VISUALIZATION OF COMPLEX DATA IN PROCESSING ENVIRONMENT

Uporabnost kompleksnih podatkov, med katerimi so zelo pomembne ontologije, je v veliki meri odvisna od njihove ustrezne vizualizacije. Vizualizacija kompleksnih podatkov ni trivialno opravilo in zahteva dobro premišljen koncept ter implementacijo z ustreznim orodjem, ki po možnosti omogoča tudi objavo na svetovnem spletu. Eno takih orodij naj bi bilo tudi Processing, zato ga bomo v diplomi podrobno spoznali. Processing omogoča razvijanje grafično bogatih aplikacij. Temelji sicer na platformi Java, vendar vpeljuje svoj inovativen način razvoja grafičnega uporabniškega vmesnika. Ogledali si bomo tudi sestrski projekt okolja Processing, imenovan Processing.JS, ki omogoča prenos Processing aplikacij na splet z možnostjo izvajanja kot popolne HTML5 spletne aplikacije. Ker se bomo lotili vizualizacije ontologij, bomo pregledali še koncepte semantičnega spleta in preučili standarde, ki semantični splet omogočajo. S pomočjo pridobljenih znanj se bomo nato osredotočili na razvoj Processing aplikacije, ki bo iz izbrane ontologije razbrala pomembne podatke in jih grafično prikazala ter tako omogočila uporabniku njihovo lažje interpretiranje.Usefulness of complex data, of which ontologies present a very important role, depends a great deal on their adequate visualization. Vizualization of complex data is not a trivial task. It demands a well-thought-out concept and should be implemented using an appropriate tool, which should possibly allow developer to publish it on the world wide web. One of such tools is Processing environment, and that\u27s why we will get to know it in detail. Processing is used for rich application development. It is based on Java platform, but introduces its own innovative and unique application user interface development methods. We\u27ll take a look at Processing\u27s sister project named Processing.JS, which enables Processing applications to be ported to the web. Processing.JS applications run as fully compatible modern HTML5 web applications. As we want to visualize ontologies, in the second half of this diploma we\u27ll look through semantic web concepts and study standards which enable semantic web. With knowledge gained we\u27ll focus on developing Processing application, which will read through selected ontology and collect meaningful data from it. After that, our application will present collected data graphically and thus allow easier interpretation of given data
