    Since the first implementations of its principles, the Semantic Web presented a field of free work to ensure its integration and adaptation to the various domains of research. The application of Semantic Web technologies into the process of search in a collection of SMIL documents appears a promising initiative seen the evolution of this language through its various versions. In this paper we propose a semantic search tool in a collection of SMIL documents; this tool adopts a procedure composed of three modules: description, interrogation and representation of the results. We employ for the first module metadata commonly used to annotate information semantically, and for the second we solicit languages of Semantic Web such as RDF, OWL and SPARQL and seen the importance of collaboration of ontologies in the semantic description of multimedia resources, we also present the technique of concepts connection allowing to extend an initial ontology.

    The conceptual step in the pervasive adaptation system is mostly aimed at the success of such a system. It is for this reason that the development of a conceptual adaptation system helps developers to implement their adaptation systems. Accordingly, several categories of contextual information can be presented in a pervasive information system; as such, the network context, the location context, the service context, the application context, the device context, and the person context. Again, a detailed description of each of these contextual information categories allows achieving a better adaptation of the applications to the contexts of use. However, the device context shows the focal point of any information system. In fact, the adaptation of the pervasive information systems, when using contexts, rests on the existing physical constraints in this context. In this paper, we present the architecture of adapting the applications to the pervasive system based on the semantic web serv...

    In this paper, we present a new variant to show results of information retrieval process. Search results proposed here are in the form of textual abstract instead of returning a list of links pointing to relevant web documents. Our current work materializes collaboration between two independent axes: Semantic Web and Fuzzy Logic. The automatic abstract generation represents an extension of our previous works aimed to create an information retrieval system dedicated for kids.

    The technique of adapting the web service allows the user to establish reusable, interoperable, flexible and context-aware applications. In fact, the pervasive system specification is provided by the context-aware applications since it is dynamically adapted. Furthermore, we seek to offer a dynamic description of the web services. This objective, however, can be achieved by adding contextual information structures to the web service description. In the literature, more research works strive to combine the contextual description with the web service description using the OWL-S structure.In fact, the main objective of this paper is to propose structures with two levels for the contextual description of the pervasive system. This description is based on the generic model for the pervasive system design. We, also, suggest integrating such a description into the OWL-S structure.

    With the great mass of the pages managed through the world, and especially with the advent of the Web, it has become more difficult to find the relevant pages after an interrogation. Furthermore, the manual filtering of the indexed Web pages is a laborious task. A new filtering method of the annotated Web pages (by our semantic annotation process) and the non-annotated Web pages (retrieved from search engine “Google”) is then necessary to group the relevant Web pages for the user. In this paper, the authors will first synthesize their previous work of the semantic annotation of Web pages. Then, they will define a new filtering method based on three activities. The authors will also present their querying and filtering component of Web pages; their purpose is to demonstrate the feasibility of the filtering method. Finally, the authors will present an evaluation of this component, which has proved its performance for multiple domains.

    PurposeOne of the open questions is how to ensure the conceptual adaptation in the pervasive system. To answer this question, the authors needed to propose a generic model and a mechanism to describe this system and also need generic and semantic rules to ensure the adaptation. This paper aims to propose a model to describe the pervasive information system. Second, the authors suggest an approach to divide this model so as to describe each category of contextual information separately and ensure the adaptation in the pervasive system. Finally, the authors present examples of semantic rules executed in the pervasive system.Design/methodology/approachThis paper proposes an approach to ensure the conceptual adaptation in the pervasive system. To do it, the authors proposed a model to design the pervasive system and used semantic Web services. They proposed to divide the model to six descriptions related to the pervasive system categories information.FindingsPervasive information system...

    Initially, a significant number of contextual information can be employed to describe the pervasive system. Hence, to design this type of system, there is a stern need for a new information system. Unlike the classical information system, the new system integrates the mobile devices characterized by different hardware and software capacity and other useful devices. Therefore, most pervasive information system designers provide mechanisms and architectures to effectively save, recover and submit the most relevant information to the user regardless of location, time and the user's equipment which are independent of the network constraints. In this paper, the authors present a model to describe the pervasive information system through the use of the existing contextual models. In the same context, they suggest a semantic description to adapt the users to six categories of contextual information by taking the semantic-web-service creation as a basis. Finally, they present the semant...

    In this paper, the authors present an overall description of their information retrieval system which makes a practical collaboration between Semantic Web and Fuzzy logic in order to have profit from their advantages in the information retrieval domain. Their system is dedicated for kids, for this reason the semantic/fuzzy collaboration materialized must be in the background of the information retrieval process because such category of users cannot certainly control semantic web technologies neither fuzzy logic commands. In this paper, the authors present the different services proposed by their system and how they use Semantic Web and Fuzzy logic to develop it. Evaluation tests of the system using universal measures show clearly its efficiency.

    The semantic Web is an infrastructure that enables the interchange, the integration and the reasoning about information on the Web. In our annotation approach, we have proposed metadata of the semantic and fuzzy annotation in RDF to describe pages in a semantic Web environment. Our annotation of a page represents an enhancement of the first result of annotation done by the “Semantic Radar” Plug-in on the page. Now, we want to achieve a semantic and fuzzy interrogation of the annotated Web pages in order to improve the interrogation results for the domain experts. We propose in this paper a new editor named “Sem-SPARQL Editor”, which is based on the SPARQL language, to query the semantic and fuzzy annotations in RDF of pages.

    It is well known that thesaurus cover a large amount of information dedicated for a specific domain and allows different manipulation made by normal users. But, it allows less semantic interpretation for automatic agent than ontologies. In this paper we propose an automatic generation of an OWL ontology based on Roget's Thesaurus of English Words and Phrases in order to use it in our semantic information retrieval system.

    In this paper, we present an approach which aims to facilitate information retrieval for kids by proposing simplest documents first of all in the results lists. A simple document is a concise and non exhaustive document focusing mainly on the user queries' terms. In order to valorize such documents, we propose a valorization process which allows adding a specific value to a score relevance of a document referring to its nature and the user age. The added value could be negative (penalizing therefore long and detailed documents) or positive enhancing therefore the score relevance of documents concentrating on the user query. To get a flexible valorization value, we apply some fuzzy rules.

    In this paper, we present a new variant of our information retrieval process. This variant is characterized by its simplicity and efficiency : the querying pre-treatment covers the document annotation and the ontology enrichment, the querying post-treatment covers relevant document valorisation and the query extension in order to get a more dedicated search attempt.

    This position paper proposes a collaboration method between Seman-tic Web and Fuzzy Logic aiming to handle uncertainty in the information re-trieval process in order to cover more relevant items in result of search process. The collaboration method employs OWL ontology in query enhancement, RDF in annotation process and fuzzy rules in ranking enhancement.

    In this short paper we present three methods to valorise score relevance of some documents basing on their characteristics in order to enhance their ranking. Our framework is an information retrieval system dedicated to children. The valorisation methods aim to increase the relevance score of some documents by an additional value which is proportional to the number of multimedia objects included, the number of objects linked to the user particulars and the included topics. All of the three valorization methods use fuzzy rules to identify the valorization value.

    We propose here a novel approach for extracting hidden semantic from semi-structured data resources and transformed to RDF triples, to be queried through semantic query languages. Unlike existing approaches that only explore the structure or use ontologies, we present a system that allows us to utilize all available information. Our approach constructs a semantically related data from XML represented in RDF via “semantic network” described here. These data could be queried by SPARQL/XQUERY or both simultaneously in multimodal way to perform a semantic search on a set of multimedia news resources.

    Audiovisual documents provide a wide range of content description through more descriptors from different media types. Indeed, the extraction of these descriptions has received an increasing attention. But, the lack of semantic description always persists. In fact, this lack affects the retrieval process. To address this problem, this paper describes an automatic and semantic description of cinematic audiovisual documents. This description is based not only on the audiovisual flux in this post-production phase but also in the documentation in the pre-production phase by using textual and visual modalities. In this context, to extract content description, we find it is essential to extract texts superposed in the image. This process is mainly based on the neural network classifier. Moreover, an effective OCR (Tesseract) is adapted for texts recognition. Experiments results confirmed the interesting performance through two databases, namely, “ICDAR 2011” and our own created database f...

But with the great mass of pages managed through the world, and especially with the advent of the Web, their manual annotation is impossible. In this paper we will focus on the semi-automatic annotation of the Web pages, we will propose an approach and a framework for semantic annotation of Web pages entitled “Querying Web”. Our solution is based on the enriched domain ontologies and on the analysis of the RDF result by the “Semantic Radar” plug-in. We will also present in this paper an evaluation of the automation made by our framework.

    ABSTRACT Identifying the Genre of an audiovisual document is among the major challenges for multimedia retrieval. Indeed, the lack of semantic metadata extraction makes these resources underused in the retrieval process. To overcome these difficulties, the extraction of semantic descriptions requires an analysis of the audiovisual document's content. The automation of the process of describing audiovisual documents is essential because of the richness and the diversity of the available analytical criteria. In this paper, we present a method that allows the identification of a semantic and automatic description from the content such as genre. We chose to describe the cinematic audiovisual documents based on the documentation prepared in the pre-production phase of films, namely synopsis. The experimental result on Imdb (Internet Movie Database) and the Wikipedia encyclopedia indicate that our method of genre detection is better than the result of these corpuses.

    ABSTRACT The description of an audiovisual document represents a major challenge for multimedia retrieval. Indeed, the lack of descriptive metadata extraction makes these proliferated resources underused in the querying process. To overcome these difficulties, the extraction of the semantic metadata of the content and the different structures of an audiovisual document is required. In this paper, we present a method that enables an automatic description of audiovisual documents. This automatic process is mainly based on the use of a multitude of modalities for the description and modeling of audiovisual documents, the standardization of these descriptions in the MPEG-7 standard through its description definition language (DDL) and on the use of semantic web language to link between the audiovisual resources.

    Considerant un document multimedia comme semi-structure (a structure irreguliere, inconnue a priori, pouvant eventuellement etre « partiellement » elicitee), nous proposons de formaliser les differentes caracteristiques extraites a partir de l'analyse des contenus sous forme de metadonnees. Ces metadonnees sont structurees en « metadocuments » qui viendront enrichir la description des documents initiaux. L'objectif est de (re)construire de facon dynamique des documents repondant aux besoins des utilisateurs. Afin d'assurer homogeneite et coherence globale dans la reingenierie de telles collections de document, nous avons decide de travailler sur la base d'une methodologie de conception d'applications hypermedias, OOHDM. Notre proposition a ce niveau consiste a etendre cette methodologie par l'integration des metadonnees dans les differentes etapes, a savoir: la conception des applications, des schemas, des contextes de navigation, et de l'interface. Les metadonnees, considerees comme toute autre donnee du document, doivent pouvoir etre affichees et utilisees lors de l'interrogation des documents.

    With the great mass of pages managed through the world, and especially with the advent of the Web, their manual annotation is impossible. We focus in this paper on the semi-automatic annotation of the Web pages. We propose an approach and a framework for semantic annotation of Web pages entitled “Querying Web”. Our solution is an enhancement of the first result of annotation done by the “Semantic Radar” Plug-in on the Web resources, by annotations using an enriched domain ontology. The concepts of the result of Semantic Radar may be connected to several terms of the ontology, but connections may be uncertain. We represent annotations as possibility distributions. We use the hierarchy defined in the ontology to compute degrees of possibilities. We want to achieve an automation of the fuzzy semantic annotation of Web resources.

    The aim of this paper is to present a solution to cope with the problem of multimedia documents annotation in order to enable user's queries, based on content mining and structure eliciting from semi-structured documents. Whatever the media type, indexing aims at locating spatial and/or temporal (physical) segments. These segments correspond to strings of variable granularity. Their location requires relative or absolute addressing mechanisms, according to the context, as the finite co-ordinate space locator (fcs) in HyTime. Our approach relies on the availability of annotated metadata representing segment content and structure as well as segment transcripts (speech-to-text, closed caption). The available indexing and segmentation tools and techniques make it possible to build describers by eliciting the specific structure of each segment. The aim of this process is to propose a generic view of these specific structures, homogenizing them by combining the different media descri...
