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。     

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.

Virtual Reference Services

Abstract

Researchers performed a cost and benefit analysis of the University of South Florida's locally controlled chat service and compared the results to the advantages and expenses associated with a chat consortium. An evaluation of chat sessions revealed that a substantial portion of the inquiries received relate to university-specific interests. In addition to the local nature of chat questions, library staff used USF statistics to estimate the staffing, software, and training costs of the current chat reference service. The collaborative service under consideration involves both additional costs and benefits. A final decision, however, requires an in-depth assessment of several factors. Supplementary factors in this examination include a brief history of USF virtual reference service and the current trends in instant messaging that support the continuance of chat reference.     

Chat Reference at Carnegie Mellon University

Abstract

Carnegie Mellon University Libraries began its chat reference service in October of 2000. The article explains why library administrators decided to institute chat reference and the steps taken to implement this decision. The Libraries utilize commercial off-the-shelf software called LivePerson. Service evaluation features of LivePerson provide interesting data for analysis. Summary statistics of the service and the cumulative results of post chat surveys (filled out by chat patrons on a voluntary basis) are presented. Plans for future enhancements of the chat reference service are discussed.
