E-Learning personalization topic has attracted the interest of many research studies in recent years. Several E-Learning personalization systems have been proposed. Each system implements a specific approach and includes a set of software components. However, many of these components are not reused. This paper presents first, a review of the literature related to the software components which are commonly used, then, a discussion about the different alternatives for reusing components of E-Learning personalization systems. The objective is to optimize the effort investment of the community in developing personalized E-Learning systems.

The integration of mobile devices in education is a new quite, which is commonly referred to as Mobile Learning. Mobile learning aims to facilitate and improve learning strategies that exploit individual learners' context, so that, they can learn from anywhere and at anytime using mobile devices. In order to let learners with disabilities take benefits from mobile learning systems, we propose in this paper an accessible and personalized mobile learning system to learners with disabilities which aims to adapt the learning activities to the learner's needs and/or preferences according to his/her disability's group taking into account the changing mobile context during the learning process.

The paper presents a new tool for the automatic evaluation of the usability of interactive systems (WIMP and Web). The proposed tool is based on a set of Web services, each of which service uses a set of ergonomic guidelines to evaluate particular graphical controls. One main advantage of the proposed tool is that it provides for flexible management of ergonomic guidelines independently of the evaluation engine. We illustrate the efficiency of our tool through an example of an evaluation support system.

The progress of our culture influences the systems that control our knowledge's, skills and behaviour. Our educational system has been influenced by this rapid change, and technology, is more and more used in learning systems. Our interest is particularly focused in e-assessment. It is the most fundamental operation of teaching and training in e-learning. It aims to increase the quality of education and teaching and seeks to heal problems and to determine until which it would be possible to carry out the objectives recommended by the process of teaching and the training. In this paper, we define a fundamental model of e-assessment in e-learning based on the analysis of the needs of learners and teachers using UML activity diagram. Therefore, we describe an innovative approach to specify a personalized e-assessment system using workflow. It aims to create an adapted workflow pattern for individual learner.

In this paper, we present an automatic query translation in Arabic for information retrieval. This system, implements a method for lexical disambiguation of terms in a query. To choose the best sense, each term of the query is projected on the French EuroWordNet and we extract his related concepts in order to form a semantic network. In a second time using the same type of network, but by integrating LSI (Latent Semantic Index), and extraction of contextual hidden links between the concepts of the list (listSRF). This list extracted by the automatic alignment by Mkalign tool's, from the knowledge base defined by the Monde Diplomatic parallel corpus. This tool will allow us to map between the relevant sentences in Arabic identified in our previous work with French sentences to build a listSRF. This list forms the basis of the lexical disambiguation method. Finally, we propose a mechanism for selecting the best sense of the ambiguous term of the query, based on the matching between each network corresponds to a word in the query with the network listSRF to extract an adequate sense with the highest degree of similarity. An evaluation and comparison are conducted to measure the quality of our translation system.

The use of computer learning games in education has significantly solved the problems of Game Generation in school. Therefore, using computer games in school increase students' motivation, and develop positive attitudes toward many subjects. In particular, using learning version of existing computer games was pointed out in many works that they have succeeded in improving student motivation, increase students' desire to learn and lead students to complete more difficult work. This paper describes a learning version of Pacman game with a case study in programming languages subject. This learning game is validated by classroom experimentation.

The need for a tool that takes a text and shortens it into a brief and succinct summary has never been greater than nowadays. With the huge amount of information on the internet and the necessity to get the essential of this information in a short time, the need for summarizers becomes everyday pressing, especially, for people with special needs like blind or elderly people. For those people it is vital to go directly to the essential information rather than having to read through many passages. So far and trying to reach human capabilities, research in automatic summarization has been based on hypothesis that are both enabling and limiting. Thus, if we want machines to mimic human abilities, then they will need access to the same large variety of knowledge. The implicit is affecting the orientation and the argumentation of the text and consequently its summary. Most of Text Summarizers (TS) are processing as compressing the initial data and they necessarily suffer from information loss. TS are focusing on features of the text only, not on what the author intended or why the reader is reading the text. In this paper, we address this problem and we present a system focusing on acquiring knowledge that is implicit. Such system helps people with special needs to acquire the essential data. We principally spotlight the implicit information conveyed by the argumentative connectives such as: but, even, yet .... and their effect on the summary.

Thanks to the advances in virtual reality and human modeling techniques, signing avatars have become increasingly used in a wide variety of applications like the automatic translation of web pages, interactive e-learning environments and mobile phone services, with a view to improving the ability of hearing impaired people to access information and communicate with others. But, to truly understand and correctly interpret the signed utterances, the virtual characters should be capable of addressing all aspects of sign formation including facial features which play an important and crucial role in the communication of emotions and conveying specific meanings. In this context, we present in this paper a simple yet effective method to generate facial expressions for signing avatars basing on the physics-based muscle model introduced by Keith Waters. The main focus of our work is to automate the task of the muscle mapping on the face model in the correct anatomical positions as well as the detection of the jaw part by using a small set of MPEG-4 Feature Points of the given mesh.

In this paper we describe OBSemE an ontology-based semantic metadata extraction system which implement our approach dedicated to the automatic extraction of semantic metadata for learning objects. The process of semantic metadata extraction is based on ontology metadata information extraction method's principles. This choice is due to the advantages of the use of ontologies. The input of our system is a set of LOM metadata elements respecting three requirements. The first requirement is that each chosen LOM data element must describe the educational content of the learning object. The second requirement is that the LOM data element must be required by most of the widely used LOM application profiles. The third requirement is that the LOM data element has to be mostly fulfilled by the learning object's authors in practice. The output of our system is a set of semantic metadata describing the learning object content. We have designed an RDF schema to encode semantic metadata with a computable formalism. We provide also some experimental results as a proof of the feasibility of our approach and the quality of our implementation.

This paper describes the construction of an application ontology for the legal domain. This ontology covering the semantic content of jurisprudence decisions can be deployed at several levels in our system for decisions research: improve the results of decision structuring, facilitate queries' formulation when accessing the system and finally optimize the search of decisions. We begin by presenting the methodology we have adopted for the ontology construction from textual jurisprudence decisions. We concentrate on the conceptualization stage by presenting our formal approach based on top level ontology as DOLCE and a core legal ontology. Then we will detail the deployment of the ontology at JDSM, the methodology of decision structuring decision that we have proposed..
