In the last decades, the web has experienced a quantitative explosion of digital data handled by companies or organizations, prompting web users to switch to NoSQL system dedicated to Big Data in order to support large web sites destined for a very big audience due to the scalability and high availability of this system. In the other hand, the semantic web technologies has emerged with their considerable...
Nowadays, more and more people possess mobile devices (laptops, tablets, smart-phones, etc), capable of creating and sharing documents (which generally are multimedia oriented) via internet anytime and anywhere (home, office, hospital, etc). People should have full control on how they receive a multimedia content, depending on their current condition: when in a meeting, displaying a text instead of...
This paper describes a Framework for achieving the migration of relational databases to other types of databases(OO, OR, XML), based on a meta-model which plays the core role of the framework in establishing migration, exploiting the different object concepts including inheritance, aggregation, and composition. The realization of the meta-model is based on the principle of semantic enrichment and...
NoSQL databases are designed to solve data processing problems in volume. Growth data today pushes us to think about new concepts and approaches for converting data from a source database to a NoSQL database. This paper describes some approaches, methods of migration, database reverse engineering, and offers a migration approach from a relational database to a Document-oriented database NoSQL (MongoDB)...
The emergence of pervasive computing and user mobility leads to the need for dynamic adaptation of user interaction on the documents which generally are multimedia oriented. The exchange of multimedia documents has a special place. In this paper we propose an approach for modeling context in pervasive computing environments for multimedia documents adaptation. Many researchers work in the area of...
Multimedia documents can be accessed at anytime and anywhere on a wide variety of devices, such as laptops, tablets and smartphones. The heterogeneity of devices and user preferences has raised a serious issue for multimedia contents adaptation. Our research focuses on multimedia documents adaptation with a strong focus on interaction with users and exploration of multimodality. We propose a semantic...
Heterogeneous communications are significantly important for interoperability generally and for mobile agent systems interoperability particularly. But the mobility of the agents presents real obstacles to the reliability of message transmission between heterogeneous agents. In this paper we propose a reliable framework of communication for heterogeneous agent using middleware technologies. This framework...
This paper presents a part of a generic approach for transposition models of any data source to the ontology and vice versa using Model Driven Architecture (MDA). We present the general process of our approach by focusing on the transposition from data source to ontology: Data source is based on a unique and single model also for ontology, the cooperation of software engineering and knowledge engineering...
Multimedia documents can be accessed at anytime and anywhere on a wide variety of devices, such as laptops, tablets and smartphones. The heterogeneity of devices and user preferences has raised the problem of these documents adaptation according to user context condition and device characteristics. In this paper, we propose a semantic multimodal profile for multimedia documents adaptation. Thus, we...
XML is considered as the most widely used standard to represent, structure and share data via the Web. XML Schema and DTD ensure the content structuring of XML documents; these languages are used to determine the grammar to use in XML instances in order to describe a given domain. However, the requirements of the semantic web are beyond what is syntactic and structural, and focus increasingly to the...
MAS is a powerful paradigm in nowadays, is become promising means for the development of distributed systems, however its disadvantage is that it lacks the interconnection with semantic web such as Ontology Web Language. In this article, we aim to present and to implement a semantic knowledge model of an agent suitable for discrete environments by using the Jena : is a Java framework for the creation...
Most of data on the Web are still stored in relational databases. Therefore, it is more important to make the correspondence between relational databases (RDB) and ontologies for storing the Web data. In this paper, we present an new approach to map the data stored in relational databases into the Semantic Web, we exploit simple mappings based on some specifications of the database schema, and we...
This paper describes a methodology for mapping UML Class into an XML schema. The structure of a class diagram is then translated element by element to XML schema using stepwise procedures. We use XSD schema for define and validate the structure of XML documents. In this paper we use a mathematical formulation model for the mapping UML Class into XML document, and a framework has been developed to...
We propose a new method for shape recognition and retrieval based on dynamic programming. Our approach uses the dynamic programming algorithm to compute the optimal score and to find the optimal alignment between two strings. First, each contour of shape is represented by a set of points. After alignment and matching between two shapes, the contours are transformed into a string of symbols and numbers...
In this paper, we investigate the existence of mild solutions of second-order initial-values problems for a class of semilinear differential inclusions with nonlocal conditions. By using suitable fixed-point theorems for multi-valued maps, we study the case where the multi-valued map F has convex or nonconvex values.
