Many Natural Language Processing and Information Retrieval methods are based on the extensive use of text corpora. The credibility of the results can be heavily influenced by the underlying corpus quality. Much research has been utilizing Arabic corpora into various tasks of Arabic Information Processing. In this paper we discuss a suite of metrics that can be used to ascertain the quality of A...

Transfer of enabling technology such as Information Technology (IT) has become a vital component of successful countries looking for technological innovation and techno-economic development nowadays. However, in the history of technology transfer in Arab countries, it is probably true that there has been more failure and disappointment than satisfaction and success in achieving the expected res...

Given its abundance of dialects, varieties, styles, and registers, Arabic lends itself easily to the study of language variation and change. It is spoken by some 300 million people in an area spanning roughly from northwest Africa to the Persian Gulf. Traditional Arabic dialectology has dealt predominantly with geographical variation. However, in recent years, more nuanced studies of interand i...

In this paper, we report on several software implementations that we have developed within Prague Arabic Dependency Treebank or some other projects concerned with Arabic Natural Language Processing. We try to guide the reader through some essential tasks and note the solutions that we have designed and used. We as well point to third-party computational systems that the research community might...

In the paper, there are analyzed and compared results of usable methods for discrepancies detection based on character n-gram profiles (the set of character n-gram normalized frequencies of a text) for English and Arabic documents. English and Arabic texts were analyzed from many statistical characteristics point of view. We covered some statistical differences between both languages and we app...

BACKGROUND Research on sleep health is lacking in developing countries, particularly among the Sudanese population. This contributes to a number of social and safety risks such as workplace injury, daytime sleepiness, automobile accidents, and more. The current study aims to validate three Arabic questionnaires related to sleep health, namely the Epworth Sleepiness Scale (ESS), Insomnia Severit...

The last two decades witnessed some advances in the development of an Arabic character recognition (CR) system. Arabic CR faces technical problems not encountered in any other language that make Arabic CR systems achieve relatively low accuracy and retards establishing them as market products. We propose the basic stages towards a system that attacks the problem of recognizing online Arabic cur...

Arabic handwriting recognition systems have been evaluated in public at the ICDAR conferences in 2005 and 2007. This contest provides well defined training data and unpublished test data, which makes the performance of those systems well comparable among each other. The development of the winning system of 2007 is described here in some detail. It is an HMM-based recognition system for Latin sc...

The aim of the work to be reported here is to explore the utility of prosodic information in language identification and discrimination tasks. The purpose of this study is to see whether prosodic patterns can be considered as reliable acoustic cues for the discrimination of Arabic dialects by investigating, via a perceptual experiment, if listeners are successful in identifying the Arabic diale...

Modern standard Arabic is usually written without diacritics. This makes it difficult for performing Arabic text processing. Diacritization helps clarify the meaning of words and disambiguate any vague spellings or pronunciations, as some Arabic words are spelled the same but differ in meaning. In this paper, we address the issue of adding diacritics to undiacritized Arabic text using a hybrid ...
