This revolution will be bi-directional: new understanding of human intelligence through brain science will yield a new generation of Web intelligence research and development, and Web intelligence portal techniques will provide a powerful new platform for brain science. The ultimate goal is to establish the foundation of WI towards human-level Web intelligence. In this talk, we investigate how to make such a study successfully.展开更多

This paper describes a practice of a medical library in providing online access to health information for the general public.Design/methodology/approach: A four-step workflow is developed to integrate and disseminate heterogeneous health information from medical associations. First, a raw data repository is developed to manage the original submissions from information providers.Second, each document in the raw data repository is represented in a standardized XML schema. Third, the medical terms are identified and manually annotated, enriching the semantics of health information. Lastly, all the semantically enriched XML documents are converted to HTMLs for online dissemination.Findings: A health information website, CHealth, was developed for Chinese speakers. It provides free online access for all without any login or IP constrains. CHealth is available at www.chealth.org.cn.Research limitations: The current workflow is time-consuming and labor-intensive due to the lack of information submission/exchange standard and commonly agreed-on consumer health terminology in Chinese.Originality/value: In this work, the target audience of the medical library has been extended from traditional academic/professional to the general public. Methodologies in library sciences have been combined with those in consumer health informatics in CHealth development.展开更多

We used the social capital theory to analyze the interviewees＇ record.Findings： In urban communities, social capital is the most important factor for children （aged 6 to 12） in their ICT use. Our findings indicate that children in families with higher levels of social capital, such as internal resources, family income, parent educational backgrounds and parents＇ social network, have more-highly developed ICT skills. Personal motivation and obstacles, such as lack of access to computers on a regular basis, also have an impact on children＇s ICT use. External social capital, including schools, libraries, and public service institutes, have little impact on children＇s ICT use, if not combined with internal social capital factors.Research limitations： Our research samples were collected from two communities within the same city, which may influence the generalization of this research result.Originality/value： To explore the social capital＇s influence on children＇s ICT use, we used field observation for ICT use of children aged 6 to 12 in urban communities in China, and studied the children＇s ICT behavior from the perspective of internal and external social capital.展开更多

However, the refining industry is suffering some challenges, such as severe overcapacity at present, and has entered a new economic normal, in which the technological progress develops rapidly, the demand for green and low-carbon development is stricter, the market competition is increasingly fiercer and the profit margins are gradually narrowing. In such a situation, informatization and its new technologies are driving the significant reforming of manufacturing patterns, marketing patterns, management and decision-making patterns. Intelligent development is the inevitable choice for the transformation and upgrading of oil refining and petrochemical industry. It is suggested that the intelligent evaluating model and method should be adopted to enterprise’s intelligentializing transformation and upgrading by laying a solid foundation of digital refinery and implemenation of digital upgrading.展开更多

The broadband business platform put out by China Netcom provides new generation of integrated ICT services which focus on service and would be rented to customers. Broadband business platform could satisfy varieties of informatization demands made by small and medium enterprises such as low investment,fast reaction,individuation and security. It could effectively assist small and medium enterprises to achieve informatization.

文摘Purpose:The research aims to investigate the capabilities of the Chinese independent libraries in providing service based on information and communications technologies(ICTs).Design/methodology/approach:Questionnaires were distributed to 140 Chinese independent libraries all over China.Data analysis was based on 114 valid questionnaires retrieved.Findings:The Chinese independent libraries’ directors had a low level of competency in the use of computers.Among them,the old people are faced with more difficulties in computer use than the young people.About 55%of independent libraries own computers,but only43%of them offer Internet connections.Most libraries pay less than 1,000 Yuan annually for the Internet access and the Internet access fee accounts for about 5%of library directors’ annual household income on average.With a limited number of computers,it is challenging for independent libraries to provide electronic reading service.However,to their users,they are playing the same important role as public libraries in ICT-based community service.Research limitations:Independent libraries that do not have an Internet website may not be included in our sample.In addition,missing responses and some inaccurate data in annual household income may affect our analysis result.Practical implications:Governments or non-government organizations should pay more attention to independent libraries’ informatization development and provide computer training for librarians,because independent libraries are playing an important role in community information communication.Originality/value:As there is so little related research published,the data collected in this survey provides a valuable snapshot of the Chinese independent libraries’ situation in providing ICT-based service.
文摘This paper makes a comprehensive statistical analysis of the papers published in recent years on the development of China's archives informatization from the aspects of the quantity,research focuses and approaches and thematic contents.In addition,it summarizes the current research situation in this field in general.
