In engineering projects, like building a highway, several interest groups must be involved and the aim is to achieve a good consensus between the varies interest groups and get a feasible solution. This consensus process is based on discussing various design alternatives often sketched in a spatial representation (e.g. a map). During this process several alternatives are discussed, modified, rejected and adjusted over time. To keep the spatial representation readable, separate temporal tendencies requires to aggregate contributions provided by the interest groups according to topic, space and time dimension.
In this PhD project a framework will be developed to access tagged information in a temporal spatial environment on varying aggregation levels to enable the zooming in and out of a map. The challenge is that not much is known on which content will be available, on how the discussion will evolve and which scale the discussion will be performed. Further, the amount of information will make it necessary to pre-process the information to enable fast, web based access. Thus, the main challenge is to provide information in a fast and flexible way without making many assumptions on the information provided by the users and the way users are going to query this information. In this project the idea is to observe the query behaviour of users and self-organize the pre-aggregation levels. I.e., based on the observed user behaviour and a storage boundary the optimal pre-aggregation levels are determined in a streaming fashion minimizing the query response time.
The Database Group of the University of Twente offers a PhD position in the Dutch national project COMMIT, a 100M Euro project involving 10 universities and 70 companies. The program brings together leading researchers in search engines, parallel computing, databases, interaction in context, embedded systems and knowledge technology.
We offer a full-time PhD position in a dynamic and international environment. The duration of the contracts is four years. The gross salary will range from € 2.042,00 in the first year to € 2.612,00 per month in the fourth year.
Additionally, the University of Twente provides excellent facilities for professional and personal development. In addition, we offer a holiday allowance (amounts to 8%) and an end-of-year bonus of 8.3% (which is approximately an extra month of salary) and a number of additional benefits. The labor agreements are in accordance with the CAO-NU for Dutch universities.
We are looking for a candidate with a MSc. degree in computer science, databases, software engineering, information systems, mathematics (with a computer science specialization), or an equivalent degree. The work involves both theory and practice (implementing a research prototype and evaluation in an application context). The candidate must provide good communication skills, in writing as well as oral. Your main task will be to do research, but you will be given opportunities to acquire some teaching experience.

The University of Twente. We stand for life sciences and technology. High tech and human touch. Education and research that matter. New technology which drives change, innovation and progress in society. The University of Twente is the only campus university in the Netherlands; divided over six faculties we provide more than fifty educational programmes. The University of Twente has a strong focus on personal development and talented researchers are given scope for carrying out pioneering research.
In the Faculty of Electrical Engineering, Mathematics and Computer Science (EWI) is the place where these three disciplines shape Information and Communication Technology at the University of Twente. ICT is more than communication. In almost every product we use mathematics, electronics and computer technology are present, and ICT now contributes to all of societies’ activities. It is no longer about gadgets that we do or do not want to use. The real integration of ICT is just beginning. What we need is more intelligence in our systems and improvement of their natural interaction with humans.
