    Towards a framework, for adapting information and communication technologies to enterprise providers, to promote their products
    (2015-05-19) Mellah, Hakima; Matouk, Fatma Zohra
    The present work emphasizes three representative aspects of ICT such as the media, modalities and modes, and meet the following requirements: -Understanding how product suppliers, also considered as companies business managers, adapt to ICT -Integrating user preferences in choosing the proper interaction mode -Showing the social networks effect in promoting products to assure best sells -Proposing a solution that supports the way in which ICT will be pretty well used to represent and express the user's need -Projecting or specifying the proposed solution to the Arab world -Presenting a case of actual study, limited to one job category

    Using tags Associated to Resources to Build Ontologies
    (2014-08-11) Keddari, Djalila; Mellah, Hakima; Benna, Amel
    Social tagging has recently emerged in collaborative web (Web 2.0) as a support shared resources organization allowing users to categorize these resources (web pages, video, images) by associating them with keywords, called tags. However, the use of uncontrolled tags poses several problems, namely ambiguity, writing variations (many tags denoting the same concept) as well as tags volume. The latter has led to tags classification into several clusters using the K-Means algorithm. The purpose of this work is that from tags clusters and their hierarchical classification, it would be important to build an ontology as these tags have a semantic aspect and are expressed by users who used the tagged resources. Building ontologies based on resource tag is a way to make automatic their building without requiring experts in their building as usual. Reproducing these tags clusters into ontological form is a way to share its knowledge with other users. We aim through this paper to build an ontology based on tags. A technical approach to form ontological portions, starting from tags clusters is based on semantic distance existing between tags. As tags clusters have a semantic relationship, the semantic distance between clusters is used to merge ontological portions into a global ontology

    Matching Resources in Social Environment
    (2012-06-28) Benna, Amel; Mellah, Hakima; Choui, Islam; Oualid, Ali
    User comments on the web are becoming more and more important. We focus, in this paper, on the use of user-defined tags for annotating resources to identify links between them. These links are based on a social context of the resource, obtained by applying k-means classification method and a hierarchi- cal classification of tags within a cluster. The resources are re-assigned to this classification to facilitate the search process. The ranking of results is performed according to their degree of relevance, by evaluating a similarity score between the tagged contents, in hierarchical clusters of tags, and the user request. The re- sults of the evaluation, on the social bookmarking systemdel.icio.us, demonstrate significant improvements over traditional approaches.

    A Communication model of distributed information sources bacteria colonies inspired
    (IEEE, 2006) Mellah, Hakima; Hassas, Salima; Drias, Habiba
    The implementation of communication organizational strategies constitutes an essential performance factor. Nowadays, the organization becomes companies competitiveness element (organizational structures), networks, knowledge and competences management, and cooperation. This, to be better reactive to ensure the competing character, to support better new information technologies, concerning the data exchange inside as outside an organization. The information systems specification gives a partial description of the organization, which integrated with other descriptions is regarded as being the organization model. Using the abstraction level of an information system (information source) was proven to be not sufficient to face the conflicts confronted by the organizations. These conflicts are the improvement and the change with an aim of adapting constantly to the environment new requirements. These latter are essential to support the dynamic character which tends to characterize the current organizations and which is often nature taken. In order to implement this dynamism, we took as a starting point the biological sciences and more particularly the bacteria colonies. This paper presents a correspondence model between a communication system of distributed information sources and a bacteria colony

    Web Services based Approach for Integrating Multimedia Content
    (SciTePress, 2012-06-28) Lebib, Fatma-Zohra; Mellah, Hakima; Amghar, Youssef
    Multimedia content is derived from various autonomous, distributed and heterogeneous content sources. To address problems posed by content sources heterogeneity, a service-oriented architecture is proposed to assure a dynamic integration of multimedia content. In this work we propose a model that we call MaaS (for Multimedia as a Service), through which multimedia content providers expose their content. Once the MaaS is discovered, its classification into category of concepts, based on domain ontology, is made. However, content access is done through a concept hierarchy. The sport domain is used to validate the proposed model.

    Building a social network, based on collaborative tagging, to enhance social information retrieval
    (2012-03-24) Benna, Amel; Mellah, Hakima; Hadjari, Karima
    Web 2.0 technologies put user at the center of data production and introduce a strong social collaboration. Therefore, the techniques used in traditional information retrieval systems do not meet the requirements of users who want to take into account their social preferences. The idea reported in this paper is to include not only the social context of the user but also that of the resource. In the social network that we consider, the user social context brings his interests, which are captured from a collaborative tagging system, while the resource social context is related to clusters of tags, obtained by classification method, and users’ opinions according to their expertise level on the resource. The results of our experiment evaluation on real-world datasets (crawled from delicious folksonomy) demonstrate significant improvements over traditional retrieval approaches.

    Indexing multimedia content for textual querying: A multimodal approach
    (2013-07) Amrane, Abdesalam; Mellah, Hakima; Amghar, Youssef; Aliradi, Rachid
    Multimedia retrieval approaches are classified into three categories: those using textual information, and those using low-level information and those that combine different information extracted from multimedia. Each approach has its advantages and disadvantages as well to improving multimedia retrieval systems. The recent works are oriented towards multimodal approaches. It is in this context that we propose an approach that combines the surrounding text with the information extracted from the visual content of multimedia and represented in the same repository in order to allow querying multimedia content based on keywords or concepts. Each word contained in queries or in description of multimedia is disambiguated by using the WordNet in order to define its semantic concept.
