Development and Evaluation of Three Named Entity Recognition Systems for Serbian - The Case of Personal Names
In this paper we present a rule- and lexicon-based system for the recognition of Named Entities (NE) in Serbian news paper texts that was used to prepare a gold standard annotated with personal names. It was further used to prepare training sets for four different levels of annota tion, which were further used to train two Named Entity Recognition (NER) sys tems: Stanford and spaCy. All obtained models, together with a rule- and lexicon based system were evaluated on ...... provides different alignment scores. It is possible to compare a pair of XML files, a pair of files in BRAT for mat and one XML file against a file in BRAT for- mat. The first file is the output of a NER sys- tem and the second file represents a gold stan- dard.10 7 Future Work For the upcoming research ...

Integrative GHG Assessment in Oil and Gas Industry
Reducing greenhouse gas emissions is one of the main targets of national strategies in European countries. As a main contributor to emissions, the energy sector is recognized as the most promising to apply measures and actions aimed to decrease GHG emissions.

Towards the semantic annotation of SR-ELEXIS corpus: Insights into Multiword Expressions and Named Entities
Овај рад представља активности на развоју корпуса ELEXIS-sr, српском додатку вишејезичном анотираном корпусу ELEXIS-а, који се састоји од семантичких анотација и репозиторија значења речи. ELEXIS је паралелни вишејезични анотирани корпус на десет европских језика, који може да се користи као вишејезички репер за евалуацију европских језика са мање и средње развијеним ресурсима. Фокус овог рада је на вишечланим изразима и именованим ентитетима, њиховом препознавању у скупу реченица ELEXIS-sr и поређењу са анотацијама на другим језицима.

Adsorption and Polymerization of Aniline on Cu(II)-Montmorillonite: Vibrational Spectroscopy and ab Initio Calculation
Batch adsorption experiments in the presence of oxygen were performed to study the interlayer reactions of aniline on Cu(II)-montmorillonite in aqueous solutions. At concentrations below a critical value of CC ) 2.6 mmol dm-3 only a colored Cu(II)-aniline complex is formed, characterized by a stability constant of log(Kassoc/dm3 mol-1) ) 1.5. At concentrations beyond Cc aniline polymerizes yielding a dark brown product, which is identified by two vibrational spectroscopy techniques, attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy and ...M.

Oдређивање броја камиона за транспорт руде на површинском копу Шупља стијена
Грујичић Стефан (2024)Транспорт на површинским коповима се одвија паралелнпо са осталим процесима екаплоатације. Како не би долазило до непредвиђениих трошкова, потребно је усагласити све системе производње. Димензионисање адекватног транспортног система обезбеђује максималну продуктивност механизације и профитабилну експлоатацију. Чињеница да трошкови транспорта заузимају знатан део укупних трошкова иде у прилог томе да је одређивање потребног броја камиона за превоз откопаног материјала од великог значаја.

Application of Expansive Mortars for the Formation of Artificial Screens During Blasting in Urban Areas
During construction of buildings in urban areas, sometimes there is a need to blast solid rock mass in the immediate vicinity of the surrounding buildings. In that case, the aim is not only to increase the efficiency of blasting, but also to reduce harmful effects of ground vibration induced by blasting.
