Informatics 2A: Competitive Grammar Writing Exercise



The exercise will take place in Lecture 24, on November 10, 2017. Class that day could potentially take two hours (it is your decision whether to stay for a second hour).

There will be a special hands-on lecture, in which you will design and develop a grammar for English, as part of a Competitive Grammar Writing task. The goal of this exercise is to experiment with the ambiguity that is present in natural language, and understand how complicated it is to model natural language syntax, as opposed to programming languages syntax which you leared about earlier in the class.

Preparation before the lecture:

During the lecture:

Come prepared to the lecture! If you feel comfortable with the exercise, you are more than welcome to work on your grammar at any point before the lecture.

After the lecture:

Evaluation of grammars:

We will evaluate your grammars by doing the following: This means that you want to generate grammatical sentences as much as possible, while making them complex so that other grammars cannot parse them. The team with the best grammar will get a small prize in the lecture on XX November 2017. Depending on the financial situation of the lecturers at the time, there might be second- and third-place prizes. No grade-affecting marking is involved in this assignment.
