This paper propose to develop and evaluate a learning support system which can provide personalized feedbacks for helping learners to improve their learning ability. To support the analysis of learners' cognitive processes during learning activities, this system will collect not only their learning logs and questionnaires' responses, but also their visual biometric data (eye-movement data). Eye-tracking systems with not only eye safety advance but also precision advance will be used in this research. By analyzing all the collected data, the system will identify learners' characteristics and provide real-time feedbacks in response to their characteristics.
本文提出开发和评估一个学习支持系统,该系统可以提供个性化的反馈,帮助学习者提高学习能力。为了支持学习者在学习过程中的认知过程分析,该系统不仅会收集学习者的学习日志和问卷回答,还会收集学习者的视觉生物特征数据(眼动数据)。眼动追踪系统在提高眼睛安全性的同时也提高了眼动追踪系统的精度。通过分析所有收集到的数据,系统将识别学习者的特征,并根据他们的特征提供实时反馈。

Pub Date : 2016-07-10 DOI: 10.1109/IIAI-AAI.2016.109
Yuko Hayashi, H. Yanagimoto
We proposed a title generation method with a recurrent neural network using concepts of machine translation. The title generator consists of an encoder and a decoder and they are constructed with Long Short Term Memory, which is one of the recurrent neural networks. We construct a distributed representation of an article in the encoder and the decoder generates a title without extraction of an article. In some evaluational experiments we confirmed that our proposed method could generate appropriate titles from articles but in some articles the method generate random titles.
我们提出了一种基于递归神经网络的标题生成方法。标题生成器由编码器和解码器组成,它们由长短期记忆构成,长短期记忆是递归神经网络的一种。我们在编码器中构建文章的分布式表示,解码器生成标题而不提取文章。在一些评价实验中,我们证实了我们提出的方法可以从文章中生成合适的标题,但在一些文章中,该方法生成随机标题。

Stock Market Prediction from News on the Web and a New Evaluation Approach in Trading 基于网络新闻的股票市场预测与交易评估新方法
Pub Date : 2016-07-10 DOI: 10.1109/IIAI-AAI.2016.157

The market analysis is one of the important tasks for text mining. Many researchers have proposed methods using text information for analyzing the market. In this situation, news on the Web has an important role to predict stock prices. In this paper, we propose a method to predict the Nikkei Stock Average, which is one of the most important stock market indexes. We also focus on the evaluation of the prediction. In general, the results are evaluated by some criteria such as recall and precision rates. However, the most important point in the stock market prediction task is not always the accuracy of classifiers. We demonstrate the effectiveness of our method with simulated trading on a real stock market. We compare some strategies for the trading, and then discuss relations between the accuracy of classifiers and profit-and-loss. For the purpose, we introduce a criterion computed from the property change graph in each demo-trading. We call it CPC (Criterion based on Property Changes). By using the criterion CPC, we can easily understand the effectiveness of one-day classifiers in terms of the real trading situation.
市场分析是文本挖掘的重要任务之一。许多研究者提出了利用文本信息分析市场的方法。在这种情况下,网络上的新闻对预测股票价格具有重要作用。在本文中,我们提出了一种预测日经平均指数的方法,这是最重要的股票市场指数之一。我们还重点讨论了预测的评价。一般来说,结果是通过一些标准来评估的,比如召回率和准确率。然而,在股票市场预测任务中,最重要的一点并不总是分类器的准确性。我们通过真实股票市场的模拟交易来证明我们方法的有效性。我们比较了一些交易策略,然后讨论了分类器的准确度与盈亏之间的关系。为此,我们引入了一个从每个演示交易的属性变化图中计算出来的准则。我们称之为CPC(基于财产变化的标准)。通过使用CPC标准,我们可以很容易地了解一天分类器在真实交易情况下的有效性。

The present study aims to investigate whether and how keeping vocabulary notebooks in digital forms influence students' vocabulary learning practices, performance, and perceptions. Of particular interest to this study is the use of learner-constructed vocabulary notebooks to engage students in the process of intentional vocabulary learning, and ultimately, to enhance their vocabulary acquisition. A Computer Assisted Vocabulary Learning (CAVL) system was developed in this study to assist learners of English as a foreign language. The usage of the CAVL system involved three major steps (i.e., Select, Organize, and Integrate), which engaged learners in watching online videos to intentionally study target words, through the construction of personal vocabulary notebooks. The effectiveness of this system, in combination with the intentional vocabulary learning strategy, was evaluated through a quasi-experimental study with two groups of students from a university in Taiwan. The students' use of vocabulary notebooks, scores of vocabulary tests, individual interviews, and responses to a perception survey were closely analyzed, and the results showed the overall positive impact of the investigated strategy on vocabulary learning. The practical implications of this study are thus discussed to promote the use of digital vocabulary notebooks as an intentional learning strategy in vocabulary instruction.
本研究旨在探讨以数字形式保存词汇笔记是否以及如何影响学生的词汇学习实践、表现和认知。本研究特别感兴趣的是使用学习者构建的词汇笔记来吸引学生参与有意词汇学习的过程,并最终提高他们的词汇习得。本研究开发一套计算机辅助词汇学习系统,以协助英语学习者学习外语。CAVL系统的使用包括三个主要步骤(选择、组织和整合),通过构建个人词汇笔记本,让学习者观看在线视频,有意识地学习目标单词。通过对台湾某大学两组学生的准实验研究,评估了该系统与意向词汇学习策略相结合的有效性。通过对学生的词汇笔记使用情况、词汇测试成绩、个人访谈和感知调查结果的分析,结果显示了被调查策略对词汇学习的总体积极影响。在此基础上,探讨了本研究的实际意义,以促进数字词汇笔记本作为一种有意学习策略在词汇教学中的使用。

Eating with Eyes: Assessing the Importance of the Visual Perception of Consumers 用眼睛吃饭:评估消费者视觉感知的重要性
Pub Date : 2016-07-10 DOI: 10.1109/IIAI-AAI.2016.51

Purchasing behavior is a kind of consuming behavior caused by visual stimulation of and attraction to a consumer. In other words, consumers are visual creatures. Although existing literature has explored the influences of the senses and perception on purchasing behavior, there is very little literature deeply exploring the influence of the visual sense on dish preferences in the catering industry. This study adopted purposive sampling and importance-performance analysis. A total of 38 questionnaires were collected, and Excel 2013 was used to analyze the influences of consumers' visual preferences on their levels of love for a dish. The study results show proper color matching can effectively increase the purchase behavior of consumers. The important preference factors include color contrast, harmony, shape matching, and the space design between food and receptacle. The study results can be used as references for the operational practices of the catering industry, and as an academic basis for subsequent studies on food aesthetics by researchers and teachers.
购买行为是消费者受到视觉刺激和吸引而产生的一种消费行为。换句话说,消费者是视觉生物。虽然已有文献探讨了感官和知觉对购买行为的影响,但深入探讨餐饮业视觉对菜肴偏好影响的文献很少。本研究采用目的抽样和重要性-绩效分析。共收集了38份调查问卷,使用Excel 2013分析消费者的视觉偏好对其对某道菜的喜爱程度的影响。研究结果表明,适当的色彩搭配可以有效地提高消费者的购买行为。重要的偏好因素包括色彩对比、和谐、形状匹配以及食物与容器之间的空间设计。研究结果可为餐饮业的经营实践提供参考,也可为研究者和教师后续的食物美学研究提供学术依据。

It is important to analyze the reputation or demands for a local event, such as a school festival. The aim of this research is to develop a system that enables its users to collect and to analyze local event information from social media. In this paper, we have shown the over view and described the implementation of the proposed system. Our system extracts tweets by sentiment polarity classification and visualizes them. In this paper, we described the performance of the sentiment polarity classification and showed that the system is efficient for coordinating tweets. We collected tweets about a local event and classified them manually. The sentiment polarity classification of our system was evaluated by comparing it with the manually classified tweets. We also discussed an example of local event analysis using our system and showed the efficiency of our system.

This study attempts a comparative disciplinary analysis of a Web of Science (WoS) recorded dataset (ca. 15,000 core journal articles and reviews) of real publications for 5-years period by the research departments, dedicated to science, technology, engineering, mathematics, and medicine (STEMM), of a comprehensive university using different disciplinary schemes: Essential Science Indicators (ESI) 22 research fields, SCOPUS 27 subject areas and OECD Frascati 38 subordinate research fields. It demonstrates that assigning the publications to departments and disciplines followed by correspondence analysis and clustering of the contingency table comprising disciplinary share of publications results in enhanced understanding and visualization of the research output at different levels of disciplinary or research entities. Such exercise improves creation of publication subsets (for different research entities and disciplinary schemes) for further processing, visualization and interpretation with sophisticated bibliometric/scientometric tools including the science mapping techniques.
本研究对一所综合性大学科学、技术、工程、数学和医学(STEMM)研究部门5年来真实出版物的WoS记录数据集(约15,000篇核心期刊文章和评论)进行了学科比较分析,采用不同的学科体系:基本科学指标(ESI) 22个研究领域,SCOPUS 27个学科领域和OECD Frascati 38个下属研究领域。研究表明,将出版物分配到部门和学科,然后对包含出版物学科份额的列联表进行对应分析和聚类,可以增强对不同学科或研究实体的研究产出的理解和可视化。这种练习改进了出版物子集的创建(针对不同的研究实体和学科计划),以便使用复杂的文献计量/科学计量工具(包括科学制图技术)进行进一步处理、可视化和解释。

Due to the shrinkage of high school students and growth of the number of acceptance to universities in Japan, almost all the high school students are to be enrolled to universities, which causes various educational difficulties in universities. Taking care of students who were taught insufficiently in high schools and junior high schools is one of them. The follow-up program is aimed at helping students who need basic learning and aimed at assisting teachers who have to engage in teaching a variety of students. The follow-up systems are recognized as a part of the follow-up program, and consist of the learning check testing, follow-up program testing, and collaborative work testing. They are connected to the portfolio system which manages students' scores and behaviors. We have developed the follow-up systems using online testing systems. In the systems, many persons playing roles are involved, such as teachers, students, peer supporters, and item contributors. We adopted the item response theory to evaluate students' learning skills accurately. The systems are now successfully working.
由于日本高中学生的萎缩和大学录取人数的增长,几乎所有的高中学生都要被大学录取,这就造成了大学的各种教育困难。照顾高中和初中教育不足的学生就是其中之一。后续计划旨在帮助需要基础学习的学生,并旨在协助必须从事各种学生教学的教师。跟踪系统被认为是跟踪计划的一部分,由学习检查测试、跟踪计划测试和协同工作测试组成。它们与管理学生成绩和行为的档案系统相连。我们利用在线测试系统开发了后续系统。在系统中,许多扮演角色的人都参与其中,例如教师、学生、同伴支持者和项目贡献者。我们采用项目反应理论来准确评价学生的学习技能。这些系统现在正在成功地工作。

In this study, we developed a system that records the PC user's past work and enables the user to resume a previous task. Previously, we used screenshots to record work processes. However, this method demands a huge storage capacity. Therefore, in the proposed system, duplicate screenshots are deleted through similar-image determination. In addition, screenshots are transformed into a compressed moving image by introducing the H.264 video coding standard. Moreover, we integrate a backup system into our system to help users reach files based on their queries. The information on the user's past work is organized in Research Episode Networks, which are graphs representing relationships among events, tasks, and files. Research Episode Networks make it easier for users to search for target files.
在这项研究中,我们开发了一个系统,可以记录PC用户过去的工作,并使用户能够恢复以前的任务。以前,我们使用屏幕截图来记录工作过程。然而,这种方法需要巨大的存储容量。因此,在本文提出的系统中,通过相似图像判定来删除重复的截图。此外,通过引入H.264视频编码标准,将截图转换为压缩的运动图像。此外,我们将备份系统集成到我们的系统中,以帮助用户根据他们的查询找到文件。关于用户过去工作的信息被组织在Research Episode Networks中,这些网络是表示事件、任务和文件之间关系的图形。研究集网络使用户更容易搜索目标文件。

Previously, we used screenshots to record work processes. However, this method demands a huge storage capacity. Therefore, in the proposed system, duplicate screenshots are deleted through similar-image determination. In addition, screenshots are transformed into a compressed moving image by introducing the H.264 video coding standard. Moreover, we integrate a backup system into our system to help users reach files based on their queries.
