However, the vehicles in the cognitive vehicular network have high-speed mobility and the network topology changes frequently, which makes spectrum allocation more challenging. In this paper, the above factors are considered and a connection between the remaining available time of the primary user and the time required by the cognitive vehicle is established in our spectrum allocation model. To maximize network throughput under the heterogeneous spectrum environment, a rapid convergence algorithm that adapts to a dynamic cognitive vehicular network environment for solving this problem is necessary. Therefore, the improved adaptive binary cuckoo search (IABCS) algorithm that incorporates the simplex method into the adaptive binary cuckoo algorithm is proposed. The experimental results indicate that comparing with the original standard cuckoo search $(CS)$ algorithm and the improved particle swarm optimization (PSO) algorithm, the spectrum allocation method based on the improved adaptive cuckoo algorithm converges faster and achieves higher throughput.","PeriodicalId":375852,"journal":{"name":"2018 5th International Conference on Systems and Informatics (ICSAI)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115471700","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}

The aligned entities can be used for transferring knowledge across knowledge graphs and benefit several tasks such as cross-lingual knowledge graph construction and knowledge reasoning. This paper propose a representation learning based algorithm for embedding knowledge graph and aligning entities. In particular, considering the multi-type relations in knowledge graph, we select the alignment-task driven representative relations based on the pre-aligned entity pairs. With the help of selected relations, we embed the entities across networks into a common space by modeling entities’ head/tail are with corresponding context vectors. For entity alignment task, pre-aligned entities are adopted to facilitate the transfer of context information across the knowledges graphs. Through this way, the problem of entity embedding and alignment can be solved simultaneously under a unified framework.. Extensive experiments on two multi-lingual knowledge graphs demonstrate the effectiveness of the proposed model comparing with several state-of-the-art models.","PeriodicalId":375852,"journal":{"name":"2018 5th International Conference on Systems and Informatics (ICSAI)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123640822","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}

The string similarity query on data stream has a broad prospect of application, especially in information security area and network monitoring. Due to the characteristics of stream and limitations of computing resources, the current methods based on static dataset cannot support stream efficiently. To solve these challenges, a framework named F2SCQ (framework of string similarity continuous query) based on filtering and verifying approach is pro-posed. It adopts basic window mechanism to update the sliding window, and the improved asymmetric signature (IAS) scheme to extract signature is proposed. Moreover two new filtering algorithms: Pre-Prune Filtering (PPF) and Count Filtering on Stream (CFS) are proposed. The experiments show that F2SCQ achieves high performance over high rates data stream. Compared to q-gram and asymmetric signature scheme, IAS achieves 50% and 20% faster extraction speed and 45% and 9% less storage overhead. The proposed filtering algorithm also achieves faster filtering speed and generates fewer candidates. F2SCQ minimizes the time and space complexity.","PeriodicalId":375852,"journal":{"name":"2018 5th International Conference on Systems and Informatics (ICSAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126086449","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}

DS18B20, the in-line temperature sensor was used for temperature collection, which can be transformed into a digit directly. In wireless communication, ZigBee, the protocol stack was used for relevant modification on the application layer so as to implement wireless communication over the ZigBee protocol. The whole temperature collection process and wireless communication were all completed by the CC2530 functional node module by IAR Embedded Workbench, which was an integrated development environment. One functional node of CC2530 was designed to collect temperature and send it as a terminal node. The other functional node of CC2530 was responsible for receiving temperature as a coordinator and transmit the temperature to the STM32F103RBT6 development board by the serial port communication technology. The collected temperature can be shown on the 3.2-inch TFT LCD screen and the display drive can be completed on the STM32F103RBT6 board, on which the rotation of the stepping motor can be driven. The whole development process was implemented by the MDK software developed by Keil. The data can be transmitted between the CC2530 functional node module and the STM32F103RBT6 development board by the serial communication technology. Ultimately, the system test indicated that data can be transmitted correctly and the transmission is stable so that the greenhouse management requirement can be met.","PeriodicalId":375852,"journal":{"name":"2018 5th International Conference on Systems and Informatics (ICSAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125442875","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}

Meanwhile, it has become routine for large volumes of data to be generated, stored, and processed across geographically distributed datac enters. Network congestion generated by data transfers between networks becomes a major bottleneck to the overall performance of the system in a geo-distributed environment. Many existing methods usually process network congestion after they occurs, which does not solve the problem fundamentally. In this paper, we focus on the problem of predicting and avoiding network congestion in advance in a geo-distributed environment on Apache Spark, in terms of their job completion times. We formulate this problem as a runtime minimization problem, which is challenging to solve in practice due to a scene with different data centers. To address these challenges, we propose a model based on congestion-aware scheduling. In the model, we exploit SDN(Software-Defined Networking) to detect the data size of the data flow in advance from different data centers and then analyze the data characteristics, which predicts the flow that can generate network congestion in advance, so that we can draft two scheme for different flow. In addition, when we detect the network congestion, we choose a path with a greater bandwidth for the congestion flow. The approach can minimize network congestion, promote network utilization and improve system performance in a geo-distributed environment. As a highlight of this paper, we design and implement our proposed solution as a job scheduler based on Apache Spark, a modern data processing framework.","PeriodicalId":375852,"journal":{"name":"2018 5th International Conference on Systems and Informatics (ICSAI)","volume":"31 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120860196","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}

Recently, neural network models have been demonstrated to be capable of achieving remarkable performance in this domain. However, none of existing method can achieve excellent classification accuracy while concerning of computational cost. To solve this problem, we proposed hierarchical gated convolutional networks with multi-head attention which reduces computational cost through its two distinctive characteristics to save considerable model parameters. First, it has a hierarchical structure the same as the hierarchical structure of documents that has word-level and sentence-level, which not only benefits to classification performance but also reduces computational cost significantly by reusing parameters of the model in each sentence. Second, we apply gated convolutional network on both levels that enables our model achieved comparable performance to very deep networks with relatively shallow network depth. To further improve the performance of our model, multi-head attention mechanism is employed to differentiate more or less importance of words or sentences for better construction of document representation. Experiments conducted on the commonly used Yelp reviews datasets demonstrate that the proposed architecture obtains competitive performance against the state-of-the-art methods.","PeriodicalId":375852,"journal":{"name":"2018 5th International Conference on Systems and Informatics (ICSAI)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127987690","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}
