Requirements Engineering (RE) spielt in der Software Entwicklung eine entscheidende Rolle. Verschiedene Studien haben gezeigt, dass viele Projekte durch unzureichendes RE scheitern. Aus diesem Grund ist eine gezielte Anforderungsanalyse mit der Einbindung aller relevanten Stakeholder erfolgsentscheidend. Existierende ...

In this paper, we present the ImageNotion tool that allows for the semantic annotation of images and image parts together with the maturing of ontologies in a work integrated environment. The tool uses our ImageNotion methodology for ontology development.

Die webbasierte, verteilte Anforderungserhebung geht mit Herausforderungen einher, die neuartige Partizipations- und Interaktionsformen notwendig machen. Vor diesem Hintergrund präsentieren wir im vorliegenden Beitrag Lösungsansätze, die im Rahmen des SoftWiki-Projekts entwickelt werden. Zunächst erläutern und vergleichen ...

Requirements Engineering ist eine erfolgsentscheidende Phase von Software-Entwicklungsprojekten, welche sich besonders dadurch auszeichnen, dass viele verschiedene Stakeholder gemeinsam Ziele, Szenarien und Anforderungen für das geplante System erheben. Neben der Entwicklung eines Vorgehens für ein semantisch unterstütztes ...

The proliferation of Geo-Information (GI) production in web-based collaboration environments such as mapping mashups built on top of mapping APIs such as GoogleMaps API poses new challenges to GI Science. In this environment, millions of users are not only consumers of GI but they are also producers. A major challenge ...

In recent years social bookmark systems like del.icio.us Furl have become increasingly popular. These systems sometimes are regarded as alternatives to algorithmic search engines like Google. In this paper we develop seven theses on the potential of these systems in order to establish a conceptual basis for future research ...

The Relationship Finder is a tool for exploring connections between objects in a Semantic Web knowledge base. It offers a new way to get insights about ele- ments in an ontology, in particular for large amounts of instance data. For this reason, we applied the idea to the DBpedia data set, which contains an enormous ...
