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...
متن کاملQuerying Multiple Bioinformatics Information Sources:
Advances in Semantic Web and Ontologies have pushed the role of semantics to a new frontier: Semantic Composition of Web Services. A good example of such compositions is the querying of multiple bioinformatics data sources. Supporting effective querying over a large collection of bioinformatics data sources presents a number of unique challenges. First, queries over bioinformatics data sources ...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملQuerying Heterogeneous Information Sources Using Source Descriptions
We witness a rapid increase in the number of structured information sources that are available online, especially on the WWW. These sources include commercial databases on product information, stock market information, real estate, automobiles, and entertainment. We would like to use the data stored in these databases to answer complex queries that go beyond keyword searches. We face the follow...
متن کاملQuerying Structured Information Sources Over the Web
To provide access to distributed and heterogeneous sources, information integration systems have traditionally relied on the availability of a mediated schema, along with mappings between this schema and the schema of the source schemas. Queries posed to the mediated schema are reformulated in terms of the source schemas. On the Web, where sources are plentiful, autonomous and extremely volatil...
