Web query classification (QC) algorithms have been widely studied to improve the accuracy and meet users' demands. Some QC algorithms convert queries into vectors and use SVM or CRF model as the classifier. However, with the volume of data increasing, the time consumed significantly increases. In this paper, we propose a method in which we split the queries into words and convert queries into a graph, after that, we adopt a liner equation as the classifier. Experimental results exhibit that our method has similar accuracy but higher efficiency compared with the existing methods. Our method can decrease the training time by 10% compared with the SVM algorithm, and also outperform the CRF model.","PeriodicalId":198938,"journal":{"name":"2015 12th Web Information System and Application Conference (WISA)","volume":"306 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115874717","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}

By analyzing the massive news of different information sources and language origins, we come up with a basic theory model and its algorithm on news, which is capable of intelligent collection, quick access, deduplication, correction and integration with news' backgrounds. Furthermore, we can find out connections between news and readers' interest. So we can achieve a real-time and on-demand news feed as well as provide a theoretical basis and verification of scientific problems on real-time processing of massive information. Finally, the simulation experiment shows that the multilingual news matching technology could give more help to distinguish the similar news in different languages than the traditional method.","PeriodicalId":198938,"journal":{"name":"2015 12th Web Information System and Application Conference (WISA)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115484929","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}

This framework bridges the information gap between network stack layers and makes it possible to process a web request always within one CPU core from the NIC (network interface card) to the application process, which avoid cache misses and CPU core switches. Experiments show that with this optimization, server applications perform and scale better. Unlike previous optimization, server applications can gain noticeable performance improvement while their source codes remain unmodified, which is a significant requirement in the production environment.","PeriodicalId":198938,"journal":{"name":"2015 12th Web Information System and Application Conference (WISA)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123979683","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 model detects the rules in a fast way using an algorithm based on rule service first, and then it resolves the conflicts segment by using action constraint strategy. And then it runs the rule merging algorithm in a set of rules with no anomalies based on service. Finally, the experimental results show that merging efficiency is outperformed compared with other similar rule merging models.

Thus, the Web service composition which consists of these services will be necessarily random of the QoS. The requirements of the QoS of Web service composition may not be certainly satisfied. We use a simulation approach named Importance Sampling to analyze the QoS probability of Web service composition in stochastic PERT network. In this paper, we propose a relatively simple distribution function and introduce a weighting function to ensure that the estimating of the target distribution function is an unbiased estimation. We conduct a comparison of Importance Sampling technique with Monte Carlo simulation about the rationality and the operation efficiency based on the actual QoS data of Web services by experiment. The experimental results prove that the Importance Sampling technique has better precision and higher efficiency than Monte Carlo simulation.","PeriodicalId":198938,"journal":{"name":"2015 12th Web Information System and Application Conference (WISA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126887769","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}

It is indispensable to address how to make a trade-off between availability and partition tolerance for a bank as it favors the consistency in the distributed system. In this research, we conduct two case studies to address the question using two transaction logs collected from a bank in China. We mainly analyze the table dependency and the table concurrency, and find that (1) it is arduous to partition the data in the database system associated with ACID properties, (2) in-memory architecture for updating transactions may be an alternative for building a transaction processing system.","PeriodicalId":198938,"journal":{"name":"2015 12th Web Information System and Application Conference (WISA)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121455482","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}

In addition, based on the main idea of MCARD, we also present a new VM placement algorithm named MPlace, which is able to efficiently increase the resource utilization through properly using the migration constraint.

Based on the gettable electric data from some areas, this paper proposed an integral system which can predict risky customers according to the various scenarios. In the system, the Random Forest (RF) model and Extreme Learning Machine (ELM) model are integrated that can effectively analyze the obvious features of the risky customers and predict the potential risky customers.
