Introduction

Welcome to the homepage of Urdu Morphology. We provide an Urdu Morphological Analyzer & Generator which is developed by using Functional Morphology (FM) as a Master thesis under the supervision of Prof. Aarne Ranta at Language Technology group, Department of Computer science, Chalmers University of technology, Sweden. Harald Hammarström was also involved in this project quite extensively to review the work.

We provide following components as a software package which is available to download below uder GNU General Public License:

• An implementation of Urdu morphology as an open source software API having:
  • A type system that covers language abstraction of Urdu completely.
  • An inflection engine that covers word-and-paradigm morphological rules for Urdu with a considerate level of depth for every word class.
  • Rules for automatic lexicon extraction using extract tool.
  • A lexicon of 4163 words and 96840 word forms.
  • A manual for users/lexicographers to add new words into the lexicon
• An implementation of a small part of Urdu syntax in Grammatical Framework by reusing the above mentioned resources
• A Unicode Infrastructure for the Urdu morphology API to accommodate Perso-Arabic script of Urdu including a GUI application and useful tools
