Greetings from CuriousU Search Engine Technology

Thursday, May 11th, 2017, posted by Djoerd Hiemstra

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.

Traitor: Associating Concepts using the WWW

Wednesday, April 17th, 2013, posted by Djoerd Hiemstra

by Wanno Drijfhout, Oliver Jundt, and Lesley Wevers

Traitor uses Common Crawl’s 25TB data set of web pages to construct a database of associated concepts using Hadoop. The database can be queried through a web application with two query interfaces. A textual interface allows searching for similarities and differences between multiple concepts using a query language similar to set notation, and a graphical interface allows users to visualize similarity relationships of concepts in a force directed graph.

To be presented at the 13th Dutch-Belgian Information Retrieval Workshop DIR 2013 on 26 April in Delft, The Netherlands

DIY online lecture

Wednesday, January 30th, 2013, posted by Djoerd Hiemstra

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.
