报告题目:Normalization of Duplicate Records from Multiple Sources

报告人:Weiyi Meng ProfessorDepartment of Computer Science State University of New York at BinghamtonU.S.A.





Data consolidation is a challenging issue in data integration. The value of data explodes when it is linked and fused with other data from numerous (Web) sources. The promise of Big Data hinges upon addressing several big data integration challenges, such as record linkage at scale, real-time data fusion, and integrating Deep Web. Although much work has been conducted on these problems, there is limited work on creating a uniform, standard record from a group of records corresponding to the same real-world entity. Such a record representation, referred to as normalized record, is important for both front-end and back-end applications. We refer to this task as record normalization. In this talk, I will introduce our recent work in formalizing the record normalization problem and present an in-depth analysis of normalization granularity levels (e.g., record, field, and field-value-component) and of normalization forms (e.g., typical versus complete). I will also introduce a comprehensive framework for computing the final normalized record. The proposed framework includes a large number of record normalization strategies.
