Abstract

The Mystery Room is an educational escape room based on information literacy and applied to multiple audiences, including first-year students and library student employees. In this article, we explain how we developed the game, its theoretical underpinnings, and why it’s a flexible workshop for a variety of audiences.  相似文献   

Quality flaw prediction in Spanish Wikipedia: A case of study with verifiability flaws

In this work, we present the first quality flaw prediction study for articles containing the two most frequent verifiability flaws in Spanish Wikipedia: articles which do not cite any references or sources at all (denominated Unreferenced) and articles that need additional citations for verification (so-called Refimprove). Based on the underlying characteristics of each flaw, different state-of-the-art approaches were evaluated. For articles not citing any references, a well-established rule-based approach was evaluated and interesting findings show that some of them suffer from Refimprove flaw instead. Likewise, for articles that need additional citations for verification, the well-known PU learning and one-class classification approaches were evaluated. Besides, new methods were compared and a new feature was also proposed to model this latter flaw. The results showed that new methods such as under-bagged decision trees with sum or majority voting rules, biased-SVM, and centroid-based balanced SVM, perform best in comparison with the ones previously published.  相似文献

郝纲 《当代体育科技》2020,(11):179-179,181

作为一项历史悠久的运动,足球运动深受全民喜爱,有着广泛的扩展范围和巨大的影响力。近些年来,高职院校的足球教学取得一定的进步和发展,对于学生身体素质的锻炼起到积极的促进作用。然而,进步并不等同于完美,高职院校的足球教学仍然存在诸多问题,要想提升足球训练水平,必须要解决这些问题,创新教学思想,改善训练方式,保证足球教学的规范性、科学性、系统性,使足球训练具备的提升学生身体协调性的作用充分发挥出来。基于此,本文就如何提升高职足球教学训练水平进行论述。  相似文献   

协同搜索过程中用户交流内容与模式研究     

张璐  张鹏翼  刘畅 《图书情报知识》2020,(3):51-62

[目的/意义]旨在分析协同搜索用户在信息搜索任务过程中的交流内容与模式,从而理解协同搜索用户的关注重点与搜索过程。[研究设计/方法]基于书籍交互检索平台(CLEF-Social Book Search)设计实验,共招募18名被试完成两种搜索任务,通过录音记录对话并对其进行编码和分析,总结交流内容特征和模式。结合任务类型、认知类型组合、服务器记录的搜索交互行为日志以及问卷收集的搜索体验进行了探索分析。[结论/发现]从交流内容上看,协同搜索用户主要理解与评判书目信息、商讨搜索任务计划;比起认知类型不同的用户,相同认知类型的用户在操作交互方面交流更多,在评判决策方面交流较少。交流模式依据讨论内容比重可分为理解评判型、评判主导型、均衡交流型三种,评判主导型用户的任务完成满意度最高。[创新/价值]协同搜索用户的交流反映出搜索过程中需要与同伴商讨协同的焦点,也是需要系统提供协助的重点,给协同搜索系统设计提供一定参考。本研究针对协同搜索的交流内容设计的编码系统对相关的协同交流研究也有借鉴意义。  相似文献   

Beyond traditional collaborative search: Understanding the effect of awareness on multi-level collaborative information retrieval     

Nyi Nyi Htun  Martin Halvey  Lynne Baillie 《Information processing & management》2018,54(1):60-87

Although there has been a great deal of research into Collaborative Information Retrieval (CIR) and Collaborative Information Seeking (CIS), the majority has assumed that team members have the same level of unrestricted access to underlying information. However, observations from different domains (e.g. healthcare, business, etc.) have suggested that collaboration sometimes involves people with differing levels of access to underlying information. This type of scenario has been referred to as Multi-Level Collaborative Information Retrieval (MLCIR). To the best of our knowledge, no studies have been conducted to investigate the effect of awareness, an existing CIR/CIS concept, on MLCIR. To address this gap in current knowledge, we conducted two separate user studies using a total of 5 different collaborative search interfaces and 3 information access scenarios. A number of Information Retrieval (IR), CIS and CIR evaluation metrics, as well as questionnaires were used to compare the interfaces. Design interviews were also conducted after evaluations to obtain qualitative feedback from participants. Results suggested that query properties such as time spent on query, query popularity and query effectiveness could allow users to obtain information about team's search performance and implicitly suggest better queries without disclosing sensitive data. Besides, having access to a history of intersecting viewed, relevant and bookmarked documents could provide similar positive effect as query properties. Also, it was found that being able to easily identify different team members and their actions is important for users in MLCIR. Based on our findings, we provide important design recommendations to help develop new CIR and MLCIR interfaces.  相似文献   

Using the Information Structure Model to Compare Profile-Based Information Filtering Systems     

Yuval Elovici  Bracha Shapira  Paul B. Kantor 《Information Retrieval》2003,6(1):75-97

In the IR field it is clear that the value of a system depends on the cost and benefit profiles of its users. It would seem obvious that different users would prefer different systems. In the TREC-9 filtering track, systems are evaluated by a utility measure specifying a given cost and benefit. However, in the study of decision systems it is known that, in some cases, one system may be unconditionally better than another. In this paper we employ a decision theoretic approach to find conditions under which an Information Filtering (IF) system is unconditionally superior to another for all users regardless of their cost and benefit profiles.It is well known that if two IF systems have equal precision the system with better recall will be preferred by all users. Similarly, with equal recall, better precision is universally preferred. We confirm these known results and discover an unexpected dominance relation in which a system with lower recall will be universally preferred provided its precision is sufficiently higher.  相似文献

对我国体育竞赛市场运作环境的分析   总被引：7，自引：1，他引：6  

陈锡尧  庞徐薇 《体育科研》2001,22(2):15-15,17

随着我国经济体制改革的不断深化和体育产业化的不断扩大,我国的体育竞赛活动由原来的行政指令性计划举办正在向市场运作的方向转换.因此,体育竞赛若要步入市场,就必须研究市场环境,而微观环境则是体育竞赛活动进行市场运作能否成功的关键因素.通过对我国体育竞赛活动的微观环境的构成进行分析,有利于我们对体育竞赛市场化运作的充分认识,从而能够准确把握我国体育竞赛市场运作的一般规律.  相似文献
