Evaluation of researchers is a big issue in institutional research. We propose a method for quantitatively evaluating the stage of young, middle and senior researchers focusing on the role of the last author in co-authored papers. We trace the two time series of the number of published papers and the ratio of the last authored papers among them of each researcher. We conducted experiments on 84 researchers of ICT related graduate school of a university in Japan, and on 50 researchers who published papers in 15 highly evaluated international conferences and 5 international journals. We analyzed 3360 articles in the first case and 13138 articles in the second case. We test three different approaches: cross tables, portfolios and bar graphs.
科研人员的评价是机构研究中的一个重要问题。我们提出了一种定量评价年轻、中级和高级研究人员的阶段的方法,重点关注共同作者论文中最后一位作者的作用。我们追踪了每位研究者发表论文数量和最后发表论文比例的两个时间序列。我们对日本某大学ICT相关研究生院的84名研究人员,以及在15个高评价国际会议和5个国际期刊上发表论文的50名研究人员进行了实验。我们在第一个案例中分析了3360篇文章,在第二个案例中分析了13138篇文章。我们测试了三种不同的方法:交叉表、组合图和条形图。

Robust Agricultural Supply Chain Management with Various Random and Fuzzy Parameters 基于随机和模糊参数的农业供应链稳健管理
Pub Date : 2017-11-15 DOI: 10.1109/IIAI-AAI.2017.88

This paper proposes a robust model of multiperiod agricultural supply chain to consider both maximizing the total profit and minimizing the environmental load with random and fuzzy parameters. Our proposed model is formulated as a fuzzy and stochastic, multiobjective and multiperiod programming problem, and hence, it is hard to solve the formulated problem directly without setting a specific random distribution and a specific membership function. Therefore, a distribution-free approach based on sample mean and variance derived from received data, which does not assume any specific random distributions and membership functions, is introduced to apply our proposed model to various uncertain conditions. In addition, deterministic equivalent transformations are also introduced to obtain the optimal solution efficiently using the scenario-based approach.
本文提出了一个考虑总利润最大化和环境负荷最小化的多周期农业供应链鲁棒模型,该模型具有随机和模糊参数。我们提出的模型是一个模糊、随机、多目标、多周期的规划问题,因此,如果不设定特定的随机分布和特定的隶属函数,很难直接解决所提出的问题。因此,引入了一种基于接收数据的样本均值和方差的无分布方法,该方法不假设任何特定的随机分布和隶属函数,将我们提出的模型应用于各种不确定条件。此外,还引入确定性等价变换,利用基于场景的方法有效地获得最优解。

What sort of care should a university take for student-athletes? To answer the question and to consider the future educational strategy are one of big issues for many universities. The authors created a questionnaire which consists of 77 questions with multiple choice form. We collected the responses from 100 student-athletes and 141 other students. The present paper analyzed the characteristic features of student-athletes. We considered 312 kinds of combination of question items and the response choices as words and the questionnaire record of a student as a document written in those words. Then we applied the text mining method SVM (support vector machine) and feature selection. As the result, we confirmed that we can distinguish student-athletes from other students with 90% accuracy based on 16 characteristic features such as (a) they spend much time on athlete club and not on study, (b) they want to work for economically rich life, (c) they think that it is advantageous to job hunting or graduate school if they have good grades and (d) they have less interests on international perspective in campus life.
大学应该对学生运动员采取什么样的照顾?如何回答这个问题,如何思考未来的教育战略,是许多高校面临的重大问题之一。作者制作了一份由77个选择题组成的问卷。我们收集了100名学生运动员和141名其他学生的回复。本文分析了大学生运动员的特点。我们将312种问题项和回答选项的组合作为单词,将学生的问卷记录作为用这些单词写成的文档。然后应用支持向量机(SVM)和特征选择方法进行文本挖掘。结果,我们证实,我们可以区分学生运动员与其他学生有90%的准确率基于16个特征,如(a)他们花了很多时间在运动员俱乐部,而不是在学习上,(b)他们想要为经济富裕的生活而工作,(c)他们认为如果他们有好的成绩,这对找工作或研究生院是有利的,(d)他们在校园生活中对国际视野的兴趣较少。

Enhancing AR-based Science Exploration through Learning Cycle 通过学习周期增强基于ar的科学探索
Pub Date : 2017-11-15 DOI: 10.1109/IIAI-AAI.2017.44
Ming-Puu Chen, Jih-Wei Hsu
The purpose of this study was to explore whether employing a learning cycle model helps students science exploration within an AR-based environment. Two types of guiding strategies were implemented within the learning cycle, including the procedural guidance and the question guidance. A pilot test was conducted to examine the design of AR-based science exploration using a learning cycle framework and the effect of type of guidance on participants learning performance and attitudes. The results revealed that when learning from the augmented-reality environment, the question-guidance group achieved better knowledge application performance than the procedural-guidance group and learners of both groups showed positive attitudes toward the employed learning activity.

Pub Date : 2017-11-15 DOI: 10.1109/IIAI-AAI.2017.122

POI recommendation aims to recommend places which users have not visited before. In this paper, we proposed a POI recommendation method using location similarity, which assumes that people may be interested in the places that are similar with the places that they have been to before. In order to calculate the similarity of locations, we proposed a novel method using time slots. Every two hours can be considered as a time slot. In other words, one day can be segmented into 12 time slots. For each location, the check-in times in each time slot can be collected. These check-in times can form a vector, which can be used to calculate the similarity of two locations. According to the similarity, the score of each unvisited locations can be calculated and sorted. Finally, the POI recommendation can be generated from the top-n unvisited locations. The experiment results show that the proposed method is effective.
POI推荐的目的是推荐用户以前没有去过的地方。在本文中,我们提出了一种基于位置相似性的POI推荐方法,该方法假设人们可能对与他们以前去过的地方相似的地方感兴趣。为了计算位置的相似度,我们提出了一种利用时隙的方法。每两个小时可以被视为一个时间段。换句话说,一天可以被分割成12个时间段。对于每个地点,可以收集每个时间段的入住时间。这些签入时间可以形成一个向量,可以用来计算两个位置的相似性。根据相似性,可以计算出每个未访问位置的得分并进行排序。最后,POI推荐可以从前n个未访问的位置生成。实验结果表明,该方法是有效的。

This paper describes a method of predicting the rutting depth by introducing Adam and dropout into MLP of neural network and GRU of recurrent neural net that can handle time series data. We built a model to predict the current rutting depth from the past rutting 3 years ago. We compared RMSE with the multiple regression model (MLR), which is most frequently used as a regression problem for the time variation of rutting depth. As a result, RMSE decreased in the order of MLR, MLP, GRU. The difference between GRU and RMSE of MLR was about 10%.

Pricing Strategies and Decisions in a Bertrand Competition with Markov Process 具有马尔可夫过程的Bertrand竞争中的定价策略与决策
Pub Date : 2017-11-15 DOI: 10.1109/IIAI-AAI.2017.28
Cheng-Han Wu
In this paper, we consider that consumers have memory about their previous purchases, and thus consumers switching behavior is associated with the gap of consumer perception. In such an environment, we investigate the interaction of the periodically pricing strategies between a brand manufacturer and a generic manufacturer, who sell homogeneous consumable products in the market, in a two-period supply chain. We formulate consumers Markovian switching behavior by using utility functions to obtain market demand for each manufacturer. Subsequently, we derive the manufacturers equilibrium pricing decisions and profits. Then, we resort to the numerical analysis to explore the parametric effects on the equilibrium results in order to provide the managerial insights.
在本文中,我们认为消费者对之前的购买行为有记忆,因此消费者的转换行为与消费者感知的差距有关。在这种环境下,我们研究了两期供应链中销售同质消费品的品牌制造商和非专利制造商之间的周期性定价策略的相互作用。我们利用效用函数来表述消费者的马尔可夫转换行为,从而得到各厂商的市场需求。在此基础上,推导出制造商的均衡定价决策和利润。然后,我们通过数值分析来探讨参数对均衡结果的影响,以提供管理见解。

Scientific exhibition in Taiwan has been held by National Taiwan Science Education Center for more than 55 years, more than 15,000 works has been accumulated. It also becomes a famous competition for K-12 students. In order to provide recommendation of research topic to the participating students, domain experts require the growth topic and related industry from the past works. However, with the long history of the scientific exhibition, the domain experts cannot interpret all of the works in the short term. Therefore, through the computer to explore and summarize a large number of works becomes an emerging technology. In this study, we applied text-mining technology, and designed an expert rules as a computer-enabled methodology to explore the correlation between scientific exhibition and industry in the earth science and physics category. In the result, you can observe the computer programming and real estate development industries were the most growing research topic in scientific exhibition.
台湾科学展由国立台湾科学教育中心举办超过55年,累积作品超过15,000件。它也成为K-12学生的著名比赛。为了给参赛学生提供研究课题的推荐,领域专家需要从过去的作品中获得成长课题和相关行业。然而,由于科学展览的历史悠久,领域专家无法在短期内解释所有的作品。因此,通过计算机来探索和总结大量的作品成为一项新兴的技术。本研究运用文本挖掘技术,设计专家规则作为计算机支持的方法,探讨地球科学与物理类科学展览与工业的相关性。结果,你可以观察到计算机编程和房地产开发行业是科学展览中最受欢迎的研究课题。

Using Self-Explanation and Ontology for Providing Proper Feedbacks in a Programming Environment 在编程环境中使用自我解释和本体提供适当的反馈
Pub Date : 2017-11-15 DOI: 10.1109/IIAI-AAI.2017.136

To help programmer gaining sound concepts of a programming language and boost their problem solving ability, this study constructs a programming environment, which, based on the self-explanation strategy, gives proper feedbacks for the programmers of C++language. The embedded self-explanation strategy guides the environment which, when programmers gets compilation errors, gives extended examples for the programmers and ask them for self-explanations on the inference of the error after they study the examples. An algorithm developed in this study compares the self-explanation sentence from a programmer with base strings, established and organized into an ontology by programing experts, and finds possible errors on the explanation, which lead to his/her possible misconceptions. Based on the results, the environment manages to feedback proper learning material and extended examples for programmers to correct their possible misconceptions. This study builds an ontology of C++ concepts class hierarchy with class properties and instances being possible misconceptions and the learning material feedbacks. The possible misconceptions are collected from actual programming practices in several pilot experiments joined by programmers of college students. The final experiment involves 13 college students who use the system for actual programming.

为了帮助程序员获得良好的编程语言概念,提高他们解决问题的能力,本研究构建了一个编程环境,该环境基于自我解释策略,对c++语言的程序员进行适当的反馈。嵌入式自解释策略引导环境,当程序员遇到编译错误时,向程序员提供扩展示例,并要求他们在学习示例后对错误的推理进行自我解释。本研究开发了一种算法,将程序员的自我解释句与编程专家建立并组织成本体的基本字符串进行比较,找出解释上可能存在的错误,从而导致程序员可能产生的误解。基于结果,环境设法反馈适当的学习材料和扩展示例,以便程序员纠正他们可能的误解。本研究建立了一个c++概念类层次的本体,类属性和实例是可能的误解,学习材料反馈。这些可能存在的误解是从大学生程序员参加的几个试点实验的实际编程实践中收集的。最后的实验涉及13名大学生,他们使用该系统进行实际编程。环境记录学生的编程活动,分析学生对错误的自我解释,并给予适当的反馈,经过编程专家的验证,平均准确率达到84.7%。本研究的显著特点是采用了开放性问题式的自我解释句要求,这在同类研究中尚属罕见。本研究开发的所有方案和算法都可以作为其他领域建立具有自我解释学习策略的系统的方法。

The embedded self-explanation strategy guides the environment which, when programmers gets compilation errors, gives extended examples for the programmers and ask them for self-explanations on the inference of the error after they study the examples. An algorithm developed in this study compares the self-explanation sentence from a programmer with base strings, established and organized into an ontology by programing experts, and finds possible errors on the explanation, which lead to his/her possible misconceptions. Based on the results, the environment manages to feedback proper learning material and extended examples for programmers to correct their possible misconceptions. This study builds an ontology of C++ concepts class hierarchy with class properties and instances being possible misconceptions and the learning material feedbacks. The possible misconceptions are collected from actual programming practices in several pilot experiments joined by programmers of college students. The final experiment involves 13 college students who use the system for actual programming. The environment records students programming activities, analyzes their self-explanations on errors, and gives proper feedbacks, which, after verified by programming experts, reaches an average accuracy of 84.7%.
