Closed Projects

• Incomplete Workflows

• Advanced Database Technologies in Bioinformatics

• DirX-Server query optimization

• Conceptual Modeling of XML data schemata

• DESWAP (Development Environment for Semantic Web APplications)
The project KnowledgeNets analyzes potential impacts of Semantic Web technologies on the electronic markets and the business specific value chains. Thus e-commerce scenarios are developed in which the new technologies are applied to various application domains. Afterwards these future scenarios are subject to experiments and analyzes.

• DirX-Extend
Tools and Concepts for extending Siemens' DirX LDAP-Server

• Practical Private Information Retrieval (2PIR)

• Query Processing

• Privacy and Security

• The Query Web
We develop a novel architecture for query processing which we term “The Query Web” to address these challenges within a dynamic scenario where nodes regularly join and leave the network. By combining a distributed hash table approach with unstructured P2P networks, we expect the index to be reasonably insensitive to both changes of the network structure as well as updates of the data instances.
