  abstract = {Active involvement of end users in the development of interactive systems is both highly recommended and highly challenging. This is particularly true in settings where the requirements of a large number of geographically distributed users have to be taken into account. In this paper, we address this problem by introducing an integrated, web-based approach that enables users to easily express their ideas on how the interaction with a system could be improved. In addition, the user input is contextualized, allowing for highly structured means to access, explore, and analyze the user requirements.},

 Ontologie-Editor iMERGE erlaubt nicht nur die Erzeugung aussagekräftiger visueller Darstellungen,
 sondern ermöglicht auch ein hohes Maß an Interaktion. Dies bezieht sich sowohl auf die Steuerung der
 visuellen Repräsentation der Ontologie, als auch auf die Interaktion mit den Ergebnissen des Vergleichssprozesses.},

 of interactive visualizations with the merging process enabling the
 user to follow why concepts are merged and at which position in the
 ontology they are merged. For this purpose, adapted ontology similarity
 measures and new techniques for representing ontologies will be required
 to enable responsive, real time visualization and exploration of the comparing
 and merging results.},

  abstract = {Understanding the relationships between require- ments is important in order to understand the requirements themselves. Existing requirements management tools mainly use lists, tables, trees, and matrices to visualize requirements and their interrelations. However, all these visualization forms have a limited capability to show multiple relationships of different types. In this paper, we propose to extend traditional requirements analysis and management by a graph-based visualization that allows to represent multidi- mensional relations in a direct and flexible way. In particular, we propose a special presentation form that enables the exploration of requirements along their relationships and facilitates understanding of dependencies between requirements.},

  abstract = {One of the main challenges in distributed software development is the elicitation and management of knowledge regarding system requirements. Due to spatial distribution of involved parties, many limitations concerning interaction, communication, and conceptualization have to be faced. The SoftWiki project aims to provide an agile, wiki-based methodology to overcome these limitations in part. This paper introduces the SoftWiki approach and presents some of the tools that are developed to support knowledge sharing in distributed requirements engineering.},
