Rule-based Automatic Multi-word Term Extraction and Lemmatization
In this paper we present a rule-based method for multi-word term extraction that relies on extensive lexical resources in the form of electronic dictionaries and finite-state transducers for modelling various syntactic structures of multi-word terms. The same technology is used for lemmatization of extracted multi-word terms, which is unavoidable for highly inflected languages in order to pass extracted data to evaluators and subsequently to terminological e-dictionaries and databases. The approach is illustrated on a corpus of Serbian texts from ...... using Unitex, a corpus processing system (http://www-igm.univ-mlv.fr/~unitex), and LeXimir, a multipurpose software tool for language resources management, developed within the University of Belgrade HLT group (Stanković et al. 2011). The whole process is automated, and takes place with very little ...

Hidrohemijske karakteristike termomineralnih voda Mataruške Banje
Snežana Kretić, Jana Štrbački (2022)Mataruška Banja je naseljeno mesto u Centralnoj Srbiji, koje teritorijalno pripada opštini Kraljevo. Banja je poznata po prirodnim lekovitim vodama visokih temperatura. Formiranje termomineralnih voda vezuje se za rasprostranjenje magmatskih stena. Cilj rada je definisanje hidrohemijskog sastava ovih voda i razmatran je kroz rezultate osam kompletnih hemijskih analiza i jedne skraćene hemijske analize, uzete sa bunara MB-2/81. Hidrogeološka istraživanja, uzorkovanje i izrada kompletnih hemijskih analiza izvršeni su u periodu od 1981. do 2004. godine, dok je uzorkovanje i izrada ...Mataruška Banja, termomineralne vode, kvalitet podzemnih voda, vodonik-sulfid, metasilicijumska kiselinaSnežana Kretić, Jana Štrbački .

Upper Miocene depositional environments of the Kikinda-Mokrin High (Serbia)
Saša Ivanišević, Dejan Radivojević (2018)Exploration for oil and gas in mature areas, such as the Pannonian Basin, can benefit from reexamination of old data using more advanced modern workflows that focus on the temporal and spatial aspects of sediment deposition. Specifically, we apply a new environment of deposition model that interprets the Upper Miocene- Pliocene sediments as being deposited in a rapidly filling basin characterized by quick shelf edge progradation from the northwest toward the southeast. Reconstruction of this shelf edge trajectory reveals ...Saša Ivanišević, Dejan Radivojević.

Određivanje zbijenosti starog komunalnog otpada
Bez obzira na savremene tretmane komunalnog otpada u svetu, u Srbiji je i dalje najčešći vid odlaganja na komunalne deponije, pa zbijanje otpada predstavlja jednu od ključnih faza formiranja deponije. Na ovaj način znatno se smanjuje zapremina otpada, ubrzava proces degradacije i produžava radni vek deponije. Zbog toga su geotehničke karakteristike komunalnog otpada prilikom zbijanja, veoma bitne kako u fazi projektovanja tako i u fazi izgradnje deponije i optimizacije prostora. Tu se pre svega misli na maksimalnu suvu zapreminsku ...Jovana Janković, Dragoslav Rakić, Irena Basarić Ikodinović, Tina Đurić.

Coupling of artificial intelligence methods in the development of hybrid intelligent systems
In this paper we present an approach which couples various artificial intelligence (AI) methods in the solution of complex problems that cannot adequately be solved by a single AI method.

Different coupling methods are analyzed and a classification of hybrid systems based on the chosen method is given.

An Approach to Efficient Processing of Multi-Word Units
Efficient processing of Multi-Word Units in the course of development of morphological MWU dictionaries is not easy to achieve, especially when languages with complex morphological structures are concerned, such as Serbian. Manual development of this type of dictionaries is a tedious and extremely slow process.
