Detecting source code plagiarism on introductory programming course assignments using a bytecode approach 使用字节码方法检测编程入门课程作业的源代码抄袭
Oscar Karnalim
Even though there are various source code plagiarism detection approaches, most of them only concern with low-level plagiarism attack with an assumption that plagiarism is only conducted by students who are not proficient in programming. However, plagiarism is often conducted not only due to student incapability, but also because of bad time management. Thus, high-level plagiarism attack should be detected and evaluated. This paper proposes source code plagiarism detection approach which can detect most introductory-programming-course plagiarism attacks at any level by utilizing low-level instructions instead of source code tokens. Several mechanisms are also introduced to improve its effectiveness such as instruction generalization, instruction reinterpretation, method-based comparison, and method linearization. Since low-level instruction is a language-dependent feature, Java is selected as target programming language with bytecode as its low-level instruction. Based on evaluation, it can be concluded that our approach is more effective to detect most plagiarism attack types than raw source code approach on introductory programming course. This evaluation is based on plagiarism attack types that are collected through controlled experiment.
尽管有各种各样的源代码抄袭检测方法,但它们大多只关注低级别的抄袭攻击,并假设只有不精通编程的学生才会进行抄袭。然而,抄袭的发生不仅是因为学生的能力不足,还因为时间管理不善。因此,高层次的剽窃攻击应该被发现和评估。本文提出了一种源代码剽窃检测方法,该方法利用低级指令代替源代码令牌,可以检测任意级别的大多数入门编程课程剽窃攻击。本文还引入了指令泛化、指令重新解释、基于方法的比较和方法线性化等机制来提高算法的有效性。由于低级指令是一种依赖于语言的特性,因此选择Java作为目标编程语言,并将字节码作为低级指令。基于评估,可以得出结论,我们的方法比编程入门课程的原始源代码方法更有效地检测大多数剽窃攻击类型。此评估是基于通过对照实验收集的抄袭攻击类型。

Implementation of face detection and recognition of Indonesian language in communication between humans and robots 人与机器人交流中印尼语人脸检测与识别的实现
Muhtadin, Achmad Rizal Muttaqin, S. Sumpeno
Communication between man and machine is a challenging subject. In general, the communication between man and machine is done with rigid language (inhuman). Many scientists are trying to create a way of communication between humans and machines charmer, more personal and interactive. This paper presents the results of research work that implements interactive communication between humans and machines (robots). Communication becomes more personal by using face detection to the speaker (human). Communication is also done with more interactive by adding the ability for robots to communicate using Indonesian language. We utilize the NAO robot as a machine that can interact with humans. We employ speech Engine System consisted of Speech to Text, dialog machine, and Text to Speech which make NAO Robot can speak and understand simple human speech in Indonesian Language. The resulted system was able to perform face detection continuously on angles of range between 0° and 30°, detect human speech accurately by 80.45%, and give response to human speech appropriately by 47.58%.
人与机器之间的通信是一门具有挑战性的学科。一般来说,人与机器之间的交流是用僵硬的语言(不人道)完成的。许多科学家正试图创造一种人与机器之间更迷人、更个性化和互动的交流方式。本文介绍了实现人与机器(机器人)之间交互通信的研究工作的结果。通过对说话人(人类)进行面部检测,交流变得更加个人化。通过增加机器人使用印尼语进行交流的能力,交流也更具互动性。我们利用NAO机器人作为一种可以与人类互动的机器。我们采用了由语音到文本、对话机和文本到语音组成的语音引擎系统,使NAO机器人能够用印尼语说话并理解简单的人类语言。该系统能够在0°~ 30°的角度范围内连续进行人脸检测,对人类语音的检测准确率为80.45%,对人类语音的响应准确率为47.58%。

Kadek Aldrin Wiguna, R. Sarno, Nurul Fajrin Ariyani
The process of Solar Farm site selection is a complex issue because it involves many criteria and many factors that are classified as problem Multi-Criteria Decision Making (MCDM). With computer technology, it is possible to analyze systematically the MCDM complex problems through computational intelligence techniques. Many methods have been developed to solve optimization problems of Solar Farm site selection such as Fuzzy AHP - PROMETHEE. However, these methods have not integrated directly into GIS software. In this research this methods will be integrated into GIS software especially ArcGIS as a toolbox. With this toolbox, determining the location of the solar farm will be more effective and easily. This research provide the methodology and decision support so that decision makers can more easily and quickly to determine the best location of solar farm.
太阳能发电场选址过程是一个复杂的问题,因为它涉及到许多标准和因素,被归类为问题多标准决策(MCDM)。利用计算机技术,通过计算智能技术对MCDM复杂问题进行系统分析成为可能。为了解决太阳能发电场选址的优化问题,已经发展了许多方法,如模糊层次分析法和PROMETHEE法。然而,这些方法并没有直接集成到GIS软件中。本研究将这些方法集成到GIS软件中,特别是ArcGIS作为工具箱。有了这个工具箱,确定太阳能发电场的位置将更加有效和容易。本研究提供了方法和决策支持,使决策者能够更容易、更快速地确定太阳能发电场的最佳位置。

Integration GLCM and geometric feature extraction of region of interest for classifying tuna 融合GLCM和感兴趣区域几何特征提取的金枪鱼分类方法
Wanvy Arifha Saputra, D. Herumurti
Image of tuna as bigeye, skipjack and yellowfin have very high color similarity, but in the texture and shape can be differentiated. It requires a method to perform feature extraction of bigeye, skipjack and yellowfin appropriately, so the results on a classification of tuna have a high accurate rate. We propose a method to integrate gray level co-occurrence matrix (GLCM) and geometric feature extraction of region of interest (ROI) for classifying tuna. To measure the texture of tuna is require making region in an image using centroid as a parameter of center boundary to help determine head, body and tail. Thus, maximally get its extraction and produce an accurate classification. The experiment results show the integration GLCM and geometric shape feature extraction is successful and classify very well the image of bigeye, skipjack and yellowfin with 86.67% accurate, 0.8% Kappa, 0.11% MAE, 0.28% RMSE, 24.71% RAE and 58.95% RRSE using 10-fold cross-validation of the entire dataset.
大眼金枪鱼、鲣鱼和黄鳍金枪鱼的图像具有非常高的颜色相似性,但在纹理和形状上可以区分。需要一种方法对大眼鱼、鲣鱼和黄鳍金枪鱼进行适当的特征提取,使金枪鱼分类结果具有较高的准确率。提出了一种将灰度共生矩阵(GLCM)与感兴趣区域几何特征提取相结合的金枪鱼分类方法。为了测量金枪鱼的纹理,需要在图像中以质心作为中心边界的参数进行区域划分,从而确定金枪鱼的头、身、尾。从而最大限度地得到其提取,并产生准确的分类。实验结果表明,结合GLCM和几何形状特征提取的方法是成功的,对大眼、鲣鱼和黄鳍的图像进行了10倍交叉验证,分类准确率为86.67%,Kappa为0.8%,MAE为0.11%,RMSE为0.28%,RAE为24.71%,RRSE为58.95%。

Dynamic wDAG Similarity algorithm can be applied to sugarcane annotation. At first, we have to make a wDAG structure of many different varieties of sugarcane. We also have to make wDAG of sugarcane that will be annotated. Then, we have to calculate the similarity between wDAG types of sugarcane that will be annotated and wDAG of all the existing types of sugarcane. This similarity calculation results will present sequence similarities ranging from the most similar to the most distant from sugarcane varieties were annotated. This Dynamic wDAG Similarity algorithm has difference compared with the previous wDAG Similarity algorithm. WDAG used in this research has the node labeled, arc labeled and arc weighted, where the weight of the arc can be changed dynamically. This research fixes the previous studies of static wDAG, in which the weight values on the arc of wDAG can not be changed. On Dynamic wDAG, the weight on each arc is based on the fuzzy calculations that show the tendency of sugarcane varieties were annotated. And the fuzzy value is calculated based on agronomic traits of sugarcane to be annotated. Leaf node is the part of wDAG that will be compared first. The similarity calculation result between the two wDAG is affected by data on a leaf node to be compared and the weights of the arcs. The result shows that this method gained the average of Precision of 96%, the average of Recall of 88.5%, and the average of Accuracy of 96%.
动态wDAG相似度算法可以应用于甘蔗标注。首先,我们要把许多不同品种的甘蔗做成一个wDAG结构。我们还需要制作甘蔗的wDAG,并进行注释。然后,我们需要计算将要标注的甘蔗的wDAG类型与所有现有甘蔗类型的wDAG的相似度。这种相似性计算结果将呈现序列相似性,从最相似的到距离最远的甘蔗品种被标注。这种动态wDAG相似度算法与以往的wDAG相似度算法相比有很大的不同。本研究使用的WDAG具有节点标记、弧标记和弧加权,其中弧的权值可以动态改变。本研究修正了以往静态wDAG研究中wDAG弧线上的权值不能改变的问题。在动态wDAG上,每个弧线上的权重是基于模糊计算的,表明甘蔗品种的趋势被注释。并根据待标注甘蔗的农艺性状计算模糊值。叶子节点是wDAG中首先比较的部分。两个wDAG之间的相似性计算结果受待比较叶节点上的数据和弧的权值的影响。结果表明,该方法的平均查准率为96%,平均查全率为88.5%,平均查准率为96%。
