Therefore, this method is introduced to new developers constantly. The paper investigates possibility for overlooking ontology features that can enable users to properly represent semantics of the domain of interest. In initial research, ontology development using frames was considered and evaluation was made based on criteria connected to classes, hierarchy and attributes. Possible beginner oversights are identified. Suggestions considering chosen semantic criteria are also described.
EMAN 2019 – Economics & Management: How to Cope With Disrupted Times CONFERENCE PROCEEDINGS, 2019

Rapid changes cause disruption of organizations, especially new information technologies and organizations that are born digital. To cope, many organizations undergo digital transformation and change their business models. In such conditions, knowledge management is more important than ever, but the question is whether companies recognize its large potentials, from supporting digital business and digital workforce to preserving and delivering critical knowledge at any time. In this paper we discuss benefits that knowledge management can give organizations in disruptive times together with issues and challenges that arise. Also, an overview of new information technologies that may be incorporated into knowledge management systems and contribute to those benefits is presented, such as technologies connected to artificial intelligence. This leads to examination how disruptive times and technologies change knowledge management itself and whether and how they affect processes of creating, managing, sharing and using organizational knowledge.

Knowledge management is the key factor in achieving this goal and consequently in a development of a successful organization. This approach to handling organisation’s knowledge assets includes various elements and processes and has several supportive infrastructure elements, one of them being information technology. Implementation of knowledge management nowadays implies, or is even unimaginable without the use of at least some of this technology. Because of its importance, there is a wealth of information technology solutions for knowledge management aimed at various purposes and types of organizations, covering some aspects or offering integrated solution. This paper gives an overview of literature covering the research of use of information technology for knowledge management. It also gives...

Previous research, mostly concentrated on object-oriented programming, has shown that students face various obstacles in learning programming languages, which resulted in suggestions for improving teaching process in this field. Logic programming, belonging to a different, declarative programming paradigm, has been researched to a smaller extent, although it raises even bigger challenges for both students and teachers. Students are recommended to first acquire knowledge in formal logic, and then to learn how to apply that knowledge in logic programming. This paper addresses teaching formal logic and especially logic programming. As a first step in initiative for its improvement, an overview of existing logic programming teaching resources is made, with the emphasis on freely available online courses, materials and tools.

These problems are even more evident in the case of students with different types of disabilities. The number of software tools for education of programming for such students is continually growing, mostly in the case of tools for visually impaired. Many universities are offering various services to help these students in achieving their goals in all fields of study, and students are also directed to use a variety of assistive technologies, according to their disabilities. On the other side, teachers are advised to make their courses more accessible to students with disabilities. The aim of this paper is to discuss to what extent this technology, aimed at all degree programs, can be combined with other e...
Some Issues Concerning the Ontology Development Process

In our paper several directions will be discussed regarding: (a) expressing constraints in ontologies using first order logic and description logic, (b) complexity of ontology extension both in depth (for example, from domain ontology to application ontology) and in width (broadening of the domain), and (c) usage of combination of various ontology evaluation methods. Paper presents one part of the work on the project "Development of information infrastructure and deductive mechanisms of Semantic Web", funded by Ministry of science, education and sport in Croatia.

S porastom popularnosti igrifikacije u akademskom i industrijskom okruženju razvijeni su i koriste se brojni termini koji često imaju vrlo slično značenje, što stvara nedoumice i poteškoće kod njihova korištenja. Dodatan problem se javlja kod pokušaja prevođenja tih termina s engleskog na hrvatski jezik zbog različitih sintagmi koje se koriste u navedenim jezicima. Stoga je u ovom radu napravljen sistematizirani pregled najvažnijih i najčešćih termina vezanih uz područje igrifikacije te njezinih sudionika i elemenata. Također su predloženi nazivi standardnih termina, kao i njihove definicije.

This fact results in some of potential disabled students not enrolling in higher education institutions or not finishing their studies. In this paper an overview of disabilities, problems and barriers that students with different disabilities encounter in their higher education is given. Models of disability and methods for aiding students with disabilities are also stated and elaborated.

Namely, a term "loophole in the law" is well known. Examples of such a domain are also studies at Croatian universities, as well as ontology of one part of Croatian Family Legislation Act that covers motherhood and parenthood terms. Studies at universities example The Bologna process and new higher education legislation in Croatia have made the domain of studies at universities an interesting subject for domain ontology development at the country level. The ontology was developed in several steps. As, first, a domain model was created using TBox of simple description logic language ALC, according to which hierarchy was created in Protégé-OWL and classification was made using Racer tool (http://www.racersystems.com, Copyright (C) 2004, 2005 by Racer Systems GmbH & Co. KG). Model development in such a way automatically opens possib...

In this work, we study the gamification in business context. The mentioned context is very important, due to its usage by companies who are looking for new ways to engage, teach, reward and retain employees and customers. First, we list a state of the art of game studies and a transition from game design to gamification design. We also list main guidelines for application of gamification in business organizations. The effects of gamification and some ethical considerations are also tackled.

Those factors can be considered as crisp or fuzzy. Also, additional elements that influence on the determination of factors are proposed. This approach to the KEL technique selection, using elements, is implemented in a rule-based application with fuzzy reasoning that gives a list of ranked techniques as a result. Application research results were evaluated against research results obtained according to prior knowledge of research subjects in this field. The aim was to see whether there is a need to develop more complex and systematic methods for the KEL technique selection or simpler ones that can be easily made using excerpts from literature can give the same results quality. Proposals for other methods of the KEL technique selection are made.

Although specifically big data analytics has been prominently in the focus of interest, big data management as a whole should be guided properly, so that as much information and knowledge as possible can be obtained from data for their intended purpose. There are many proposed solutions that are trying to resolve various issues that arose with big data, for example weak processing capability of traditional systems, such as relational databases, to efficiently manage them. New technologies that are trying to cope with various unstructured or structured forms of data are also being researched, Hadoop and NoSQL databases being some of them. Big data challenges are also connected with requirements in the domain of their usage, such as business and commerce, healthcare, public sector, education, or scientific research. This paper examines current research of big data management, especially according to its various domains of application. It gives an insight into applications of big data in various domains of different background (business, government, etc.), followed by a discussion on issues and challenges in its application, as well as mechanisms developed to resolve them. Additionally, this paper discusses the benefits and values of using big data solutions in selected domains. The contribution of the paper is also an overview of big data associated differences and similarities among domains that are most researched in the context of this area of interest.
