Indexing of textual databases based on lexical resources: A case study for Serbian
In this paper we describe an approach to improvement of information retrieval results for large textual databases by pre-indexing documents using bag-of-words and Named Entity Recognition. The approach was applied on a database of geological projects financed by the Republic of Serbia in the last half century. Each document within this database is described by metadata, consisting of several fields such as title, domain, keywords, abstract, geographical location and the like. A bag of words was produced from these ...... represented by respective queries. For ex- ample, the first informational need “gold in Bor and the surrounding area” is converted into formal Boolean query (zlato OR Au) AND (Bor OR Borski okrug) ‘(gold OR Au) AND (Bor OR Bor district)’. For evaluation standard measures were used, namely Precision P = tp/(tp+ ...

... two words. If another criterion is added, for example location, then keywords which define the desired location are entered, e.g. Bor (the name of a city) or Borski okrug ‘Bor county’.

Uporedna analiza stabilnosti završnih kosina površinskog kopa „Veliki Krivelj“
Mihajlo Topalović (2023)Površinski kop „Veliki Krivelj“ nalazi se u blizina grada Bora i u neposrednoj blizini sela Krivelj. Od 2018. godine je u vlasništvu kineske kompanije „Zijin“ koja ima udeo od 63% vlasništva celokupnog RTB-a Bor. Na površinskom kopu obavlja se masovna eksploatacija rude bakra opremom visokog kapaciteta. Za bušenje se koriste bušilice prečnika od 250 do 310 mm, a za utovar minirane rude i jalovine bageri čija je zapremina kašike 15 m3 i 22 m3. Za površinski kop „Veliki Krivelj“ ...Mihajlo Topalović.
