The objective of this article is to conceptually transfer the concept of open source software (OSS) development to scientific entrepreneurship and to hypothetically discuss the support potentials of this rather new development philosophy for what we than call open scientific entrepreneurship. Therefore, at first the authors will go into conceptual details of scientific entrepreneurship and than...

This article introduces an approximation space for graded acceptance of proposed models for intelligent system design relative to design patterns that conform to a design standard. A fundamental problem in system design is that feature values extracted from experimental design models tend not to match exactly patterns associated with standard design models. It is not generally known how to meas...

Design patterns are graceful solutions to specific software design problems. However, choosing proper design patterns for given software design problems might not be an easy task especially for novice developers. The design patterns searching tools are therefore needed to solve the problem. One major problem of the existing researches in this field is the indexing problem. This paper aims to so...

A designer often has to evaluate alternative designs during the development of a system. A multitude of Design-Space Exploration (DSE) techniques exist in the literature. Integration of these techniques into the modelling paradigm is needed when a model-driven engineering approach is used for designing systems. To a greater or lesser extent, the integration of those different DSE techniques sha...

At MITRE we are developing tools to aid analysts in assessing the operational usability and quality of object-oriented code. Our tools statically examine source code, automatically recognize the use of design patterns and relate pattern use to software qualities, coding goals, and system engineering expectations about the source code. Thus, through the use of automated design pattern analysis, ...

Patterns have shown to be an effective means of capturing and communicating software design experience. However, there is more to patterns than software design patterns: We believe that patterns work for software development on several levels. In this paper we explore what we have come to understand as crucial aspects of the pattern concept, relate patterns to the different models built during ...

In this paper we describe a novel method for producing interactive systems design patterns form ethnographic studies involving these systems. It is argued that this process can lead to traceable production of design patterns. A software environment, ColAT, that can support the proposed process, is also described.

The evaluation of intelligent tutoring systems (ITSs) is an important though often neglected stage of ITS development. There are many evaluation methods available but literature does not provide clear guidelines for the selection of evaluation method(s) to be used in a particular context. This paper describes the evaluation study of DEPTHS, an intelligent tutoring system for learning software d...
