Each of them partially reflect schema of the backend database. Most previous works merely studied the problem of schema matching across query interfaces of Web databases.  ...  Previous approaches ([16], [17], [21]) to matching the schemas of Web databases primarily focus on matching query interfaces (i.e., on inter-site interface schema 1 Attribute matching is the process of  ...  Existing work that addresses the problem of automatic schema matching for deep Web sources adopts the prior techniques on matching schemas of traditional databases.  ...

A unified approach for schema matching, coreference and canonicalization

Michael L. Wick, Khashayar Rohanimanesh, Karl Schultz, Andrew McCallum
2008 Proceeding of the 14th ACM SIGKDD international conference on Knowledge discovery and data mining - KDD 08  
The automatic consolidation of database records from many heterogeneous sources into a single repository requires solving several information integration tasks.  ...  Systems that do tackle multiple integration problems traditionally solve each independently, allowing errors to propagate from one task to another.  ...  However, data integration is a challenging problem. Even the task of merging two databases with similar schemas about the same realworld entities is non-trivial.  ...

An online bibliography on schema evolution

Erhard Rahm, Philip A. Bernstein
2006 SIGMOD record  
We briefly motivate and present a new online bibliography on schema evolution, an area which has recently gained much interest in both research and practice.  ...  The growing importance of such problems has prompted recent work on generic metadata management, e.g., schema matching and model management.  ...  Software evolution The generation of a new software version shares many of the problems of schema evolution. Instead of schemas, we have program interfaces or class hierarchies.  ...

The Mathematical Model of Hybrid Schema Matching based on Constraints and Instances Similarity

Edhy Sutanta, Erna Kumalasari, Rosalia Arum
2019 International Journal of Advanced Computer Science and Applications  
The more matching criteria used in the schema matching provide better mapping results. The model developed is limited to schema matching processes in the relational model database.  ...  Based on the test results, a hybrid schema matching model is more effective than the constraints-based method or instance-based method run individually.  ...  ACKNOWLEDGMENT The authors would like to thanks the Directorate of Research and Community Service, Directorate General of Research and Development Strengthening at the Ministry of (IJACSA) International  ...

Relational data mapping in MIQIS

George H. L. Fletcher, Catharine M. Wyss

Conjoint Data Mining of Structured and Semi-structured Data

Qi H. Pan, Fedja Hadzic, Tharam S. Dillon
2008 2008 Fourth International Conference on Semantics, Knowledge and Grid  
This problem has become more important with the growing amount of semi-structured data often found in XML repositories, web logs, biological databases, etc.  ...  Once an optimized method has been formulated, the process of data mining can be implemented in a conjoint manner. This paper investigates a way in which this challenging problem can be tackled.  ...  Fig. 3 , it is important to realize that in each of those steps, for example, Schema Matching, we mean matching between the schema for the structured database and the XML schema.  ...
