Background: Question-answer (QA) is a popular method to seek health-related information and biomedical data. Such questions can refer to more than one medical entity (multi-label) so determining the correct tags is not easy. The question classification (QC) mechanism in a QA system can narrow down the answers we are seeking.Objective: This study develops a multi-label classification using the heterogeneous ensembles method to improve accuracy in biomedical data with long text dimensions.Methods: We used the ensemble method with heterogeneous deep learning and machine learning for multi-label extended text classification. There are 15 various single models consisting of three deep learning (CNN, LSTM, and BERT) and four machine learning algorithms (SVM, kNN, Decision Tree, and Naïve Bayes) with various text representations (TF-IDF, Word2Vec, and FastText). We used the bagging approach with a hard voting mechanism for the decision-making.Results: The result shows that deep learning is more powerful than machine learning as a single multi-label biomedical data classification method. Moreover, we found that top-three was the best number of base learners by combining the ensembles method. Heterogeneous-based ensembles with three learners resulted in an F1-score of 82.3%, which is better than the best single model by CNN with an F1-score of 80%.Conclusion: A multi-label classification of biomedical QA using ensemble models is better than single models. The result shows that heterogeneous ensembles are more potent than homogeneous ensembles on biomedical QA data with long text dimensions.Keywords: Biomedical Question Classification, Ensemble Method, Heterogeneous Ensembles, Multi-Label Classification, Question Answering
背景:问答(QA)是寻求健康相关信息和生物医学数据的一种流行方法。这些问题可能涉及多个医疗实体(多标签),因此确定正确的标签并不容易。QA系统中的问题分类(QC)机制可以缩小我们所寻求的答案。目的:利用异构集成方法开发一种多标签分类方法,以提高长文本维度生物医学数据的准确率。方法:采用异构深度学习和机器学习相结合的集成方法进行多标签扩展文本分类。有15种不同的单一模型,由三种深度学习(CNN, LSTM和BERT)和四种机器学习算法(SVM, kNN, Decision Tree和Naïve Bayes)组成,具有各种文本表示(TF-IDF, Word2Vec和FastText)。我们使用了套袋方法和硬投票机制来进行决策。结果:作为单一的多标签生物医学数据分类方法,深度学习比机器学习更强大。此外,结合集成方法,我们发现前三名是基础学习器的最佳数量。基于异质性的三个学习器集成的f1得分为82.3%,优于CNN的最佳单一模型f1得分为80%。结论:采用集成模型对生物医学质量保证的多标签分类效果优于单一模型。结果表明,在长文本维数的生物医学QA数据上,异构集成比同质集成更有效。关键词:生物医学问题分类,集成方法,异构集成,多标签分类,问题回答

Background: Twitter is one of the most used social media, with 310 million active users monthly and 500 million tweets per day. Twitter is not only used to talk about trending topics but also to share information about accidents, fires, traffic jams, etc. People often find these updates useful to minimize the impact.Objective: The current study compares the effectiveness of three deep learning methods (CNN, RCNN, CLSTM) combined with neuroNER in classifying multi-label incidents.Methods: NeuroNER is paired with different deep learning classification methods (CNN, RCNN, CLSTM).Results: CNN paired with NeuroNER yield the best results for multi-label classification compared to CLSTM and RCNN.Conclusion: CNN was proven to be more effective with an average precision value of 88.54% for multi-label incidents classification. This is because the data we used for the classification resulted from NER, which was in the form of entity labels. CNN immediately distinguishes important information, namely the NER labels. CLSTM generates the worst result because it is more suitable for sequential data. Future research will benefit from changing the classification parameters and test scenarios on a different number of labels with more diverse data.Keywords: CLSTM, CNN, Incident Classification, Multi-label Classification, RCNN
背景:Twitter是最常用的社交媒体之一,每月有3.1亿活跃用户,每天有5亿条推文。Twitter不仅用于讨论热门话题,还用于分享有关事故、火灾、交通堵塞等信息。人们经常发现这些更新有助于减少影响。目的:比较CNN、RCNN、CLSTM三种深度学习方法结合neuroNER对多标签事件进行分类的有效性。方法:将NeuroNER与不同的深度学习分类方法(CNN、RCNN、CLSTM)配对。结果:与CLSTM和RCNN相比,CNN与NeuroNER配对在多标签分类方面的效果最好。结论:CNN对多标签事件分类的平均准确率为88.54%,具有较好的分类效果。这是因为我们用于分类的数据来自NER,它是以实体标签的形式出现的。CNN立即区分重要信息,即NER标签。CLSTM产生的结果最差,因为它更适合于顺序数据。未来的研究将受益于改变分类参数和在不同数量的标签上使用更多样化的数据的测试场景。关键词:CLSTM, CNN,事件分类,多标签分类,RCNN

Background: Ocean surface currents need to be monitored to minimize accidents at ship crossings. One way to predict ocean currents—and estimate the danger level of the sea—is by finding out the currents’ velocity and their future direction.Objective: This study aims to predict the velocity and direction of ocean surface currents.Methods: This research uses the Elman recurrent neural network (ERNN). This study used 3,750 long-term data and 72 short-term data.Results: The evaluation with Mean Absolute Percentage Error (MAPE) achieved the best results in short-term predictions. The best MAPE of the U currents (east to west) was 14.0279% with five inputs; the first and second hidden layers were 50 and 100, and the learning rate was 0.3. While the best MAPE of the V currents (north to south) was 3.1253% with five inputs, the first and second hidden layers were 20 and 50, and the learning rate was 0.1. The ocean surface currents’ prediction indicates that the current state is from east to south with a magnitude of around 169,5773°-175,7127° resulting in a MAPE of 0.0668%.Conclusion: ERNN is more effective than single exponential smoothing and RBFNN in ocean current prediction studies because it produces a smaller error value. In addition, the ERNN method is good for short-term ocean surface currents but is not optimal for long-term current predictions.Keywords: MAPE, ERNN, ocean currents, ocean currents’ velocity, ocean currents’ directions
背景:需要监测海洋表面洋流,以尽量减少船舶过境时的事故。预测洋流和估计海洋危险程度的一种方法是找出洋流的速度和未来的方向。目的:预测海洋表面洋流的速度和方向。方法:本研究采用Elman递归神经网络(ERNN)。这项研究使用了3750个长期数据和72个短期数据。结果:平均绝对百分比误差(MAPE)评价在短期预测中效果最好。5路输入时,U型电流(东向西)的最佳MAPE为14.0279%;第一层和第二层隐藏层分别为50层和100层,学习率为0.3。5个输入时,V电流(从北向南)的最佳MAPE为3.1253%,第一层和第二层隐藏层分别为20层和50层,学习率为0.1。海流预测表明,海流状态为自东向南,震级约为169、5773°~ 175、7127°,MAPE为0.0668%。结论:相对于单指数平滑和RBFNN, ERNN在海流预测研究中误差值较小,具有较好的效果。此外,ERNN方法对短期海流预报效果较好,但对长期海流预报效果不佳。关键词:MAPE, ERNN,洋流,洋流速度,洋流方向

Background: Inventory policy highly influences Supply Chain Management (SCM) process. Evidence suggests that almost half of SCM costs are set off by stock-related expenses.Objective: This paper aims to minimise total inventory cost in SCM by applying a multi-agent-based machine learning called Reinforcement Learning (RL).Methods: The ability of RL in finding a hidden pattern of inventory policy is run under various constraints which have not been addressed together or simultaneously in previous research. These include capacitated manufacturer and warehouse, limitation of order to suppliers, stochastic demand, lead time uncertainty and multi-sourcing supply. RL was run through Q-Learning with four experiments and 1,000 iterations to examine its result consistency. Then, RL was contrasted to the previous mathematical method to check its efficiency in reducing inventory costs.Results: After 1,000 trial-error simulations, the most striking finding is that RL can perform more efficiently than the mathematical approach by placing optimum order quantities at the right time. In addition, this result was achieved under complex constraints and assumptions which have not been simultaneously simulated in previous studies.Conclusion: Results confirm that the RL approach will be invaluable when implemented to comparable supply network environments expressed in this project. Since RL still leads to higher shortages in this research, combining RL with other machine learning algorithms is suggested to have more robust end-to-end SCM analysis. Keywords: Inventory Policy, Multi-Echelon, Reinforcement Learning, Supply Chain Management, Q-Learning
背景:库存政策高度影响供应链管理(SCM)过程。有证据表明,几乎一半的供应链管理成本是由与股票相关的费用抵消的。目的:本文旨在通过应用称为强化学习(RL)的基于多代理的机器学习来最小化SCM中的总库存成本。方法:在多种约束条件下运用强化学习方法发现库存策略的隐藏模式,而这些约束条件在以往的研究中没有同时或共同解决。这些包括有能力的制造商和仓库,对供应商的订单限制,随机需求,交货时间的不确定性和多源供应。RL通过Q-Learning进行了四次实验和1000次迭代,以检查其结果的一致性。然后,将RL与之前的数学方法进行对比,检验其降低库存成本的效率。结果:在1000次试错模拟之后,最引人注目的发现是,强化学习可以比数学方法更有效地执行,在正确的时间下最佳订单数量。此外,这一结果是在复杂的约束和假设下获得的,而这些约束和假设在以往的研究中没有同时进行模拟。结论:结果证实,RL方法在实施到本项目中表达的可比供应网络环境时将是非常宝贵的。由于强化学习在本研究中仍然存在较高的不足,因此建议将强化学习与其他机器学习算法相结合,以获得更强大的端到端SCM分析。关键词:库存政策,多梯队,强化学习,供应链管理,q -学习

Background: Human face is a biometric feature. Artificial Intelligence (AI) called Artificial Neural Network (ANN) can be used in recognising such a biometric feature. In ANN, the learning process is divided into two: supervised and unsupervised learning. In supervised learning, a common method used is Backpropagation, while in the unsupervised learning, a common one is Kohonen Self Organizing Map (KSOM). However, the application of Backpropagation and KSOM need to be adjusted to improve the performance.Objective: In this study, Backpropagation and KSOM algorithms are rewritten to suit face image recognition, applied and compared to determine the effectiveness of each algorithm in solving face image recognition.Methods: In this study, the methods used and compared in the case of face image recognition are Backpropagation dan Kohonen Self Organizing Map (KSOM) Artificial Neural Network (ANN).Results: The smallest False Acceptance Rate (FAR) value of Backpropagation is 28%, and KSOM is 36%, out of 50 unregistered face images tested. While the smallest False Rejection Rate (FRR) value of Backpropagation is 22%, and KSOM is 30%, out of 50 registered face images. The fastest time for the training process using the backpropagation method is 7.14 seconds, and the fastest time for recognition is 0.71 seconds. While the fastest time for the training process using the KSOM method is 5.35 seconds, and the fastest time for recognition is 0.50 seconds.Conclusion: Backpropagation method is better in recognising face images than KSOM method, but the training process and the recognition process by KSOM method are faster than Backpropagation method due to the hidden layers. Keywords: Artificial Neural Network (ANN), Backpropagation, Kohonen Self Organizing Map (KSOM), Supervised learning, Unsupervised learning 
背景:人脸是一种生物特征。被称为人工神经网络(ANN)的人工智能(AI)可用于识别这种生物特征。在人工神经网络中,学习过程分为监督学习和无监督学习。在监督学习中,常用的方法是反向传播(Backpropagation),而在无监督学习中,常用的方法是Kohonen自组织映射(KSOM)。但是,为了提高性能,需要调整反向传播和KSOM的应用。目的:在本研究中,将反向传播和KSOM算法改写为适合人脸图像识别的算法,并进行应用和比较,以确定每种算法在解决人脸图像识别中的有效性。方法:在人脸图像识别的情况下,使用并比较了反向传播和Kohonen自组织映射(KSOM)人工神经网络(ANN)方法。结果:在50张未配准人脸图像中,反向传播的最小错误接受率(FAR)值为28%,KSOM值为36%。而在50张配准的人脸图像中,反向传播的最小错误拒绝率(FRR)为22%,KSOM为30%。反向传播方法的训练过程最快时间为7.14秒,识别过程最快时间为0.71秒。而KSOM方法训练过程的最快时间为5.35秒,识别的最快时间为0.50秒。结论:反向传播方法对人脸图像的识别效果优于KSOM方法,但由于存在隐藏层,KSOM方法的训练过程和识别过程都比反向传播方法快。关键词:人工神经网络,反向传播,Kohonen自组织映射(KSOM),监督学习,无监督学习

Background: Commuting time is highly influenced by traffic congestion. System dynamics simulation can help identify the cause of traffic problems to improve travel time efficiency.Objective: This study aims to reduce traffic congestion and minimise commuting time efficiency using system dynamics simulation and scenarios. The developed scenarios implement the Bus Rapid Transit (BRT) and trams projects in the model.Methods: System dynamics simulation is used to analyse the transport system in Surabaya and the impact of BRT and trams project implementation in the model in order to improve commuting time and to reduce congestion.Results: From the simulation results, with the implementation of BRT and tram projects along with highway expansion, traffic congestion is predicted to decline by 24-44%.  With the reduction of traffic congestion, travel time efficiency is predicted to improve by 11-28%. On the contrary, implementation of BRT and tram project without highway expansion is predicted to increase the traffic congestion by 5% in the initial year of implementation, then traffic congestion is predicted to decline by 2% in 2035.Conclusion: Based on the scenarios, transport project implementation such as BRT and trams should be accompanied with improvement of infrastructure. Further research is needed to develop a more comprehensive transportation system to capture a broader view of the problem. Keywords: Model, Simulation, System Dynamics, Traffic Congestion, Travel Time 
背景:交通拥堵对通勤时间的影响很大。系统动力学仿真可以帮助识别交通问题的原因,提高出行效率。目的:通过系统动力学模拟和场景分析,研究如何减少交通拥堵和最小化通勤时间效率。所开发的场景在模型中实现了快速公交(BRT)和有轨电车项目。方法:采用系统动力学仿真的方法,对泗水市的交通系统进行分析,并对模型中BRT和有轨电车项目实施的影响进行分析,以改善通勤时间,减少拥堵。结果:从模拟结果来看,随着BRT和有轨电车项目的实施以及高速公路的扩建,预计交通拥堵将下降24-44%。随着交通拥堵的减少,预计出行时间效率将提高11-28%。相反,在不扩建公路的情况下实施BRT和有轨电车项目,预计在实施的头一年,交通拥堵将增加5%,到2035年,预计交通拥堵将下降2%。结论:基于情景,BRT和有轨电车等交通项目的实施应伴随着基础设施的改善。需要进一步的研究来开发一个更全面的运输系统,以从更广泛的角度来看待这个问题。关键词:模型,仿真,系统动力学,交通拥堵,出行时间

On the contrary, implementation of BRT and tram project without highway expansion is predicted to increase the traffic congestion by 5% in the initial year of implementation, then traffic congestion is predicted to decline by 2% in 2035.Conclusion: Based on the scenarios, transport project implementation such as BRT and trams should be accompanied with improvement of infrastructure. Further research is needed to develop a more comprehensive transportation system to capture a broader view of the problem. Keywords: Model, Simulation, System Dynamics, Traffic Congestion, Travel Time ","PeriodicalId":16185,"journal":{"name":"Journal of Information Systems Engineering and Business Intelligence","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78878270","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}

Background: Standard operating procedure (SOP) is a series of business activities to achieve organisational goals, with each activity carried to be recorded and stored in the information system together with its location (e.g., SCM, ERP, LMS, CRM). The activity is known as event data and is stored in a database known as an event log.Objective: Based on the event log, we can calculate the fitness to determine whether the business process SOP is following the actual business process.Methods: This study obtains the event log from a terminal operating system (TOS), which records the dwelling time at the container port. The conformance checking using token-based replay method calculates fitness by comparing the event log with the process model.Results: The findings using the Alpha algorithm resulted in the most traversed traces (a, b, n, o, p). The fitness calculation returns 1.0 were produced, missing, and remaining tokens are replied to each of the other traces.Conclusion: Thus, if the process mining produces a fitness of more than 0.80, this shows that the process model is following the actual business process. Keywords: Conformance Checking, Dwelling time, Event log, Fitness, Process Discovery, Process Mining
背景:标准作业程序(SOP)是为实现组织目标而进行的一系列业务活动,每项活动都要记录并存储在信息系统中,并连同其位置(例如,SCM、ERP、LMS、CRM)。该活动称为事件数据,并存储在称为事件日志的数据库中。目的:根据事件日志计算适应度,判断业务流程SOP是否遵循实际业务流程。方法:本研究从终端操作系统(TOS)获取事件日志,记录集装箱港口的停留时间。使用基于令牌的重播方法的一致性检查通过将事件日志与流程模型进行比较来计算适合度。结果:使用Alpha算法的结果产生了遍历次数最多的轨迹(a, b, n, o, p)。产生了适应度计算返回值1.0,丢失了,剩余的标记被回复到每个其他轨迹。结论:因此,如果流程挖掘产生的适应度大于0.80,则表明流程模型遵循实际业务流程。关键词:一致性检查,停留时间,事件日志,适应度,过程发现,过程挖掘

Background: To remain relevant in the customer-oriented market, hospitals must pay attention to the quality of services and meet customers' expectations from admission to discharge stage. For an outpatient customer, pharmacy is the last unit visited before discharge. It is likely to influence patient satisfaction and reflect the quality of hospital's service. However, at certain hospitals, the waiting time is long. Resources need to be deployed strategically to reduce queue time. Objective: This research aims to arrange the number of staff (pharmacists and workers) in each station in the pharmacy outpatient service to minimise the queue time.Methods: A discrete simulation method is used to observe the waiting time spent at the pharmacy. The simulation run is valid and effective to test the scenario. Results: It is recommended to add more personnel for the non-compounding medicine and packaging to reduce the waiting time by 22.41%Conclusion: By adding personnel to non-compounding and packaging stations, the system performance could be improved. Cost-effectiveness analysis should be done to corroborate the finding. Keywords: Discrete Event Simulation, Hospital, Outpatient Service, Pharmacy Unit, System AnalysisBackground: To remain relevant in the customer-oriented market, hospitals must pay attention to the quality of services and meet customers' expectations from admission to discharge stage.

Background: Peer-to-peer (P2P) lending platform is one of key disruptive business models in financial technology. It bridges lenders and borrowers directly. Researchers have studied the leverage mechanism behind the P2P lending platform.Objective: This research proposes an enhanced technology acceptance model (TAM) to investigate how consumers embrace P2P lending platforms using quality of service and perceived risk as drivers of trust.Methods: This research uses structural equation modeling (SEM) to test the hypothesised connections between the latent variables.Results: The findings show that users' trust, perceived usefulness, and perceived ease of use in P2P lending platforms significantly influence attitudes towards adoption. Meanwhile, consumers' perceived risk in using P2P lending platforms is unaffected by the quality of service.Conclusion: The estimated model is consistent with the results shown in previous studies.  The findings of the current research are useful for fine-tuning platform marketing plans and putting strategic goals into actions. For future research, we suggest including more variables to better understand the adoption intention of P2P lending platforms.Keywords: Adoption intention, Peer-to-peer lending, Structural equation modeling, Technology acceptance model

Background: The introduction of Kartu Prakerja (Pre-employment Card) Programme, henceforth KPP, which was claimed to have launched in order to improve the quality of workforce, spurred controversy among members of the public. The discussion covered the amount of budget, the training materials and the operations brought out various reactions. Opinions could be largely divided into groups: the positive and the negative sentiments.Objective: This research aims to propose an automated sentiment analysis that focuses on KPP. The findings are expected to be useful in evaluating the services and facilities provided.Methods: In the sentiment analysis, Support Vector Machine (SVM) in text mining was used with Radial Basis Function (RBF) kernel. The data consisted of 500 tweets from July to October 2020, which were divided into two sets: 80% data for training and 20% data for testing with five-fold cross validation.Results: The results of descriptive analysis show that from the total 500 tweets, 60% were negative sentiments and 40% were positive sentiments. The classification in the testing data show that the average accuracy, sensitivity, specificity, negative sentiment prediction and positive sentiment prediction values were 85.20%; 91.68%; 75.75%; 85.03%; and 86.04%, respectively.Conclusion: The classification results show that SVM with RBF kernel performs well in the opinion classification. This method can be used to understand similar sentiment analysis in the future. In KPP case, the findings can inform the stakeholders to improve the programmes in the future. Keywords: Kartu Prakerja, Sentiment Analysis, Support Vector Machine, Text Mining, Radial Basis Function
