In the last two decades, the concept of student-centered learning and problem-based learning (PBL) have swept through the educational community in most of the advanced countries. In medical PBL education, traditionally in order to train the students to be able to diagnose a patient with certain symptoms, the training procedure is always very time-consuming and labor-intensive. In particular there are usually only very limited number of specialists in practice. In order to solve this problem, we have developed a web-based PBL training system for medical education. The system can emulate a real clinical case that enables students to go through each step of a diagnosis procedure in an attempt to diagnose and cure a patient's disease. We believe that the system can significantly improve the learning efficiency and effectiveness for medical education.
在过去的二十年里,以学生为中心的学习和基于问题的学习(PBL)的概念席卷了大多数发达国家的教育界。在医学PBL教育中,传统上为了训练学生能够诊断具有某些症状的病人,训练过程总是非常耗时和费力的。特别是在实践中,通常只有非常有限的专家。为了解决这一问题,我们开发了基于网络的PBL医学教育培训系统。该系统可以模拟真实的临床病例,使学生能够经历诊断过程的每一步,以尝试诊断和治疗患者的疾病。我们相信该系统可以显著提高医学教育的学习效率和效果。

Pushing the Digital Notice Board toward Ubiquitous Based on the Concept of the Internet of Everything 基于万物互联理念推动数字公告牌走向无处不在

Recently, digital notice boards have demonstrated their Internet of Things (IoT)-ready advantage and competitiveness in message publishing environments (e.g., smart campus environments or bus stations). However, current digital notice applications do not capture the context of daily life usage behavior and scenarios, and input devices, boards, notices, and the experience of human beings are all separate. This paper proposes an interactive message exchange architecture based on the Message Queuing Telemetry Transport (MQTT) protocol that deeply involves users in the IoT process. In this design, users can post notices from handheld devices to any supported display device or social media through a topic naming mechanism based on a subscribe/publish (sub/pub) model. Users can decide which notice to address. Messages of interest to the user will be integrated into a personal knowledge base. This paper also provides a demonstration of an integrated system for a smart campus.
最近,数字公告板在信息发布环境(例如智能校园环境或公交车站)中展示了其物联网(IoT)就绪的优势和竞争力。然而,目前的数字通知应用并没有捕捉到日常生活使用行为和场景的背景,输入设备、公告板、通知和人类的经验都是分开的。本文提出了一种基于消息队列遥测传输(MQTT)协议的交互式消息交换架构,使用户深度参与到物联网过程中。在这种设计中,用户可以通过基于订阅/发布(sub/pub)模型的主题命名机制,从手持设备向任何受支持的显示设备或社交媒体发布通知。用户可以决定处理哪个通知。用户感兴趣的信息将被集成到个人知识库中。本文还提供了一个智能校园集成系统的演示。

ICT leadership of the school administrators is an important factor which would affect the school ICT development. However, theoretical research on ICT leadership training has been not common. Based on MOOC platform, this paper designed an ICT leadership online course, and discussed the learning behavior patterns of administrators in the course of learning the course. Besides, the learning behavior data generated in the MOOC platform was analyzed by content analysis and lag sequence analysis. This study found that the behavior of learning course content was the main learning behavior of learners, but this behavior had no significant relationship with other behaviors. Learners could actively participate in discussion in the forum, but the interaction was largely for the purpose of getting good grades. Active learners were always able to participate in unit tests repeatedly, submitted homework on time and carried out peer reviews, so as to obtain the certificate.
学校管理者的ICT领导力是影响学校ICT发展的重要因素。然而,关于ICT领导力培训的理论研究并不多见。本文基于MOOC平台,设计了一门ICT领导力在线课程,并探讨了管理员在学习课程过程中的学习行为模式。此外,对MOOC平台生成的学习行为数据进行了内容分析和滞后序列分析。本研究发现,学习课程内容的行为是学习者的主要学习行为,但该行为与其他行为的关系不显著。学习者可以积极参与论坛的讨论,但这种互动主要是为了取得好成绩。主动学习者总是能够多次参加单元测试,按时提交作业并进行同行评审,从而获得证书。

Forming the Best Team for a Composite Competition 为一项综合竞赛组建最佳团队
Pub Date : 2019-08-01 DOI: 10.1109/Ubi-Media.2019.00059

In a large database, the top-k query is an important mechanism to retrieve the most valuable information for the users, which ranks data objects with a ranking function and reports the k objects with the highest scores. However, as an object usually has various scores in the real world, ranking objects without information loss becomes challenging. In this paper, we model the object with multiple scores as an uncertain data object, where the uncertainty of the object is captured by a distribution of the scores, and address a novel problem named Best-kTEAM query, which discovers the best team with k players for a composite competition consisting of several games each of which requires a distinct number of players. To tackle the problem, we develop a dynamic programming based approach TeamGen to generate all possible solutions. Then, we introduce the notion of skyline teams with the property that none of them has a higher aggregated probability to be the top one for all games against the others and propose a filtering approach SubsetFilter to fast retrieve candidate solutions. Furthermore, instead of TeamGen, two heuristic approaches IgnoreTeamGen and LimitTeamGen are proposed to attempt to obtain possible solutions with better efficiency. The simulation shows the superiority of Best-kTEAM query in a composite competition and the proposed algorithms outperform the baseline approaches.
在大型数据库中,top-k查询是为用户检索最有价值信息的重要机制,它使用排序函数对数据对象进行排序,并报告得分最高的k个对象。然而,由于一个对象在现实世界中通常有不同的分数,因此在不丢失信息的情况下对对象进行排名变得具有挑战性。在本文中,我们将具有多个分数的对象建模为不确定数据对象,其中对象的不确定性通过分数的分布来捕获,并解决了一个名为best - kteam查询的新问题,该问题用于在由多个游戏组成的复合比赛中发现具有k名球员的最佳团队,每个游戏都需要不同数量的球员。为了解决这个问题,我们开发了一种基于动态规划的方法TeamGen来生成所有可能的解决方案。然后,我们引入了天际线团队的概念,其属性是它们中没有一个具有更高的聚合概率成为所有比赛的第一名,并提出了一种过滤方法SubsetFilter来快速检索候选解决方案。此外,本文提出了两种启发式方法IgnoreTeamGen和LimitTeamGen来代替TeamGen,试图以更高的效率获得可能的解决方案。仿真结果表明了Best-kTEAM查询在复合竞争中的优越性,所提算法优于基线方法。

To improve the vocabulary ability is very important in language learning. Thus, if we can learn and remember a word very effectively, then we will be able to master a language more quickly. Therefore, many scholars began to propose related research. Due to the learning mechanism of human brain, sometimes when people learn a new knowledge they may forgot at a short time. In order to make the consideration more complete, after analyzing Hermann Ebbinghaus's forgetting curve experiment, we added two variables, one is the acceptance of each word by the same person, and the other is the ability of different people to remember vocabulary. With the above two parameters, we want to design a system to help user to review the vocabulary which may be forgetting before. The forgetting curve can be personalized, and it is more accurate to calculate the best time for each user to review the vocabulary.
提高词汇能力在语言学习中是非常重要的。因此,如果我们能非常有效地学习和记忆一个单词,那么我们就能更快地掌握一门语言。因此,许多学者开始提出相关的研究。由于人类大脑的学习机制,有时人们在学习新知识时可能会在短时间内忘记。为了使考虑更加完整,在分析了Hermann Ebbinghaus的遗忘曲线实验后,我们增加了两个变量,一个是同一个人对每个单词的接受程度,另一个是不同人对词汇的记忆能力。有了以上两个参数,我们想设计一个系统来帮助用户复习以前可能忘记的词汇。遗忘曲线可以个性化,计算每个用户复习词汇的最佳时间更为准确。

The recent breakthrough of artificial intelligence (AI) in many fields has recently shown its impact on drone technology as well. However, most of the provided solutions either entirely rely on commercial software or provide a weak integration interface which denies the development of additional techniques. This leads us to propose a novel and efficient frame-work for the drone technology. Specifically, we introduce the multi-layer AI (MLAI) framework which allows easy integration of ad-hoc AI applications. To demonstrate the benefits of the proposed framework, we implemented deep learning models to track and detect objects based on MLAI.
最近,人工智能(AI)在许多领域的突破也对无人机技术产生了影响。然而,大多数提供的解决方案要么完全依赖于商业软件,要么提供一个弱集成接口,从而拒绝开发其他技术。这使我们提出了一种新颖而高效的无人机技术框架。具体来说,我们引入了多层人工智能(MLAI)框架,该框架允许轻松集成自组织人工智能应用程序。为了证明所提出的框架的好处,我们实现了基于MLAI的深度学习模型来跟踪和检测对象。

Motorcyclists' Head Motions Recognition by Using the Smart Helmet with Low Sampling Rate 基于低采样率智能头盔的摩托车手头部运动识别

The number of traffic incidents involving motorcyclists is on the rise; consequently research has focused on analysis of the head motions of motorcyclists to determine their level of concentration on the road while driving. These studies used three-axis accelerometers in helmets to record the acceleration signals that are detected when motorcyclists move their heads and then analyzed these signals using machine learning. However, we found that these methods are not very effective for the following reasons: (1) battery and memory capacity constraints mean that helmet sensors cannot collect acceleration data frequently, so the results cannot completely present head motions. (2) When motorcyclists are riding, the acceleration data collected by the helmets not only include the acceleration data of motorcyclist head motions but also include the acceleration data of motorcycle movement, which creates difficulties for recognition. (3) Due to the volume constraints of helmets, we cannot install GPUs or large-capacity batteries, so more complex models or deep learning models cannot be directly used for head motion recognition. (4) Head motions are smaller than body or limb motions, and most head motions do not occur periodically, which makes recognition even more difficult. To overcome these issues, this study proposed a novel machine learning method combined with a fuzzy neural network to perform motorcyclist head motion recognition with low-frequency acceleration signals collected from helmets. Experiment simulations demonstrate the validity of the proposed method.
涉及电单车驾驶者的交通事故数目不断上升;因此,研究的重点是分析摩托车手的头部运动,以确定他们在驾驶时对道路的集中程度。这些研究使用头盔上的三轴加速度计记录摩托车手移动头部时检测到的加速信号,然后使用机器学习分析这些信号。然而,我们发现这些方法并不是很有效,原因如下:(1)电池和内存容量的限制意味着头盔传感器不能频繁地收集加速度数据,因此结果不能完整地呈现头部运动。(2)摩托车骑行时,头盔采集的加速度数据不仅包括摩托车头部运动的加速度数据,还包括摩托车运动的加速度数据,这给识别带来了困难。(3)由于头盔的体积限制,我们无法安装gpu或大容量电池,因此无法直接使用更复杂的模型或深度学习模型进行头部运动识别。(4)头部运动比身体或肢体运动要小,而且大多数头部运动不是周期性发生的,这使得识别更加困难。为了克服这些问题,本研究提出了一种结合模糊神经网络的新型机器学习方法,利用从头盔收集的低频加速度信号进行摩托车手头部运动识别。实验仿真验证了该方法的有效性。

Under the big wave of artificial intelligence, one kind of critical technology is chatbot, whose virtual identity can play an important role in a virtual community. By proposing the system model of an Internet community and its chatbots, this paper designs target-monitoring (TM) intelligent agent and applies in real learning community. For a learning community platform, the system outputs can be assessment outcomes and learning attitudes, which can be transformed to linguistic variables by fuzzification. Moreover, a learning chatbot is designed with three-layered structure: fuzzified status, decision table and generated sentence. For learning, certain teaching strategies can be coded in the decision table to make chatbot generate advice sentences to learners. To prove the idea, a chatbot structure for learning monitoring is implemented within LINE community, and a real learning experiment is carried out. Moreover, such chatbot and its community system structure can be not only used in learning; an extended experiment is planned to construct a TM agent for operation management.
在人工智能的大浪潮下,聊天机器人是一种关键技术,其虚拟身份可以在虚拟社区中发挥重要作用。本文通过提出网络社区及其聊天机器人的系统模型,设计了目标监控智能体,并将其应用于真实的学习型社区。对于学习社区平台,系统输出可以是评估结果和学习态度,通过模糊化将其转化为语言变量。设计了一种学习型聊天机器人,具有模糊状态、决策表和生成语句三层结构。对于学习,可以在决策表中编码一定的教学策略,使聊天机器人生成给学习者的建议句。为了证明这一想法,在LINE社区中实现了一个用于学习监控的聊天机器人结构,并进行了真实的学习实验。而且,这种聊天机器人及其社区系统结构不仅可以用于学习;计划进行扩展实验,构建用于运营管理的TM代理。

By proposing the system model of an Internet community and its chatbots, this paper designs target-monitoring (TM) intelligent agent and applies in real learning community. For a learning community platform, the system outputs can be assessment outcomes and learning attitudes, which can be transformed to linguistic variables by fuzzification. Moreover, a learning chatbot is designed with three-layered structure: fuzzified status, decision table and generated sentence. For learning, certain teaching strategies can be coded in the decision table to make chatbot generate advice sentences to learners. To prove the idea, a chatbot structure for learning monitoring is implemented within LINE community, and a real learning experiment is carried out. Moreover, such chatbot and its community system structure can be not only used in learning; an extended experiment is planned to construct a TM agent for operation management.","PeriodicalId":259542,"journal":{"name":"2019 Twelfth International Conference on Ubi-Media Computing (Ubi-Media)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114689632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the growing new technologies and a vast variety of different jobs available to students, it is not possible to educate students with all necessary skills that they will need for different potential jobs. However, a gap between student skills and industry expectations is needed to decrease. In order to help senior students for discovering skills which are required to their intended jobs in ICT industry and improving their missing skills, we generate and provide wiki-based books based on their intended job-skills. We use two datasets, ICT jobs in labor market and ACM Computer Science 2013 (CS2013) guideline. Skills are extracted from job descriptions and keywords are extracted from knowledge units of CS2013, then those are mapped into each other. Finally, wiki-contents are extracted by using the keywords and wiki-books are generated. We discuss preliminary results and demonstrate the proposed system.
随着新技术的不断发展和各种不同的工作可供学生选择,不可能教育学生所有必要的技能,他们将需要不同的潜在工作。然而,学生技能与行业期望之间的差距需要缩小。为了帮助高年级学生发现他们在信息通信技术行业中所需要的技能,并改善他们所缺乏的技能,我们根据他们的预期工作技能制作和提供基于维基的书籍。我们使用了两个数据集,劳动力市场中的ICT工作和ACM计算机科学2013 (CS2013)指南。从CS2013的职位描述中提取技能,从知识单元中提取关键词,然后将它们相互映射。最后,利用关键词提取维基内容,生成维基图书。我们讨论了初步结果,并演示了所提出的系统。
