A Review on Extended Online Approach for Web Data Tables Integration

Urmila Bavkar, Dr. Akhil Khare

Abstract: This review paper of ONDINE system which allows the loading and the querying of a data warehouse obtained from the Web, using an Ontological and Terminological Resource (OTR) concept. The data warehouse, composed of data tables extracted from Web documents, has been built to support existing local databases. First semiautomatic method is used to annotate data tables obtained by an OTR (Ontological and Terminological Resource). The output of this method is an XML/RDF data warehouse consists of XML documents which represent data tables with their fuzzy RDF annotations. Then used flexible querying system which allows the local databases and the data warehouse which is obtained by extracting web documents to be simultaneously and uniformly queried, using the OTR. Using SPARQL (Simple Protocol and RDF Query Language) querying language approximate answers are retrieved.

Keywords: ONDINE, OTR, data table integration, XML/RDF, fuzzy, and probabilistic reasoning, representations, data structures, and transforms, knowledge modeling
