Information Integration for Heterogeneous Data Sources
Information Retrieval from heterogeneous information systems is required but challenging at the same as data is stored and represented in different data models in different information systems.Information integrated from heterogeneous data sources into single data source are faced upon by major challenge of information transformationwere in different formats and constraints in data transformati...
متن کاملIntegration of Heterogeneous Information Sources
This thesis presents a framework for integrating information from multiple heterogeneous sources. The framework consists of an HTML extension called OHTML and the W3Graph query language. OHTML adds to HTML semantic tags. The W3Graph query language is a query language for semistructured data that we designed for querying OHTML pages. We designed OHTML to enrich HTML pages with semantic informati...
متن کاملIBHIS: Integration Broker for Heterogeneous Information Sources
Effective use of heterogeneous, distributed information in a coherent, integrated fashion has long been a 'holy grail'. The UK Health and Social care domain is an example where a global view is needed to facilitate decision making, whilst having ethical and legal concerns. The IBHIS project aims to provide an integrated broker that enables coherent use of a set of distributed, heterogeneous dat...
متن کاملImproving integration quality for heterogeneous data sources
This work considers a problem of integrating heterogeneous semi–structured data sources with the purpose of estimating integration quality (IQ). During the integration of such data sources the IQ estimation plays an important role, because correspondences and dependencies within and across the sources are not completely known, the schema or semantics might be missing, which leads to results wit...
متن کاملOntology-based information extraction and integration from heterogeneous data sources
In this paper we present the design, implementation and evaluation of SOBA, a system for ontology-based information extraction from heterogeneous data resources, including plain text, tables and image captions. SOBA is capable of processing structured information, text and image captions to extract information and integrate it into a coherent knowledge base. To establish coherence, SOBA interli...
