In recent years, with the fast development of computer and Internet technologies, text-mining computer methods are becoming more and more important. Computer systems capacities can be further used in ...such areas as text summarization, information retrieval, text correcting, determining text subject, machine text translation, creating lexicons, determining text sentiment. This monograph is focused on sentiment analysis in the most popular meaning of this phrase i.e. on the sentiment of the whole document. The problems of binary classification (two document groups), staying away from external sources, using the training set but in the possibly smallest size, were emphasized. The monograph’s targets are: providing a comparative review of sentiment analysis methods to be found in literature, investigating the quality of selected methods of document sentiment classification in applications to Polish language written documents, proposing new methods which would upgrade the classification quality or possess other advantages. An original method with simple interpretation has been proposed which proved to be better than standard methods applied to classify English language documents, especially in the case of documents corpora with similar number of documents in both classes. The research was carried out on thirteen sets of documents from different independent sources.
The purpose of the article/hypothesis: In recent years, there has been a noticeable and dynamic development of micromobile equipment intended for the transport of people. These types of vehicles are ...known as personal transport equipment (PTE). Like any road vehicle, PTE can also cause numerous accidents and collisions. A natural consequence of damage related to the use of PTE is posing the question about securing the interests of the aggrieved parties. Considering the above, the aim of this paper is to present the role of civil liability insurance for users of personal transport equipment in the context of claims related to the use of this type of vehicles and to provide a brief description of insurance products available on the market. The paper presents the following thesis: although the regulations do not oblige PTE users to have a civil liability insurance policy, a wide catalogue of adverse events related to the PTE use requires the popularisation of insurance protection for users of this type of vehicles. Such insurance protection should cover: equipment users, renters, sellers, and operators, as well as households. Methodology: The paper is theoretical and analytical in its nature. In addition to the review of the available literature, the existing offer of voluntary insurance for PTE users is also analysed. Results of the research: Insurance addressed to users of personal transport equipment is a relatively new product on the market and still few insurance companies have it in their offer. PTE users can utilise their civil liability insurance often being part of their home insurance in their private life, which offers protection in the event of damage to third parties. One of the solutions leading to the dissemination of insurance protection could be a proposal of insurance tailored to the type of risk and short-term use associated with this kind of equipment (e.g. travel-type insurance).

The weighted average cost of capital is the rate that companies must pay to shareholders and creditors. Therefore, it is a risk-adjusted discount rate for the company‘s cash flows. The paper will ...calculate the weighted average cost of capital for a selected group of companies listed on the Sarajevo and Banja Luka Stock Exchanges, as well as profitability indicators such as: ROA, ROE and net profit margin.

The research results show that the WACCranges from a minimum of 5.11% to a maximum of 10.87%. Likewise, the research results show that there is a negative connection and correlation between WACC on the one hand and a selected group of profitability indicators on the other hand.
