An OTR Driven Semiautomatic- Method for Annotations of Web Data

Abstract

The data warehouse is composed of data tables extracted from the web documents and it has been supplement to existing local data sources. The semiautomatic method is to annotate data tables by an OTR. XML/RDF data warehouse is composed of XML documents representing data tables with their fuzzy RDF annotations. This system also has flexible querying method which is to query the local data sources and data warehouses uniformly. SPARQL is used to retrieve the answers. Ontological and Terminological Resource (OTR) is made of a generic set of concepts dedicated to the data integration task an specific set of concepts and terminology dedicated to a given domain. RDF provides mechanisms for describing groups of related resources and the relationships between these resources. RDF Schema is used to define the vocabulary descriptions that are written in RDF using the terms described in this document.Web data table is both formed and also obtained from the web to form data table with which the annotation is formed.The main function is to form the data table to make the annotation and with the use of RDF relation is to be defined.Correct and relevant information obtaining to the query is an important task. This task is complex if the query terms have many meanings and occur in different varieties of domain. Fuzzy-ontology based information retrieval system that determine the semantic equivalence between terms in a query and terms in a document by relating the synonyms of query terms with those of document terms.
