The Unified Modelling Language (UML) is a language for specifying, visualising, constructing and documenting software systems. The UML proved to be extremely successful and it has achieved tremendous popularity making it the de facto industry standard for object oriented system development. As such, many researchers presented empirical studies on the practical usage of UML but as well criticism...

Feature modeling is an important approach to dealing with variability at an abstract level in a hierarchical manner extensively used in software product lines. For its use in conjunction with other UML models and MDA approach, it is important to correctly integrate feature modeling into UML. In this paper, we present an approach to integrating feature modeling into UML that respects abstractnes...

The translation from UML specifications to B specifications may give a way to use jointly UML and B in an unified, practical and rigorous software development. We can formally analyse UML specifications via their corresponding B formal specifications. This point is significant because B support tools are available. We can also use UML specifications as a tool for building B specifications, so t...

Software product line engineering (SPLE) is an emerging approach that enables variability management in software development. SPLE offers tremendous benefits, but lack of tool support becomes a barrier the adoption SPLE. Variability modules for Java (VMJ) implementation defined based on (VM) concept to VMJ combines system and design patterns are commonly used by developers. accompanied UML prof...

The success and proliferation of the Semantic Web depends heavily on construction of Web ontologies. However, classical ontology construction approaches are not sufficient for handling imprecise and uncertain information that is commonly found in many application domains. Therefore, great efforts on construction of fuzzy ontologies have been made in recent years. In this paper, we propose a for...

The Unified Modeling Language (UML) is a language for the specification, visualization, and documentation of object-oriented software systems [The Unified Modeling Language User Guide, 1998]. However, UML cannot describe in an explicit manner the mobility requirements needed for modeling mobile agent-based software systems. In this paper, we present M-UML, our proposed extension to UML covering...

Unified Modeling Language (UML) defines a standard notation for object-oriented systems. Using UML enhances communication between domain experts, workflow specialists, software designers and other professionals with different backgrounds. UML can be used on a general level, which is intuitive for the users of workflow systems. In spite of this, UML symbols also have defined semantics, which mea...

In the paper practical issues concerning the use of UML as a knowledge representation method for rules are discussed. A proposal of an UML-based representation for the XTT structured representation for rules is presented. Since some deep semantical di erences between UML and rule-based representation exist, several possible UML representations are evaluated. A practical algorithm for building a...
