  • In order to considerably reduce the ambiguity rate, we propose in this article a disambiguation approach that is based on the selection of the right diacritics at different analysis levels. This hybrid approach combines a linguistic approach with a multi-criteria decision one and could be considered as an alternative choice to solve the morpho-lexical ambiguity problem regardless of the diacritics rate of the processed text. As to its evaluation, we tried the disambiguation on the online Alkhalil morphological analyzer (the proposed approach can be used on any morphological analyzer of the Arabic language) and obtained encouraging results with an F-measure of more than 80%.

  • Cyberbullying is a problem that is faced in many cultures. Due to their popularity and interactive nature, social media platforms have also been affected by cyberbullying. Social media users from Arab countries have also reported being a target of cyberbullying. Machine learning techniques have been a prominent approach used by scientists to detect and battle this phenomenon. In this paper, we compare different machine learning algorithms for their performance in cyberbullying detection based on a labeled dataset of Arabic YouTube comments. Three machine learning models are considered, namely: Multinomial Naïve Bayes (MNB), Complement Naïve Bayes (CNB), and Linear Regression (LR). In addition, we experiment with two feature extraction methods, namely: Count Vectorizer and Tfidf Vectorizer. Our results show that, using count vectroizer feature extraction, the Logistic Regression model can outperform both Multinomial and Complement Naïve Bayes models. However, when using Tfidf vectorizer feature extraction, Complement Naive Bayes model can outperform the other two models.

  • Natural texts are analyzed to obtain their intended meaning to be classified depending on the problem under study. One way to represent words is by generating vectors of real values to encode the meaning; this is called word embedding. Similarities between word representations are measured to identify text class. Word embeddings can be created using word2vec technique. However, recently fastText was implemented to provide better results when it is used with classifiers. In this paper, we will study the performance of well-known classifiers when using both techniques for word embedding with Arabic dataset. We applied them to real data collected from Wikipedia, and we found that both word2vec and fastText had similar accuracy with all used classifiers.

  • Ziperol, anti-tussive, is considerably bitter. Therefore, it is necessary to mitigate the bitterness in ziperol syrup for children. In this experiment, it was attempted to mitigate the bitterness of zipeprol by means of polymers such as $\beta$-cyclodextrin, arabic gum, HPMC(hydroxypropyl methylcellulose), PEG 2000(polyethyleneglycol 2000), PVP(polyvinylpyrrolidone). Caffeine was used as the reference standard of bitterness. In the result of this experiment, $\beta$-cyclodextrin, would mitigate the bitterness of zipeprol more largely than any other polymers. Arabic gum was the second choice which would mitigate the bitterness of zipeprol.

  • This study was analyzed three basic patterns of the Islamic arts. These are natural flora, geometrical and calligraphy pattern. Islamic belief in Aniconism, doctrine of unity and worship of arabic language demanded delicate, decorative, and abstract patterns instead of patterns of real image. Natural flora pattern was classified into arabesque and various flower patterns. Muhammad commands that "The artist who fashions a representation of living things is competitor of God and therefore destined to eternal damnation, so if you want to represent living things, you should only depict flowers and trees". Then the natural flora patterns developed into main Islamic pattern. Geometric pattern was composed of geometrical elements like, circle, trigon, square, rectangle, pentagon, hexagon, octagon or other polygons, stars or motifs with straight or curved lines. Circle symbolized ′celestial′ sphere and crystal of the lower octagon symbolized ′earthly existence′. Therefore if the circle join with the octagons, it means fusion of celestial and earthly existence. Another important influence on the Islamic art was the calligraphy pattern, the writing of Arabic language. The major language of calligraphy pattern was Arabic script and often Persian script. Calligraphy pattern was composed of Kufic and Cursive script. The cursive script was developed various forms. The Islamic tenet prohibit depiction of sacred images, the sacred Arabic calligraphy such as ′Alla′ or ′Mohammad′ was substituted of them. And the content of calligraphy pattern was used with Quranic phrases. The aesthetics of Islamic patterns analyzed aesthetic of ′rhythmic lines′, aesthetic of ′unity in multiplicity′, aesthetic of tessellation and aesthetic of harmony. On the textiles of the Islamic culture, the arabesque, floral, geometric and calligraphy patterns were frequently used.

  • Islam toot a great interest in the utility sciences such as mathematics and astronomy as it needed them for the religious reasons. It needeed geometry to determine the direction toward Mecca, its holiest place: arithmetic and algebra to settle the dates of the festivals and to calculate the accounts lot the inheritance; astronomy to settle the dates of Ramadan and other festivals. Islam expanded and developed mathematics and sciences which it needed at first for the religious reasons to the benefit of all mankind. This thesis focuses upon the golden age of Islamic culture between 7th to 13th century, the age in which Islam came to possess the spirit of discovery and learning that opened the Islamic Renaissance and provided, in turn, Europeans with the setting for the Renaissance in 14th century. While Europe was still in the midst of the dark age of the feudal society based upon the agricultural economy and its mathematics was barey alive with the efforts of a few scholars in churches, the. Arabs played the important role of bridge between civilizations of the ancient and modern times. In the history of mathematics, the Arabian mathematics formed the orthodox, not collateral, school uniting into one the Indo-Arab and the Greco-Arab mathematics. The Islam scholars made a great contribution toward the development of civilization with their advanced the development of civilization with their advanced knowledge of algebra, arithmetic and trigonometry. the Islam mathematicians demonstrated the value of numerals by using arithmetic in the every day life. They replaced the cumbersome Roman numerals with the convenient Arabic numerals. They used Algebraic methods to solve the geometric problems and vice versa. They proved the correlation between these two branches of mathematics and established the foundation of analytic geometry. This thesis examines the historical background against which Islam united and developed the Indian and Greek mathematics; the reason why the Arabic numerals replaced the Roman numerals in the whole world: and the influence of the Arabic mathematics upon the development of the modern mathematics.

  • Spray dried powdered juice was processed from concentrated extract of jujube(Zizyphus jujuba MILLER). Spray drying of the extract solution could not be operated to have powder product by itself over whole concentration range and required addition of some carrier or support material. The concentrated extract of 26$^{\circ}$Bx was combined with carrier material solution to have a final concentration of 30$^{\circ}$Bx, and then spray dried. Proper addition level of carrier solid for physical and flavor quality of the powder product was determined to be 1 : 1 ratio to jujube solid. Combined use of maltose and gum arabic produced the best quality product among the studied carrier materials, which were maltose, dextrin, condensed milk and gum arabic. Enzymatic treatment in extraction process could increase the yield by 13~39%, but hurt the sensory quality of powdered juice. Treatment by 0.5% pectinase(0.05 unit/ml) may be used with lesser quality change for improved yield.

  • Up to now it has been widely conceived that mariner's compass was introduced to Europe from China via the Arabic people. But the proofs to support the above orthodox dissertation have not been found yet. In general it has been approved that the Chinese used the compass for navigation in the 11th century and European did in the 12th century. During the above period the communication between the Europe and the China was made only by the mediation of the Arabic people. But it is known that the beginning of Arabic people's compass usage was one century later than that of the European. It may raise a historical question about ‘was mariner's compass introduced to Europe from China via the Arabic people\ulcorner’ In this paper the authors tried to prove the simultaneity of the mariner's compass usage by the European with the Chinese by reviewing historical materials and modern researches. The results are as following; The first, there is a strong similarity in the evolving steps of compass appliance of both civilizations, such as from using magnetized and pivoted needle to fixing card thereto. Second, the Chinese and the European started to use the mariner's compass almost at the same time, and they developed it independently.
