Use case diagrams are the core diagrams of the Unified Modeling Language (UML), de facto standard for software modeling. They are used to visualize relations between the users (Actors) and the functionality of the software system (Use Cases). Galois sub hierarchy (GSH) is a sub-order of the concept lattice that contains only concepts with object or attribute labels. This paper investigates the ...

Current Enterprise Resource Planning (ERP) systems are based on double entry bookkeeping. This technique has several disadvantages concerning application neutral financial data storage. Therefore, the Resource Event Agent (REA) ontology was introduced to negotiate the current drawbacks. It describes concepts and its relationships semantically. Nevertheless, there exist a set of different REA mo...

A home network system consists of multiple networked appliances, intended to provide more convenient and comfortable living for home users. Before being deployed, one has to guarantee the correctness, the safety and the security of the system. Here, we present the approach chosen to validate the Java implementation of one home network system. We relies on the Java Modeling Language (JML), to fo...

The Unified Modeling Language (UML) is rapidly emerging as a de-facto standard for modelling OO systems. Given this role, it is imperative that the UML have a welldefined, fully explored semantics. Such semantics is required in order to ensure that UML concepts are precisely stated and defined. In this paper we describe and motivate an approach to formalizing UML in which formal specification t...

Formal methods are considered to be highly expensive. Therefore, they are currently applied almost only in high risk software development. In this paper, we show that formal techniques can be also efficiently used in standard large-scale applications. We focus on the generation of specifications which state the termination condition of for loops in Java code (expressed as so called Java Modelin...

In the surface mining industry, the cost of workplace-related accidents is high in terms of downtime and equipment repair. Training operators how to safely inspect and operate their vehicles is the major part of any training program. Traditional training methods are often expensive, ineffective, or even life-threatening. As a result, the mining industry is constantly searching for better traini...

To enable scalability and address the needs of real-world software, deductive verification relies on modularization of the target program and decomposition of its requirement specification. In this paper, we present an approach that, given a Java program and a partial requirement specification written using the Java Modeling Language, constructs a semantic slice. In the slice, the parts of the ...

Business process modeling has become a popular method for improving organizational efficiency and quality. Automatic validation of process models is one of the most valuable features of modeling tools, in face of the increasing complexity of enterprise business processes and the richness of modeling languages. This paper proposes a formal language, Event-Condition-Action-Event (ECAE), for integ...

As part of our charge from the Virtual Sockets Interface Alliance we search for a notation in which standards documents can be precisely specified. We approach the specification for standard problem in the context of the Virtual Component Interface Standard. We propose six orthogonal axes of specification as guides to creating a cohesive, well-rounded requirements specification. We then specify...

The Specification and Description Language (SDL) is a domain specific language that is well-established in the telecommunication sector since many years, but only a small set of SDL tools is available. In contrast, for the Unified Modeling Language (UML) a wide range of different kinds of tools can be used for various purposes, such as model transformation. In order to makes it possible to spec...
