Current Status and Plans for Further Development of Acta Informatica Pragensia

Zdenek Smutny, Stanislava Mildeova

Acta Informatica Pragensia 2022, 11(2), 149-151 | DOI: 10.18267/j.aip.1912037  

The editorial summarizes the development of the Acta Informatica Pragensia journal over the last four years (2019–2022). Thanks to the indexing of the journal in the Scopus citation database since 2019, the journal has not only consolidated its position in Central Europe but also began to build its position in the international community of informaticians. The paper presents Scopus metrics and statistics of submitted and accepted articles for the observed period of four years. Furthermore, it presents Acta Informatica Pragensia in the context of other informatics-oriented journals published in the Czech Republic and indexed in the Scopus or Web...

Comments on Copyright Aspects of Use of Copyright Works in Digital Teaching

Martin Boháček

Acta Informatica Pragensia 2022, 11(2), 152-178 | DOI: 10.18267/j.aip.1784475  

In the current COVID-19 pandemic, teachers and students routinely take part in schooling via digital technologies, using their own and other authors' copyrighted works, even without their permission or licence. The aim of this article is to identify these aspects of copyright in online teaching and to offer solutions to them. Some of these aspects are addressed by EU Directive No. 2019/790 (Digital Directive), the implementation of which was reflected in the draft amendment to the Czech Copyright Act, which had not addressed them. To fulfil this goal, the author asked several research questions: What forms of use of copyright works refer to the terms...

Incremental Model Transformation with Epsilon in Model-Driven Engineering

Marzieh Ghorbani, Mohammadreza Sharbaf, Bahman Zamani

Acta Informatica Pragensia 2022, 11(2), 179-204 | DOI: 10.18267/j.aip.1792737  

Model-Driven Engineering (MDE) is a software development paradigm that uses models as the main artifacts in the development process. MDE uses model transformations to propagate changes between source and target models. In some development scenarios, target models should be updated based on the evolution of source models. In such cases, it is required to re-execute all transformation rules to update the target model. Incremental execution of transformations, which partially executes the transformation rules, is a solution to this problem. The Epsilon Transformation Language (ETL) is a well-known model transformation language that does not support incremental...

Gender Recognition Based on Hand Thermal Characteristic

Katerina Prihodova

Acta Informatica Pragensia 2022, 11(2), 205-217 | DOI: 10.18267/j.aip.1802272  

Automatic gender recognition is one of the frequently solved tasks in computer vision. It is useful for analysing human behaviour, intelligent monitoring or security. In this article, gender is recognized based on multispectral images of the hand. Hand (palm and back) images are obtained in the visible spectrum and thermal spectrum; then a fusion of images is performed. Some studies say that it is possible to distinguish male and female hands by some geometric features of the hand. The aim of this article is to determine whether it is possible to recognize gender by the thermal characteristics of the hand and, at the same time, to find the best architecture...

Exploring Facebook Identity Construction of Vietnamese Netizens

Hai Chung Pham, Lien Nguyen, Phuong Tran, Thuy Tran

Acta Informatica Pragensia 2022, 11(2), 218-240 | DOI: 10.18267/j.aip.1814591  

Studying the ways in which people construct their identities in online environments is a pressing contemporary concern. The research reported in this article was designed to examine the uses of, and influences on, Vietnamese respondents’ identity formation on Facebook. Data were collected by means of a social survey and the application of the Zaltman metaphor elicitation technique, a procedure that searches for customers’ thoughts and emotions by digging deep into the visual and non-visual illustrations that customers collect or make on their own. The findings show how Vietnamese Facebook users present themselves and how they thereby facilitate...

Use of FURIA for Improving Task Mining

Petr Průcha, Jan Skrbek

Acta Informatica Pragensia 2022, 11(2), 241-253 | DOI: 10.18267/j.aip.1832074  

Companies that use robotic process automation very often deal with the problem of selecting a suitable process for automation. Manual selection of a suitable process is very time-consuming. Therefore, part of the process mining field specializes in selecting suitable processes for automation based on process data. This work deals with the possibility of improving the existing method for finding suitable candidates for automation. To improve the current approach, we remove the limiting restrictions of the current method and use another FURIA rule-learning algorithm for rule detection. We use three different datasets and the WEKA platform to validate...

Increasing Efficiency in Inventory Control of Products with Sporadic Demand Using Simulation

Katerina Huskova, Jakub Dyntar

Acta Informatica Pragensia 2022, 11(2), 254-264 | DOI: 10.18267/j.aip.1842411  

The goal of this paper is to examine whether, in Q-system inventory control policy, a combination of the reorder point exceeding order quantity leads to minimal holding and ordering costs when dealing with sporadic demand. For this purpose, a past stock movement simulation is applied to a set of randomly generated data with different numbers of zero demand periods ranging from 10 to 90%. The outputs of the simulation prove that in situations where stock holding costs are too high, the simulation tends to reduce average stock by overcoming periods between two demand peaks with an increase in the numbers of small replenishment orders and reaches lower...

Service Desk Onboarding Training Environment

Michal Dostál

Acta Informatica Pragensia 2022, 11(2), 265-284 | DOI: 10.18267/j.aip.1884119  

Low qualification of employees newly hired to service desks contributes to the high turnover of service desk agents and consequently to low quality of services delivered. This paper proposes a conceptual artefact comprising two modules for tacit knowledge elicitation and knowledge transfer during the onboarding training process. The design of the artefact follows the design science methodology. Ex-ante evaluation methods are chosen to evaluate the importance of a problem domain and evaluate the artefact feasibility. Expert interviews and focus group discussions with experts from the field were performed to support the evaluation activities. The proposed...

What is the Real Threat of Information Explosion?

Petr Strossa

Acta Informatica Pragensia 2022, 11(2), 285-289 | DOI: 10.18267/j.aip.1851808  

The text is devoted to a consideration of the “information explosion” phenomenon. The exponential growth of publications is compared to the (similarly exponential) growth of population, especially in the countries where most of the publications are created. The increasing tertiary education gross enrolment ratio (naturally associated with involvement in the publication process) is also taken into account. The text comes to a conclusion that either the exponential growth of publications must decrease its base value in our future, or we are heading towards a time point where an increasing number of publications find no readers (if that point...
