Welcome to the Wiki page of the course Search Engines, WS 2009 / 2010. Lecturer: Hannah Bast. Tutorials: Marjan Celikik. Course web page: click here.

Here are PDFs of the slides of the lectures so far: Lecture 1, Lecture 2, Lecture 3, Lecture 4, Lecture 5, Lecture 6, Lecture 7.

Here are .lpd files of the recordings of the lectures so far (except Lecture 2, where we had problems with the microphone): Recording Lecture 1, Recording Lecture 3, Recording Lecture 4, Recording Lecture 5 (no audio), Recording Lecture 6 (with audio for a change), Recording Lecture 7 (AVI).

Here are PDFs of the exercise sheets so far: Exercise Sheet 1, Exercise Sheet 2, Exercise Sheet 3, Exercise Sheet 4, Exercise Sheet 5, Exercise Sheet 6, Exercise Sheet 7.

Here are your solutions and comments on the previous exercise sheets: Solutions and Comments 1, Solutions and Comments 2, Solutions and Comments 3, Solutions and Comments 4, Solutions and Comments 5, Solutions and Comments 6.

Exercise Sheet 6

The recordings of all lectures are now available, see above. Lecture 2 is missing because we had technical problems there. To play the Lecturnity recordings (.lpd files) you need the Lecturnity Player, which you can download here. I put the Camtasia recordings as .avi files, which you can play with any ordinary video player; I would recommend VLC.

Here are the rules for the exercises as explained in Lecture 2.

Here you can upload your solutions for Exercise Sheet 7.

@whom it may concern: for me the access-rights stuff did not work exactly as in the lecture - i had to move the whole site (.html .js ...) into the server directory. Maybe it's new to firefox 3.5 but i could not access any file on the server from a .js not being in the server directory - it always turned my GET-Requests into OPTIONS-Requests and nothing was returned - so the php-solution does not seem to work, even if my server was able to execute php. Were we supposed to do it like this anyway or is it completely wrong this way?.. alex 5Dec09 17:56

Ok, the recording of Lecture 7 is now available as AVI. But beware, it's quite big: around 300 MB. Hannah 3Dec09 22:46

To play the .camrec recording you need the full Camtasia Studio (you can download a 30-day test version if you want). I will soon upload an .avi version instead. Hannah 3Dec09 21:56

For your reference and convenience, here is a tar archive of the files which we wrote together in Lecture 7 (prefix-search.html, prefix-search.css, prefix-search.js, prefix-search.php). Hannah 3Dec09 21:35
