As long as there is not a sufficient base of RDF-annotated pages, the benefits of participating in the SemanticWeb are barely visible. This is true in particular for content providers like individuals or small institutions. These potential participants can’t afford the additional work necessary for the Semantic Web, yet they’re needed for the Semantic Web(More)
Although a promising idea, the Semantic Web currently seems to have a problem duplicating the success story of its predecessor, the World Wide Web. The number of people actively participating in the Semantic Web has been very limited until now, because people can't see the bene ts originating from the extra e ort they invest into semantically rich web(More)
A large part of software development these days deals with building so-called Web applications. Many of these applications are data-base-powered and exhibit a page layout and navigational structure that is close to the class structure of the entities being managed by the system. Also, there is often only limited application-specific business logic. This(More)
Although RDF is considered the Semantic Web language, it may not be the only one. SOAP serialisation provides several advantages, especially if the Semantic Web is not just about providing meta data for existing web pages, but also about exchange of content that is machine-readable in the rst place. This paper discusses some problems with the RDF syntax and(More)
For biological agents, the perceived world does not consist of other agents only. Also software agents can have a shared world model they operate on. In this paper we discuss information systems as an important part of software agents' environment and try to identify the corresponding demands, leading us to build an information system for software agents on(More)
Ontologies are important for providing a shared understanding of a domain for web mining agents and other agents accessing the gathered information. When the information access is decoupled from the mining process – for example when building a semantic web server – an additional storage compliant to the application ontology is needed. The COMRIS information(More)
Currently, many kinds of information agents for di erent purposes exist. However, agents from di erent systems are still unable to cooperate, even if they accurately follow a common standard like FIPA, KIF or KQML. Being able to plug agents together with little e ort and exchange information easily, would be of a great use for several reasons. Among others,(More)
In spite of the growing number of KMS emanating from academia, only few of these systems seem to be actively used by their creators. We can only speculate about the reasons, but a lack of usability and support for real-life business processes is likely to be one of them. This paper presents the Infolayer, a KMS developed at the Artificial Intelligence unit(More)
The COMRIS project (Co-Inhabited Mixed Reality Information Spaces) is intended to build a conference system supporting participants by personal software agents. The agents perform several tasks like commitment reminders or negotiations with other personal agents about meetings. A hardware device worn by the user enables the agent to speak to him through an(More)
