QUIS: Query Heterogeneous Data In-Situ


Data of interest are often found in a variety of data sources, many of which are not relational databases, but have their own data organization and query capabilities. To answer questions of interest, one has to run queries across data from these heterogeneous sources. The traditional approach is to perform multiple individual data transformation tasks, one per data source, to import the data into a common repository where they can be queried and analyzed. Drawbacks of this approach include the manual effort and the cost of transforming and importing potentially large data sets, and the lost opportunity to exploit any query facilities provided by the data sources. QUIS (QUery In-Situ) proposes an approach for querying the data "in-situ" to the greatest extent possible, by taking the user query and transforming appropriate portions of it into corresponding query expressions on individual data sources. Realizing this approach requires the development of a unified query model. This model can extract sub-queries matching heterogeneous capabilities of individual sources, perform heterogeneous joins on intermediate results as necessary, and deal with barriers such as incompatible type systems en route. Early experiments have shown that QUIS almost eliminates the time to prepare the data while paying only a small cost in query execution time compared to a fully integrated, indexed, and loaded relational database.

Adaptive Semantic Assistants in Online Applications


The rapid growth rate of available textual documents underlines a prominent need for novel approaches to overcome the information overload that knowledge workers are faced with. In such situations, new information filtering and analysis techniques are required to provide end users with information related to their context and task at hand. In cooperation with the Semantic Software Lab at Concordia University in Montréal, Canada (, we have been developing a new generation of portals that automatically adapt to their users context using novel techniques from the Natural Language Processing (NLP) and Semantic Computing domains. The vision is to extend an…




The CoSRe project of the Friedrich-Schiller-University of Jena investigates how computers can support the entire scientific life cycle. Today in each science computers are needed, not only for the storage of experimental data, but also for generating simulation data and futhermore for the analysis of different kinds of data. Over the internet scientists can work together and can share their results. This collaboration leads to new knowledge and new challenges. To deal with this "flood of information" the complete scientific cycle has to be supported by computers. For more information about CoSRe - please visit the project website


DIANE - Services in ad hoc Networks


In the DIANE project, we aim at developing and evaluating concepts that will allow integrated, efficient and effective usage of services offered in open and dynamic environments like ad-hoc networks. To achieve these goals, we propose mechanisms to address a number of questions: How can service search be facilitated in decentralized, dynamic environments? How can services be described, automatically found, and selected? How can services be efficiently executed? How can fairness be ensured in open environments? We propose mechanisms to describe, find and select services as well as methods including overlays and replication mechanisms to efficiently process such queries. Additionally,…

OPOSSum (Online POrtal for Semantic Services ) is a portal dedicated to collaboratively build a public test collection of semantic web services. Despite significant research efforts in the field of semantic web services, real tools and applications using them are still rare. One of the main obstacles for improvements in this direction is the lack of sufficiently large and high-quality collections to test and evaluate tools and algorithms for semantic web services. Such collections cannot be built by any single group but only in a collaborative way by the community as a whole. The purpose of OPOSSum is to equip…

Power to the People: Business Users Drive Application Development for Portal Websites


Portals are the next generation application systems, offering personalized, seamless integration of diverse applications. The vision is that in the future, business users without programming expertise will build their own portal based environments. The Heinz-Nixdorf Endowed Chair at the University of Jena plans to extend its current research activities in these directions. This could be well done on the basis of former work and the group's experience in areas like portal technology (gained within the context of JSR 286) and (semantic) web services.


Semantic User Modeling for the Recommendation of Scientific Data


Collaboration with the  Semantic Software Lab, Concordia University, Montréal, Canada Researchers in the medical and life sciences are faced with an increasing abundance of data in scientific repositories. Thus, handling and filtering of data becomes a more and more time-consuming and challenging task. Semantic recommender systems are a new rising research area using underlying knowledge bases, e.g., ontologies in the recommendation process. That allows to present relevant results that go beyond a user’s stored preferences and to include other semantic related terms that are not explicitly mentioned in the user profile. One obstacle for semantic recommendation is the poor description of personalization settings in state-of-the-art user model ontologies. Apart from storing general user interests it is not possible to specify further needs. We aim at the establishment of a formal semantic user model for scientific research objects and its integration and usage in semantic recommender systems.




For the security forces and rescue workers engaged in a major operation, no integrative information and communication tool is available up until now. Today such coordination is carried out by personal consultation at the site, via official radio channels or by means of paper-based documentation. In the case of scenarios such as mass casualty incidents, however, personal consultations or the procurement and dispatch of documents are virtually impossible to manage. Processes are inefficient and precious time is lost as a result: factors that, in the worst case, raise the number of victims. In this BMBF-funded project, this problem is tackled…
