Semantic matching of schemas in heterogeneous data sharing systems is time consuming and error prone. Existing mapping tools employ semi-automatic techniques for mapping two schemas at a time. In a large-scale scenario, where data sharing involves a large number of data sources, such techniques are not suitable. We present a new robust mapping method which creates a mediated schema tree from a ...

We view match as an operator that takes two graph-like structures (e.g., XML schemas) and produces a mapping between the nodes of these graphs that correspond semantically to each other. Semantic schema matching is based on the two ideas: (i) we discover mappings by computing semantic relations (e.g., equivalence, more general); (ii) we determine semantic relations by analyzing the meaning (con...

The integration of independently developed data sources poses many problems, which are the result of several types of heterogeneity. One of the most daunting challenges is schema matching, which is the semi-automatic process of detecting semantic relationships between attributes in heterogeneous schemata. Various solutions that exploit schema information or extract specific features from attrib...

Schema integration is a central task for data integration. Over the years, many tools have been developed to discover correspondences between schemas elements. Some of them produce an integrated schema. However, the schema matching community lacks some metrics which evaluate the quality of an integrated schema. Two measures have been proposed, completeness and minimality. In this paper, we exte...

Prison Break solves the established practice (5), widely used for database migration and ontology where similar domain concepts may not be be identifiable via linguistic. Database / Oracle Data...

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...

Schema matching is the process of establishing correspondences between the attributes of database schemas for data integration purpose. Although several schema matching tools have been developed, their results are often incomplete or erroneous. To obtain correct attribute correspondences, in practice, human experts edit the mapping results and fix the mapping problems. As the scale and complexi...
