In this paper we partially present an initial version of an Ontology Pattern Language, called S-OPL, describing the core conceptualization of services as a network of interconnected ontology modeling patterns. S-OPL builds on a commitment-based core ontology for services (UFO-S) and has been developed to support the engineering of ontologies involving services in different domains. S-OPL patter...

In this paper, we proposed the Survival Language, a pattern language to support survival when a catastrophic earthquake occurs. This proposal comes from the problem that the tragedies of earthquakes are repeated, because knowledge and wisdom on how to prepare for an earthquake and what to do during an earthquake have not been passed down sufficiently. This paper presented the four patterns of t...

Design patterns have been developed to cope with the vast space of possible different designs within object-oriented systems. One of those classic patterns is the Visitor Pattern that is used for representing an operation to be performed on the elements of an object structure. We present a mapping from the Visitor Pattern to a grammar that defines the set of visit sequences that can be performe...

The expressiveness of traditional syntactic pattern matching is severely limited by its lack of abstraction. Because syntax patterns are mired in the builtin types understood by the pattern matching system, they lack the ability to express patterns over abstract data types (ADT’s). More advanced pattern matching techniques, such as semantic matching, can overcome this, but at the per-ADT cost o...

The objective of this thesis is to study data mining query optimization in a Logicbased Knowledge Discovery Support Environment. i.e, a flexible knowledge discovery system with capabilities to obtain, maintain, represent, and utilize both induced and deduced knowledge. In particular, we focus on frequent pattern queries, since this kind of query is at the basis of many mining tasks, and it seem...

This paper presents the pattern language for specification of communication protocols. The pattern language contains four levels which are used to specify communication protocol and its messages. These four levels of this pattern language are: high-level protocol specification, protocol structure specification, message specification, and detailed message specification. Several existing patterns...

How to get advantages of MVC model without making applications unnecessarily complex? The full-featured MVC implementation is on the top end of ladder of complexity. The other end is meant for simple cases that do not call for such complex designs, however still in need of the advantages of MVC patterns, such as ability to change the look-and-feel. This paper presents patterns of MVC implementa...

At present, the only means used for specifying design patterns are contemporary object notations [Rumbaugh et. al 91; Booch 94], lengthy verbal descriptions, and sample programs. The inherent ambiguity and incompleteness of these means preclude devising tool support and fuel disputes over “their true intention”. We identified a compact set of abstractions with simple graphical representation, w...

Since object-oriented programming is usually associated with iterative development, reverse engineering must be considered an essential facet of the object-oriented paradigm. The reverse engineering pattern language presented here summarises the reverse engineering experience gathered as part of the FAMOOS project, a project with the explicit goal of investigating reverse and reengineering tech...

It is well known that the most difficult and important process within Software Engineering is Requirements Analysis the production of analytic models that accurately and adequately represent the requirements of the system to be built. This paper presents a series of patterns that can be followed in order to produce such models in an object-oriented context.
