Advancing Sentiment Analysis in Serbian Literature: A Zero and Few-Shot Learning Approach Using the Mistral Model
Ova studija predstavlja analizu sentimenta srpskih starih romana iz perioda 1840-1920, koristeći veliki jezički model (LLM) Mistral za tehniku učenja sa zasnovani na takozvanim "zero" i "few-shot" pokušajima. Glavni pristup uvodi inovacije osmišljavanjem istraživačkih upita (promptova) uključuju tekst sa uputstvom za klasifikaciju bez primera i na osnovu nekoliko primera, omogućavajući jezičkom modelu da klasifikuje osećanja u pozitivne, negativne ili objektivne kategorije. Ova metodologija ima za cilj da pojednostavi analizu osećanja ograničavanjem odgovora, čime se povećava preciznost ...Milica Ikonić Nešić, Saša Petalinkar, Mihailo Škorić, Ranka Stanković, Biljana Rujević.

Geochemistry of neutral mine drainage at sulfide deposits ‒ example of the „Grot“ Pb-Zn mine, South-Eastern Serbia
U ovom radu proučavan je hemijski sastav voda iz rudnika i izdvojeni su hidro-geohemijski faktori koji utiču na njegovo formiranje. Sakupljeno je 11 uzoraka vode sa 6 lokacija na području Krive Feje, kako bi se utvrdio njihov hemijski sastav. Analizom podataka utvrđeno je da su vode sa ovog područja visokog kvaliteta, HCO3--SO42--Ca2+ i SO42--Ca2+ tipa, sa neutralnom pH vrednošću. Koncentracije metala u ovim vodama (cinka, olova, barijuma, bakra i hroma) generalno su niske i većina uzoraka voda ispunjava kriterijume ...podzemne vode, kisele rudničke vode, hidrogeohemijski faktori, metali, PHREEQC modeliranje, indeks saturacijeSnežana Kretić, Jana Štrbački, Nebojša Atanacković.

E-Connecting Balkan Languages
In this paper we present a versatile language processing tool that can be successfully used for many Balkan languages. This tool relies for its work on several sophisticated textual and lexical resources that were developed for most of Balkan languages. These resources are based on several de facto standards in natural language processing.Cvetana Krstev, Ranka Stanković, Duško Vitas, Svetla Koeva.

Fuzzy expert analysis of the severity of mining machinery failure
Mining machinery failure is almost an everyday occurrence. Usually the failures bare certain consequences, which require additional financial costs to repair and restore the system to its operational state. The consequences are viewed through negative and damaging effects a failure has on the machine, health and safety of the employees, work environment, and on the environment. The removal of the consequences of the failure requires additional financial investment, which has a negative impact on the company’s business. In order ...... indicators’ values (S, O, and D). Even though one of the indicators can be ranked very high and the other two at a low level (9, 3, and 2), the value of RPN will be lower than when all indicators are ranked in the category moderate (4, 5, and 4).

The Usage of Various Lexical Resources and Tools to Improve the Performance of Web Search Engines
In this paper we present how resources and tools developed within the Human Language Technology Group at the University of Belgrade can be used for tuning queries before submitting them to a web search engine. We argue that the selection of words chosen for a query, which are of paramount importance for the quality of results obtained by the query, can be substantially improved by using various lexical resources, such as morphological dictionaries and wordnets. These dictionaries enable semantic ...LR web services, MultiWord Expressions & Collocations, Information Extraction, Information RetrievalKrstev Cvetana, Stanković Ranka, Vitas Duško, Obradović Ivan.

Influence of DEM resolution on numerical modelling of debris flows in RAMMS - Selanac case study
Debris flows induced by intensive rainfall represent very hazardous phenomena in many parts of the World. Methods for prediction of runout distance of flow like mass movements are different and depending on the input data, rheology, and available or appropriate numerical solution. However, sometimes it is not easy to obtain pre event and post event high-resolution data in the rural or mountainous area. Thus, the topology of terrain is the most important input parameter for the every real case ...Jelka Krušić, Biljana Abolmasov, Mileva Samardžić Petrović.
