    Abstract: Reuse and requirements are very important for efficient and successful systems development. This tutorial presents the experiences of requirements reuse using a Method for Requirements Authoring and Management (MRAM). MRAM is a method for establishing and selecting from product line requirements. A product line is a group of products within the same market segment e.g. mobile phones. TRAM (Tool for Requirements Authoring and Management) is a software tool to support MRAM that utilises current proven office technology (MS-Word, MS-Access). The tutorial presents the results of MRAM/TRAM as it has been applied to product line engineering of a real-world application.

    Abstract: Based on our experience and a theoretical comparison, we see an interesting relationship between object-oriented analysis in software engineering and certain aspects of knowledge acquisition in the course of building knowledge-based (expert) systems. In particular, we discuss here issues of modeling and the process dimension, i.e., how to do this modeling. According to this relationship, these fields should be able to stimulate each other.

    Abstract: Software systems and in particular also knowledge-based systems (KBS) become increasingly large and complex. In response to this challenge, software engineering has a long tradition of advocating modularity. This has also heavily influenced object-oriented development. For measuring certain important aspects of modularity, coupling and cohesion metrics have been developed. Metrics have also attracted considerable attention for object-oriented development. For KBS development, however, no such metrics are available yet. This article presents the core of the first metrics suite for KBS development, its coupling and cohesion metrics. These metrics measure modularity in terms of the relations induced between slots of frames through their common references in rules. We show the soundness of these metrics according to theory and report on their usefulness in practice. As a consequence, we propose using our metrics in order to improve KBS development, and developing other important metrics and assessing their theoretical soundness along these lines.

    Abstract: This paper addresses the issue whether hypertext of paper is more appropriate for certain tasks. We chose the task of getting a quick overview of a new topic. We describe the design of a hypertext system with specific emphasis on hierarchical structuring for semi-formal knowledge representation. The domain of our application is hypertext itself. For the evaluation of our design, and more generally hypertext versus paper, we descirbe the experiment and results on the effectiveness of our system compared to a printout version. In particular, we classify the difficulty of the questions posed to the subjects in our experiment accoring to various methods. It is interesting that the achieved classifications have small correlation. There are no statistically significant differences between the performance of subjects using HIS or the paper version. We interpret this as a compensation of the adverse effects of the usually slower reading from a computer screen and unfamiliarity with the medium of hypertext.

    Abstract: Problem solving in the real world is a more general issue than what is currently understood under this notion in the majority of today's AI publications. Particularly, finding an appropriate formal representation of a given problem in the real world is very difficult even for humans. We think that this is reminiscent of the core difficulty of knowledge acquisition for knowledge acquisition for knowledge-based systems, i.e. modeling the real world. If a machine is to understand problem statements in natural language, much commonsense knowledge must be available. However, even if it were available, it would be very difficult to retrieve those chunks of knowledge necessary for the problem at hand. We propose a view of presenting a problem to a problem solver as an act of communication, which may provide hints for finding such knowledge.

    Abstract: This paper is based on experiences with several ports of large programs written in modern high-level languages. Even today, porting software is very often problematic and costly in practice. Thus it seems important to find out what can be learned from such experiences in order to solve these problems better in the future and consequently to reduce the related costs. First, a definition of the term port is given to clarify the important relationships of a program with the environments involved. A layered model is built around the standard of a programming language, and based on this model "rules" for writing portable programs are stated. It appears that both the layered model and the rules are principally valid for many important languages, in particular also Ada & reg;. While this language will bring us a large step closer to portable software, we will have to face portability problems also in the future.

    Abstract: While management of today's software systems is usually performed by humans using some user interface (UI), autonomic systems would be self-managed.Our research addresses the research problem of gradual transition towards self-managed software systems and proposes and investigates a particular architecture for its solution. In particular, we propose unified communication between a system to be managed and its (human or autonomic) manager. Such communication is specified using our high-level discourse metamodel based on insights from theories of human communication. This should make such communication easier to design and understand by humans.

    Abstract: Especially the early phase of requirements engineering is one of the most important and least supported parts of the software life cycle. Since pure natural language has its disadvantages, and directly arriving at a formal representation is very difficult, a link through a mediating representation is missing. We use hypertext for this purpose, providing also links among requirements statements and the representation of objects in a domain model. This possibility of explicit representation of links allows the users and analysts to make relationships and dependencies explicit and helps to be aware of them. Actually, our approach and the tool supporting it use a combination of various technologies, including also object-oriented approaches and a grain of artificial intelligence (in particular frames ). Therefore, inheritance is provided by our tool already in the early phase of requirements engineering. In particular, we found it very useful to view requirements as objects. A key idea is to support the ordering of ideas especially through classification already in the early stages. While our approach is not intended to substitute useful existing techniques emphasizing more formal representations, it can be combined with them.
