In this paper, we propose a new approach for managing domain specific thesauri, where object-oriented paradigm is applied to thesaurus construction and query-based browsing. The approach provides an object-oriented mechanism to assist domain experts in constructing thesauri; it determines a considerable part of relationship degrees between terms by inheritance and supplies the domain expert with information available from other parts of the thesaurus being constructed or already constructed. In addition to that, it enables domain experts to incrementally construct the thesaurus, since the automatically determined relationship degrees can be refined whenever a more sophisticated thesaurus is needed. It may minimize domain experts' burden caused by the exhaustive specification of individual relationship. This approach also provides a query-based browsing facility, which enables users to find desired thesaurus terms without tedious browsing in the thesaurus. A browsing query can be formulated with terms rather ambiguous, yet capable of deriving the desired terms. This browsing query is useful especially when users want precise results. In other words, it is useful when they want to use only thesaurus terms carefully selected in reformulating Boolean queries. To demonstrate the feasibility of our approach, we fully implemented an object-based thesaurus system, which supports the semiautomatic thesaurus construction and the query-based browsing facility.

In general, designing a domain-specific language (DSL) is a complicated process, requiring the cooperation of experts from both application domain and computer language development areas. One of the problems that may occur is a communication gap between a domain expert and a language engineer. Since domain experts are usually non-technical people, it might be difficult for them to express requirements on a DSL notation in a technical manner. Another compelling problem is that even though the majority of DSLs share the same notation style for representing the common language constructs, a language engineer has to formulate the specification for these constructs repeatedly for each new DSL being designed. The authors propose an innovative concept of computer language patterns to capture the well-known recurring notation style often seen in many computer languages. To address the communication problem, they aim for the way of proposing a DSL notation by providing program examples as they would have been written in a desired DSL. As a combination of these two ideas, the chapter presents a method for example-driven DSL notation specification (EDNS), which utilizes computer language patterns for semi-automated inference of a DSL notation specification from the provided program examples.

Different classes of problems on the embedded systems market and its needs make manufacturers of embedded systems to design heterogeneous many/multi core hardware platforms. Such platforms includes dozens of different cores: CPU, GPU, DSP, FPGA etc. That makes them incredibly hard to program, especially in case when domain experts are involved in the development process. Usually, domain expert has knowledge in his domain area, but does not fully understand the specificity of programming for heterogeneous manycore platforms. In this article, we propose the complex technology and tools that allows involving domain experts in software development for embedded systems. The proposed technology has various aspects and abilities that can be used to build verifiable and portable software for a wide range of heterogeneous embedded platforms.

Specific Modeling

Enterprise resource planning (ERP) systems are often seen as viable sources of data for process mining analysis. To perform most of the existing process mining techniques, it is necessary to obtain a valid event log that is fully compliant with the eXtensible Event Stream (XES) standard. In ERP systems, such event logs are not available as the concept of business activity is missing. Extracting event data from an ERP database is not a trivial task and requires in-depth knowledge of the business processes and underlying data structure. Therefore, domain experts require proper techniques and tools for extracting event data from ERP databases. In this paper, we present the full specification of a domain-specific modeling language for facilitating the extraction of appropriate event data from transactional databases by domain experts. The modeling language has been developed to support complex ambiguous cases when using ERP systems. We demonstrate its applicability using a case study with real data and show that the language includes constructs that enable a domain expert to easily model data of interest in the log extraction step. The language provides sufficient information to extract and transform data from transactional ERP databases to the XES format.

This paper investigates what matters to medical domain experts when setting standards on a language for specific purposes (LSP) English proficiency test: the Occupational English Test’s (OET) writing sub-test. The study explores what standard-setting participants value when making performance judgements about test candidates’ writing responses, and the extent to which their decisions are language-based and align with the OET writing sub-test criteria. Qualitative data is a relatively under-utilized component of standard setting and this type of commentary was garnered to gain a better understanding of the basis for performance decisions. Eighteen doctors were recruited for standard-setting workshops. To gain further insight, verbal reports in the form of a think-aloud protocol (TAP) were employed with five of the 18 participants. The doctors’ comments were thematically coded and the analysis showed that participants’ standard-setting judgements often aligned with the OET writing sub-test criteria. An overarching theme, ‘Audience Recognition’, was also identified as valuable to participants. A minority of decisions were swayed by features outside the OET’s communicative construct (e.g., clinical competency). Yet, overall, findings indicated that domain experts were undeniably focused on textual features associated with what the test is designed to assess and their views were vitally important in the standard-setting process.

This paper uses concepts from sheaf theory to explain phenomena in concurrent systems, including object, inheritance, deadlock, and non-interference, as used in computer security. The approach is very; general, and applies not only to concurrent object oriented systems, but also to systems of differential equations, electrical circuits, hardware description languages, and much more. Time can be discrete or continuous, linear or branching, and distribution is allowed over space as well as time. Concepts from categpru theory help to achieve this generality: objects are modelled by sheaves; inheritance by sheaf morphisms; systems by diagrams; and interconnection by diagrams of diagrams. In addition, behaviour is given by limit, and the result of interconnection by colimit. The approach is illustrated with many examples, including a semantics for a simple concurrent object-based programming language.
