Knowledge-intensive activities can typically not be modeled sufficiently by classical, static process models and workflows. To enable a process-oriented knowledge management approach under these circumstances, the concept of weakly-structured workflows has been developed. This approach integrates process modeling and workflow enactment and facilitates(More)
In order to enable knowledge sharing and reuse among software entities, artificial intelligence researchers have proposed to develop ‘ontologies’ as the explicit formal specifications of conceptualizations. These ontologies were normally designed by knowledge engineers who laid down the basic categories and relations for a certain domain. However, in any(More)
Recent research has shown that financial advisory encounters can successfully be supported with IT-artifacts. Tabletop scenarios, for example, can increase the transparency of the advisory process for customers. However, we have also had the experience that the relationship quality as experienced by customers can suffer severely when IT-artifacts are(More)
Today's Web users are faced with a large number of available online communities for every domain. While there are rules-of-thumb for the choice of a specific community, the validity of these heuristics has hardly been tested empirically. Furthermore, there is a lack of well-founded measures that allow for a systematic comparison of different online forum(More)
While social and economic aspects of online communities have been investigated broadly, the information exchanged has seldom been the subject of study. The article follows recent work on using an information systems metaphor for online communities: users specify queries and receive information from the online community members. In order to justify this(More)
The success of the collaboratively created encyclopaedia Wikipedia has already questioned the model of strict separation between professional content authors and readers. Distributed content creation using digital media promises faster updates, more opinions and expertise and large amounts of information produced at virtually no cost. But virtual(More)
Even though the emergence or respectively the construction of online communities is of great interest for scientists and community engineers, only few empirical data has been presented on community growth. This article starts with a reflection on possible growth curves of virtual communities. It contrasts a network externality perspective that produces(More)
In this paper we propose a definition for a mobile community based on the value of knowledge exchange among locally dispersed community members. Against this conceptual background, we propose a low-tech mobile community setting using SMS messaging and customary mobile phones. The feasibility of this approach is tested in a field study. Results show that(More)
Based on an information systems metaphor for virtual communities this paper discusses up-todateness as one crucial factor of travel information quality. Two empirical studies are presented which show that the up-to-dateness of information in travelbooks, wikis and in forum communities does not differ systematically. Based on this empirical evidence we focus(More)
Assessing a considerable lack of systematic empirical evaluation in the field of Knowlegde Management, we give an overview of evaluative approaches in different research areas up to now. We are especially covering those areas which are relevant for the development of Organizational Memories Informations Systems (OMIS): Knowledge Engineering (including(More)
