Abstract
Purpose
This paper aims to develop a system, which would enable efficient management and exploitation of documentation in electronic form, related to mining projects, with information retrieval and information extraction (IE) features, using various language resources and natural language processing.
Design/methodology/approach
The system is designed to integrate textual, lexical, semantic and terminological resources, enabling advanced document search and extraction of information. These resources are integrated with a set of Web services and applications, for different user profiles and use-cases.
Findings
The use of the system is illustrated by examples demonstrating keyword search supported by Web query expansion services, search based on regular expressions, corpus search based on local grammars, followed by extraction of information based on this search and finally, search with lexical masks using domain and semantic markers.
Originality/value
The presented system is the first software solution for implementation of human language technology in management of documentation from the mining engineering domain, but it is also applicable to other engineering and non-engineering domains. The system is independent of the type of alphabet (Cyrillic and Latin), which makes it applicable to other languages of the Balkan region related to Serbian, and its support for morphological dictionaries can be applied in most morphologically complex languages, such as Slavic languages. Significant search improvements and the efficiency of IE are based on semantic networks and terminology dictionaries, with the support of local grammars.

The purpose of this paper is to investigate the microbial profile of food contact surfaces (FCS) in foodservice industry of Serbia.
Abstract
Purpose
The purpose of this paper is to investigate the microbial profile of food contact surfaces (FCS) in foodservice industry of Serbia.
Design/methodology/approach
The research covered 21,485 samples collected from 1,085 foodservice establishments during a period of 43 months. Results were deployed in terms of food contact materials, types of FCS and types of foodservice establishments.
Findings
Highest share of results=2 log10 CFU/cm2 were present on plastic surfaces during Autumn, while on ceramic and stainless steel surfaces highest share were observed during the Summer season. Take-away food establishments had the highest share of results=2 log10 CFU/cm2 for both stainless steel and plastic surfaces. Highest share of stainless steel surfaces with microbial load=2 log10 CFU/cm2 were cutlery, dishes and knives. Plastic dishes had the highest share of results=2 log10 CFU/cm2 while cutting boards had the majority of results between 1 log10 CFU/cm2 and 2 log10 CFU/cm2.
Research limitations/implications
Limitations of the research stem from the discussion of the nature of the FCS like porosity and other physical characteristics.
Practical implications
This research has a practical application in terms of establishing process hygiene levels depending on types of food contact materials and types of FCS and seasonal variations.
Originality/value
The findings of this study are worthy, in respect to possible correlation between seasonal variation and process hygiene requirements and can facilitate a better understanding of microbial risks associated with food preparation.
