With the recently increasing interest for opinion mining from different research communities, there is an evolving body of work on Arabic Sentiment Analysis. There are few available polarity annotated datasets for this language, so most existing works use these datasets to test the best known supervised algorithms for their objectives. Naïve Bayes and SVM are the best reported algorithms in the Arabic...
In this paper we have studied strained structures wells based on GaInAsSb over GaSb substrate. The GaSb substrates allow the mesh accordability with the GaInAsSb solid solution in the range 1.7–3.5 μm. The conduction band and valence discontinuities are evaluated. A Basic source-detector direct transition has been demonstrated at 2–3 μ m. The III-V based GaSb components have many applications in optical...
Today, to effectively meet the needs of users, multilingual information retrieval is an important issue regarding to the continually increasing volume of information in various languages. This paper addresses indexing and retrieval in a trilingual corpus: Arabic, French, English. The proposed system is founded on a knowledge representation formalism, namely semantic graphs which supports a domain...
