Consortial Ebook Archiving Environmental Scan

Academic libraries and consortia are spending the vast majority of their material budgets on digital content, including ebooks. A review of ebook preservation activities for the North American library consortia is provided along with a look at the major preservation services such as Portico, CLOCKSS and HathiTrust. Publishers and ebook aggregators are also examined to provide a broad environmental scan of the current ebook preservation activities and risks.     

Assessing the Benefits of Content Notes Enhancements for Digital Audio Resources

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.     

电子健康网站用户信息披露行为影响因素研究

[目的/意义]旨在确定信息披露行为影响因素,优化电子健康网站生态环境,间接助力"健康中国2030"战略目标的实现。[方法/过程]采用质性研究方法,对访谈资料进行三级编码,抽取影响电子健康网站用户信息披露的17个主范畴及5个核心范畴,并构建电子健康网站用户信息披露行为影响因素模型。[结果/结论]电子健康网站用户信息披露行为主要受到用户感知效用、感知风险、主观规范、服务质量和病情特征影响。其中,感知效用是最重要影响因素,感知风险是次重要影响因素,主观规范是较重要影响因素,服务质量和病情特征是相对不重要影响因素。据此,从政府部门、电子健康网站和用户3个维度,总结相关启示。

Diverse socio-technical aspects of a digital archive of Aboriginal languages

ABSTRACT

A socio-technical approach is taken to explore a digital archive of Australian Indigenous cultural heritage. The Living Archive of Aboriginal Languages is considered in terms of what it is currently doing and what it was intended to do. Two ethnographic stories focusing on user interactions and the outcomes of an online survey serve to evaluate the effectiveness of the Archive from the perspective of different users. This is then juxtaposed with a consideration of the original grant application, outlining what was envisaged for the project. This analysis serves to highlight some of the contingent relations and diverse socio-technical aspects of a specific knowledge infrastructure, as it allows multiple forms of interaction, new connections and generative activities as people discover, access and interact with the content now and into the future.     

中文电子病历的分词及实体识别研究

[目的/意义]健康医疗大数据是我国重要的基础性战略资源，本研究对中文电子病历分词与实体识别的探讨与实证较好地完成了医疗数据的信息抽取任务，对今后医疗大数据在语义层面的应用发展具有重要意义。[方法/过程]本研究首先融合权威词表、官方标准、健康网站数据及其他医学补充词库构建了词语数量级达到10万的医学词表；然后对电子病历的字段进行分词，对比了jieba工具、导入词典后的jieba、无监督学习及AC自动机4种模型的分词效果；最后，以自动分词和人工标注结果为语料，实现基于条件随机场的电子病历实体识别研究，并比较不同实体类别以及不同文本特征下的实体识别效果，选出最优模板。[结果/结论]分词结果显示，AC自动机的效果最好，F值可达82%；实体识别结果表明，"检查"和"疾病"实体的识别效果最好，而"症状"的识别效果不太理想。
