DGPort: A Web Portal for Digital GovernmentYin, C.Q.; Nickels, L.D.; Chen, C.Z.; Ng, Gavin; Chen, Hsinchun (2003)This paper provides a summary of the initial development of a Web portal for the digital government domain. Information retrieval techniques commonly used to find information on the Internet are discussed along with the problems associated with these techniques that led to the development of the Digital Government Web portal (DGPort). We also discuss the advantages that DGPort could have for researchers in the digital government domain as well as the value-added features that this portal provides. Future evaluation plans for the portal are also described.
Genescene: Biomedical Text And Data MiningLeroy, Gondy; Chen, Hsinchun; Martinez, Jesse D.; Eggers, Shauna; Falsey, Ryan R.; Kislin, Kerri L.; Huang, Zan; Li, Jiexun; Xu, Jie; McDonald, Daniel M.; et al. (Wiley Periodicals, Inc, 2005)To access the content of digital texts efficiently, it is necessary to provide more sophisticated access than keyword based searching. Genescene provides biomedical researchers with research findings and background relations automatically extracted from text and experimental data. These provide a more detailed overview of the information available. The extracted relations were evaluated by qualified researchers and are precise. A qualitative ongoing evaluation of the current online interface indicates that this method to search the literature is more useful and efficient than keyword based searching.
Longitudinal patent analysis for nanoscale science and engineering: Country, institution and technology fieldHuang, Zan; Chen, Hsinchun; Yip, Alan; Ng, Gavin; Guo, Fei; Chen, Zhi-Kai; Roco, Mihail C. (Kluwer, 2003)Nanoscale science and engineering (NSE) and related areas have seen rapid growth in recent years. The speed and scope of development in the field have made it essential for researchers to be informed on the progress across different laboratories, companies, industries and countries. In this project, we experimented with several analysis and visualization techniques on NSE-related United States patent documents to support various knowledge tasks. This paper presents results on the basic analysis of nanotechnology patents between 1976 and 2002, content map analysis and citation network analysis. The data have been obtained on individual countries, institutions and technology fields. The top 10 countries with the largest number of nanotechnology patents are the United States, Japan, France, the United Kingdom, Taiwan, Korea, the Netherlands, Switzerland, Italy and Australia. The fastest growth in the last 5 years has been in chemical and pharmaceutical fields, followed by semiconductor devices. The results demonstrate potential of information-based discovery and visualization technologies to capture knowledge regarding nanotechnology performance, transfer of knowledge and trends of development through analyzing the patent documents.
