Being able to recognise and make use of such patterns is lucrative business for companies. Edgar de Graaf discovered that interesting patterns often contain a time aspect. Jeroen De Knijf developed methods to detect relevant patterns quicker.
In subject jargon it is called data mining: looking for interesting relationships within large quantities of data. Many data-mining programs produce a flood of potentially interesting patterns: as a user, how can you then find what you are looking for? Furthermore, the files are not always set up for such search actions, as is the case on the Internet or for instance in bioinformatics. It usually concerns semi-structured files: they often contain, for example, hyperlinks to other files, and contain (partial) information in a range of formats, such as text, images and sound.MISTA project
The patterns can best be presented visually so that the user can find the information sought at a single glance. To realise this De Graaf described various ways of presenting different types of information.Wikipedia compressed
A second method De Knijf devised to reduce the number of results is the compression of the entire collection of documents (for example, Wikipedia pages) into a single document. By building accurate models that only make use of the compressed document, De Knijf was able to demonstrate that this summary does indeed contain the essential information from the entire collection.
The research was funded from the Open Competition 2003 of NWO Physical Sciences.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
