LINDASearch: a faceted search system for linked open datasets

Abstract

The importance of Linked Data lies on the fact that its practices and principles have been adopted by an increasing number of data providers, resulting in the creation of a data space on the Web containing billions of RDF Triples and accessible worldwide throughout the Internet. RDF datasets can be queried by tools and applications for searching and gathering information. However and due to the huge amount and types of dataset, the selection and reuse of data resources is not easy task. Therefore, a metasearch system for open Linked Data projects called LINDASearch (LINDASearch stands for Linked Data Search) is introduced. LINDASearch provides a middleware architecture in order to provide information about the most known Open Linked Data Projects such as DBpedia, The GeoNames geographical database, LinkedGeoData, FOAF profiles, Global Health Observatory, Linked Movie DataBase (LinkedMDB) and World Bank Linked Data. This paper describes the LINDASearch's architecture as well as its functionality through one case study divided in two scenarios in order to show the architecture's functionality and present the results obtained from each scenario.
