  • Influence of geological substrate on runoff formation, a case study: small river catchments in southeastern Serbia of similar size and with comparable pluviographic regimes

    Vesna Ristić Vakanjac, Veljko Marinović, Nikola Milovanović, Marina Čokorilo Ilić, Boris Vakanjac, Jugoslav Nikolić, Saša Bakrač (2022)
    We are witnessing climate change that is happening both, globally and, at the regionally - or local level. As a result of expected climate change in Southeast Europe, in the first place are the distributions of precipitation within the year (frequent extreme events are present) and then the increase in temperature, which already has a significant impact on evapotranspiration and runoff formed in a particular catchment area. In addition to climatic factors, the geological structure, i.e. the hydrogeological characteristics ...

  • Named Entity Recognition for Distant Reading in ELTeC

    Francesca Frontini, Carmen Brando, Joanna Byszuk, Ioana Galleron, Diana Santos, Ranka Stanković (2020)
    Akcija COST „Udaljeno čitanje za evropsku književnu istoriju“, koja je počela 2017. godine, ima među svojim glavnim ciljevima stvaranje višejezične zbirke evropskih književnih tekstova (ELTeC) otvorenog koda. U ovom radu predstavljamo rad koji je obavljen na ručnom označavanju selekcije ELTeC kolekcije za imenovane entitete, kao i na proceni postojećih alata za prepoznavanje imenovanih entiteta u pogledu njihove sposobnosti da automatski urade takve anotacije. U poslednjem paragrafu se razmatraju zajedničke tačke između ove inicijative i CLARIN-a.

  • A Knowledge-Based Approach to Mine Ventilation Planning in Yugoslav Mining Practice

    Nikola Lilić, Ivan Obradović, Ranka Stanković (2002)
    Ventilation system analysis is a complex process based on the calculation and analysis of numerous parameters. These problems can be successfully solved by the SimVent numerical package, but a full understanding and use of the obtained results require the involvement of an experienced specialist in the ventilation field. The solution was found in the creation of a hybrid system INVENTS, whose knowledge base represents a formalization of the expert knowledge in the mine ventilation field. In this paper, we ...
