The former approach to grammatical analysis is often called formal, while the latter approach is normally called functional.

What is LFG in NLP?

Lexical Functional Grammar (LFG) plays a vital role in the area of Natural Language Processing (NLP). LFG is considered as the constraint-based philosophy of grammar. C-structure and F-structure are the two basic forms of LFG. Arabic language along with its parsing techniques is demonstrated.
