“…There are many techniques followed in Named Entity tagging. Named Entity Recognition was done different language using kannada by Amarappa [1]. The techniques used include multi engine approach technique by Asif Ekbal [2] using Bengali language, They considered root of words, POS, combined word and POS , Dictionary of named entities as features to build the system.…”

Named Entity Recognition is the process of identifying and recognizing named entities such as person, organization, location, date, time and money in the text documents. Named Entity Recognition is a subtask of Information Extraction. Information Extraction is the process of extracting the relevant data from documents. It is one of the research areas in Natural language processing. In this project implement a named entity recognizer using the hybrid approach that uses both Rule based and Hidden Markov Model in succession, which identifies only person, location and organization names respectively. Input data for proposed Named Entity Recognition system is any text document related to the any domain but limited size corpora respectively in Tamil language. In this system are tagging each word by using POS tagger and then imposing certain rules such as Lexical features and use some Gazetteers. HMM model using E-M algorithm is taken output data from trained as input to recognition system. The main purpose of this system identifies unknown entities and solves the problem of same name entity in different positions in the same document. The system is measuring the recall and precision parameters calculate the F-measure score. Goal of this project is to improve the performance of NER system to achieving high F-measure score.

“…S. Biswas, M. K. Mishra, S. Acharya and S. Mohanty [17],the authors have developed a Named Entity Recognition system for Indian languages particularly for Hindi, Bengali, Oriya, Telugu using hybrid machine learning approach that used MaxEnt and HMM successively. They showed that with the preliminary data training through MaxEnt and appropriate classifier for error correction in the final recognition process through HMM, the performance of the proposed NER system can be greatly enhanced as compared to using only a single statistical model.…”

Named entity recognition is a process and study of identification of entities that are proper nouns and classifying them to their appropriate pre-defined class, also called as tag. Named entity recognition is also called as entity chunking, entity identification and entity extraction. It is a sub task of information extraction, where structured text is extracted from unstructured text. Popular applications of NER are machine translation, text mining, data classification, question answering system. This paper presents a survey of different NERC techniques, approach, observations and features for

“…In Kannada Language, some works on Kannada Morphology are reported in [35] [56]. In our earlier work [37] we have carried out NERC work in Kannada using HMM on a limited corpus of 10,000 tokens, however the works on NERC in Kannada are yet to be investigated and implemented. This motivated us to take up NERC in Kannada as the proposed Research area.…”

Named Entity Recognition and Classification (NERC) is a process of identification of proper nouns in the text and classification of those nouns into certain predefined categories like person name, location, organization, date, and time etc. NERC in Kannada is an essential and challenging task. The aim of this work is to develop a novel model for NERC, based on Multinomial Naïve Bayes (MNB) Classifier. The Methodology adopted in this paper is based on feature extraction of training corpus, by using term frequency, inverse document frequency and fitting them to a tf-idf-vectorizer. The paper discusses the various issues in developing the proposed model. The details of implementation and performance evaluation are discussed. The experiments are conducted on a training corpus of size 95,170 tokens and test corpus of 5,000 tokens. It is observed that the model works with Precision, Recall and F1-measure of 83%, 79% and 81% respectively.
