XQuery adaptation for multimodal retrieval of multimedia documents

Rather than monotonous, single-modal information, users would like to have a multimodal system to query multimedia documents. In this paper, we present our propositions in two parts, the first part consist on a conceptual model to define semantic relations between multimedia documents. The second part defines an extension of XQuery language to support multimodal querying.

Metadata is essentially static and may be associated with, or embedded in, the multimedia contents. The aim of this paper is to present a proposal for multimedia documents annotation, based on modeling and unifying features elicited from content and structure mining. Our approach relies on the availability of annotated metadata representing segment content and structure as well as segment transcripts. Temporal and spatial operators are also taken into account when annotating documents. Any feature is identified into a descriptor called "meta-document". These meta-documents are the basis of querying by adapted query languages.

This solution is based on a document warehouse enriched by metadata (for each media type) elicited, modeled and structured in meta-documents.

Automatic identification Genre of audiovisual documents

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&#39;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.

Several encouraging attempts at developing methods for searching data have been proposed. However, efficiency and simplicity are still a barrier for further development. This paper gives a global idea about our multimodal system for retrieval multimedia annotated documents. This system combines four retrieval modalities: first by keywords, second by visual graph, third Query by Resources and finally using standardized languages.

Towards a Semantic Multi-modalities Description of Audiovisual Documents

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.

Faced with these huge quantities produced every day, the lack of significant descriptions without missing the important content arises. The extraction of these descriptions requires an analysis of the audiovisual document&#39;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 extraction of a semantic and automatic description from the content such as genre. We chose to describe 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.

The generic model for pervasive information system

However, the pervasive computing introduces a variety of software, hardware and users engineering challenges. The pervasive computing modeling is a new research area. Indeed, we are interested in purposing methodology for modeling pervasive systems. This paper provides an overview of proposed generic model of pervasive information system. Also, we propose an instantiation process to validate this generic model. This purposed generic model represents the highest level of abstraction. It presents only the general concepts of pervasive system.

In this paper we describe an approach for data-driven workflow process modeling. Based on structured tokens Petri Net, the resulting workflow model can represent both control flow and shared data in the workflow process. Besides, to prove our modeling approach, we implement the Opus workflow management system. It provides a graphical editor to model a customize workflow process, and a workflow engine to automatically execute the modeled workflow process.

Our solution is directed towards analysing the ways to "bridge the gap" between physical and semantic levels, for multimedia document modelling and querying. Our goal is to describe how to model and unify features elicited from content and structure mining. These descriptors are built from the various features elicited from the multimedia documents using available processing techniques. The personalization enables dynamic re-structuring and reconstruction of hypermedia documents answering to the user queries. However, more factors should be considered in handling hypermedia documents. Once queried, documents can be adapted by using an indexing scheme, which exploits multiple structures. We can process queries efficiently with minimal storage overhead. We suggest for that, the adaptation of multimedia document content with user needs and preferences. This approach is based on the OOHDM methodology extension with the use of the metadata.

The increase in the use of XML in many applicative domains induces a strong need for providing XML query capabilities to many users. In this paper, we propose a solution of XML graphical querying based on the XQuery language. In our approach, we propose to integrate textual, spatial and temporal meta-data in order to improve information retrieve and present document suitable to the user's needs. We, also, propose the extension of the XQuery by new operators in XQuery grammar to facilitate the use of the meta-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...

PRE-RANKING DOCUMENTS VALORIZATION IN THE INFORMATION RETRIEVAL PROCESS

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.
