[[SearchEnginesWS0910/Rules|Here are the rules for the exercises as explained in Lecture 2]]. == ABOUT THE MID-TERM (TRIAL) EXAM == Ok, guys, thanks for your votes. '''The winner is Friday, December 18, 16 - 18 h.''' The exam will start at 4.00 pm, so please be there in time. I yet have to find a room, but that shouldn't be a problem at that time of the day and week. I will inform you once I know which week it is. Here are the rules of the exam: 1. It's an open book exam, that is, you can bring and use any amount of books, papers, etc. In particular, printout of the lecture slides, exercise sheets, your solutions, etc. Also any amount of private annotations and the whole CS library if you want. You won't need much for the exam though. I think what will be most useful are the slides, so that you can look up the basic definitions of stuff, in case you forgot them, and your solutions of the exercise sheets. 2. You are not allowed to use any computing devices, mobile phones, etc. In particular, you are not allowed to communicate with others or in any way connect to the Internet or something like that. You won't need a pocket calculator. In case you need to compute log_2(10/7), we will tell you what it is. Things like 2 * 0.5 or log_2(10/5) you should be able to compute by yourself. 3. Expect one or two tasks where you have to write code for some small functions. For example, a binary search in a list of strings. (No, that will not be a task of this exam.) You can use any of the standard languages: Java, C++, C#. Python and PHP are also ok if you absolutely must. Or you can also use pseudo-code. Anyway, you will be asked to write only relatively simple functions, which do not require any involved language-specific things. You should know basic data structures like arrays, lists, and hash tables though. 4. The material covered is simply everything that we did in the lectures and in the exercises, and nothing beyond that. Note that if you haven't really understood a topic, and then comes a task about that topic, you won't have enough time to go to the slides, understand it, and then solve the task. That is, you should have a basic understanding of everything we did, before the exam. If you did all the exercises, and did the well, chances are high that you have that understanding. 4. In the trial exam there will be 5 tasks of which you have to solve 4. Given that the total time for the exam is 2 hours, this means that you will have 30 minutes for each task on average. We will not be super-strict with the time, that is, if it's 6 pm and you need a little longer that is fine. 3. This is a pure trial exam, which will not influence your final mark in any way. We will correct the exam like the real thing though and give you real marks, so that you get an impression of where you stand. 1. + 2. will most probably also hold true for the final exam. 3. obvisouly not. |

I don't know if this is the right place to ask, but I can't access my exercise page. It says "Sie dürfen diese Seite nicht ansehen." '''Johannes 24Oct09 11:50pm''' Good question, Johannes. Please upload the source code separately, either as a .zip or .tgz archive. I have modified the instructions on the upload page accordingly. Sorry if that means additional work for you, we weren't expecting anybody to submit so early ... '''Hannah 24Oct09 11:43pm''' Shall we put the whole source into the PDF? What about tar.gz? '''Johannes 24Oct09 5:18pm''' Hi Johannes + all, the slides are now availabe as PDF, see the link above. '''Hannah 23Oct09 17:04''' '''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''' Can you provide the slides as PDF? '''Johannes 23Oct09 10:05am''' Please note that the deadline for uploading your solutions of the exercises is always Monday, 23:59 (sharp). '''Marjan 22Oct09 6:15pm''' When you add a question or comment here, please end it with your name and the date and time in bold face, just like I did now. '''Hannah 22Oct09 01:59am''' |
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 .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), Recording Lecture 8 (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, Exercise Sheet 8.
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, Solutions and Comments 7, Solutions and Comments 8.
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.
