Named Entity Recognition plays a major role in various Natural Language Processing (NLP) fields like Information Extraction, Machine Translations and Question Answering. Unfortunately Kashmiri language which is a scarce resourced language has not been taken into account. This paper describes the problems of NER in the context of Kashmiri Language and provides relevant solutions. Keywords Named Entity, Named Entity Recognition, Natural language process, Kashmiri language text. I. Introduction is as follows. The term Named Entity (NE) was evolved during the sixth (1) “Micromax”represent anorganization and “ Dec19, 2014” Message Understanding Conference (MUC -6, 1995).Named represent dateand “smartphone” represent entity and “had Entity Recognition (NER) is also knows as entity identification is a launched its on” represent others. subtask of information extraction (IE). NER extracts and classifies The named entities may be of any type such as given below in the true Named Entities in text. NER system is widely used in a table. different tasks of Natural Language Processing (NLP) and in many commercial applications on internet like Search Engine Table 1: Different named entities .Named Entity Recognition (NER) is a process of searching the S.NO NE Tag DEFINITION (example) text to detect entities in a text and to classify them into predefined 01 ORG Name of organization (Micromax) classes such as the names of persons, organizations, locations, date, time, Designations, Measures, , abbreviations and brand 02 PER Name of person (Amir) etc. Construction of a Named Entity 03 COUNTRY Name of Country (India) Recognition (NER) system becomes challenging if proper 04 OTHER Not a named entity resources are not available. Gazetteer lists are often used for the development of NER systems In many resource-poor languages like kashmiri gazetteer lists of proper size are not available, II. Literature Survey but sometimes relevant lists are available in English. 1. Amarappa and Sathyanarayana, 2012, came up with a paper In Indian languages kashmiri is a most popular language in on „Named Entity Recognition and Classification (NERC) in northern part of India. Kashmiri languagethe current number of Kannada language’, that built a SEMI-Automatic Statistical its speakers will be around four million. Kashmiri is also spoken Machine Learning NLP models based on noun taggers using by Kashmiris settled in other parts of India, and other countries. HMM. Kashmiri language belongs to the Dardic sub-group of the Indo- The challenges and issues faced for Kannada language are listed Aryan group of languages. by them are 1. No capitalization NER based approaches are shown in fig1 given below. 2. High phonetic characteristic of Brahmi script. 3. Non-availability of large gazetteer lists MICROSOFT APPLE NOKIA 4. Lack of standardization and spelling 5. Number of frequently used words (common nouns). ORGANIZATION Their proposed NER system for Kannada receives the HUMAN MUSLIM unannotated text file containing the Kannada document, FOOD ENTITY NER COMMUNITY HINDU recognizes the NE‟s and generates an annotated text document CURRENCY SIKH file. Further the output of NERC system is subjected to a suitable cryptographic algorithm to secure the structured corpus. They NUMERIC OTHERS came up with 13 noun taggers for NER like person name (NNP), location name (NNL), organization name (NNO),etc. Hidden DATE TIME PERCENT Markov Model (HMM) is a supervised learning technique and a statistical model with generalized learning method. It is used Fig. 1 : A Named Entity recognition split into more specific Named to develop a NER with symbolic, statistical, connectionist and Entities hybrid natures. NE‟s and NE Tags are defined with examples in this paper. For example consider the English sentence like: 2. Kaur and Vishal Gupta, 2012, built a „NER for Punjabi‟ Micromaxhad launched its first smartphone on Dec 19, 2014. using rule based and list look up approaches. As mentioned earlier, After performing the named entities on these sentences the result Punjabi is also a language with high clung and inflections, which www.ijarcst.com 209 © All Rights Reserved, IJARCST 2013 International Journal of Advanced Research in ISSN : 2347 - 8446 (Online) Computer Science & Technology (IJARCST 2015) Vol. 3, Issue 2 (Apr. - Jun. 2015) ISSN : 2347 - 9817 (Print) leads to linguistic problems.

Kashmiri language is written from right to left. • One major issue with Kashmiri language is that it requires language experts. • The training and testing for Kashmiri language is difficult task for the person who is not language expert of Kashmiri. • No Kashmiri language conversion in Google translator. • 05. No inbuilt knowledge base. IV. Conclusion and Future Work In this work, the method for extracting named entities from data of various domains has been presented which is a system useful in the identification and classification of names. The work for Kashmiri NER is very complex due to the nature of Kashmiri language which is in free order and lacks of research work in Kashmiri text. References [01] Joel , N.
