Dutch-sponsored researcher Krisztian Balog has developed a computer program that speeds up the process of finding the right person in an organisation’s network. This technique can also make it easier to search for specific people on the Internet.
An increasing amount of information is available nowadays via the Internet. Yet can all this information be found? Search engines are already effective in searching for documents, yet are far less good at searching for entities, such as persons. Krisztian Balog introduces two new models in his thesis that make finding the right person quicker and more accurate.
Balog specifically focuses on searching and finding people within companies and organisations. In the business world in particular, an effective search system can be very useful. For example, it could enable a manager to quickly find out who had previously worked on a certain project without having to plough through a pile of paperwork.
Such a search system is not only useful within companies but can also ensure a better exchange of information between companies and the press or between companies and employment agencies. For example, an HRM department can use the search system to find out more about job applicants.Finding and profiling
The problem of searching for people is that a person is not a collection of words. Text, however, is. When you search for a text you submit a number of words and then find texts that contain these. Such a search query is relatively uncomplicated. A person cannot be found in the same manner. However, a person does leave a digital trail because his or her name can be found in the texts. Balog's program automatically links the information in these texts to a person. Balog developed a method that uses these digital traces to compile a list of subjects for a person. The program accordingly selects the person that can satisfy the criteria of the search query.
Balog combines so-called generative language models with learning algorithms. The language models expose patterns in the language use with respect to persons and subjects. Learning algorithms recognise people and organisations in texts. Balog's methods have been extensively tested, for example on the intranet of large organisations with people at different locations, such as W3C and CSIRO. The method has also been tested on the intranet of a Dutch university.Widely usable
Krisztian Balog was a PhD student in the research group of Maarten de Rijke. De Rijke received a Pioneer subsidy from NWO in 2001 and used this to set up the project 'Computing with Meaning'. Between 1989 and 2002 more than 100 highly experienced researchers who had the potential to become full professors received a Pioneer subsidy. This is comparable to the current Vici subidy from NWO. The research group hit the headlines earlier with MoodViews, a program for tracking and analysing moods of bloggers on the Internet (see press release 4 April 2006, http://www.nwo.nl/nwohome.nsf/pages/nwoa_6njj78). Balog was the last PhD student under Maarten de Rijke's Pioneer project.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
