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. This approach ...... published. For the de- velopment of the lexical database model for the DSA, a similar approach was used as in Stanković et al. (2018) for the Serbian morphological electronic dictionary. The main class, in the core of this dic- tionary model, is LexicalEntry, representing a headword of the dictionary ...

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 ...... (DNNs) (Huang et al., 2015; Choi, 2016; Akbik et al., 2018). The first operational tagger and lemmatization model for Serbian were produced as a parameter file (TT11) for the TreeTagger model (Schmid, 1999) after a thorough anal- ysis of the state-of-the-art solutions (Popović, 2010), and subsequently ...

Početak njihove aktivnosti vezuje se za rotaciju tektonskih jedinica Karpato-balkanida (Dacia Mega Unit) oko rigidne Mezijske jedinice. Aktivnost ovih transkurentnih raseda je akomodirala ovu rotaciju, pa se smatra da je kumulativno kretanje duž Timočkog raseda tokom perioda njegove aktivnosti bilo do 100 km.

The impact of limestone fragmentation on raw mix production in cement industry
Raw mix design is one of crucial point in production of clinker. Cement industry use limestone, marl, clay in particular percent to provide the best quality in production of clinker.

Blasting is an operation which affects all subsequent operations and costs. The Kuz-Ram model is possibly the most widely used approach to ...Nikola Đokić, Lazar Kričak, Stefan Milanović, Marinko Pavlović, Stefan Krstić.
