美国高校图书馆实时参考服务试验项目研究

文章从人员配置、宣传推广、软件选择、咨询问题类型、服务评估等方面对8个美国高校图书馆的实时参考咨询试验项目进行了研究分析与经验总结。     

实时参考咨询的现状及发展问题探讨

实时参考咨询的过程模式体现了实时参考咨询实时交互的特点,而这一特点正是实时参考咨询备受图书馆和用户关注的原因。在实时参考咨询迅猛开展的同时,也存在着成本收益不平衡、时间配置不合理,人员态度、技术水平不完善等问题,导致了部分实时参考咨询服务项目无法开展。文章在分析问题的同时,为实时参考咨询未来发展提出建议,以推动实时参考咨询向合作化、复合化方向发展。     

Regulating research: The problem of theorizing community on LambdaMOO

This article considers ongoing attempts to regulate or even ban researchon LambdaMOO. Industry, private individuals, and research institutionshave supported MOOs, or multi-user object-oriented worlds. The earlyresearch on MOOs by Pavel Curtis, who was one of the key designers,suggests that these systems are part of a research project and have beenresearched since they were originally designed. However, a group ofMOOers have grown increasingly uncomfortable about the quotation ofcertain texts on web sites and academic journals and the potentiallypanoptic effect of research. Some of these practices have breachedcommunity conventions. Yet, such things as testing, invisibly watching,freely quoting characters, and ignoring certain rules have always beenaspects of the system. The dispute over research ethics and theparticipation of varied researchers within this setting indicate thatdiverse values are represented among MOOers and different expectationsexist about how the MOO might be a community. The term ``community' andthe presumption that online characters are people may have alsoincorrectly informed the research debate by making it seem that onlinesettings provide immediate access onto spaces, bodies, and individuals.Many MOOers may believe that research threatens individuals andcommunity. However, critical histories and analysis are needed in orderto explain the system to new users and encourage alternative forms ofdevelopment. Such work can only be produced if online systems are opento research and critique.

基于线上教学群聊文本的问句抽取模型

教学过程中产生的群聊文本往往包含着学生对于课程的思考。通过提取分析群聊文本中学生的提问,能够了解学生的学习情况,也能结合具体内容对学生进行指导。该研究旨在通过构建问句抽取模型,对群聊文本中与课程相关的提问进行提取。实验首先针对教学过程中产生的群聊文本进行收集,并结合课程相关教材进行数据清洗工作;然后针对类别分布不均匀问题,在Text-CNN模型的基础上提出了两种优化方式:引入注意力机制和使用平衡交叉熵损失函数。实验结果表明,优化后的模型能够达到91.95%的正确率,比原有模型增加了1.04%,而问句的F1-score表现为0.72,在原有模型的基础上提高了0.06。该模型能够运用到实际教学中,将群聊文本中与教学相关的学生提问抽取出来,再与线下教学相结合,提高教师的分析效率,进一步改善教学效果。     

网络时代大众对经典文学的多元性认知

文学与文学批评一直是文学发展史的双生子,长期以来,受限于传播媒介,民间受众的批评表现为自发性,在主流批评史上难以留下声音。新传媒出现以来,个体受众的批评声音得到广泛的呈现与传播。以对《红楼梦》的个体解读为个案研究,网络时代大众对经典文学在认知上存在考据式、带入式、反拨式等多元性的个体解读方式。新兴的个人批评话语臆舍当代文学批评标准的演变,对传统批评话语局面有所打破与拓展。     

Adding a Feature: Can a Pop-Up Chat Box Enhance Virtual Reference Services?

Online users seek help from virtual reference services via email, phone, texting, and live chat. Technologies have enabled new features in library websites to help make this service more accessible and effective. This article is an evaluation of an experimental pop-up live chat box on the website of a health sciences library to see whether the feature would enhance virtual reference services.

富裕家庭子女网络使用、成瘾倾向及相关因素分析

以452名富裕家庭子女为研究对象，运用《中学生网络使用问卷》和《中文版网络成瘾量表》进行调查。与以往研究相比，富裕家庭子女的网络使用基本情况出现了新的变化；高危人群学生表现出较为严重的网络成瘾倾向；对网络成瘾产生显著效应的因素是“网络在生活中的重要性”、“平均每次上网时间”、“性别”、“平均每月上网次数”、“上网的主要目的”。富裕家庭子女网络成瘾对正常的学习、生活、人际交往造成了严重的影响。
