CuriousU Search Engine Technology will explore the world of search engines. You will learn how search engines work, what challenges they deal with, and how their performance can be measured. And even beter: you will be guided in building, evaluating, and improving your own search engine on a real-world dataset.

To be presented at CuriousU Summer School 2017 13 – 22 August, 2017 at the University of Twente.

Education is changing rapidly. Many universities start to provide their courses on-line, free for everyone to take. To keep up with these developments, I made a short do-it-yourself (DIY) video lecture — appropriately discussing online education — which combines 4 techniques: 1) an ordinary lecture with slides, as always; 2) my talking head from the webcam; 3) written notes on the slides, “Khan Academy-style”; 4) a screencast, capturing live actions on the screen.

In case you like to do this too: The video was made using recordMyDesktop, CamDesk, Xournal, and edited with OpenShot, all running on Ubuntu. I used a webcam to record myself, and a pen tablet (Wacom Bamboo) to annotate the slides. As can be seen, the result is not great: The number of frames per second is low (default is 15 frames per second in recordMyDesktop), the audio quality is low (I need a better microphone), and audio and video are slightly off (not sure why this happened). On Windows a combination of CamStudio, Powerpoint, and Movie Maker might do better.

Many thanks to the following people that advised me or otherwise supported me in making the test online lecture: Wanno Drijfhout & Marije de Heus (Course Managing Big Data), Theo Huibers & Eelco Eerenberg (Thaesis), Tonnie Tibben (Twente iTunes U), Alfred de Vries (SmartXP lab), Peter de Boer & Roy Juninck (FB lecture halls and digital whiteboards). Additional advise and comments are very much appreciated.

This demonstrator showcases the PuppyIR framework by incorporating numerous child specific components developed as part of the PuppyIR project. The Demonstrator is for Emma’s Children's Hospital in Amsterdam and provides children with a novel and exciting interface to help support their information needs while in hospital or visiting the hospital.

EmSe will be demonstrated at the 34th European Conference on Information Retrieval (ECIR) in Barcelona on 1-5 April 2012

Today on Radio 1: An interview by Deborah Blekkenhorst on our attempts to search the deep web. And… no, the deep web is not the part of the web where terrorists hang out. (in Dutch)
