基于词向量扩展的学术资源语义检索技术 总被引:1,自引:0,他引:1
[目的/意义] 尝试以统计的方法为指导思想,探究基于词向量扩展的语义检索技术来提升学术资源的语义检索能力。[方法/过程] 利用自然语言处理、文本挖掘技术,对采集来的学术资源(主要是学术论文)元数据进行预处理,结合word2vec词向量生成工具和elasticsearch全文检索引擎搭建语义检索系统,对学术资源进行语义检索的探索研究。[结果/结论] 本文提出的方法能够有效提升学术信息的检索效果,一定程度上实现学术资源的语义检索,并为后续语义检索的进一步研究提供借鉴。 相似文献

ABSTRACTGlocalization describes the adaptation of international products around the particularities of a local culture, and extends to areas beyond political campaigns and cultural communication. Chinese continuing resources are effectively influenced by glocalization, which reflects the changing society in China and Chinese overseas communities, as well as the changing practice in Chinese studies all over the world. Glocalization brings unexpected challenges to a library's cataloging service, and a number of issues need to reach our awareness and be solved. We have to face squarely its influence, and look for an appropriate solution in handling Chinese continuing resources under glocalization. 相似文献

ABSTRACTThe career path and significant professional accomplishments of librarian Valerie Bross (1954–2016) are described in this article. The awards and recognition she received are recounted and the influence of outside activities on her career is assessed. An attempt is made to capture what she was like as a professional, as well as what her unique characteristics were. A bibliography of her writings and a photograph are included. 相似文献

Our library has previously investigated the potential impact the addition of contents notes on circulation. In a subsequent study, we found contents notes were the second metadata element most heavily linked to circulation (title was first). Since there has been a marked decline in the use of print resources at our library and a corresponding increase in digital resources, we wanted to know if the addition of contents notes to records for online streaming audio files would result in a similar increase in usage. After enhancing the records, we tracked usage for a period of three months. 相似文献

The information-seeking behavior of social science graduate students has been the subject of many studies, but none have concentrated only on the economics graduate student population and their unique needs. The purpose of this focus group study was to use group discussions to understand the actual online behavior of graduate economics students when conducting research. The results provide insight and information about the skills and characteristics of economics graduate students, their first steps in conducting research online, their use of publicly available and library resources, challenges to finding information, and resources used to overcome these challenges. 相似文献

This column describes the development and implementation of a responsive library course designed to train third-year medical students as they begin their clerkships. The course design consisted of a brief face-to-face introduction during third-year orientation and an online course developed in Canvas, an online learning management system. The objective of the course was to not only introduce students to the resources but also to teach them how to effectively use those resources at the point-of-care. Students evaluated the course to assess the overall effectiveness of the instruction. Course development and content, feedback provided by students, as well as suggestions for improvement are discussed. 相似文献

ABSTRACTOpen education resources represent a great opportunity to reduce textbook costs, but many of them have not been evaluated for quality. Librarians and former students in an introduction to engineering course collected and evaluated open education resources to supplement the course textbook in future semesters. Both searching for and evaluating these resources created opportunities for the librarians to evaluate information literacy skills of these students and to provide instruction to improve these skills. 相似文献

摘要:我国高等体育教育资源优化配置研究引入社会学视角理论与方法,理论与实践均取得专家的认同。运用文献资料法、专家访谈法和实地考察法等方法发现,在计划经济体制下我国高等体育教育资源配置主体单一性、手段行政化和政治倾向性强,凸显出高等体育教育资源配置缺乏激励机制和市场竞争机制的问题,造成高等体育教育资源配置成本最大化和社会效应的最小化问题较多。自改革开放以来,随着我国市场经济体制的建立为高等体育教育资源优化配置提供了难得的发展机遇,我国高等体育教育资源配置取得了明显成效,但仍然存在高等体育教育资源配置机制滞后、体制机制改革创新步伐缓慢、高等体育教育资源配置不合理以及民办普通高校体育教育资源配置严重不足等问题。据此,从社会学研究的视角,提出了构建多主体推动高等体育教育资源优化配置创新的发展模式、多元化高等体育教育资源优化配置资金投入的保障体系、高等体育教育资源优化配置均衡发展的运行机制和大学城体育教育资源“共建共享”的创新发展模式的新时代我国高等体育教育资源优化配置的发展策略,旨在服务新时代全民健身与全民健康深度融合发展,“推动构建人类命运共同体”发展目标的实现。 相似文献

大学与中小学(U-S)合作是当前教师教育的一条有效出路。但目前我国教师教育U-S合作过程存在严重的结构性障碍,主要表现为合作中的异质性资源依赖感不强,合作主体的合法性认同严重不足,合作协调机制缺位。因此,我们需要充分挖掘U-S合作中的异质性资源,增强双方异质性资源依赖程度;赋予中小学教师教育义务并提升合作双方的利益共识,增强合作主体的合法性认同;构建政府统筹的U-S合作管理体制,规范合作行为。 相似文献

This paper explores the impact of acculturation conditions, orientations and outcomes on international students in Australia’s tertiary education sector. Specifically, we investigate the factors that facilitate or hinder acculturation of international students within a multidimensional acculturation context (Arends-Tóth & van de Vijver, 2006). We used a sequential exploratory mixed-methods design in two studies to investigate acculturation of international students at an Australian university and test how these factors are related to psychological and sociocultural outcomes. In Study 1, we conducted a generic qualitative study using semi-structured interviews with a conventional content analyses approach,which compared the experiences of international students who on average had high numbers of positive experiences versus those who had high numbers of negative experiences. We found that a support network of mixed-nationals, and especially host locals, facilitates positive psychological and sociocultural adjustment, and buffers acculturative stress. Study 2 quantitatively tested the association of factors found in Study 1 (perceived stereotypes, intercultural and ethnic network/resources) with psychological and sociocultural acculturation outcomes. Study 2, shows that perceived negative stereotypes loosen ties with the dominant (host) culture and reinforces ties with the ethnic (non-host) culture. The social resources associated with either culture was found to be useful for acculturation, with both independently contributing to participant well-being. Contact with host locals played a particularly crucial role in developing these resources. Our findings provide foundations for pragmatic policy implications, suggesting value in the development of formally organized contact programs in the early sojourn experience of international students. 相似文献
