- Abstract
- Patent analysis has become important for management as it offers timely and valuable information to evaluate R&D performance and identify the prospects of patents. This study explores the scattering patterns of patent impact based on citations in 3 distinct technological areas, the liquid crystal, semiconductor, and drug technological areas, to identify the core patents in each area. The research follows the approach from Bradford's law, which equally divides total citations into 3 zones. While the result suggests that the scattering of patent citations corresponded with features of Bradford's law, the proportion of patents in the 3 zones did not match the proportion as proposed by the law. As a result, the study shows that the distributions of citations in all 3 areas were more concentrated than what Bradford's law proposed. The Groos (1967) droop was also presented by the scattering of patent citations, and the growth rate of cumulative citation decreased in the third zone.

- Abstract
- This study uses three bibliometric methods: direct citation, bibliographic coupling, and co-authorship analysis, to investigate interdisciplinary changes in library and information science (LIS) from 1978 to 2007. The results reveal that LIS researchers most frequently cite publications in their own discipline. In addition, half of all co-authors of LIS articles are affiliated with LIS-related institutes. The results confirm that the degree of interdisciplinarity within LIS has increased, particularly co-authorship. However, the study found sources of direct citations in LIS articles are widely distributed across 30 disciplines, but co-authors of LIS articles are distributed across only 25 disciplines. The degree of interdisciplinarity was found ranging from 0.61 to 0.82 with citation to references in all articles being the highest and that of co-authorship being the lowest. Percentages of contribution attributable to LIS show a decreasing tendency based on the results of direct citation and co-authorship analysis, but an increasing tendency based on those of bibliographic coupling analysis. Such differences indicate each of the three bibliometric methods has its strength and provides insights respectively for viewing various aspects of interdisciplinarity, suggesting the use of no single bibliometric method can reveal all aspects of interdisciplinarity due to its multifaceted nature.

- Abstract
- To explore the possible facilitative role of the Internet in the process of research collaboration, this study endeavored to systematically compare the phenomenon of co-authorship and the impacts of co-authorship between pre-web and post-web stages in the field of information systems. Three hypotheses were proposed in this study. First, research collaboration increases in the post-web stage relative to the pre-web stage. Second, research collaboration is positively related to research impact, operationally defined as the number of citations. Lastly, the positive relationship between research collaboration and research impact is stronger in the post-web stage than that in the pre-web stage. Articles published in the field of information systems in both time periods were collected to test the hypotheses. The empirical results strongly support H1 and H2, showing that co-authorship increases in the post-web stage, and positively correlates with citations received by information systems articles. The positive effects of interdisciplinary collaborations and collaborations among multiple authors are enhanced in the post-web stage, but such enhancement is not found for international collaboration. H3 is partially supported.

- Abstract
- The Internet has substantially increased the online accessibility of scholarly publications and allowed researchers to access relevant information efficiently across different journals and databases (Costa & Meadows, ). Because of online accessibility, academic researchers tend to read more, and reading has become more superficial (Olle & Borrego, ), such that information overload has become an important issue. Given this circumstance, how the Internet affects knowledge transfer, or, more specifically, the citation behavior of researchers, has become a recent focus of interest. This study assesses the effects of the Internet on citation patterns in terms of 4 characteristics of cited documents: topic relevance, author status, journal prestige, and age of references. This work hypothesizes that academic scholars cite more topically relevant articles, more articles written by lower status authors, articles published in less prestigious journals, and older articles with online accessibility. The current study also hypothesizes that researcher knowledge level moderates such Internet effects. We chose the "IT and Group" subject area and collected 241 documents published in the pre-web period (1991-1995) and 867 documents published in the web-prevalent period (2006-2010) in the Web of Science database. The references of these documents were analyzed to test the proposed hypotheses, which are significantly supported by the empirical results.
