In order to allow safe operation and good performance, robots need an accurate model of their environment. Such a world model is constructed from sensor detections and typically contains information about positions and velocities of surrounding objects. This paper proposes how prior knowledge about those objects can be used to improve the performance of a world model, which is implemented by a ...

We present the idea of an approach to database query sharding that makes use of knowledge about data structure and purpose. It is based on a case study for a database system that contains information about documents. By making use of knowledge about the data structure and the specific top-k queries to be processed we demonstrate a method for avoiding costly and unnecessary steps in query answer...

While the Web of data is attracting increasing interest and rapidly growing in size, the major support of information on the surface Web are still multimedia documents. Semantic annotation of texts is one of the main processes that are intended to facilitate meaning-based information exchange between computational agents. However, such annotation faces several challenges such as the heterogenei...

Migration of legacy assets to SOA embodies a key software engineering challenge namely rehabilitation of pre-existing enterprise assets into service based systems. Existing service analysis and design methods mostly focus on development of new services while they lack in transforming services from already existing enterprise assets. We argue that, a comprehensive SOA migration methodology is es...
