Analysis of Academic Libraries' Facebook Posts: Text and Data Analytics     

Sultan M. Al-Daihani  Alan Abrahams 《The Journal of Academic Librarianship》2018,44(2):216-225

This research analyzed a dataset of academic libraries' posts on Facebook. It applied a text and data analytics approach to a dataset collected from the Facebook posts of academic libraries at the top 100 English-speaking universities, as listed by the 2014 Shanghai World University Rankings. The dataset is from a two-year posting history of 18,333 unique posts, 113,621 likes, and 3401 comments. Less than a quarter of the libraries had more than 2000 post-related likes, and only seven received more than 100 comments on their postings. Content analysis identified the most prevalent single word (unigrams), bigrams (two-word sequences), and trigrams (three-word sequences) in high and low engagement content. Semantic analysis identified the semantic categories for posts with high and low engagement. The findings can assist academic libraries in their social media strategies for engagement, marketing, and visibility.  相似文献   

Trends of infodemiology studies: a scoping review          下载免费PDF全文

Kimia Zeraatkar  Maryam Ahmadi 《Health information and libraries journal》2018,35(2):91-120

Introduction

The health care industry is rich in data and information. Web technologies, such as search engines and social media, have provided an opportunity for the management of user generated data in real time in the form of infodemiology studies. The aim of this study was to investigate infodemiology studies conducted during 2002–2016, and compare them based on developed, developing and in transition countries.

Methods

This scoping review was conducted in 2017 with the help of the PRISMA guidelines. PubMed, Scopus, Science Direct, Web of Knowledge, Google Scholar, Wiley and Springer databases were searched between the years 2002 and 2016. Finally, 56 articles were included in the review and analysed.

Results

The initial infodemiology studies pertain to the quality assessment of the hospital's websites. Most of the studies were on developed countries, based on flu, and published in the Journal of Medical Internet Research.

Conclusion

The infodemiology approach provides unmatched opportunities for the management of health data and information generated by the users. Using this potential will provide unique opportunities for the health information need assessment in real time by health librarians and thereby provide evidence based health information to the people.

The more multidisciplinary the better? – The prevalence and interdisciplinarity of research collaborations in multidisciplinary institutions     

Zhiya Zuo  Kang Zhao 《Journal of Informetrics》2018,12(3):736-756

Scientific research is increasingly relying on collaborations to address complex real-world problems. Many researchers, policymakers, and administrators consider a multidisciplinary environment an important factor for fostering research collaborations, especially interdisciplinary ones that involve researchers from different disciplines. However, it remains unknown whether a higher level of multidisciplinarity within an academic institution is associated with internal collaborations that are more prevalent and more interdisciplinary. Analyzing 90,000 publications by 2500 faculty members in over 100 academic institutions from three multidisciplinary areas, information, public policy, and neuroscience, we investigated the connection between multidisciplinarity and research collaborations. Based on social network analysis and text mining, our analysis suggests that more multidisciplinary institutions are not necessarily more collaborative, although they do feature collaborations that are more interdisciplinary. Our findings provide implications for academic administrators and policymakers to promote research collaborations and interdisciplinarity in academic institutions.  相似文献   

1950年代计划经济体制中国化的基本经验     

胡安全 《安徽师范大学学报(人文社会科学版)》2011,39(4):379-385

改革开放历史起源之一是对计划经济体制在中国最初实践经验的思考和结合中国实际进行改革的初步尝试。1950年代,中国共产党人在推进社会主义改造和建立社会主义制度的同时,就提出、探讨了将苏联计划经济同中国具体实际相结合、建立中国式的社会主义经济体制这样一个历史课题。在实践中,中共提出了发挥中央和地方两个积极性、社会主义经济是计划性与多样性和灵活性的统一、三个主体与三个补充相结合等一系列思想,取得了丰富的经验。这些思想和经验成为中国特色社会主义兴起的重要基础。  相似文献   

中文电子病历的分词及实体识别研究   总被引：1，自引：0，他引：1  

王若佳  赵常煜  王继民 《图书情报工作》2019,63(2):34-42

[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。  相似文献   

皖南二县五村农民收入与土地关系调查     

唐京力 《安徽师范大学学报(人文社会科学版)》2011,39(4):464-471

利用皖南两县五村社会调查资料,分析各类农民家庭的经济状况及其在收入和生活水准上的差别;考察农民对土地承包权的态度及其影响因素。结果表明,官方有关农民收入的数据,存在着低估的可能;农户不愿意放弃土地承包权的占大多数,但是如果国家征收土地时满足农民的一定要求,他们仍愿意放弃或出让。  相似文献   

Impacts of social economic status on higher education opportunity and graduate employment in China     

Dong-mao Wen 《Frontiers of Education in China》2006,1(3):426-438

Based on a nation-wide survey of higher education graduates, this paper analyzes the impact of family background, using paternal occupation and education as indicators, on their scores in the National College Entrance Examination, the level and type of higher education institutions they attend, their employment after graduation, and the income they receive from their first job. It has been found that there are wide disparities among students with different family backgrounds in both access to higher education and their potential employment in China nowadays. This paper also studies how those influences happen. __________ Translated from Peking University Education Review, 2005 July (3)  相似文献   

关于深化国有资源有偿使用制度改革的理论初探     

武心英 《连云港职业技术学院学报》2007,20(2):43-45

在粗放型的经济增长方式下，由于我们过多地运用了行政手段来管理经济，管理国有自然资源，导致国有自然资源一直是无偿或低廉使用的。随着我国经济增长方式的根本性转变，国有资产无偿使用制度的弊端已显现，一是导致国有自然资源的收益大量流失；二是导致国有资源配置无序和扭曲。因此，深化国有资源的有偿使用制度改革，对于维护国有资源的权益，加强资源开发者的经济责任，实现资源的最优配置，加速与国际通行做法的并轨，具有极为重要的现实意义，有广为实行之必要。  相似文献

"文革"时期经济体制变动的逻辑嬗变     

朱耀斌 《黄冈师范学院学报》2004,24(1):12-15

“革”时期经济体制的变动保持了放权改革的一般逻辑，但创设战备型的体制模型强化了计划的控制，限制了改革的进一步深入。“抓革命，促生产”的制度逻辑安排限定了体制变动的方式，歪曲了体制化观念，对中国的经济体制变动产生了消极的影响。解放体制观念，培育新的制度化，应是当务之急。  相似文献
