Some final notes about marks and grades, in response to questions raised in this and other courses.
Continue reading Exam on Tuesday
I’ve uploaded reports on the written assignment and on last year’s Inf1-DA exam. These give detailed notes on solutions and discuss the range of answers given by students. You can also find these on the coursework web page and the ITO past paper pages.
Please fill out the short online feedback survey for Inf1-DA. This is organised centrally by the University, with all results sent to the individual course organiser and to the Director of Teaching. I read every comment individually, and for Informatics courses we post results online to help other students choosing courses for the future.

The tutorials web page now has the latest set of exercises. As before, Question 1 is based on content of Tuesday’s lecture, and material for Question 2 appears on Friday.
Continue reading Week 10 Tutorial Exercises: Statistical Analysis
In the most recent tutorial exercises you used the
cqp tool to search a 3-gigaword Dickens corpus. We also have the 96-gigaword British National Corpus installed under
cqp which you can explore by selecting
BNC at the commmand line.
$ cqp -e [no corpus]> BNC BNC> AllWords = [word="[a-zA-Z].*"] BNC> size AllWords 96063265 BNC>
This has part-of-speech and lemma information like the Dickens corpus, using the Claws 5 POS tag set. As this corpus is much larger you will find queries take noticeably longer to execute.
I also recommend reading the following article on the design and creation of the BNC.
- Gavin Burnage and Glynis Baguley. The British National Corpus. Library and Information Briefings 65, February 1996.
This includes information about text corpora in general, as well as specific details about how the BNC came about.
The tutorials web page now has the latest set of tutorial exercises. The coursework assignment has also been running for a week now, and is due in on Thursday next week. The Information Retrieval tutorial work is fairly brief, which will allow you to spend time in the tutorial discussing any questions you have about the assignment. Please do take advantage of this: attempt every question in the assignment before your tutorial, and note down any concerns you have.
