![]() ![]() Forms of the verb, as well as case, gender, and number are expressed by the morphology. POS tagging, particularly plays very important role in processing free-word-order languages because such languages have relatively complex morphological structure. It plays a fundamental role in various Natural Language Processing (NLP) applications such as word sense disambiguation, parsing, name entity recognition and chunking. Tagging for natural languages is similar to tokenization and lexical analysis for computer languages, except that we encounter ambiguities which are to be resolved. POS tagging is the process of assigning a part-of-speech or lexical class marker to each word in the given text. We address the problem of Part-of-Speech (POS) tagging of Urdu. The goal of this paper is to organize the ULP work in a way that it can provide a platform for ULP research activities in future. ![]() Finally, open issues and future directions for this new and dynamic area of research are provided. In addition, impact of ULP on application areas, such as, Information Retrieval, Classification and plagiarism detection is investigated. A review of state of the art research for the tasks such as Tokenization, Sentence Boundary Detection, Part of Speech tagging, Named Entity Recognition, Parsing and development of WordNet tasks are discussed. The aspects of the pre-processing activities such as stop words removal, Diacritics removal, Normalization and Stemming are illustrated. Characteristic, resource sharing between Hindi and Urdu, orthography, and morphology of Urdu language are provided. Initially, the available datasets for Urdu language are discussed. Conclusively, this paper attempts to describe in detail the recent increase in interest and progress made in Urdu language processing research. The core objective of this paper is to present a survey regarding different linguistic resources that exist for Urdu language processing, to highlight different tasks in Urdu language processing and to discuss different state of the art available techniques. Due to resources scarcity not enough work has been conducted for Urdu. Urdu is a South Asian Language, which is among the widely spoken languages of sub-continent. Most South Asian Languages are low resource languages e.g. corpora, WordNet, dictionaries, gazetteers and associated tools being developed for Western languages are customarily available. Western languages are termed as resource-rich languages. Provides access to CLAWS and USAS.Extensive work has been done on different activities of natural language processing for Western languages as compared to its Eastern counterparts particularly South Asian Languages.
