Reconciling Schema Matching Networks Through Crowdsourcing
Schema matching is the process of establishing correspondences between the attributes of database schemas for data integration purposes. Although several automatic schema matching tools have been developed, their results are often incomplete or erroneous. To obtain a correct set of correspondences, usually human effort is required to validate the generated correspondences. This validation proce...
متن کاملReconciling Schema Matching Networks
Schema matching is the process of establishing correspondences between the attributes of schemas, for the purpose of data integration. Schema matching is often performed in a pair-wise setting, in which two given schemas are matched again each other by automatic tools. In this thesis, we instead approach the schema matching problem in a network setting, in which the two schemas to be matched do...
متن کاملOn Leveraging Crowdsourcing Techniques for Schema Matching Networks
As the number of publicly-available datasets are likely to grow, the demand of establishing the links between these datasets is also getting higher and higher. For creating such links we need to match their schemas. Moreover, for using these datasets in meaningful ways, one often needs to match not only two, but several schemas. This matching process establishes a (potentially large) set of att...
متن کاملReducing Uncertainty of Schema Matching via Crowdsourcing
Schema matching is a central challenge for data integration systems. Automated tools are often uncertain about schema matchings they suggest, and this uncertainty is inherent since it arises from the inability of the schema to fully capture the semantics of the represented data. Human common sense can often help. Inspired by the popularity and the success of easily accessible crowdsourcing plat...
متن کاملAn Improved Semantic Schema Matching Approach
Schema matching is a critical step in many applications, such as data warehouse loading, Online Analytical Process (OLAP), Data mining, semantic web [2] and schema integration. This task is defined for finding the semantic correspondences between elements of two schemas. Recently, schema matching has found considerable interest in both research and practice. In this paper, we present a new impr...
