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.

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.

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.

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 main aim of this chapter is to systematize observations regarding changes in entrepreneurship in Serbia during the previous decade, having in mind some key factors such as high-impact low-probability (HILP) events, dynamic development in the sphere of information technologies (IT), and foreign direct investments (FDI). The choice of these factors was made in accordance with the fact that there were no significant changes in other external factors in the sphere of entrepreneurship (regulatory framework, financial conditions, and socio-political instability). This chapter discusses the assumptions that HILP events and FDI can have both positive and negative impacts on individual sectors or agglomerations of entrepreneurship, while only positive impacts are attributed to IT development. Using official databases and annual financial and business reports given by entrepreneurial agencies and micro and small enterprises we created a set of reports that indicate the strength and direction of the influence of the mentioned factors and their consequences in the sphere of entrepreneurship at the level of Serbia and selected cities, based on the fact that the entrepreneurial ecosystem in those cities faced greater than average challenges. The selected ratios indicate changes in the growth rate of the entrepreneurship sector (number of entrepreneurs and employees) as well as in the improvement of its competitiveness (productivity, assets, and profit per employee).

This paper aims to define and theoretically analyse the performance of modern methods investigated to speed up the recultivation process of degraded areas, and apply it into the mining basin, open pit mines, tailings and all other areas, which need environmental quality improvement.

This paper presents methods of conservation and substitution of natural resources for the purpose of faster land recultivation (reclamation) in degraded coal mine areas. Two types of methods have been developed: forest slope recultivation and agricultural recultivation of flat landfills. Indicators of positive changes include: changes in chemical properties of tailings, increase in biogenic properties and changes in biodiversity.

The research results show that the application of these methods, along with the holistic approach and adequate investment, can significantly contribute to the length of recovery process and accelerate it.

Mining basin Kostolac is used as a model test. The results can be applied on all mining basin, open pits and any degraded area.

All results and conclusions were drawn, based on the original measurements and experiments. Stake holders, wanting to manage environmental quality after exploitation in mining basin, applying those methods, can find the value of this paper.
