Испитивање могућности флотирања церузитне руде из лежишта Олово - БиХ
Славко Тодић (2024)Овај завршни рад заснива се на испитивању могућности флотирања церузитне руде из лежишта Олово - БиХ. У циљу свеобухватног испитивања и добијања што прецизнијих резултата, у општем делу рада представљени су географски положај и историјат, како рудника, тако и општине Олово, затим геолошка грађа подручја, минерални састав лежишта и његове структурно-текстурне карактеристике. Такође, у овом делу рада дат је и кратак увид у минералошку анализу руде из лежишта Олово, те опште карактеристике корисних минерала церузита/англезита и калцита као основне некорисне ......

Machine Learning and Deep Neural Network-Based Lemmatization and Morphosyntactic Tagging for Serbian
The training of new tagger models for Serbian is primarily motivated by the enhancement of the existing tagset with the grammatical category of a gender. The harmonization of resources that were manually annotated within different projects over a long period of time was an important task, enabled by the development of tools that support partial automation. The supporting tools take into account different taggers and tagsets. This paper focuses on TreeTagger and spaCy taggers, and the annotation schema alignment ......

Serbian NER&Beyond: The Archaic and the Modern Intertwinned
U ovom radu predstavljamo srpski književni korpus koji se razvija pod okriljem COST Akcije „Distant Reading for European Literary History” CA16204. Koristeći ovaj korpus romana napisanih pre više od jednog veka, razvili smo i učinili javno dostupnim Sistem za prepoznavanje imenovanih entiteta (NER) obučen da prepozna 7 različitih tipova imenovanih entiteta, sa konvolucionom neuronskom mrežom (CNN), koja ima F1 rezultat od ≈91% na test skupu podataka. Ovaj model je dalje ocenjen na posebnom skupu podataka za evaluaciju.

The Dictionary of the Serbian Academy: from the Text to the Lexical Database
In this paper we discuss the project of digitization of the Dictionary of the Serbo-Croatian Standard and Vernacular Language. Scanning and character recognition were a particular challenge, since various non-standard character set encoding was used in the course of the almost 60-year long production of the dictionary. The first aim of the project was to formalize the micro-structure of the dictionary articles in order to parse the digitized text of and transform it into structured data stored in relational lexical database.

Милан Павличић (2024)У раду су приказани резултати истражних радова који су спроведени у периоду од 13.04.2018. до 31.05.2019, у циљу дефинисање режима и категоризације резерви подземних вода на изворишту за водоснабдевање Друговца у Смедереву. Бунарима ИЕБДР-1/93 и ИЕБД-1/2002 су каптирани песковити седименати неогене старости. У току режимских осматрања вршени су тестови црпења, осматрања нивоа подземних вода, режимa падавина као и квалитетa подземних вода. Утврђене су укупне резерве подземних вода у количини од 5,3 l/s. Хемијске анализе воде показују да је хидрохемијски ...... — _— – « A — U U ım I, 20 17 – ”– —A C –— :a oj –u u —w v u u 20 19 — –: I J o o z g j r U o a u r a a y uu u I, _= am m O ~O — = a —+—.+wrn .
