Opis: Presented doctoral dissertation describes a research work on Semantic Inference, which can be regarded as an extension of Grammar Inference. The main task of Grammar Inference is to induce a grammatical structure from a set of positive samples (programs), which can sometimes also be accompanied by a set of negative samples. Successfully applying Grammar Inference can result only in identifying the correct syntax of a language. But, when valid syntactical structures are additionally constrained with context-sensitive information the Grammar Inference needs to be extended to the Semantic Inference. With the Semantic Inference a further step is realised, namely, towards inducing language semantics. In this doctoral dissertation it is shown that a complete compiler/interpreter for small Domain-Specific Languages (DSLs) can be generated automatically solely from given programs and their associated meanings using Semantic Inference. For the purpose of this research work the tool LISA.SI has been developed on the top of the compiler/interpreter generator tool LISA that uses Evolutionary Computations to explore and exploit the enormous search space that appears in Semantic Inference. A wide class of Attribute Grammars has been learned. Using Genetic Programming approach S-attributed and L-attributed have been inferred successfully, while inferring Absolutely Non-Circular Attribute Grammars (ANC-AG) with complex dependencies among attributes has been achieved by integrating a Memetic Algorithm (MA) into the LISA.SI tool.

Opis: 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.

Opis: Various implementation approaches for developing a domain-specific language are available in literature. There are certain common beliefs about the advantages/disadvantages of these approaches. However, it is hard to be objective and speak in favor of a particular one, since these implementation approaches are normally compared over diverse application domains. The purpose of this paper is to provide empirical results from ten diverse implementation approaches for domain-specific languages, but conducted using the same representative language. Comparison shows that these discussed approaches differ in terms of the effort need to implement them, however, the effort needed by a programmer to implement a domain-specific language should not be the only factor taken into consideration. Another important factor is the effort needed by an end-user to rapidly write correct programs using the produced domain-specific language. Therefore, this paper also provides empirical results on end-user productivity, which is measured as the lines of code needed to express a domain-specific program, similarity to the original notation, and how error-reporting and debugging are supported in a given implementation.

Opis: Despite the increasing interest in model-driven engineering, there are many open issues that need to be addressed to advance the technology and promote its adoption. This position paper outlines several current limitations of model transformation, with a specific emphasis on model optimization. A primary shortcoming that can be found in many model transformation approaches and tools is the lack of formal semantics to define the meaning of a modeling abstraction. This inadequacy is the source of many problems surrounding the practice of model engineering.

Opis: Measuring time in mass sporting competitions is, typically, performed with a timing system that consists of a measuring technology and a computer system. The first is dedicated to tracking events that are triggered by competitors and registered by measuring devices (primarily based on RFID technology). The latter enables the processing of these events. In this paper, the processing of events is performed by an agent that is controlled by the domain-specific language, EasyTime. EasyTime improves the flexibility of the timing system because it supports the measuring of time in various sporting competitions, their quick adaptation to the demands of new sporting competitions and a reduction in the number of measuring devices. Essentially, we are focused on the development of a domain-specific language. In practice, we made two case studies of using EasyTime by measuring time in two different sporting competitions. The use of EasyTime showed that it can be useful for sports clubs and competition organizers by aiding in the results of smaller sporting competitions, while in larger sporting competitions it could simplify the configuration of the timing system.
