Queries in context: Access to digitized historic documents in a collaboratory for the humanities

2005 , Thiel, U. , Brocks, H. , Dirsch-Weigand, A. , Everts, A. , Frommholz, I. , Stein, A.

In contrast to standard digital libraries, systems addressing the specific requirements of cultural heritage need to deal with digitized material like scanned documents instead of home digital items. Such systems aim at providing the means for domain experts, e.g. historians, to collaboratively work with the given material. To support their work, automatic indexing mechanisms for both textual and pictorial digitized documents need to be combined with retrieval methods exploiting the content as well as the context of information items for precise searches. In the COLLATE project we devised several access methods using textual contents, feature extraction from images, metadata, and annotations provided by the users.

The extended process model - transforming process specifications into ontological representations

2006 , Brocks, H. , Meyer, H. , Kamps, T. , Begger, C.

Knowledge-intensive processes arc often open ended and can be only weakly specified in traditional business process models. The extended process model provides a comprehensive integration of process and knowledge specific aspects within a single, ontological representation. In this article we describe the transformation of standardized business process definitions into a unified conceptual process model. We then apply our methodology to the scenario of IT services.

A multiagent environment for the flexible enactment of knowledge-intensive processes

2006 , Bayer, K. , Kempf, S. , Brocks, H. , Kamps, T.

Knowledge-intensive processes are characterized by vague specifications and a dynamic course of action. They require a flexible, knowledge-based enactment environment supporting the dynamic allocation of resources, changes in assignments, organizational structure, policies, and requirement and priorities, but also conflicts between resources participating in different processes. In this article, we present a multiagent enactment environment that incorporates the flexible allocation of resources but is also capable of handling various types of runtime exceptions. The benefits of adopting a knowledge-based approach are demonstrated based on a prototype implementation of an IT-Helpdesk scenario.

Flexible exception handling in a multi-agent enactment model for knowledge-intensive processes

2005 , Brocks, H. , Meyer, H. , Kamps, T. , Begger, C.

Exceptions in knowledge-intensive processes are often the result of resource failures. Following a knowledge-based approach we demonstrate how semantic information about the resources involved and a set of generic Event-Condition-Action rules are used to handle resource-related exceptions within a multi-agent enactment environment. The scenario of an IT-Helpdesk is used to illustrate the application of the concepts described within a practical environment.
