Abstract:
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. We have perceived from the existing literature that LFG has not studied in details; the reason that encouraged us to work on this study. This study highlights the brief history of LFG along with its architecture. Arabic language along with its parsing techniques is demonstrated. Moreover, this study addresses the efforts that LFG played in resolving various NLP issues. New trends have been triggered while conducting this survey and have been demonstrated for pursuing further research.
