Ontology driven development of domain-specific languages
Ines Čeh, Matej Črepinšek, Tomaž Kosar, Marjan Mernik, 2011, original scientific article

Abstract: Domain-specific languages (DSLs) are computer (programming, modeling, specification) languages devoted to solving problems in a specific domain. Thedevelopment of a DSL includes the following phases: decision, analysis, design, implementation, testing, deployment, and maintenance. The least-known and least examined are analysis and design. Although various formal methodologies exist, domain analysis is still done informally most of the time. A common reason why formal methodologies are not used as often as they could be is that they are very demanding. Instead of developing a new, less complex methodology, we propose that domain analysis could be replaced with a previously existing analysis in another form. A particularly suitable form is the use of ontologies. This paper focuses on ontology-based domain analysis and how it can be incorporated into the DSL design phase. We will present the preliminary results of the Ontology2DSL framework, which can be used to help transform ontology to a DSL grammar incorporating concepts from a domain.

On automata and language based grammar metrics
Matej Črepinšek, Tomaž Kosar, Marjan Mernik, Julien Cervelle, Rémi Forax, Gilles Roussel, 2010, original scientific article

Abstract: Grammar metrics have been introduced to measure the quality and the complexity of the formal grammars. The aim of this paper is to explore the meaning of these notions and to experiment, on several grammars of domain specific languages and of general-purpose languages, existing grammar metrics together with the new metrics that are based on grammar LR automaton and on the language recognized. We discuss the results of this experiment and focus on the comparison between grammars of domain specific languages as well as of general-purpose languages and on the evolution of the metrics between several versions of the same language.

Investigation of moderator factors in e-business adoption
Boštjan Šumak, Marjan Heričko, Zoran Budimac, Maja Pušnik, 2017, original scientific article

Abstract: E-business technology is becoming one of the most important global markets where e-business solutions will have to adapt to new technologies. The main objective in this study was to synthesize existing knowledge in the field of e-business technology acceptance and to understand differences in Technology Acceptance Model (TAM) related causal effect sizes for different e-business contexts. A quantitative meta-analysis of existing empirical research about factors affecting e-business adoption was conducted using 89 published papers that provided empirical data about causal relationships. A moderator analysis was carried out to investigate the moderating effect of four factors: consumer type, device type, continent and respondent type. The results of the study showed a moderating effect for all four proposed factors in almost all TAM-related causal paths. The study also showed that TAM is the most common theory being applied in e-business adoption research.

Implementation of EasyTime formal semantics using a LISA compiler generator
Iztok Fister, Marjan Mernik, Iztok Fister, Dejan Hrnčič, 2012, original scientific article

Abstract: A manual measuring time tool in mass sporting competitions would not be imaginable nowadays, because many modern disciplines, such as IRONMAN, last a long-time and, therefore, demand additional reliability. Moreover, automatic timing-devices based on RFID technology, have become cheaper. However, these devices cannot operate as standalone because they need a computer measuring system that is capable of processing incoming events, encoding the results, assigning them to the correct competitor, sorting the results according to theachieved times, and then providing a printout of the results. This article presents the domain-specific language EasyTime, which enables the controlling of an agent by writing the events within a database. It focuses, in particular, on the implementation of EasyTime with a LISA tool that enables the automatic construction of compilers from language specifications, using Attribute Grammars.

From DCOM interfaces to domain-specific modeling language
Tomaž Kos, Tomaž Kosar, Jure Knez, Marjan Mernik, 2011, original scientific article

Abstract: Software development is a demanding process, since it involves different parties to perform a desired task. The same case applies to the development ofmeasurement systems - measurement system producers often provide interfaces to their products, after which the customersć programming engineers use them to build software according to the instructions and requirements of domain experts from the field of data acquisition. Until recently, the customers of the measurement system DEWESoft were building measuring applications, using prefabricated DCOM objects. However, a significant amount of interaction between customersć programming engineers and measurement system producers is necessary to use DCOM objects. Therefore, a domain-specific modeling language has been developed to enable domain experts to program or model their own measurement procedures without interacting with programming engineers. In thispaper, experiences gained during the shift from using the DEWESoft productas a programming library to domain-specific modeling language are provided together with the details of a Sequencer, a domain-specific modeling language for the construction of measurement procedures.

Experimental investigation of the quality and productivity of software factories based development
Andrej Krajnc, Marjan Heričko, Črt Gerlec, Uroš Goljat, Gregor Polančič, 2012, original scientific article

Abstract: Software organizations are always looking for approaches that help improve the quality and productivity of developed software products. Quality software is easy to maintain and reduces the cost of software development. The Software Factories (SF) approach is one of the approaches to provide such benefits. In this paper, the quality and productivity benefits of the SF approach were examined and evaluated with an experiment involving two treatments - the traditional and the SF approach. For the purposes of this experiment, the Goal – Question – Metric (GQM) approach was used. Participants were grouped into thirty two teams. There were sixteen projects available. The results were evaluated and presented through quality and productivity criteria, which were used for the experimental study. The results showed that the Software Factories approach was significantly better than the traditional approach.

Design of a multimodal hearing system
Bernd Tessendorf, Matjaž Debevc, Peter Derleth, Manuela Feilner, Franz Gravenhorst, Daniel Roggen, Thomas Stiefmeier, Gerhard Tröster, 2013, original scientific article

Abstract: Hearing instruments (HIs) have become context-aware devices that analyze the acoustic environment in order to automatically adapt sound processing to the userʼs current hearing wish. However, in the same acoustic environment an HI user can have different hearing wishes requiring different behaviors from the hearing instrument. In these cases, the audio signal alone contains too littlecontextual information to determine the userʼs hearing wish. Additional modalities to sound can provide the missing information to improve the adaption. In this work, we review additional modalities to sound in HIs and present a prototype of a newly developed wireless multimodal hearing system. The platform takes into account additional sensor modalities such as the userʼs body movement and location. We characterize the system regarding runtime, latency and reliability of the wireless connection, and point out possibilities arising from the novel approach.

Comparing general-purpose and domain-specific languages
Tomaž Kosar, Nuno Oliveira, Marjan Mernik, Maria João Varando Pereira, Matej Črepinšek, Daniela Da Cruz, Pedro Rangel Henriques, 2010, original scientific article

Abstract: Many domain-specific languages, that try to bring feasible alternatives for existing solutions while simplifying programming work, have come up in recent years. Although, these little languages seem to be easy to use, there is an open issue whether they bring advantages in comparison to the application libraries, which are the most commonly used implementation approach. In this work, we present an experiment, which was carried out to compare such a domain-specific language with a comparable application library. The experimentwas conducted with 36 programmers, who have answered a questionnaireon both implementation approaches. The questionnaire is more than100 pages long. For a domain-specific language and the application library, the same problem domain has been used - construction of graphical user interfaces. In terms of a domain-specific language, XAML has been used and C# Forms for the application library. A cognitive dimension framework has been used for a comparison between XAML and C# Forms.

Challenges and directions in formalizing the semantics of modeling languages
Barrett Richard Bryant, Jeffrey G. Gray, Marjan Mernik, Peter Clarke, Robert France, Gabor Karsai, 2011, original scientific article

Abstract: Developing software from models is a growing practice and there exist many model-based tools (e.g., editors, interpreters, debuggers, and simulators) forsupporting model-driven engineering. Even though these tools facilitate theautomation of software engineering tasks and activities, such tools are typically engineered manually. However, many of these tools have a common semantic foundation centered around an underlying modeling language, which would make it possible to automate their development if the modeling language specification were formalized. Even though there has been much work in formalizing programming languages, with many successful tools constructed using such formalisms, there has been little work in formalizing modeling languages for the purpose of automation. This paper discusses possible semantics-based approaches for the formalization of modeling languages and describes how this formalism may be used to automate the construction of modeling tools.

Business process model and notation
Mateja Kocbek, Gregor Jošt, Marjan Heričko, Gregor Polančič, 2015, original scientific article

Abstract: With business process modelling, companies and organizations can gain explicit control over their processes. Currently, there are many notations in the area of business process modelling, where Business Process Model and Notation (BPMN) is denoted as the de facto standard. Aims: The aim of this research is to provide the state-of-the-art results addressing the acceptance of BPMN, while also examining the purposes of its usage. Furthermore, the advantages, disadvantages and other interests related to BPMN were also investigated. Method: To achieve these objectives, a Systematic Literature Review (SLR) and a semantic examination of articles% citations was conducted. Results: After completing SLR, out of a total of 852 articles, 31 were deemed relevant. The majority of the articles analyzed the notation and compared it with other modelling techniques. The remainder evaluated general aspects of the notation, e.g. history and versions of the standard, usage of the notation or tools. Conclusion: Our findings demonstrate that there are empirical insights about the level of BPMN acceptance. They suggest that BPMN is still widely perceived as the de facto standard in the process modelling domain and its usage is ever-increasing. However, many studies report that only a limited set of elements are commonly used and to this end, several extensions were proposed. The main purpose of BPMN remains the description of business processes.
