1Luo, P. ; Chen, K. ; Wu, C. ; Li, Y.: Exploring the social influence of multichannel access in an online health community.
In: Journal of the Association for Information Science and Technology. 69(2018) no.1, S.98-109.
Abstract: Social influence has a great impact on human behavior, which has been widely investigated in various research fields. Even so, it has rarely been investigated in the online health community. In this paper, we focus on the multichannel access in online health communities, defining social influence as the average degree of multichannel access to a physician's colleagues. Based on the multinomial logistic regression model, we examined the direct effects of social influence and patients' rating to multichannel access. In addition, we explored the moderating effect of social influence on the relationship between patients' rating and multichannel access in online health communities. The results of the experiment and robustness testing support the propositions that social influence and patients' rating significantly and positively affect multichannel access in an online health community. The moderating effect of social influence is negative and significantly influences the accessible channels provided by the focal physician. This research contributes to the literature concerning online health communities, social influence, and multichannel access; it also has practical implications.

2Chen, K.-n.: Dynamic subject numbers replace traditional classification numbers.
In: Knowledge organization. 40(2013) no.3, S.160-168.
Abstract: This article presents a new idea on shelving printed books and finding books in libraries. The author advocates that traditional book classification number (TBCN) systems should be replaced by a better indexing method for books in libraries. The author proposes a new way of seeking books for library users wishing to locate them called a 'dynamic book subject number' (DBSN) system. The new system combines new indexing rules and automated system technology to create settings in which a book's 'subject number' can change rather than having a particular permanent classification number assigned to it. The new way encourages library users to seek books through a user-friendly cataloging system by choosing subjects from the embedded database. The database contains thousands of subjects with their corresponding Arabic codes. For printed books, the DBSN ushers in a new era in the relationship between library users and the books.

3Chen, K.-n. ; Lin, P.-c.: Information literacy in university library user education.
In: Aslib proceedings. 63(2011) no.4, S.399-418.
Abstract: Purpose - The aim of this paper is to determine the essential features of information literacy; what role it should play in university library user education; and how programs can be best implemented. Design/methodology/approach - The researchers systemically surveyed and reviewed publications related to information literacy and library user education. Findings - It was found that a well-designed information literacy program benefits the library and its staff, faculty, and students; librarians should play a leading role in the design and operation of programs, but collaboration with faculty, IT professionals and students is essential; programs should be embedded in the curriculum, be largely cooperative, and be problem-based; evaluation and assessment are essential components; emphasis should be placed on first-year students; and, ideally, the librarians will turn into educators and the library will become a learning center combining learning, research and technology. Research limitations/implications - This paper reflects the opinions of the researchers and the authors of the reviewed literature who have insights into the issues related to information literacy and library user education. These opinions present useful guidelines for both librarian and teacher practitioners. Originality/value - This paper provides a point of view on the relationship between information literacy and library user education in the six themes described above.
4Chen, K.-H.: Evaluating Chinese text retrieval with multilingual queries.
In: Knowledge organization. 29(2002) nos.3/4, S.156-170.
Abstract: This paper reports the design of a Chinese test collection with multilingual queries and the application of this test collection to evaluate information retrieval Systems. The effective indexing units, IR models, translation techniques, and query expansion for Chinese text retrieval are identified. The collaboration of East Asian countries for construction of test collections for cross-language multilingual text retrieval is also discussed in this paper. As well, a tool is designed to help assessors judge relevante and gather the events of relevante judgment. The log file created by this tool will be used to analyze the behaviors of assessors in the future.
