MAGISTERARBEIT ReUse Cases: Supporting Knowledge Management and Reuse with Self-Organizing Use Case Maps

Organizations in today’s software industry are increasingly faced with the challenge of managing information about their past, present, and future projects. The effective and efficient reuse of past knowledge, experience, and assets is one of the key success factors in the software business. To organize the huge number of documents arising during software projects, e. g. use case documents, a digital library offering content-based organization may be used. It allows the user to explore and analyze a potentially unknown library in an intuitive way. In software reuse, finding suitable reuse candidates for a more or less accurately specified problem is one of the critical questions. In knowledge managment, an important issue is finding correct sources of tacit knowledge. Mapping the use cases of a new project to the existing collection may reveal valuable similarities that might not be uncovered by traditional information retrieval methods like key-word based search. This thesis investigates a digital library system based on self-organizing map

Collaboration is an intriguing and promising aspect in Virtual and Augmented Reality systems, whether participants are co-located or not. At least, distant collaboration requires distribution capabilities to replicate the Virtual Environment on all participating sites. Studierstube is a Collaborative Augmented Reality system, providing reliable distribution in a limited way. This thesis extends these capabilities to long distance distribution, supporting ordinary IP-based networks like the Internet. Collaboration between participants located in different cities, countries and even continents becomes possible. In order to apply these new features, Construct3D, a dynamic geometric construction tool in 3D for educational purposes, was adapted. By reducing the data amount to transmit, distribution efficiency was increased. Furthermore, robustness, flexibility and scalability capabilities were improved. Distribution and collaboration features directly profit from all of these efforts. Zusammenfassun
