| About Exercise4: I actually dont know how to to write down (but i think i know how/why it works) the prove of top-k retrieval with the maximum-score. Is it okay to describe it in words or do we have to formalize it in a certain way? '''Mirko 5Nov09 22:21pm''' | |

| '''Note about Exercise 5:''' One can assume that a more general model of the word frequencies is given than that given in the lecture, i.e. eps * N * (1 / i^alpha). Now both parameters (eps and alpha) can be estimated simultaneously. '''Marjan 23Oct09 3:29pm''' | Ok, I have played around a bit with lecturnity myself, and published Lecture 3, see the link above.

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.
Here are the recordings of some of the lectures so far (Lecture 1 still missing, in Lecture 2 the microphone signal did not come through): Lecture 3
Here are PDFs of the exercise sheets so far: Exercise Sheet 1, Exercise Sheet 2, Exercise Sheet 3.
Here are your solutions and comments on the previous exercise sheets: Exercise Sheet 1, Exercise Sheet 2.
Here are the rules for the exercises as explained in Lecture 2.
Exercise Sheet 3
By popular request, I have already uploaded a tentative version of the next exercise sheet; see above. It may still change (that's what the word tentative means), but probably not much. I will also try to upload a tentative version of my slides for the next lecture later tonight. Several people have asked for this, since they felt they had too little time for the exercises (Thursday - Tuesday) otherwise. By posting a tentative version of the exercise sheet (and possibly also of the slides) two days earlier, you can at least start to think about the exercises. Say that I'm nice!
BTW, the next lecture will be about "everything you always wanted to know about ranking".
Here you can upload your solutions for Exercise Sheet 3.
