Abstract： In recent years, there are such significant improvements on the performance and efficiency of big data technology and system. As it is widely applied in various fields, big data has empowered industrial intelligence, and is the key step into the intelligent stage of information society. Therefore, we are facing greater challenges nowadays, such as the paradox of data flooding and high-value data lacking, the complexity and uncertainty of big data analysis, and the difficulty to balance the data on sharing and circulation, and trustworthiness and security. Moreover, these challenges will not only promote the innovation and change of big data technology, but also develop and establish a new technology system. With respect to the requirements of new architecture, new paradigm, new model and security and trustworthiness, this study proposes to build a new big data analyzing and processing system stack, explore the new paradigm of extracting big data value, and outlook on the pioneer applications as the traction to a broad range of fields.

Abstract： The world is entering a new era of human-cyber-physical ternary computing with diverse intelligent applications over trillions of devices. This calls for a new type of cyberinfrastructure characterized by a planet-scale, high-goodput, low-entropy computing network, colloquially named Information Superbahn. This article highlights the vision of Information Superbahn, including fundamental requirements, key scientific problems, and a candidate system architecture. The goal of building the Information Superbahn is to natively support human#2;cyber-physical systems and low-entropy computing modes, to reduce the effects of systems disorder. Compared with existing network computing systems, such as Internet, cloud computing, big data and Internet of Things, Information Superbahn aims to achieving higher system goodput and application quality of service.

Abstract： RISC-Ⅴ has been obtained huge attentions and extensively invested over the past decade due to its exciting slogan that “Instruction Sets Want to be Free”. Based on RISC-Ⅴ, we are able to build a “human community with a shared future” in the CPU chip area, although thereare still many challenges. China should explore its capability to make more contributions in building the open-source chip ecosystem.

Abstract： Chip is the foundation of the modern information society. As the world is entering a new era of human-cyber-physical ternary computing, with diverse intelligent applications over trillions of devices, chip with specialized architecture will be heavily demanded in both numbers and types. However, chip design is very costly, which usually requires a long design cycle, complicated process, and high professional developers. Hence, there is a large gap between the need of tremendous chips and the high cost of chip design in the new era. This study proposes Chip Learning, a learning-based method to perform the entire chip design,including logic design, circuit design, and physical design. As an alternate to chip design, Chip Learning aims to remove the barrier of professional knowledge and experiences for effective chip design with a no-human-in-the-loop process in a short time.

Abstract： Self-reliance and self-strengthening at high level does not depend on a single technique, but on the formation of an advantageous national tech-system, so called “country-as-a-platform”. Information tech-system refers to the whole one that closely connects devices, components, complete machine, system software, middleware, and application software with a series of technical standards and intellectual property rights. We are entering the IT 3.0 era characterized by integration of human-cyber-physical world. The IT 3.0 era will certainly produce a new tech-system different from the IT 1.0 and IT 2.0 eras, which is a rare opportunity for China to build a self-reliance and self-strengthening tech-system. In the future, the information industry ecology will develop in the direction of domain-specific oriented and China’s advantages will be fully reflected in the future competition. The following principles should be paid attention to in the construction of information tech#2;system: (1) correctly deal with the dialectical and unified relationship between self-reliance and open cooperation. We should actively integrate into the global innovation network and make China a broad stage for global scientific and technological opening and cooperation. (2) Before revolutionary devices enter the market on a large scale, the hope of improving computer performance and energy efficiency mainly lies in the innovation of architecture. We should focus on the development of cross layer vertical optimization technology in various fields, and defeat the once mainstream general-purpose chips with acceleration chips and systems suitable for different scenarios. (3) Develop open source ecology and build a community of technological destiny. Open source is not only an effective way to win the strong with the weak and break the technology monopoly, but also an important way to build a self-reliance and self-strengthening tech-system in China. (4) Mainly develop domain specific industrial ecology. The information field has an important characteristic different from other fields: the new market is much larger than the old market. Large market means many innovation scenarios, and the future market of a subdivided field can form a large enough industrial ecology. Another feature of China is that there are many developers, we therefore have the natural advantage in development of domain-specific architecture (DSA). (5) Vigorously develop agile design and agile manufacturing. The cost of chip design is very high, which cause high professional threshold. In the era of ubiquitous interconnection, there is a sharp contradiction between the high demand for chips and the high cost of chip design. Agile design is the most effective way to deal with fragmented application scenarios. This paper briefly introduces eight articles on this special issue of “Build and Strengthen China’s Information Tech-system”. These articles focus on the choice of future technology direction and scientific research mode, which to a certain extent reflects the efforts and expectations of Chinese scientific and technological researchers to explore and establish a new information tech- system.

Abstract： [Objective] Explore the characteristics of emotional expression of "empty nest youth" and "non-empty nest youth" using Weibo data. [Methods] This study selected the "empty nest youth" group and the "non-empty nest youth" group from 1 million active users which are based on the activity status of Weibo users, and compared the differences in emotional expression between the two groups of users in the Weibo. [Results] From the results of independent sample t-test and two-way analysis of variance, it can be seen that the emotional expressions of "empty nest youth" group and "non-empty nest youth" are significantly different. According to regional and gender division, it can be found that there are also differences in emotional expression. [Limitations] The word frequency analysis is not completely equivalent to the emotion measured by the psychometric scale. Although the word frequency analysis based on the Weibo data provides an efficient analysis method, it cannot completely replace the strict psychological measurement. [Conclusions] The "empty nest" state affects emotional expression; "empty nest youth" tends to express inner emotions. " "
