In this paper we conduct a comparative study between two stemming algorithms: khoja stemmer and our new stemmer for Arabic text classification (categorization), using Chisquare statistics as feature selection and focusing on decision tree classifier. Evaluation used a corpus that consists of 5070 documents independently classified into six categories: sport, entertainment, business, middle east...

one of the most important task of the researchers after selection the research topic, is search for various sources and references for gathering data and information about the subject. undoubtedly this search has been more extensive and accurate, value and credibility. accordingly should be said that the number and variety of citation sources and credit is one of the criteria in evaluation acad...

We propose a novel modeling framework for automatic diacritization of Arabic text. The framework is based on Markov modeling where each grapheme is modeled as a state emitting a diacritic (or none) from the diacritic space. This space is exactly defined using 13 diacritics and a null-diacritic and covers all the diacritics used in any Arabic text. The state emission probabilities are estimated ...

We present an algorithm for a priori Arabic optical Font Recognition AFR . The basic idea is to recognize fonts of some common Arabic words. Once these fonts are known, they can be generalized to lines, paragraphs, or neighbor non-common words since these components of a textual material almost have the same font. A decision tree is our approach to recognize Arabic fonts. A set of 48 features i...

arabic prose passed during its development through different stages; and arabic literature in general was a pad of the types of literary that emerged for it in the present era in the field of principles and rules. some believe that the literary genres and systems prose are taken from the west. while if we look closely, we find models of them in the old arab literature, though contemporary men o...

Compared to other languages, there is still a limited body of research which has been conducted for the automated Arabic Text Categorization (TC) due to the complex and rich nature of the Arabic language. Most of such research includes supervised Machine Learning (ML) approaches such as Naïve Bayes (NB), K-Nearest Neighbour (KNN), Support Vector Machine and Decision Tree. Most of these techniqu...

literature severely needs innovation and renewal to exit from weakness and inanition mood and there must be a strong connection between renewal and literal- cultural heritage. the renewal must prepare context to create new literal genres in addition to utilizing positive aspects of other cultures. so, this type of renewal is positive. hadith of isa ibn hisham, essay of mohammad al mavilhi is co...
