Pascal Francq earned his Master's degree in applied science and his Phd thesis at the Université Libre de Bruxelles (ULB). From 2003 until 2008, he held the chair in information systems and in digital information at the ULB. He decided to quit due to the lack of time and resources for his research activities. He is currently financed by a project of the Walloon Region at the Université Catholique de Louvain (UCL). In 2010, he founded the Paul Otlet Institute to continue his research and teaching projects. He is the current president of the insitute.
His research topics are centred around the Internet: its technologies, its societal aspects and its support as a platform for knowledge sharing. He published a book on the Internet object: its histories, its myths, the practices it allows et its issues. Since 1998, he worked on automatic detection of communities of interests, and is the main contributor of the GALILEI platform. It also supplies WikiCS. He is currently working on the XML corpus clustering as well as the expertise detection in document corpus (such as emails).
Pascal Francq has particularly specialized in optimization techniques based on genetic algorithms, which he adapted the principles to several problems.
Pascal Francq is the maintainer and the main contributor of the R and GALILEI projects.
Scientifically, he developed :
- A tensor space model to describe objects (such as documents or user profiles) in conceptual space (which dimensions correspond to the different concepts).
- A similarity measure between two objects (for example two documents) by taking into account different categories of concepts (content, metadata and structure).
- An adaptation of the “user relevance feedback” methods to compute user interests.
- Two adaptations of Grouping Genetic Algorithms (GGA) for object clustering when a similarity measure exists : the Similarity-based Grouping Genetic Algorithm (SGGA) and the Nearest Neighbors Grouping Genetic Algorithm (NNGGA).
- The Hierarchical Generic Algorithms (HGA), a genetic algorithmtaht builds a hierarchy of objets, each objet being represented by a liste of attributes. The HGA was applied for the semi-automatic construction of a thesaurus.
- The 2D Genetic Algorithms (2D-GA), a kind of genetic algorithms to place a series of objects on a given surface. The 2D-GA was applied during a research project dedicated to the placement of electronic components on a silicon chip.
