In this paper, analysis is made on the roles of different participants in data curation, including the government, scientific research institutes and researchers, IT and network centers, data centers and STI agencies, to define their specific functions in data curation. It is pointed out that due to the influence of the “social stereotype”, STI agencies engaged in data curation is taken for granted...
Along with the wildly use of information technology in people's production and daily life, our traditional understanding of city and urban space also changed. This change will eventually cause the deconstruction of urban space. This paper discuss some new space viewpoints that appear under the influence of information technology such as the disappearance of the distance, emergence of new border, mixed-function...
Research of constructing folksonomy in online social bookmarking system has attracted much attention recently. In this paper, we analyzed problems of constructing methods based on tag co-occurrence and proposed an entropy-based method to measure relationship of tag. Furthermore, a adjust threshold algorithm is proposed. Finally, comprehensive experiments are conducted and the result show our method...
Del.icio.us and diggo are very popular online bookmarking system, in this paper, different characterizes of two systems are detail analyzed. An entropy-based method to measure relationship of tag is proposed. Comprehensive experiments are conducted and the result show our method can effectively construct folksonomy.
Aimed at the limitations in previous research about integrating systems depending on a special field over last ten years, the paper proposes a general integrating platform which can be used in a variety of applications. In general, integrating systems suffer from performance bottlenecks due to network overhead. In order to address this problem, we introduce semantic caching mechanisms to reduce the...
