THE USE OF LINKED DATA APPROACH FOR THE INTEGRATION OF DISTRIBUTED WEB DATA

Diplomsko delo predstavlja koncept Linked Data. To je skupek smernic in tehnologij za objavo podatkov na spletu in povezovanje podatkov med različnimi podatkovnimi viri tako, da bodo ti razumljivi tako ljudem kot računalnikom. Smernice za objavo podatkov smo podrobneje predstavili in jih razložili. Predstavili smo tudi semantične tehnologije za dostop do takih podatkovte so RDF, SPARQL in MQL. V praktičnem delu diplomske naloge smo implementirali aplikacijo, ki uporablja podatke iz različnih virov. Ti podatki so povezani po načelih Linked Data. Podatke smo pridobivali iz Dbpedije in Freebase semantične podatkovne baze in semantične storitve Flickrwraper. Aplikacija omogoča prikaz turističnih informacij o mestih in njihovih turističnih znamenitostih. Predstavili smo tudi težave, na katere smo naleteli med razvojem opisane Linked Data aplikacije.The thesis presents Linked Data concept. This is a collection of guidelines and technologies for publishing data on the web and interlinking of data between different data sources in such a way that the published data can be used by humans and computers. These guidelines for data integration were presented and explained in detail. We also presented some important semantic web technologies such as RDF, SPARQL and MQL. In the practical part of the thesis we developed an application that uses interlinked data from different sources. The data was interlinked based on the Linked Data principles. Our application acquired data from Dbpedia and Freebase semantic databases and a semantic service called Flickrwraper. The implemented application is a mashup that presents tourist information about cities and tourist attractions. Problems that we encountered during development of our Linked Data application were also presented
