<p>U stvarnom životu većina informacija dolazi kao neprecizne ili<br />nepotpune vrednosti.&nbsp; XML tehnologija je napravila veliki<br />napredak u oblasti skladi&scaron;tenja i prenosa podataka.&nbsp; Doktorska<br />disertacija defini&scaron;e fazi XML sintaksu koja kombinuje neodređenosti<br />u vrednostima XML-a i neodređenosti u strukturi XML dokumenata.<br />Takođe, rad pro&scaron;iruje standardnu XQuery upitnu sintaksu fazi<br />elementima i uvodi prioritete i pragove zadovoljenja pomoću<br />GPFCSP-a. Za razliku od drugih radova koji se fokusiraju na<br />postavljanje teorija i definisanje sintaksi, rad posebnu pažnju<br />posvećuje praktičnoj upotrebi definisanih sintaksi. Za potrebe<br />istraživanja razvijen je softverski paket koji omogućava rad kako sa<br />standardnim, tako i sa fazi XML, XSD i DTD dokumentima, kao i<br />postavljanje i izvr&scaron;avanje prioritizovanih fazi XQuery upita. Alat je<br />testiran nad primerima iz prakse.</p> / <p>In real life, as opposed to virtual, most information comes in the<br />form of imprecise or incomplete values. XML&nbsp; technology has<br />made great progress in the field of storage and data transfer.<br />This doctoral dissertation&nbsp; developed XML extension which<br />combines&nbsp; indefiniteness in the values of XML and<br />indefiniteness in the structure of XML into a single fuzzy XML<br />extension. Furthermore,&nbsp; dissertation&nbsp; expands XQuery syntax<br />with fuzzy values and&nbsp; includes priorities and thresholds in<br />fuzzy XQuery extension using&nbsp; GPFCSP for the first time.<br />Unlike other papers that focus on setting up theories and<br />defining syntax, in this&nbsp; dissertation, special attention&nbsp; is turned<br />to their practical use. A tool for working with XML, XSD and<br />DTD documents and prioritized fuzzy XQuery extension<br />queries has been developed. The tool has been tested on<br />practical examples.</p>
