We discuss our DLDB knowledge base system and evaluate its capability in processing a very large set of real-world Semantic Web data. Using DLDB, we have constructed the Hawkeye knowledge base, in which we have loaded more than 166 million facts from a diverse set of real-world data sources. We use this knowledge base to demonstrate realistic integration queries in egovernment and academic scen...

Research on robot Learning from Demonstration has seen significant growth in recent years, but the field has had only limited evaluation of existing algorithms with respect to algorithm usability by naïve users. In this article we present findings from a user study in which we asked non-expert users to use and evaluate three different robot Learning from Demonstration algorithms. The three algo...

Distributed geospatial data and services can be used to form Spatial Data Infrastructures (SDI). Current technological developments enable SDI to process large amounts of geospatial data. In this context, Web Processing Services (WPS) can be used as an open interface standard for accessing and executing geospatial processes. Since many SDI are based on Service-Oriented Architectures (SOA), the ...

This paper describes Familiar, a domain-independent programming by demonstration system for automating iterative tasks in existing, unmodified applications on a popular commercial platform. Familiar is domainindependent in an immediate and practical sense: it requires no domain knowledge from the developer and works immediately with new applications as soon as they are installed. Based on the A...

An innovative task learning system called PLOW (Procedure Learning On the Web) lets end-users teach procedural tasks to automate their various web activities. Deep natural understanding and mixed-initiative interaction in PLOW makes the teaching process very natural and intuitive while producing efficient/workable procedures.
