In this paper, we survey and compare proposed solutions (such as models and architectures) that could contribute to solving this problem of mobile access to the Web of Data with intermittent Internet access. These solutions are discussed in relation to the underlying network architectures and data models considered. We present a conceptual study of peer-to-peer solutions based on gossip protocols dedicated to design the connected overlay networks. In addition, we provide a detailed analysis of client-server and data replication systems generally designed to ensure the local availability of data on the system. We conclude with some recommendations to achieve a connected architecture that provides mobile contributors with local access to the Web of data.
Integration of Ontology Transformation into Hidden Markov Model
Information Dynamics and Applications

Ontology properties (relationships between classes) and ontology classes are taken as HMM symbols and states, respectively. Knowledge is represented in many different fields using the central element of the Semantic Web dubbed ontology. The authors employed machine learning technologies like HMM to add knowledge to these ontologies or to extract knowledge from within them. The meaning obtained from ontologies is not described during this task. The ontology triples that were extracted using SPARQL queries are used in this paper to transform the ontology into an HMM in order to handle this semantic. The Pizza ontology has been used to implement this method, which is based on lightweight ontologies.

A Survey on Multimedia Ontologies for a Semantic Annotation of Cinematographic Resources for the Web of Data

Multimedia resources like videos, audios, and photos are increasingly common in contemporary Web content. Cinematographic works (also known as film contents) stand out among these resources as one of the most recent attractions on the Internet. An important tool employed recently in the semantic indexation of digital resources and film content is ontological annotation. This paper studies the current multimedia ontologies related to the film contents on the web. The relevant indicators were discussed comparatively, and some open issues were reviewed in details. In this way, the authors managed to integrate the metadata related to online films practically into the web of data.

The issue of improving the living conditions of senior citizens through intelligent computer systems is discussed in this article. We present a state of the art on intelligent computer systems techniques, in particular ontologies for improving the living conditions of seniors, in order to highlight some shortcomings and take a position accordingly.

We present the conceptual and technical aspects of this architecture as well as a theoretical analysis of the different characteristics. We then evaluated it experimentally and results show the relevance of considering geographical positions during data exchanges and of integrating RDF graph replication to ensure data availability in terms of requests completion rate and resistance to crash scenarios.
Modular Ontology Design: A State-of-Art of Diseases Ontology Modeling and Possible Issue

Are obtained from these techniques the monolithic or modularized Ontologies. When is difficult to reuse some concepts of monolithic ontologies, modularized Ontologies facilitate ontology management, understandability and reuse. This paper aims to survey on ontology modularization techniques and their contribution in biomedical ontologies design. Modularization reposed on appropriated techniques and some challenges related to ontology reused, scalable querying, collaborative authoring, and distributed reasoning. For most of disease ontologies, more especially ontologies which reused IDO, these challenges are not considered, and most of them are implemented with OWL language and the novel mode to construct ontology’s purpose is to facilitate reuse and interoperability of ontologies ensured by modularization.

Some new computational techniques (semantic web technologies) are needed to manage the large repositories of sociocultural data and to discover useful patterns and knowledge from them. This paper presents a virtual activity ontology modeling approach, in the case of sociocultural knowledge sharing and co-construction named Ontoshare. Our modeling approach is based on Engeström's Human Activity Theory (HAT). With Ontoshare we designed how Internet users could build the content of a sociocultural Knowledge Management System (KMS); this vocabulary also organises data, facilitates information retrieval by introducing a semantic layer in social web platform, we plan to implement. The platform could be considered as a « collective memory » which will allow communities to share, co-construct and discover sociocultural knowledge in the Camer...

Nous avons explore plusieurs mecanismes pertinents proposes dans la litterature, dedies a des problematiques differentes et pouvant constituer des points importants pour nos futures contributions. Notre objectif principal etant de proposer des outils dedies a des situations de mobilite dans des environnements ou l’acces internet est peu fiable, nous nous sommes interesses particulierement a comparer des approches (P2P, DHT, etc.) permettant de realiser un scenario de fog/edge computing particulier qui est l'acces mobile restreint et local a des donnees liees contextuellement pertinentes et partagees. Dans cette optique, nous avons focalise une partie de nos recherches bibliographiques sur les protocoles dits de « gossip » (ou protocoles epidemiques) qui s’averent bien adaptes au caractere dynamique des reseaux.

MoRAI: Geographic and Semantic Overlay Network for Linked Data Access with Intermittent Internet Connectivity

The method is based on the set theory, edges and feature similarity. We first determine the set of concepts that is shared by two ontologies and the sets of concepts that are different from them. Then, we evaluate the average value of similarity for each set by using edges-based semantic similarity. Finally, we compute similarity between ontologies by using average values of each set and by using feature-based similarity measure too.
