Abstract Semantic similarity between words is fundamental to various fields such as Cognitive Science, Artificial Intelligence, Natural Language Processing and Information Retrieval. According to Baeza-Yates and Neto [2] an Information Retrieval system “should provide the user with easy access to the information in which he is interested”.

Semantic similarity between words is fundamental to various fields such as Cognitive Science, Artificial Intelligence, Natural Language Processing and Information Retrieval. According to Baeza-Yates and Neto [2] an Information Retrieval system “should provide the user with easy access to the information in which he is interested”. Therefore, in this domain, relying on a robust semantic similarity measure is crucial for automatic query suggestion and expansion process. In this same context, we propose a method that uses on one hand, an online English dictionary provided by the Semantic Atlas project of the French National Centre for Scientific Research (CNRS) and on the other hand, a page counts based metric returned by a social website.

The technique of optical character recognition has a particular research interest that laboratories continue to improve and develop. This technique is a good alternative to entering text, the availability of various tools involved in the singularity of this service. Undoubtedly, the development of such tools will provide a considerable gain in time and costs. The basis of the Arabic language, prompted us to work hard for a successful control of its optical character recognition, otherwise it is necessary to develop another approaches, therefore an approach based on finding a word-image in a textimage. Finally, the objective of this work is to conduct research word-image in text image of the Moroccan official bulletin. Read More Read Less

In this paper through investigation and experimental result we show our proposed scheme which provides significant improvement in compression efficiencies. The main proposal of this paper is to reduce the memory space and the transmission time. We will also produce an experimental result which shows that our technique achieves good compression ratios. Reduction of compression ratio collection of large amount of data in almost all application is very important. In today’s era without computer application one can never thinks of database without compression. Whenever database comes compression plays very important role. Application may be stock exchange, banking, reservations in almost every field compression becomes primary things. With the help of compression one can make very big data in very less memory space. Disc input and output performance has bottleneck for very large databases. Database compression can be used to reduce disk input output bandwidth requirements for very big amount of data transfers. The authors explore and propose techniques managing the compressed database such that standard operations like retrievals, inserts,deletes and modifications are supported. Read More Read Less

Abstract Today many students produce a wrong and illegible handwriting. The traditional approach for handwriting teaching needs a long hour of handwriting practice, and teacher needs a lot of time to check the handwriting errors. Unfortunately, this is not feasible in many cases. In this paper we introduce an automated educational tool for Arabic Handwriting detection errors, such as the stroke... Today many students produce a wrong and illegible handwriting. The traditional approach for handwriting teaching needs a long hour of handwriting practice, and teacher needs a lot of time to check the handwriting errors. Unfortunately, this is not feasible in many cases. In this paper we introduce an automated educational tool for Arabic Handwriting detection errors, such as the stroke production errors, stroke sequence errors, stroke relationship errors and stroke interline errors, to help students to generate clear and readable handwriting. Firstly, we used an attributed relational graph to locate the handwriting errors. Secondly, an immediate feedback is provided to the students to correct them. Read More Read Less

Abstract E-Learning is gaining momentum in many directions. One important focus is the learning of second language. In this paper we address this issue by codifying the determining the most effective period for learning. We have outlined the critical period of such learning. We also discuss the multiple critical periods in this paper.... E-Learning is gaining momentum in many directions. One important focus is the learning of second language.
