Parts Of Speech Tagger and Chunker for Malayalam – Statistical Approach
نویسنده
چکیده
Parts of Speech Tagger (POS) is the task of assigning to each word of a text the proper POS tag in its context of appearance in sentences. The Chunking is the process of identifying and assigning different types of phrases in sentences. In this paper, a statistical approach with the Hidden Markov Model following the Viterbi algorithm is described. The corpus both tagged and untagged used for training and testing the system is in the Unicode UTF-8 format.

Part-of-Speech Tagging and Chunking with Maximum Entropy Model
This paper describes our work on Part-ofspeech tagging (POS) and chunking for Indian Languages, for the SPSAL shared task contest. We use a Maximum Entropy (ME) based statistical model. The tagger makes use of morphological and contextual information of words. Since only a small labeled training set is provided (approximately 21,000 words for all three languages), a ME based approach does not y...

متن کاملTnt Tagger for Malayalam with Fuzzy Rule Based Learning
TnT is an efficient statistical Parts-of-speech (POS) Tagger based on Hidden Markov Model. TnT performs well on known word sequences. But, the performance degrades with increase in the number of unknown words. In this paper, we propose a method to overcome this performance degradation using fuzzy rules. Fuzzy rule based model is designed to provide TnT with sufficient information about the tag ...

This paper investigates certain methods of training adopted in the Statistical Machine Translator (SMT) from English to Malayalam. In English Malayalam SMT, the word to word translation is determined by training the parallel corpus. Our primary goal is to improve the alignment model by reducing the number of possible alignments of all sentence pairs present in the bilingual corpus. Incorporatin...
متن کاملCross-lingual Adaptation as a Baseline: Adapting Maximum Entropy Models to Bulgarian
We describe our efforts in adapting five basic natural language processing components to Bulgarian: sentence splitter, tokenizer, part-of-speech tagger, chunker, and syntactic parser. The components were originally developed for English within OpenNLP, an open source maximum entropy based machine learning toolkit, and were retrained based on manually annotated training data from the BulTreeBank...
