In data compression and the theory of formal languages, the smallest grammar problem is the problem of finding the smallest context-free grammar that generates a given string of characters (but no other string). The size of a grammar is defined by some authors as the number of symbols on the right side of the production rules.Others also add the number of rules to that. The (decision version of the) problem is NP-complete.The smallest context-free grammar that generates a given string is always a straight-line grammar without useless rules. (Wikipedia).

SYN110 - Variants of Generative Grammar I
There are several problems for simple phrase structure grammars (PSG). In this first E-Lecture of a series of related videos, Prof. Handke discusses these problems and points out where and what adjustments have to be made to expand a simple PSG into a more elaborate version of a generative

Computational Linguistics 1: Dependency Parsing
There is an error in the slides: The complexity of Eisner's algorithm in O(n^3). The slides incorrectly state that the chart is of size O(n); the chart is actually of size O(n^2). Because there is a linear search over subspans, the total complexity is O(n^3) (as stated in the slides).
