Title: AHP Model for the Big Data Analytics Platform Selection
Abstract: Big data analytics refers to a set of advanced technologies, which are designed to efficiently operate and maintain data that are not only big, but also high in variety and velocity. This paper analyses these emerging big data technologies and presents a comparison of the selected big data analytics platforms through the whole data life. The main aim is then to propose and demonstrate the use of an AHP model for the big data analytics platform selection, which may be used by businesses, public sector institutions as well as citizens to solve multiple criteria decision-making problems. It would help them to discover patterns, relationships and useful information in their big data, make sense of them and to take responsive action.

Title: Proposal of Decision-making Model Using the DeLone and McLean’s Information System Success Model Together with the AHP
Abstract: The focus of the paper is to present an evaluation of a proposed decision-making model concept. The concept takes into account the quality of a currently used information system’s subsystem (the Business Intelligence subsystem in our case), as it is perceived by its current users. The Analytic Hierarchy Process (AHP) multi-criteria decision making method is used to support the concept with a hierarchical decision criteria structuring framework. A selected part of the DeLone and McLean’s (D&M) information system success assessment model is used for the determination of appropriate criteria (success factors). The D&M model is composed of information system quality assessment dimensions. These dimensions represent a solid base for surveying information system’s users according to their perception of key information system performance aspects. The presented model helps to combine opinions of the management and users successfully when carrying out important information system related decision. The results also illustrate the possibility of using the D&M model in a novel application together with the AHP method.

Title: Measures of quality of process models created in BPMN
Abstract: Description, documentation, evaluation and redesign of key processes during their execution should be an essential part of the strategic management of any organization. All organizations live in a dynamically changing environment. Therefore they must adapt its internal processes to market changes. These processes must be described. Suitable way of description could be BPMN notation. Right after description of processes via BPMN, processes should be controlled to ensure expected of their quality. System (which could be automated) based on mathematical expression of qualitative characteristics of process models (i.e. measures of quality of process models) can support mentioned process controls. Research team trying to design and get into practical use such a tool. The aim of this publication is description of mentioned system - based on measures of the quality of process models - and answer associated scientific questions.

Title: Color Mapping on Common Use-Cases in a Web Application
Abstract: Psychology of Colors and its application in software is a part of a wider research related to Software Ergonomics. Nowadays, software tends to be faster, clever and even more complex. On the other side, the amount of applications, which people has to manage increases. However, user interface and all the communication between a man and a machine needs simplifying. One way how to do that is to dig into the knowledge and conventions, which users already have. Software needs to be brought near to the users maybe using the associations of the particular use-cases in the application with colors, which users already know and which are common to them. The research tries to find these associations, describe them and define the steps for the future research.

Title: Modified Ishikawa Diagram as a Tool for Knowledge-Mapping of Agronomic Practices
Abstract: This article describes a novel method of graphical representation of agronomic practices in crop production. The influence of initial factors, the need to follow a chronology of individual operations and the possibility of using this information for creating a knowledge base are all considered in the method designed. Consequently, alternate methods of knowledge mapping are described: Mind maps, conceptual maps, cognitive maps as well as Ishikawa diagram, which is the main inspiration for our method. These established methods of knowledge mapping have been confronted with the method proposed by our research team using a qualitative survey. Results of this study suggest a high potential of use of our method in agronomy. At the end of this article, we propose additional steps for possible improvements in usability of the method described.

Title: Predatory Open Access Publishers and other Dangers to Today’s Scientific Community
Abstract: The aim of this paper is to introduce a summary and current state of the issue of predatory open access publishers and to critically discuss general predatory behaviour and related topics in the Czech and international context. The article summarizes outputs of the first foreign studies dealing with predatory publishers and journals. We find that although in the past three years, the issue of predation is actively addressed in foreign countries, the Czech higher education institutions are not prepared for this new phenomenon as well as most of academics and researchers do not know about it at all. The text highlights the threats with which the scientific community (science and education in general) is confronted and proposes countermeasures from the view of an individual and higher education institutions. At the end of the article, there are mentioned trends in the behaviour of predatory publishers and dilemmas which non-predatory journal publishers and international indexing databases are faced with.
