Besides corrupting analysis results, such inconsistencies may compromise the functionality of applications that need to correlate information from different sources, such as auditing and fraud detection systems. The traditional approach to this problem has two steps: first, duplicates are identified in a typically semi-automatic process and, then, each group of duplicates is fused into a single consolidated representation. However, this strategy may result in information loss if records have been erroneously classified as duplicates. This article presents a case study on a different approach, which consists of using graph database systems to model similarity relationships between data objects. In this way, possible duplicates can be dynamically identified using basic operations on graphs. The study was carried out within the scope of the Controladoria Geral do Estado de Goiás, as part of the development of an application to detect evidence of fraud in public bids. Initial results indicate that the proposed approach is effective and efficient in discovering links involving possible duplicates.","PeriodicalId":348938,"journal":{"name":"Proceedings of the XV Brazilian Symposium on Information Systems","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132402927","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}

Although several data mining algorithms have been developed to extract knowledge from large databases, typically such algorithms restrict themselves to analyzing data in a single dataset, which imposes a limitation on the possibilities of exploration of the various connections between the datasets in the Web of data in search of new knowledge. To overcome this limitation, the present work proposes the MRAR+, a method for mining multirelation association rules in graphs that, unlike the methods of the state of the art, is able to identify new and useful knowledge involving resources of multiple datasets connected to the Web of data. However, the proposed method seeks to identify resources linked to other datasets that, when considered in the mining process, have the potential to increase the chances of obtaining new and useful knowledge in the analyzed dataset. MRAR+ was implemented based on the MRAR algorithm that extracts multirelation association rules in graphs. In addition, MRAR+ was applied in two case studies and has produced new and useful rules for the user, illustrating the feasibility of the proposed method for mining different datasets interconnected in the Web of Data.","PeriodicalId":348938,"journal":{"name":"Proceedings of the XV Brazilian Symposium on Information Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128670436","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}
