Printed Arabic Text Recognition using Linear and Nonlinear Regression

Ashraf A.
2017 International Journal of Advanced Computer Science and Applications  
However, due to complexity of Arabic language, recognition of printed and handwritten Arabic text remained untouched for a very long time compared with English and Chinese.  ...  Although, in the last few years, significant number of researches has been done in recognizing printed and handwritten Arabic text, it stills an open research field due to cursive nature of Arabic script  ...  [12] have proposed small-size printed Arabic text recognition approach based on hidden Markov (HMM) model estimation.  ...

Dynamic and Contextual Information in HMM Modeling for Handwritten Word Recognition

A.-L Bianne-Bernard, F. Menasri, R. Al-Hajj Mohamad, C. Mokbel, C. Kermorvant, Laurence Likforman-Sulem
2011 IEEE Transactions on Pattern Analysis and Machine Intelligence  
For modeling the contextual units, a state-tying process based on decision tree clustering is introduced.  ...  The results obtained show that contextual information embedded with dynamic modeling significantly improves recognition.  ...  We use the Hidden Markov Model Toolkit (HTK [48] ) for training and recognition.  ...

Finding Structure in Text, Genome and Other Symbolic Sequences [article]

Ted Dunning
2012 arXiv   pre-print
A variety of applications for these methods are examined in detail. These applications are drawn from the area of text analysis and genetic sequence analysis.  ...  Since these methods are abstract in nature, they can be applied in novel situations with relative ease.  ...  The hidden Markov model is used extensively in speech recognition. Hidden Markov models are described in section 1.4.  ...

Has Computational Linguistics Become More Applied? [chapter]

Kenneth Church
2009 Lecture Notes in Computer Science  
This paper provides a novel model for English/Arabic Query Translation to search Arabic text, and then expands the Arabic query to handle Arabic OCR-Degraded Text.  ...  The vector space model approached is modified in order to develop a more flexible clustering technique.  ...  Furthermore, as a big number of books and documents are available only in print especially the Arabic ones, they are not 'full text' searchable and they need applying the Arabic OCR process whose accuracy  ...

Automatic Language Identification in Texts: A Survey [article]

Tommi Jauhiainen, Marco Lui, Marcos Zampieri, Timothy Baldwin, Krister Lindén
2018 arXiv   pre-print
Finally, we identify open issues, survey the work to date on each issue, and propose future directions for research in LI.  ...  Today, LI is a key part of many text processing pipelines, as text processing techniques generally assume that the language of the input text is known.  ...  Acknowledgments This research was supported in part by the Australian Research Council, the Kone Foundation and the Academy of Finland.  ...

2019 The Journal of Artificial Intelligence Research  
Finally, we identify open issues, survey the work to date on each issue, and propose future directions for research in LI.  ...  Language identification ("LI") is the problem of determining the natural language that a document or part thereof is written in. Automatic LI has been extensively researched for over fifty years.  ...  Acknowledgments This research was supported in part by the Australian Research Council, the Kone Foundation and the Academy of Finland.  ...

Logarithmic opinion pools for conditional random fields

Andrew Smith, Trevor Cohn, Miles Osborne
2005 Proceedings of the 43rd Annual Meeting on Association for Computational Linguistics - ACL '05  
Most of this work has demonstrated the need, directly or indirectly, to employ some form of regularisation when applying CRFs in order to overcome the tendency for these models to overfit.  ...  Within NLP itself we have seen many different application areas, like named entity recognition, shallow parsing, information extraction from research papers and language modelling.  ...  Hidden Markov models have been applied to a number of labelling tasks in speech recognition (Rabiner, 1989) and natural language processing, including part-of-speech tagging (Kupiec, 1992) , information  ...
