This article investigates the characteristics of KORMARC (Korean Machine Readable MARC) format and the role and influence of KORMARC on the development of library automation in Korea, as an example of library automation in the developing countries. The first section is a general overview of the development of KORMARC. In the second section, the characteristics of the KORMARC format for monographs are investigated, mainly based on the bibliographic characteristics in the East-Asian countries. In the third section, the influence of KORMARC on library automation in Korea is reviewed along with the prospects for the future. 相似文献

The Influence of James C. McCroskey’s Research in South Korea 总被引：1，自引：1，他引：0
In honor and remembrance of Dr. James C. McCroskey, this article looks at McCroskey’s influence in Korean academic fields. We find that McCroskey’s scholarly articles and books were increasingly cited from 2001 to 2016 and that his work has been cited in Korean journals across diverse fields. In addition to the communication and education fields, McCroskey was cited also in the fields of science and medicine in South Korea. The findings document the international and interdisciplinary impact of McCroskey’s scholarship. 相似文献

This case study reports on the implementation of student-generated questioning using a customized personal response system (PRS) by two groups of students in second language (L2) courses at a university in the United States. This study aimed to understand more about instructor and student experience with student-generated questioning for promoting student interaction in the L2 classroom, and sources for investigation included class observation, instructor interview, student survey, and pre/post-test. The results of this study indicated that the classroom interaction could be fostered through student-generated questioning with the support of PRS in L2 courses. In addition, there was a significant difference in students’ achievement between the pre- and post-test. The results are consistent with the findings of previous studies that student-generated questioning fosters collaborative interactions and increases frequency of student engagement. The results also suggest that the adoption of student-generate questioning with a technology support may result in promoting classroom interactions where the students are able to practice the target language through conversation with an instructor and peers. 相似文献

Using the analytical tools of broadening, burrowing and storying and restorying, this narrative inquiry examines a middle school teachers’ knowledge of her pedagogical practices through the strand of pearls’ metaphor that she employs to explain her teaching to herself, a beginning teacher whom she mentors and ourselves as researchers. Throughout the discussion, careful attention is paid to the pearl metaphor’s emergent, novel qualities and how the metaphor is held and expressed in the teacher’s unfurling practice. In the final analysis, four significant themes are unpacked: (1) the image of teacher as curriculum maker; (2) the idea of pearls, non-pearls and yellowed pearls; and (3) the concept of metaphors and the nature of metaphorical truth. Finally, a discussion of the veracity of the strand of pearls as way to understand teaching practice concludes the article. 相似文献

With the advances in natural language processing (NLP) techniques and the need to deliver more fine-grained information or answers than a set of documents, various QA techniques have been developed corresponding to different question and answer types. A comprehensive QA system must be able to incorporate individual QA techniques as they are developed and integrate their functionality to maximize the system’s overall capability in handling increasingly diverse types of questions. To this end, a new QA method was developed to learn strategies for determining module invocation sequences and boosting answer weights for different types of questions. In this article, we examine the roles and effects of the answer verification and weight boosting method, which is the main core of the automatically generated strategy-driven QA framework, in comparison with a strategy-less, straightforward answer-merging approach and a strategy-driven but with manually constructed strategies. 相似文献

A group recommendation system for online communities 总被引：1，自引：0，他引：1

Online communities are virtual spaces over the Internet in which a group of people with similar interests or purposes interact with others and share information. To support group activities in online communities, a group recommendation procedure is needed. Though there have been attempts to establish group recommendation, they focus on off-line environments. Further, aggregating individuals’ preferences into a group preference or merging individual recommendations into group recommendations—an essential component of group recommendation—often results in dissatisfaction of a small number of group members while satisfying the majority. To support group activities in online communities, this paper proposes an improved group recommendation procedure that improves not only the group recommendation effectiveness but also the satisfaction of individual group members. It consists of two phases. The first phase was to generate a recommendation set for a group using the typical collaborative filtering method that most existing group recommendation systems utilize. The second phase was to remove irrelevant items from the recommendation set in order to improve satisfaction of individual members’ preferences. We built a prototype system and performed experiments. Our experiment results showed that the proposed system has consistently higher precision and individual members are more satisfied. 相似文献
