Search Engines and Information Retrieval Systems, ir12
A course in Computer Science focusing on basic theory, models, and methods for information retrieval.
If you took DD2475 ir10, and have lab assignments and/or the project left, you are very welcome to finish these during the spring of 2012. Please contact Hedvig Kjellström (see People in the meny) to let us know that you are following the course.
June 21: The course analysis can now be found under Course Analysis in the menu. Have a great summer everyone!
June 06: Thank you for an inspiring course, especially the fabulous poster presentations! The project grades are now reported. You can retrieve the commented reports in paper form at the CSC student expedition, Osquars Backe 2, bottom floor, starting Monday.
April 25: Announcements in connection to today's guest lectures: SU DSV announces 1-3 PhD positions, deadline April 30. For more info, contact Hercules Dalianis.
April 25: The computer hall session May 9 has been cancelled, due to schedule clashes for Hedvig and Johan. If you have questions about the projects, which can not be answered by the project proposers, contact Hedvig or Johan via email.
April 2: The poster session has been moved to May 16, 10:00-12:00, to enable Johan to be there. The schedule is updated with that information. Since the attendance is compulsory for everyone, I would like to know asap if you can not attend (due to any other compulsory activities). Send me an email in that case, describing why you can not attend.
April 2: The exams are now corrected and can be collected at the CSC student expedition beginning tomorrow morning. The results (6 A, 11 B, 3 C, 3 D, 1 E, 4 Fx, 0 F) are reported into Rapp. Passed exam results will appear in Ladok in a few days, and students that got Fx will be notified via email, with further instructions on how to complete to E.
March 20: The projects are now listed under Project in the menu. The first thing to do is to form project groups of 4-5 students. We will do match-making in the break on Wednesday, for those of you who have not formed groups yet.
February 27: No registration needed for the exam, just show up!
February 27: If you have an assigment left to present, please make an appointment with Hedvig or Johan as soon as possible, to be sure to be able to present it before the exam. (The assigments need to be examined before you are allowed to take the exam.)
February 26: In order to prepare for the exam, please have a look at Written Exam in the menu, where the grading, content and form of the exam are explained. You can have a look at last year's exam to get an idea of what it will look like. We also recommend that you do the exercises of Chapters 1-9, 11, 12, and 21.
February 24: The projects will be announced within the next week. They will probably be performed in groups of 4-5 students - which means that there will be 6-7 project groups. Groups will be formed in the beginning of period 4. In addition to the suggested topics it is also possible to suggest your own. If you have an idea of your own project, please send an email to Hedvig or Johan!
February 14: You can now book a time slot for presenting your solutions to Computer Assignment 2, using this Doodle. The presentation takes place in front of a computer in Spelhallen on February 24. All members of the group have to be present, and be prepared to answer questions on all parts of the assignment.
January 30: We have rearranged the order of lectures 3-5, to give you the theory for Assignment 2 earlier - tomorrow, we will go through ranked retrieval. Sorry about the late notice! (The reason for the old order of lectures was that index compression was a part of assignment 1 last year, and had to be covered as early as possible in the lecture series.)
January 27: There was a bug in the
January 24: You can now book a time slot for presenting your solutions to Computer Assignment 1, using this Doodle. The presentation takes place in front of a computer in Sporthallen on January 31. All members of the group have to be present, and be prepared to answer questions on all parts of the assignment.
October 21: The homepages are now up and running. The course has changed names (and course code from DD2475 to DD2476), but cover essentially the same content, with a slight shift in focus towards web search, with e.g. a deeper coverage of linked document retrieval.
After completing the course you will be able to:
Basic and advanced techniques for information systems: information extraction; efficient text indexing; indexing of non-text data; Boolean and vector space retrieval models; evaluation and interface issues; structure of Web search engines.
Other ResourcesTo get an idea of state-of-the-art in Information Retrieval research and development, take a look at the program of the annual conference ACM SIGIR.
AssignmentsThe examination in the course is performed through:
GradingCourse grades are assigned according to the following (CA = computer assignment grade, WE = written exam grade, PA = project assignmnent grade):
If CA = F, WE = F or PA = F, that part of the course has to be re-examined, until CA = P, WE >= E and PA >= E. The course grade is the average of WE and PA, according to the following:
