在线健康社区老年用户健康信息需求实证研究 总被引:6,自引:3,他引:3
[目的/意义] 目前老年用户在使用健康信息的过程中得不到满足,且有关老年用户健康信息需求的研究尚有待加强。探索老年用户健康信息需求的内容和模型并寻求相关解决途径,可丰富老年用户健康信息需求的理论研究成果,并在实践中指导老龄化社会智慧养老以及在线医疗平台服务等议题。[方法/过程] 本研究依托在线健康社区,利用先定性后定量的混合型方法开展探索性研究,首先通过访谈老年用户获取了37个健康信息需求的自由节点,继而通过问卷调研并利用因子分析方法提取了使用操作、信息搜寻、隐私与安全、诊疗行为、交互与反馈、自我实现6大类健康信息需求的树节点并进一步归纳为物理、认知和情感3类主范畴。[结果/结论] 最终构建了老年用户健康信息需求模型,并结合马斯洛需求层次理论解释老年用户健康信息需求模型的内涵并提出相应的对策和建议。 相似文献

[目的/意义]从用户视角分析图书馆帮助民众有效消减信息搜寻焦虑的作用机理,自下而上地评估图书馆在信息社会化进程中为民众提供公共文化服务的实际成效。[方法/过程]通过对708位图书馆用户进行问卷调查,运用结构方程模型对个体特征、图书馆使用行为、图书馆使用体验和信息搜寻焦虑之间的相互作用机理进行实证检验。[结果/结论]个体的教育、经济差异通过中介变量对信息搜寻焦虑产生显著影响,表现为教育水平较低、经济收入较高的两组群体焦虑感更强;图书馆使用体验越好,越有助于消减用户日常信息搜寻活动中产生的焦虑感;图书馆使用行为对信息搜寻焦虑不存在显著影响,但对其子维度认知能力障碍与信息利用障碍存在间接的负向影响。 相似文献

Automatic word spacing in Korean remains a significant task in natural language processing owing to the extremely complex word spacing rules involved. Most previous models remove all spaces in input sentences and insert new spaces in the modified input sentences. If input sentences include only a small number of spacing errors, the previous models often return sentences with even more spacing errors than the input sentences because they remove the correct spaces that were typed intentionally by the users. To reduce this problem, we propose an automatic word spacing model based on a neural network that effectively uses word spacing information from input sentences. The proposed model comprises a space insertion layer and a spacing-error correction layer. Using an approach similar to previous models, the space insertion layer inserts word spaces into input sentences from which all spaces have been removed. The spacing error correction layer post-corrects the spacing errors of the space insertion model using word spacing typed by users. Because the two layers are tightly connected in the proposed model, the backpropagation flows are not blocked. As a result, the space insertion and error correction are performed simultaneously. In experiments, the proposed model outperformed all compared models on all measures on the same test data. In addition, it exhibited reliable performance (word-unit F1-measures of 94.17%~97.87%) regardless of how many word spacing errors were present in the input sentences. 相似文献

AbstractThere are a few studies in library literature that explore accessibility issues from the perspective of students who use assistive technologies for accessibility. As we shared in part one of this two-part series in our column, librarians have extensively explored through usability studies with WAVE and other audit tools how accessible library websites and databases are when using assistive technologies like JAWS. In this column, we asked our blind student worker to journal his experiences navigating our library’s databases. We found this student navigated the databases better than we anticipated. While his experiences regarding the accessibility of the libraries’ electronic services varied, common issues he experienced included navigational issues from menus with expanding capabilities, documents that were not scanned with OCR, and images without alternative text. 相似文献

ABSTRACTThe achievement of social justice, which implies the development of collections and the design of services for different user groups, is an objective present in the mission of public libraries. Since the 1950s, Croatian public libraries have been continuously developing collections and services for different user communities. However, one user community has remained largely unrecognized – LGBTIQ people. Therefore, the aim of the research presented in this paper is to examine the importance of the role of public libraries in the life of the LGBTIQ community in the Republic of Croatia. With a sample of 259 respondents, information behaviors, attitudes and experiences of LGBTIQ people in relation to public libraries have been examined via an online survey. In particular, this study explored the extent to which members of public libraries differ from non-members. The obtained results should contribute to a better understanding of the information needs and behavior of members of sexual minorities and help bring this group of users closer to (Croatian) public libraries by ensuring that libraries more adequately respond to their needs. 相似文献

[目的/意义]提出一种深入到文献内部、以文献中隐性专业知识本身作为计量对象的科学计量方法,为在大数据等新环境下开展面向专业实践应用的科学计量研究提供新思路。[方法/过程]在对知识元研究进行系统梳理基础上,结合案例提出一种具有计量属性、表征科学内涵的专业知识元定义,并以地震预警领域为例对基于知识元科学计量方法的可行性和实用性进行检验。[结果/结论]基于知识元的科学计量方法,能够实现科学计量与内容分析的有机结合,以专业用户的关注点作为切入方向,通过对文献中专业知识元的抽取分析,为用户提供解决实际问题的知识产品,满足专业用户的情报需求。 相似文献

[目的/意义] 通过分析科研人员对电子资源的需求状况,以期从用户视角为研究型图书馆制定合理的电子资源发展策略提供数据支持和参考依据。[方法/过程] 运用问卷调查方法分析电子环境下科研人员对电子资源的使用现状、使用偏好及影响因素、发展预期与建议等内容。[结果/结论] 调查结果表明:当前科研人员对电子资源的依赖程度很高,且使用呈现出新特点,如符合"二八"定律、使用渠道多元化、依赖商业搜索引擎、关注开放获取资源和资源共享服务等;科研人员对电子资源的使用偏好受科研人员类型、资源类型以及电子资源本身优劣势的影响而存在差异;科研人员对"纯电子时代的到来"呈谨慎乐观态度,但普遍认为电子资源建设会对图书馆行业产生颠覆性变革与影响。调查所选取的样本数据质量较高、调查过程控制严格,数据处理和分析科学严谨、调查结果真实可信。 相似文献

This paper reports findings from a study of LookJed, the oldest and largest on-line forum for Computer Mediated Discussion
among individuals interested in Jewish education. The study adopted a “cyber-ethnographic” approach, with postings to the
forum seen as “acts of communication” that reveal what is important to their authors. An interest in exploring similarities
between forum conversations and those in teachers’ lounges led to an investigation of Herring’s claim that most listservs
do not include discussion at all, only the trading of information. This investigation found that active forum participants
generally use the forum for discrete purposes, most commonly to exchange information about “subject matter” or “teaching material”,
less commonly to exchange opinions and ideas, and rarely to do both. Integrating an analysis of patterns of contribution with
an examination of their discursive content reveals six preeminent “types” among the population of contributors, each of whom
participates in the forum in different ways and acts with different purposes. Although this typology is at best suggestive
and needs to be tested against other listserv cases, its easy identification suggests that in order to better understand the
cultures of virtual forums, it is important to pursue a more variegated characterization of listserv participants and their
motivations than has typically been the case in CMD research where users are most frequently identified as either lurkers
or fanatics, or as active or passive participants. 相似文献

数字图书馆像其他新技术一样,其能否有效使用依托于用户对它的接受度,同时这种接受度又会受到用户对系统易用性认识的影响。新技术的引进应用往往包含某种针对用户的变化,而最近针对阻碍个性变革的现象的发现,以及对其一系列的测评方法的产生,为客观评定阻碍数字图书馆系统变革和对新用户的影响,提供了一个很好的分析平台。以往有研究将个性差异与系统特性作为影响认知易用性的因素,根据这类研究,他们发现阻碍变革不仅是决定认知易用性的一个非常重要的因素,而且会提高对过去技术接受模式的阐释力。 相似文献
