Fog computing is a potential solution for the Internet of Things in close connection with things and end-users. Fog computing will easily transfer sensitive data without delaying distributed devices. Moreover, fog computing is more in real-time streaming applications, sensor networks, IoT which need high speed and reliable internet connectivity. Due to the heterogeneous and distributed characteristics, finley distributing the task with computation offloading is a challenging task. Developing an efficient QoE-aware application mapping policy is challenging due to the different user interests. The energy consumption would usually increase after such an algorithm and policy are implemented. In this paper, we enhanced the future from the previous QoE paper by proposing a computation offloading algorithm. The proposed algorithm is to prevent overloading on fog devices. Our proposed solution has been evaluated and compared with other existing solutions, the results show that our proposed solution performs better in terms of execution time, energy consumption, and network usage.
雾计算是物联网的一个潜在解决方案,它与物和最终用户紧密相连。雾计算可以轻松地传输敏感数据,而不会延迟分布式设备。此外,雾计算更多地用于实时流应用,传感器网络,物联网,这些应用需要高速可靠的互联网连接。由于任务的异构性和分布式特点,对具有计算负载的任务进行精确分配是一项具有挑战性的任务。由于用户兴趣的不同,开发有效的qos感知应用程序映射策略具有挑战性。这样的算法和策略实施后,能耗通常会增加。在本文中,我们通过提出一种计算卸载算法来增强前一篇QoE论文的未来。提出的算法是为了防止雾设备过载。我们提出的解决方案已经进行了评估,并与其他现有解决方案进行了比较,结果表明,我们提出的解决方案在执行时间、能耗和网络使用方面表现更好。

The mobile edge computing (MEC) model is featured by the ability to provision elastic computing resources close to user requests at the edge of the internet. This paradigm moves traditional digital infrastructure close to mobile networks and extensively reduces application latency for mobile computing tasks like online gaming and video streaming. Nevertheless, it remains a difficulty to provide a effective and performance-guaranteed edge service offloading and migration in the MEC environment. Most existing contributions in this area consider task offloading as a offline decision making process by exploiting transient positions of mobile requesters as model inputs. In this work instead, we develop a predictive-trajectory-aware and online MEC task offloading strategy. Simulations based on real-world MEC deployment datasets and a campus mobile trajectory datasets clearly illustrate that our approach outperforms state-of-the-art ones in terms of effective service rate and migration overhead.
移动边缘计算(MEC)模型的特点是能够在互联网边缘提供接近用户请求的弹性计算资源。这种模式使传统的数字基础设施更接近移动网络,并大大减少了在线游戏和视频流等移动计算任务的应用程序延迟。然而,在MEC环境中提供有效且有性能保证的边缘服务卸载和迁移仍然是一个困难。该领域的大多数现有贡献都将任务卸载视为一种离线决策过程,通过利用移动请求者的临时位置作为模型输入。在这项工作中,我们开发了一种预测轨迹感知和在线MEC任务卸载策略。基于真实世界MEC部署数据集和校园移动轨迹数据集的模拟清楚地表明,我们的方法在有效服务率和迁移开销方面优于最先进的方法。

In order to enhance the customer experience, it is important not only to provide functions, but also to respond to changes in environments and requirements. It is a difficult task to evaluate and manage which function with different locations and contents is most valuable to the user's experience without using computationally time-consuming optimization calculations. To address this, this paper is focusing on self-adaptive software technology. The authors built a software adaptation mechanism that can be immediately calculated online using a performance characteristic map and threshold judgment with a learning function and sequential updates. The results confirmed the effectiveness of the mechanism in an application that supports personnel exchange events.

The process of intrusion detection usually involves identifying complex intrusion signatures from a huge repository. This requires a complex model that can identify these signatures. This work presents a deep learning based neural network model that can perform effective intrusion detection on network transmission data. The proposed multi-layered deep learning network is composed of multiple hidden processing layers in the network that makes it a deep learning network. Detection using the deep network was observed to exhibit effective performances in detecting the intrusion signatures. Experiments were performed on standard benchmark datasets like KDD CUP 99, NSL-KDD, and Koyoto 2006+ datasets. Comparisons were performed with state-of-the-art models in literature, and the results and comparisons indicate high performances by the proposed algorithm.

The map matching method gets simpler with higher precision positioning systems, but because the positioning framework is still not sufficiently precise or too costly for marginal map matching in practice, it is still a hot research domain. Several researchers have worked on map-matching methods and reported their finding of in-depth studies of domain. This literature review provides extensive information on the above map-matching methods related to digital maps with respect to convergence and outline the problems, information sources, as well as future demands identified by industry/society. It focuses on past research work approaches, implementations, capabilities, and their weaknesses using linear search and citation chaining. Finally, this work concludes with recommendations of the future direction of research and ideas to develop new algorithms for advanced applications.

This paper proposes an effective and optimal sentiment classification method named Penguin Rider optimization algorithm-based Deep Recurrent Neural Network (PeROA-based Deep RNN) to perform sentiment classification using political reviews. However, the proposed PeROA is developed by incorporating the Penguins Search Optimization Algorithm (PeSOA) with the Rider Optimization Algorithm (ROA). The sentiment classification process is progressed using the Deep RNN classifier, which in turn generate the optimal solution based on the fitness measure. Accordingly, the function with the minimal error value is accepted as the best solution. The sentiment-based features enable the classifier to perform better classification result with respect to the sentiment tweets. However, the proposed PeROA-based Deep RNN obtained better performance using the metrics, like accuracy, sensitivity, specificity, recall, F-measure, thread score, NPV, FPR,FNR and FDR with the values of 92.030%, 92.030%, 92.235%, 92.030%, 92.030%, 92.030%, 92.030%, 3.105%, 3.11%, and 3.105%, respectively.
本文提出了一种有效且最优的情感分类方法——基于企鹅骑手优化算法的深度递归神经网络(PeROA-based Deep RNN),利用政治评论进行情感分类。该算法将企鹅搜索优化算法(PeSOA)与骑手优化算法(ROA)相结合。使用深度RNN分类器进行情感分类过程,然后根据适应度度量生成最优解。因此,接受误差值最小的函数作为最佳解。基于情感的特征使分类器能够对情感推文执行更好的分类结果。然而,基于peroa的深度RNN在准确率、灵敏度、特异性、召回率、F-measure、线程得分、NPV、FPR、FNR和FDR等指标上表现更好,分别为92.030%、92.030%、92.235%、92.030%、92.030%、92.030%、3.105%、3.11%和3.105%。

Task-oriented dialogue systems aim to engage in interactive dialogue with people to ultimately complete specific tasks. Typical application domains include ticket booking, online shopping, and healthcare providing. Medical dialogue systems can interact with patients, provide initial clinical advice, and improve the efficiency and quality of healthcare services. However, current medical dialogue systems lack the ability to utilize domain knowledge. This paper extracts regular domain knowledge as well as medical process knowledge from clinical guidelines to improve the performance of dialogue systems. Regular knowledge is used to generate accurate responses for a given input, and process knowledge is used to steer the conversation. The authors divide the task of multi-turn conversation generation into four sub-tasks and propose a 4-layer knowledge-based process-aware dialogue model that incorporates the domain knowledge to generate responses. Results indicate that the approach can lead medical conversations actively while providing accurate responses.
面向任务的对话系统旨在与人进行互动对话,最终完成特定的任务。典型的应用领域包括订票、在线购物和医疗保健服务。医疗对话系统可以与患者互动,提供初步临床建议,提高医疗服务的效率和质量。然而,目前的医学对话系统缺乏利用领域知识的能力。本文从临床指南中提取常规领域知识和医疗过程知识,以提高对话系统的性能。常规知识用于为给定的输入生成准确的响应,流程知识用于引导对话。作者将多回合对话生成任务划分为4个子任务,提出了一种基于知识的4层过程感知对话模型,该模型结合领域知识生成响应。结果表明,该方法可以在提供准确响应的同时积极引导医学对话。

Results indicate that the approach can lead medical conversations actively while providing accurate responses.","PeriodicalId":54936,"journal":{"name":"International Journal of Web Services Research","volume":"26 1","pages":"1-22"},"PeriodicalIF":1.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87959705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tracking of spatial objects in indoor location-based services is becoming increasingly important for many applications. However, much research has focused only on querying and indexing in indoor spaces without considering the indoor variations. Therefore, this paper presents an indoor framework which includes data structures of indoor environments comprised of various building features and multiple floors. Moreover, the indoor framework includes indoor navigation and routing for both directed and undirected indoor environments, indoor density which takes into account the room capacity, and movement trajectories in single and multi-floor structures. Using synthetic data, the authors conducted extensive experiments to evaluate the proposed framework. The results show that this indoor framework can be implemented efficiently and effectively.
在基于室内位置的服务中对空间对象的跟踪对于许多应用来说变得越来越重要。然而,许多研究只关注室内空间的查询和索引,而没有考虑室内的变化。因此,本文提出了一个室内框架,该框架包括由各种建筑特征和多层组成的室内环境的数据结构。此外,室内框架包括有向和无向室内环境的室内导航和路由、考虑房间容量的室内密度以及单层和多层结构中的运动轨迹。利用合成数据,作者进行了广泛的实验来评估所提出的框架。结果表明,该室内框架可以有效地实现。
