Integrating Autonomous Heterogeneous Information Sources

Type Embedding for Integrating Heterogeneous Information Sources

Today's information society needs application speciic up to date information. The electronically available data is organized in a rapidly changing variety of sources like databases, WWW sites, le systems, etc. We need to dynamically integrate the heterogeneous data in order to provide consistent information for a speciic application. Our approach to solve this problem is a mediating system, con...

Combining schema and instance information for integrating heterogeneous data sources

Determining the correspondences among heterogeneous data sources, which is critical to integration of the data sources, is a complex and resource-consuming task that demands automated support. We propose an iterative procedure for detecting both schema-level and instance-level correspondences from heterogeneous data sources. Cluster analysis techniques are used first to identify similar schema ...

Integrating Web Information Sources

When researching a topic, users often need different kinds of information which are provided by different information sources. In developing the SINGLESOURCE application, we are building a framework for accessing multiple sources, both for querying several sources simultaneously and viewing the results in a hierarchy of related documents. We first discuss our approach to querying multiple sourc...

Querying Heterogeneous Information Sources

We witness a rapid increase in the number of structured information sources that are available online, especially on the WWW. These sources store interrelated data on topics such as product information, stock market information, entertainment , etc. We would like to use the data stored in these databases to answer complex queries that go beyond keyword searches. We describe the Information Mani...
