Using Lexical Resources for Irony and Sarcasm Classification
The paper presents a language dependent model for classification of statements into ironic and non-ironic. The model uses various language resources: morphological dictionaries, sentiment lexicon, lexicon of markers and a WordNet based ontology. This approach uses various features: antonymous pairs obtained using the reasoning rules over the Serbian WordNet ontology (R), antonymous pairs in which one member has positive sentiment polarity (PPR), polarity of positive sentiment words (PSP), ordered sequence of sentiment tags (OSA), Part-of-Speech tags of words (POS) ...... da bo odločitve partije zje*** neko Ustavno Sodišče?

Using English Baits to Catch Serbian Multi-Word Terminology
In this paper we present the first results in bilingual terminology extraction. The hypothesis of our approach is that if for a source language domain terminology exists as well as a domain aligned corpus for a source and a target language, then it is possible to extract the terminology for a target language. Our approach relies on several resources and tools: aligned domain texts, domain terminology for a source language, a terminology extractor for a target language, and a ...aligned texts, word alignment, terminology extraction, electronic dictionaries, morphological inflection... ac ij a ni je bi bl io te čk ia so ci ja ci ja bi bl io te čk ia so ci ja ci ja bi bl io te ka dr uš tv o as so ci at io n li br ar y 1, 3, 5, 6 ye s ud ru že nj a ia so ci ja ci ja po pu tb ib li ot ek e ud ru že nj e ia so ci ja ci ja po pu tb ib li ot ek ...

Quantitative landslide risk assessment in the city of Tuzla

The urbanization is expansive and more aggressive than before, but so are the weather extremes and long-term climate trends.

Pleistocene rhinoceros from Bogovina Cave: the first report of Stephanorhinus hundsheimensis Toula, 1902 (Mammalia, Rhinocerotidae) from Serbia
Finds of Pleistocene rhinoceros are rare in Serbia, and only one species (the woolly rhinoceros Coelodonta antiquitatis Blumenbach, 1799) has been reported so far.
