Kernelization of Eigenspace-Based Fuzzy C-Means for Topic Detection on Indonesian News 基于特征空间的模糊c均值核化印尼新闻主题检测
Mukti Ari, H. Murfi
Topic detection is practical methods to find a topic in a collection of documents. One of the methods is a clustering-based method whose centroids are interpreted as topics, i.e., eigenspace-based fuzzy c-means (EFCM). The clustering process of the EFCM method is performed in a smaller dimensional Eigenspace. Thus, the accuracy of the clustering process may be reduced. In this paper, we use the kernel method so that the clustering process is performed in a higher dimensional space without transforming data into that space. Our simulations show that this kernelization improves the accuracies of EFCM in term of interpretability scores for Indonesian news.
主题检测是在文档集合中查找主题的实用方法。其中一种方法是基于聚类的方法,其质心被解释为主题,即基于特征空间的模糊c均值(EFCM)。EFCM方法的聚类过程是在较小维度的特征空间中进行的。因此,聚类过程的准确性可能会降低。在本文中,我们使用核方法使聚类过程在高维空间中进行,而不需要将数据转换到该空间中。我们的模拟表明,这种核化在印度尼西亚新闻的可解释性分数方面提高了EFCM的准确性。

Grouping of Provinces in Indonesia According to Digital Divide Index 根据数字鸿沟指数对印度尼西亚各省进行分组
Nori Wilantika, D. I. Sensuse, Septian Bagus Wibisono, Pamuji Lasiyanto Putro, Aslon Damanik
National development, especially in Information and Communication Technology (ICT), contributes to the economic progress of a country, not least Indonesia. But the uneven development of ICT among provinces in Indonesia has resulted in a digital divide. In order to bridge the gap, a guideline is needed to indicate which provinces need more attention in ICT development. This research aims to measure and to classify the level of the digital divide that occurred in 34 provinces of Indonesia using Digital Divide Index (DIDIX) introduced by Hüsing and Selhofer. The result indicated that there was 1 province with the low digital divide rate, 19 provinces with the medium digital divide rate, and 14 provinces with the high digital divide.
国家的发展,特别是在信息和通信技术(ICT)方面的发展,有助于一个国家的经济进步,尤其是印度尼西亚。但是,印度尼西亚各省之间信息通信技术发展的不平衡导致了数字鸿沟。为了缩小差距,需要制定一项指导方针,指出哪些省份在信息通信技术发展方面需要更多的关注。本研究旨在使用h sing和Selhofer提出的数字鸿沟指数(DIDIX)来衡量和分类印度尼西亚34个省的数字鸿沟水平。结果表明:全省数字鸿沟率低的省份有1个,中等数字鸿沟率的省份有19个,高数字鸿沟率的省份有14个。

Mining Customer Opinion for Topic Modeling Purpose: Case Study of Ride-Hailing Service Provider 基于主题建模目的的客户意见挖掘——以网约车服务提供商为例
Reggia Aldiana Wayasti, I. Surjandari, Zulkamain
The popularity of ride-hailing services in the form of smartphone application as a transportation solution has become center of attention. The convenience offered has made many people use it in daily life and discuss it on social media. As a result, ride-hailing service providers utilize social media for capturing customers' opinions and marketing their services. If customers' statements about ride-hailing services are analyzed further, service providers can get insight for evaluating their services to meet customers' satisfaction. Text mining approach can be useful to analyze large number of posts and various writing styles to extract hidden information. Furthermore, by applying topic modeling, service providers can identify the important points that were spoken by customers without previously giving label or category to the text. Latent Dirichlet Allocation was used in this study to extract topics based on the posts from ride-hailing customers published on Twitter. This study used 40 parameter combinations for LDA to get the best one to obtain the topics. Based on the perplexity value, there were 9 topics discussed by customers in their posts including the top words in each topic. The output of this study can be used for the service providers to evaluate and improve the services.
作为一种交通解决方案,以智能手机应用为形式的网约车服务的流行成为人们关注的焦点。它提供的便利使许多人在日常生活中使用它,并在社交媒体上讨论它。因此,网约车服务提供商利用社交媒体来捕捉客户的意见,并营销他们的服务。如果进一步分析客户对网约车服务的陈述,服务提供商可以获得评估其服务以满足客户满意度的洞察力。文本挖掘方法可以用于分析大量的帖子和各种写作风格,以提取隐藏信息。此外,通过应用主题建模,服务提供者可以识别客户所说的要点,而无需事先为文本提供标签或类别。本研究使用Latent Dirichlet Allocation从网约车客户在Twitter上发布的帖子中提取话题。本研究使用40个参数组合进行LDA,以获得最佳的组合来获得主题。根据困惑度值,客户在他们的帖子中讨论了9个话题,包括每个话题的热门词。本研究的结果可供服务提供者评估及改善服务。

Rejuvenation Action Model for Application Software 应用软件的年轻化动作模型
Zaiha Nadiah Zainal Abidin, J. Yahaya, A. Deraman, Zuriani Hayati Abdullah
The rapid growth of software development forces the owner and developer of a software to develop a good quality software and relevant for use in a long period of time without affecting the operation and high maintenance cost. Previous studies revealed that software lifespan can be very short as short as 1–3 years. At the same time, the lifespan depends on the quality of the software. Software ageing is defined as deterioration of quality gradually and further decline the relevancy of the software to the users and environment. Therefore, a software ageing framework is demanded to measure and assess the ageing of software product grounded on certain ageing factors. Based on the ageing assessment result, the rejuvenation actions will be suggested to improve the quality of the software and help prevent quality degradation of the product. Software rejuvenation model proposed in this paper is an effort to assist the owners of the software in order to know the relevancy level of the software in their operating environment. If the software is facing ageing, the rejuvenation action can be applied and executed to maintain and upgrade the software to become ‘young and healthy’.
软件开发的快速发展,迫使软件的所有者和开发人员在不影响运行和高维护成本的情况下,开发出高质量且适合长期使用的软件。以前的研究表明,软件的生命周期可能很短,短至1-3年。同时,寿命取决于软件的质量。软件老化被定义为软件质量逐渐恶化,软件与用户和环境的相关性进一步下降。因此,需要一个基于某些老化因素的软件老化框架来度量和评估软件产品的老化。根据老化评估结果,提出返老还童的措施,以提高软件质量,防止产品质量下降。本文提出的软件复兴模型是为了帮助软件所有者了解软件在其操作环境中的关联程度。如果软件面临老化,可以应用和执行年轻化行动,维护和升级软件,使其变得“年轻和健康”。

Mining Web Log Data for Personalized Recommendation System 面向个性化推荐系统的Web日志数据挖掘
Asma Rosyidah, I. Surjandari, Zulkarnain
Increase in number of internet users in Indonesia boosts the development of e-commerce platform. Whereas potential access to a larger and more diverse customer base is generally viewed as an opportunity, it can also represent increase in competition among e-commerce platforms. Hence, e-commerce needs to develop sophisticated strategies to attract and retain customers, one of which is done through personalization in web services. Recommendation system, one form of web service personalization in e-commerce platform, predicts user preferences and helps them find products that they may be interested in by implementing web mining techniques. This empirical research investigated user web log data which illustrate behavior and implicit preferences of customers in one of e-commerce in Indonesia to predict user preferred product category in their future request. In this study, model-based recommendation system was built based on users' activity in a session and site type using C5.0 algorithm of decision tree technique. Top N recommendations were given based on probability-based ranking of categories resulted from probability estimation of the decision tree.
印尼网民数量的增加促进了电子商务平台的发展。虽然潜在的更大、更多样化的客户群通常被视为一个机会,但它也可能意味着电子商务平台之间的竞争加剧。因此,电子商务需要制定复杂的策略来吸引和留住客户,其中之一就是通过web服务中的个性化来完成。推荐系统是电子商务平台中web服务个性化的一种形式,它通过实现web挖掘技术,预测用户的偏好,帮助用户找到自己可能感兴趣的产品。本实证研究调查了用户网络日志数据,这些数据说明了印度尼西亚电子商务中客户的行为和隐性偏好,以预测用户在未来请求中偏好的产品类别。本研究采用决策树技术的C5.0算法,基于用户在一个会话中的活跃度和站点类型,构建了基于模型的推荐系统。根据决策树的概率估计对类别进行基于概率的排序,给出Top N个推荐。

Analysis of Non-Negative Double Singular Value Decomposition Initialization Method on Eigenspace-based Fuzzy C-Means Algorithm for Indonesian Online News Topic Detection 基于特征空间的模糊c均值算法非负双奇异值分解初始化方法在印尼语在线新闻主题检测中的应用
Raden Trivan Sutrisman, H. Murfi
The rapid increasing of online news in Indonesia creates the need for news analysis to obtain information as fast as possible. Topics are basic components that are often used to analyze data in the textual forms, such as the news article. By using topic modeling, topics can be detected automatically on large news documents which are difficult to perform manually. One of the topic modeling that can be used is the clustering-based method, i.e., Eigenspace-based Fuzzy C-Means (EFCM). The common initialization method of EFCM is random. However, this random initialization usually produces different topics for each run. Therefore, we consider Non-Negative Double Singular Value Decomposition (NNDSVD) as an initialization method of EFCM. Besides the advantage of non-randomness, our simulations show that the NNDSVD method gives better accuracies in term of interpretability score than the random method.
印尼在线新闻的快速增长,使得新闻分析成为了尽快获取信息的必要条件。主题是通常用于分析文本形式(如新闻文章)中的数据的基本组件。通过主题建模,可以实现对大型新闻文档的主题自动检测,这是人工难以完成的任务。可以使用的主题建模方法之一是基于聚类的方法,即基于特征空间的模糊c均值(EFCM)。EFCM常用的初始化方法是随机的。但是,这种随机初始化通常会为每次运行产生不同的主题。因此,我们将非负双奇异值分解(NNDSVD)作为EFCM的一种初始化方法。除了非随机性的优势外,我们的模拟表明,NNDSVD方法在可解释性评分方面比随机方法具有更高的精度。

Development of E-Kanban Application Using Stock-Needs Rule Prioritizing Policy to Reduce 0-Ick for Pharmaceutical Warehousing 基于库存需求规则优先级策略的电子看板应用开发以减少药品仓储0-Ick
Raihan Razafuad, A. Ridwan, B. Santosa
The company that being analyzed is PT XYZ, which is a multinational pharmaceutical company and grow to be as an agent and distributor. PT. XYZ receives large quantities of goods and place it in the reserve area. However, in the order picking activity, the goods mostly delivered to the customer in small quantity, so the goods are stored in two types, the products that stored on the pallet that been placed on the rack (reserve area) and the product in the form of retail that came from bulky and placed into the bin (forward area) by the replenishment operator. The problem that PT XYZ faced is not only when the product doesn't exist, but also when the product is not replenished to the forward area. There is so much product left in the reserve area and haven't been replenished to the forward area because there is lack of coordination between the replenishment operator and the picker. One of the strategies to speed up order picking and to deal with small quantities in the order lines is to operate a forward area from which the most demanded products can be picked quickly. To address this issue, this research objective is to reduce the stockout (0-picks) by maintaining the stocks using the e-Kanban system and stock priority for the replenishment process at pharmaceutical directorate in warehouse of PT XYZ.
被分析的公司是PT XYZ,这是一家跨国制药公司,并成长为代理商和分销商。PT. XYZ接收大量货物并将其放置在储备区域。然而,在订单拣货活动中,货物大多是少量交付给客户的,因此货物的存储分为两种,一种是储存在货架上的托盘上的产品(储备区),另一种是由补货操作员以零售的形式将来自大件的产品放入箱中(转发区)。PT XYZ面临的问题不仅在于产品不存在,还在于产品没有补充到forward区域。由于补货操作人员和拣货人员之间缺乏协调,导致储备区剩余的产品太多,没有补货到前进区。加快取货速度和处理订单线中小批量订单的策略之一是操作一个前沿区域,从那里可以快速取到最需要的产品。为了解决这个问题,本研究的目标是通过使用电子看板系统和库存优先级来维持库存,从而减少缺货(0-拣货)。

Social Network Performance Analysis and Content Engagement on Indonesia's E-Commerce 印尼电子商务的社会网络绩效分析与内容参与
A. Alamsyah, A. Utami
The prosperousness of open data has the advantage to provide strategies for a business to find a new highly effective approach to understand market behavior. Performance is a recap of results over a given period of time. The effort to stay competitive among similar e-commerce sites is measured by their performance in the content characteristics strategy to engage the customer on social network services or social media, such as Facebook. Most companies use similar strategy to support Social Customer Relationship Management (SCRM) effort and their content engagement value. E-commerce is included in the sector which also utilizes social media to interact with their customers. Hence, using social media data provides a new practical way to measure SCRM effort. The more active SCRM networks generally have positive impact on the company performance. In this paper, we use Social Network Analysis (SNA) method and descriptive analysis to evaluate the SCRM and to measure content performance based on engagement value (EV). We use Tokopedia and Bukalapak as case studies, during observation period from 1st September 2017 to 30th September 2017 on Facebook page.
开放数据的繁荣为企业找到新的高效方法来理解市场行为提供了策略。业绩是一段时间内业绩的概括。在类似的电子商务网站中保持竞争力的努力是通过他们在社交网络服务或社交媒体(如Facebook)上吸引客户的内容特征策略中的表现来衡量的。大多数公司使用类似的策略来支持社会客户关系管理(Social Customer Relationship Management, SCRM)工作及其内容参与价值。电子商务也包括在利用社交媒体与客户互动的部门。因此,使用社会媒体数据提供了一种新的实用方法来衡量SCRM的效果。越活跃的供应链管理网络通常对公司绩效有积极的影响。在本文中,我们使用社会网络分析(SNA)方法和描述性分析来评估SCRM,并基于参与价值(EV)来衡量内容绩效。我们使用Tokopedia和Bukalapak作为案例研究,在2017年9月1日至2017年9月30日的Facebook页面观察期。

Design and Implementation Adaptive Intrusion Prevention System (IPS) for Attack Prevention in Software-Defined Network (SDN) Architecture 软件定义网络(SDN)体系结构中自适应入侵防御系统的设计与实现
Rifqi Fauzan Pratama, N. Suwastika, M. A. Nugroho
Intrusion Prevention System (IPS) is a tool for securing networks from any malicious packet that could be sent from specific host. IPS can be installed on SDN network that has centralized logic architecture, so that IPS doesnt need to be installed on lots of nodes instead it has to be installed alongside the controller as center of logic network. IPS still has a flaw and that is the block duration would remain the same no matter how often a specific host attacks. For this reason, writer would like to make a system that not only integrates IPS on the SDN, but also designs an adaptive IPS by utilizing a fuzzy logic that can decide how long blocks are based on the frequency variable and type of attacks. From the results of tests that have been done, SDN network that has been equipped with adaptive IPS has the ability to detect attacks and can block the attacker host with the duration based on the frequency and type of attacks. The final result obtained is to make the SDN network safer by adding 0.228 milliseconds as the execute time required for the fuzzy algorithm in one process.
入侵防御系统(IPS)是一种保护网络免受来自特定主机的恶意数据包攻击的工具。IPS可以安装在集中式逻辑架构的SDN网络上,不需要安装在很多节点上,而只需安装在控制器旁边作为逻辑网络的中心。IPS仍然有一个缺陷,那就是无论特定主机攻击的频率如何,阻止持续时间都会保持不变。出于这个原因,作者想做一个系统,不仅集成在SDN上的IPS,而且还设计了一个自适应的IPS,利用模糊逻辑,可以根据频率变量和攻击类型来决定块的长度。从已经完成的测试结果来看,配置了自适应IPS的SDN网络具有检测攻击的能力,可以根据攻击的频率和类型对攻击者主机进行持续时间的阻断。最终得到的结果是,通过在一个进程中增加0.228毫秒作为模糊算法所需的执行时间,使SDN网络更安全。
