On the compatibility of lexical resources for NooJ
Lexical resources for many languages are provided for the NooJ linguistic development environment. Meta-data descriptions of morphosyntactic and semantic properties of these languages and their resources are a mandatory part of each language module. In this paper we analyze how well the meta-data actually describe resources for a chosen subset of languages and to what extent are they compatible across languages to support multilingual processing. We show that there is place for improvement in both directions.... more numbers connected by a comma or a conjunction (or ), invoke their specific „measure“ sub- graphs which recognize different measure units, either as character strings: kilometer, meter, foot, feet, pond, mile, or as patterns , .

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 ...... of lexicographic leaflets is described in Stijović (2018). Out of 19 volumes, two were available as MS Word files, two as PDF files, and the others only in paper form. Unfortunately, neither MS Word nor PDF files could be used without further preprocessing, since non-Unicode character sets were used ...

Medical Domain Document Classification via Extraction of Taxonomy Concepts from MeSH Ontology
Mihailo Škorić, Mauro Dragoni (2019)This paper is a result of a task that was presented to attendants of Keyword Search in Big Linked Data summer school, that was organized by Vienna University of Technology, under the Keystone COST action in the summer of 2017. It presents a specific approach to the classification via creation of minimal document surrogates based on the US National medical library’s MeSH ontology, which is derived from the Medical Subject Headings thesaurus. In a series of previously classified medically ...... concept names are located in the documents and replaced with the node identifiers from the taxonomic tree.

The state and perspective of the natural gas sector in Serbia
The strategy of long-term energy development of Serbia identifies an increase of share of natural gas in final energy consumption as one of the main aims.

Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs
John Nyame (2024)The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ...... parallel units were needed.

Improving Document Retrieval in Large Domain Specific Textual Databases Using Lexical Resources
Large collections of textual documents represent an example of big data that requires the solution of three basic problems: the representation of documents, the representation of information needs and the matching of the two representations. This paper outlines the introduction of document indexing as a possible solution to document representation. Documents within a large textual database developed for geological projects in the Republic of Serbia for many years were indexed using methods developed within digital humanities: bag-of-words and named ...... for searching the textual databases in GeolISS (which is in use for several years) is based on user queries consisting of keywords, single or multi-word units (MWU), which can be combined into Boolean expressions.

During the highpressure and high-temperature synthesis (HPS) process at 4 GPa and 1,200 °C, sphene undergoes into phase transition, from room-temperature phase P21/a to high-temperature phase A2/a. Evidence of that structural phase transition is given in this paper using infrared, Raman spectroscopy and X-ray powder diffraction.
