Abstract
The introduction of semantic web and Linked Data helps facilitate sharing of data on the Internet more easily. Subsequently, the resource description framework (RDF) is the standard in publishing structured data resources on the Internet and is used in interconnecting with other data resources. To remedy the data integration issues of the traditional web mashups, the semantic web technology uses the Linked Data based on RDF data model as the unified data model for combining, aggregating, and transforming data from heterogeneous data resources to build Linked Data mashups. There have been tremendous amounts of efforts of semantic web community to enable Linked Data mashups but there is still lack of a systematic survey on concepts, technologies, applications, and challenges. Therefore, in this paper, we investigate in detail semantic mashups research and application approaches in the information integration. This paper also presents a Linked Data mashup application as an illustration of the proposed approaches.
Highlights
The development of generic web applications is well understood and supported by many traditional computer scienceE domains, such as classical database applications
One of main trends in semantic web community is about publishing big datasets to the web in the format of Linked Data or raw resource description framework (RDF)
This is about representing the data in form of interconnected resources. This is reflected of W3C’s vision of the semantic web: (1) the semantic web is about common formats for integration and combination of data from diverse sources, where on the original web they mainly concentrated on the interchange of documents; (2) the semantic web is about languages for representing how components
Summary
E domains, such as classical database applications. In current web application development data integration and access are typically dealt with by fairly sophisticated abstractions and tools which support rapid application development. This is about representing the data in form of interconnected resources. E the semantic web technology uses the Linked Data based on RDF data model as the unified data model for combining, aggregating, and transforming data from heterogeneous data resources to build Linked Data mashups. RThis paper investigates research and application appublishing data on the web and linking different data sources This trend has created a wave of raw data publications on the web and made it become open data sources with a highly semantic representation where individuals and organisation can share their data as an open format with each other. Described in detail as part of the W3C RDF Primer (W3C RDF Primer, http://www.w3.org/TR/rdf-primer/)
