Usage analysis of system for theses acquisition and plagiarism detection

AbstractThe national project of The Central Register of the Theses has started in 2008. The project serves as an integrating system for acquisition, archiving and plagiarism detection of the theses from academic information systems of Slovak universities. The first phase of its development has been devoted to the tasks accompanying the processes of acquisition and archiving electronic versions of theses. The national character of the project requires unification of processes associated with theses writing, plagiarism detection and acquisition final versions of the theses from different universities in Slovak republic. The universities, like primary users of this system, have had to adapt their own processes associated with writing, acquisition and archiving of electronic versions of the theses. These inevitable changes have naturally raised many students’ and academic staff’s questions at universities. The same situation has happened at the Constantine the Philosopher University in Nitra and has led to the development of the helpdesk designed for all stakeholders. The helpdesk has provided relevant and digestedly prepared tutorials and discussion forum about abovementioned changes. The activities of the users have been monitored for the purpose of their further processing and identification of the weaknesses of the theses writing, plagiarism detection and acquisition at the university level. The usage analysis of the presented helpdesk and the segmentation method of its users are discussed in detail in the paper. The segmentation method is based on the monitoring of the users’ activities in discussion forums, their searching techniques in available information sources and in posting questions about theses finalization, acquisition and archiving. The authors analyse some aspects of their behavior and discuss interesting findings of the usage analysis of the helpdesk. They give several recommendations for changes in the stakeholder awareness and in the structure of published information materials

Impact of different pre-processing tasks on effective identification of users’ behavioral patterns in web-based educational system

Abstract Analyzing the unique types of data that come from educational systems can help find the most effective structure of the elearning courses, optimize the learning content, recommend the most suitable learning path based on student's behavior, or provide more personalized environment. We focus only on the processes involved in the data preparation stage of web usage mining. Our objective is to specify the inevitable steps that are required for obtaining valid data from the stored logs of the webbased educational system. We compare three datasets of different quality obtained from logs of the web-based educational system and pre-processed in different ways: data with identified users' sessions and data with the reconstructed path among course activities. We try to assess the impact of these advanced techniques of data pre-processing on the quantity and quality of the extracted rules that represent the learners' behavioral patterns in a web-based educational system. The results confirm some initial assumptions, but they also show that the path reconstruction among visited activities in e-leaning course has not statistically significant effect on quality and quantity of the extracted rules

Pillar 3 and Modelling of Stakeholders’ Behaviour at the Commercial Bank Website during the Recent Financial Crisis

AbstractThe paper analyses domestic and foreign market participants’ interests in mandatory Basel 2, Pillar 3 information disclosure of a commercial bank during the recent financial crisis. The authors try to ascertain whether the purposes of Basel 2 regulations under the Pillar 3 - Market discipline, publishing the financial and risk related information, have been fulfilled. Therefore, the paper focuses on modelling of visitors’ behaviour at the commercial bank website where information according to Basel 2 is available. The authors present a detailed analysis of the user log data stored by web servers. The analysis can help better understand the rate of use of the mandatory and optional Pillar 3 information disclosure web pages at the commercial bank website in the recent financial crisis in Slovakia. The authors used association rule analysis to identify the association among content categories of the website. The results show that there is in general a small interest of stakeholders in mandating the commercial bank's disclosure of financial information. Foreign website visitors were more concerned about information disclosure according to Pillar 3, Basel 2 regulation, and they have less interest in general information about the bank than domestic ones

The influence of some selected variables from accounting system on profit or loss of agricultural companies in the Slovak republic

The article presents the influence assessment of significance of some selected variables from the entrepreneurs' accounting system on the achieved profit or loss of the agricultural companies in the Slovak Republic. Accounting information serves as an active tool for internal users for operational as well as strategic company management, and for external users the information is determined as legally binding output information which is a subject to disclosure. Individual financial statements of assessed agricultural companies are considered to be the relevant source of information. Agricultural companies are represented by commercial companies and agricultural cooperatives. Profit or loss after income tax presents the final complex effect of economic company's performance. The existence and development of companies is conditioned by assets which amount and structure depend on focus and the range of subject activity but as well as on specific factors set by the production process in the agricultural primary production. The increase in liabilities is notable by the influence of unsufficient amount of own company funding sources, mainly the increase in trade payables. The continuance of company reproduction process is secured by a bank loan drawdown. The income situation of companies of agricultural primary production is favourably influenced by the subsidies of non-investment character. During the observed period of years 2004 - 2014 the examined variables were assessed by means of statistical methods. The obtained results of rate determination of statistical correlation between selected variables by means of classical canonical analysis and non-parametric correlation analysis secured that in the assessed group of companies all analysed variables influenced statistically significantly profit or loss after income tax, mainly the total value of assets and non-investment subsidies, except for years 2010, 2012 a 2013, when the statistically insignificant correlations was determined between profit or loss and especially short-term trade payables and current bank loans. As regards the existence point of view it is recommended to companies to maintain the optimal assets and capital structure as well as the achievement of suitable profitability of company's activity. Only the complex attitude towards the subject issue can be the assumption of sustainability for companies of agricultural primary production in the Slovak Republic and the increase in their performance
