Information research refers, in our context, to information retrieval to obtain further learning information from documents. However, automatic tools for learning information retrieval from these documents based on semantic tags are not yet effective. We propose here a model which aims at automatically annotating texts with semantic metadata. These metadata will allow us to index and extract learning objects from texts. This model is composed of two parts: the first part consists of a semantic annotation of learning objects according to their semantic categories (definition, example, exercise, etc.). The second part uses automatic semantic annotation which is generated by the first part to create a semantic inverted index able to find relevant learning objects for queries associated with semantic categories. We have implemented a system called SRIDOP, on the basis of the proposed model and we have verified its effectiveness. Read More Read Less

Abstract Development of a multimedia website for direct multimedia data distribution between the creators (photographers or music bands or movie producers) and the end users (images for websites or companies or magazines or music for daily web-surfers or any company or advertisement). The multimedia data gets stamped with some recognizable feature using steganography and thus offers great potential for securing of... Development of a multimedia website for direct multimedia data distribution between the creators (photographers or music bands or movie producers) and the end users (images for websites or companies or magazines or music for daily web-surfers or any company or advertisement). The multimedia data gets stamped with some recognizable feature using steganography and thus offers great potential for securing of data copyright and detection of infringers. This project report intends to give an overview of multimedia steganography, its uses and techniques. It also attempts to identify the requirements of a good steganography algorithm and briefly reflects on which steganographic techniques are more suitable for which applications.‘Palette-based image steganography using colour quantisation’,‘Bit manipulation’ are the various steganographic approaches for the multimedia data.

Social technology intersection indicates how a mobile device could facilitate communication and collaboration with many individuals and systems – the options available for social interaction using the technical capabilities of the mobile device to send SMS, call a friend, access the internet, etc. Mobile device is the beginning of something new in blended learning. Technology progress in the field of learning has evolved especially with the use of e-learning and now with the emergence of a new concept called m-learning due to mobile technologies, which are probably the most influential technology for teaching and learning in the next decade. Internet access remains inaccessible to most of our students. But almost all students have access to mobile technology. Nevertheless, the m-learning has some constraints in the use of mobile technologies such as the size of the screen which is too small for reading, battery life that is in constant progress but still low for elearning applications, user interfaces that are not user-friendly on most mobile phones and diversity of mobile devices and the rapidly changing trends suggest producing “LMS mobiles” adaptable to a wide range of mobiles. To avoid redundancy in the reproduction of content that exists in the e-learning environment, we combined in this approach the use of mobile device in the blended learning to offer to our students the opportunity to be mobile and use the mobile as the medium of information. In this paper the benefits of mobile-learning and its use in the INTTIC’s Moodle platform are presented. A new way to send information to different learners is developed, relying on the multimedia podcasting technology. This latter is still relatively new and not widely known. Read More Read Less
