Making the vision of a reliable Web of Data become a reality

What is your project about?

The World Wide Web is one of the most influential inventions that have radically changed our lives. One part of it, however, is designed for machines and provides access to vast amounts of data: the Web of Data – a building block of the Semantic Web. Although the information on the Web of Data is freely available and covers a broad range of topics (general knowledge, life sciences, geography, government, etc.), it remains mostly unexploited. One of the main reasons for this unused potential is the unreliability of the service in terms of availability, quality, and transparency. The goal of this project therefore is to develop breakthrough technologies that overcome these problems and establish a reliable Web of Data whose information can be queried reliably and in doing so enable novel applications and use cases.

How did you become interested in your particular field of research?

The vision of the Semantic Web and the Web of Data is to enable intelligent machines that can automatically find, process, and understand information on the Web. In a sense this is similar to intelligent personal assistants but instead of being bound to a particular company or service provider based on publicly available data and standards. I have always found this vision very intriguing and am happy to contribute to advancing the state of the art and making this vision become a reality.

What are the scientific challenges and perspectives in your project?

State-of-the-art approaches for processing queries on the Web of Data rely on the assumption that data and querying services are always reliable. However, this is simply not the case: if certain data is, for instance, temporarily not available, the same query can have different results at different points in time. One of the project’s key challenges therefore is to develop techniques that effectuate a paradigm shift on how information on the Web of Data is accessed, managed, and processed. Achieving this goal will boost the wide acceptance and success of the Semantic Web in general. 

What is your estimate of the impact, which your project may have to society in the long term?

A reliable Web of Data will enable a broad range of novel applications and use cases. Just as personal assistants are becoming more important aspects of our everyday lives, novel applications tapping into the huge amount of Open Data that a reliable Web of Data provides access to have a similar potential. By enabling intelligent machines to automatically find, process, and understand information, we for instance facilitate computational journalism and fact checking for which a reliable Web of Data in terms of quality, transparency, and availability is of utmost importance. Furthermore, by lowering the burden of data providers in terms of maintenance, required expertise, and technical resources, many more datasets will be made available, which in turn helps the Web of Data grow and inspire even more applications. 

Which impact do you expect the Sapere Aude programme will have on your career as a researcher?

The Sapere Aude project strengthens innovation and growth in my field of research. It enables me to build a strong and innovative team and facilitate collaboration with national and international institutions in both academia and industry. This gives me the unique opportunity to establish a strong research group and competence center on Semantic Web research.

Background and personal life

I am living together with my husband and our two small children (1 and 3 years old) in Aalborg. In my free time, apart from spending time with my family, I am enjoying reading, meeting friends, and going to the cinema.
