Now, that everyone has submitted their reports on Project B, we publish the results of SRL competition (or shared task, if you like). We have 12 student scores (3 persons did not want their results to be shown), and one baseline system score. The gold test set is published as well, together with the evaluation script.

5 submissions were made after the first official deadline, they are marked 'late'.

The submissions were evaluated with 4 metrics:

1. Macro F1 measure
2. Accuracy
3. Correlation between the frequencies of each role in...

I have uploaded earlier exams, see here.

The regular lectures and lab sessions are finished. Because of the very late exam, we will postpone the wrap-up and exam exercise session(s) to the week starting 11 Dec. We will meet Monday, 11 Dec, and - if demanded - Tuesday 12 Dec.

Here are some additional remarks to the obligatory assignment 4 (Project B):

1. In some classifiers, categorical features with high cardinality (like lemmas for predicates/arguments) can greatly increase the training time after being converted to sparse binary vectors. Thus, it is not obligatory to use lemma of the predicate (the first feature from section 2.2 of the assignment) in your baseline system. However, you can decide to somehow cope with the sparsity problem or use other classifiers, if you want.
2. The global scoring part (section 2.4 of the assignment) is an advanced-level task (*). It is possible to get a passing grade without fully completing this part. Still, you should at least try after you are done with other parts....

Obligatory assignment 4 on semantic role labeling (Project B) is published now. Good luck with it!

Example solutions for the obligatory assignment 3  (Project A) are published on the UiO Github.

Also, the reading list for the lecture 13 "Modern Approaches to Semantic Role Labeling" (November 14) is available on the Syllabus page.

The reading list for the lecture 11 "Word Sense Disambiguation today" (October 31) is available on the Syllabus page.

Obligatory assignment 3  on dependency parsing (Project A) is published now. Good luck with it!

The reading list for the lecture 7 "Modern Approaches to Dependency Parsing" (October 3) is available on the Syllabus page.

I have given individual comments in devilry and put a sketch of a solution in /projects/nlp/inf5830 at the IFI cluster.

I have got some questions regarding oblig.2, and have posted some answers here.

The reading list for the lecture 6 "Dependency grammar and data-driven dependency parsing" (September 26) is available on the Syllabus page.

The second obligatory assignment is out.  Deadline is 6 October. Enjoy!

There will be regular lab session, Monday 18 Sept. at 1215.  And there will be regular lecture Tuesday 19 Sept at 1015. No (more) Monday tutorials.

The next main lecture (lecture 4) has been moved from Tuesday, 12 Sep. to Monday 11 Sept., 1415 in Perl. (The regular tutorial slot after the lab session). No class Tue 12 Sept. See syllabus page for program.

The first obligatory assignment is out. Due date 22 Sept. Also dates for forthcoming assignments is out.

I have made a query regarding your background knowledge. It is anonymous. Please go to https://nettskjema.no/a/86391 and answer the query.

Welcome to a new semester. First class is Tuesday 22 August. I have posted some more information, in particular on expected background. Look at the syllabus link.
