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.

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.

Geotehnički uslovi izgradnje metro stanice „Savski trg“ – beogradski metro linija 1
Ukrštanje linija 1 i 2 beogradskog metroa, planirano je na lokaciji “Savski trg” gde će se izgraditi zajednička metro stanica. Zbog složene konstrukcije objekta i različite dubine dijafragmi, koja na delu metro linije 2 iznosi preko 40 m, planirana je fazna izgradnja. U vezi sa tim u radu je prikazan način definisanja geotehničkog modela, kao i geotehnički proračuni u kojima su analizirani: fazni načini iskopa, filtraciona analiza, uticaj pornih i efektivnih napona na stabilnost dijafragme, horizontalna i vertikalna ...beogradski metro, metro stanica, geotehnički model, stabilnost dijafragme, horizontalna pomeranja, vertikalna pomeranjaDragoslav Rakić, Nemanja Stanić, Josip Išek, Slavoljub Stojković.

Selection of Artificial Lift Methods: A Brief Review and New Model Based on Fuzzy Logic
Miroslav Crnogorac, Miloš Tanasijević, Dušan Danilović, Vesna Karović Maričić, Branko Leković (2020)Artificial lift methods have applications in oil wells where oil production is no longer possible due to natural reservoir energy, so this necessary energy is added by introducing lift methods. In order to achieve optimum production, the selection of an artificial lift method is very important. This paper uses fuzzy logic as a mathematical and conceptual model for selection of the optimal artificial lift method. The outcome or IF-THEN rules, as the central part of the model, is based ...... can be written as: low = (0/1, 0/2, 1/3, 1/4, 0.33/5, 0/6, 0/7, 0/8, 0/9, 0/10) moderate = (0/1, 0/2, 0/3, 0.5/4, 1/5, 1/6, 0.5/7, 0/8, 0/9, 0/10) high = (0/1, 0/2, 0/3, 0/4, 0/5, 0.33/6, 1/7, 1/8, 0/9, 0/10) very high = (0/1, 0/2, 0/3, 0/4, 0/5, 0/6, 0/7, 0/8, 1/9, 1/10) Input parameters can be ...
