This paper presents a Framework for converting a class diagram into an XML structure and shows how to use Web files for the design of data warehouses based on the classification UML. Extensible Markup Language (XML) has become a standard for representing data over the Internet. We use XSD schema for define the structure of XML documents and validate XML(More)
Agent technology is emerging as a powerful approach for the development of complex system. Mobile agent is a program that can migrate as a whole around network and can communicate with its environment and other agent. Among application for mobile agent: manufacturing, electronic commerce, network management, health care, and entertainment. In this paper we(More)
We present a new approach to the matching of 2D shapes using XML language and dynamic programming. Given a 2D shape, we extract its contour and which is represented by set of points. The contour is divided into curves using corner detection. After, each curve is described by local and global features; these features are coded in a string of symbols and(More)
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(More)
In this paper we present the design and the implementation of Mobile-C, an IEEE Foundation for Intelligent Physical Agents (FIPA) compliant agent platform for mobile C/C++ agents. Such compliance ensures the interoperability between a Mobile-C agent and other agents from heterogeneous FIPA compliant mobile agent platforms. Also, the Mobile-C library was(More)
With the use of ontologies in several domains such as semantic web, information retrieval, artificial intelligence, the concept of similarity measuring has become a very important domain of research. Therefore, in the current paper, we propose our method of similarity measuring which uses the Dijkstra’s algorithm to define and compute the shortest path.(More)
In this paper we present a new method for writing an approximate description of 2D/3D objects in text form using XML language. First, the outline of the shape is divided into parts according to N angular and M radial sectors (or bin), each Bin contains a portion of the contour; this portion is divided at the inflexion points into convex and concave sections(More)
