The main purpose is to provide proper subset features for decision tree construction in the classification task. New method with the use of “Significant Matrix” on genetic algorithm is presented. The main function is to calculate the relationship between the feature and class label assigned to a fitness value for the population. The algorithm presented important features selected by considering the class of the data and number of features for the least amount in the Significant Matrix. The next step will then update the feature number and the record number to repeat the process until a stop condition is met. Classification by decision tree is used to verify the importance of the features selected by the proposed method. The model tested with 11 different datasets. The results show that the method yields high accuracy of the classification and higher satisfaction compared to classification using artificial neural network. Experimental results show that the proposed method not only provides a higher accuracy, but also reduce the complexity by using less features of the dataset.","PeriodicalId":191620,"journal":{"name":"2013 International Computer Science and Engineering Conference (ICSEC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133094403","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 research has exposed that the design of a query and its execution technique plays an important role in the optimization of a query. There are two major categories of distributed queries in distributed database system known as Decision Support system (DSS) queries and Online Transaction Processing (OLTP) queries. In this paper the prime focus is on design and analysis of DSS queries. The selected set of DSS queries are simulated by using exhaustive enumerative technique and genetic approach under serial and parallel processing environment. The simulation results show that an exhaustive enumeration approach provides optimized solution but takes huge time for complex DSS queries (Hours, Days, Month or even Years), hence it is infeasible to implement this approach for optimizing a set of DSS queries. On the other hand genetic algorithms optimize DSS Queries very quickly but show loss in accuracy and quality of solution as compare to exhaustive enumerative approach. Further the parallel execution of the different sub operations of a DSS query significantly reduces the total cost of system resources.","PeriodicalId":191620,"journal":{"name":"2013 International Computer Science and Engineering Conference (ICSEC)","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131880882","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 real-world applications, the challenge of similarity joins arises when data sets are large. Filter and verify methods have been proposed to reduce the running time of similarity join. The prefix filtering algorithm, which is one of the filter and verify methods, filters out some dissimilar strings by examining only the prefix of strings, instead of the whole strings. In this paper, we propose the data partitioning for prefix filtering method using in similarity join. For our approach, the database is divided into partitions and prefix filtering is performed for each partition of data. This proposed algorithm supports parallelism because filtering can be done on each partition independently. Furthermore, when the dataset is partitioned into smaller sets, a proper prefix length can be determined for each data partition. This also improves the selection of candidate strings, and reduces the verify time. An experiment is performed to compare the proposed algorithm to state-of-the-art algorithms. The experiment shows that our method achieves higher performance by reducing in the number of candidate strings and parallel execution.","PeriodicalId":191620,"journal":{"name":"2013 International Computer Science and Engineering Conference (ICSEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130208293","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}
