption for data box and the challenges of traditional data encryption technologies were analyzed,and the prospect of new encryption technologies for self-governing openness of data was discussed.关键词：self-governing openness of data;searchable symmetric encryption;property-preserving encryption;property-revealing encryption;homomorphic encryption;oblivious random access memory417|1079|0更新时间：2018-03-15
- 摘要：Asystemic solution for the application construction of self-governing openness of data based on the new data management pattern of self-governing openness of data was proposed.The whole framework,system functions and interfaces of the solution were provided.Then the key points about logical data organization,security requirements description and query requirements description technologies were designed and investigated for the data provider and data consumer,respectively.Finally,self-governing openness of data practices in the field of medical was discussed,and the framework of tiered diagnosis and treatment system application by using the proposed technologies was given.关键词：big data;self-governing openness of data;ogical data organization;requirement interface478|663|0更新时间：2018-03-15

- 摘要：To overcome the problem in which public meteorological services are rarely optimized for personalization,a recommendation method incorporating improved association rules and collaborative filtering was presented.First,FPGrowth algorithm was applied on pre-processed Web log data to generate association rules.Meanwhile,a customized collaborative filtering algorithm was used to calculate pairwise similarities between meteorological products based on users' browsing records.A total of five experiments were conducted.The experimental results show that the rules are relatively accurate for precipitation and haze weather,because pairwise similarities between meteorological products which are calculated by the proposed algorithm could reduce the total number of invalid or irrelevant association rules by 10%.关键词：intelligent recommendation;association rule;Web log;public meteorological service;parallel computing;similarity;collaborative filtering641|689|0更新时间：2018-03-15
