Article
The rapid increase in the number of Earth Observation (EO) systems generates a massive amount of heterogeneous data. It has raised big issues in collecting, preprocessing, storing, and the visualization these data. However, traditional techniques are facing serious challenges when dealing with big EO data dimensions (i.e., Volume, Veracity, Variety...
Conference Paper
The increasing amount of data generated by earth observation missions like Copernicus, NASA Earth Data, and climate stations is overwhelming. Every day, terabytes of data are collected from these resources for different environment applications. Thus, this massive amount of data should be effectively managed and processed to support decision-makers...

Article
The recent proliferation of social networks as a main source of information and interaction has led to a huge expansion of automatic e-recruitment systems and by consequence the multiplication of web channels (job boards) that are dedicated to job offers disseminating. In a strategic and economic context where cost control is fundamental, it has be...
Conference Paper
A growing number of highly optimized reasoning algorithms have been developed to allow inference tasks on expressive ontology languages such as OWL(DL). Nevertheless, there is broad agreement that a reasoner could be optimized for some, but not all the ontologies. This particular fact makes it hard to select the best performing reasoner to handle a...
Article
Our understanding of an application domain evolves over time. If we consider an ontology as a set of semantic constraints which describes our understanding of an application domain, ontologies must be revised. Indeed, adding a new semantic constraint to an ontology may make it inconsistent. To restore consistency with minimal loss of semantics, we...
Conference Paper
In this paper, we present a new architecture of learning path generation and managing the learner’s progression in multi-users context. By “multi-users context”, we hint at real time collaboration between different learners in a hyper-dynamic world; moreover, the architecture allows us to take into account the preceding learners’ appreciations abou...

Our understanding of an application domain evolves over time. If we consider an ontology as a set of semantic constraints which describes our understanding of an application domain, it is needed to revise ontologies. However, adding a new semantic constraint to an ontology may make it inconsistent. To restore consistency with minimal loss of semant...
Conference Paper
Over the last decade, several ontology reasoners have been proposed to overcome the computational complexity of inference tasks on expressive ontology languages. Nevertheless, it is well-accepted that there is no outstanding reasoner that can outperform in all input ontologies. Thus, an algorithm selection problem have emerged in this field of stud...

Conference Paper
Over the last decade, several ontology reasoners have been proposed to overcome the computational complexity of inference tasks on expressive ontology languages such as OWL 2 DL. Nevertheless, it is well-accepted that there is no outstanding reasoner that can outperform in all input ontologies. Thus, deciding the most suitable reasoner for an ontol...
Conference Paper
Full-text available
Semantics-based applications encapsulate commonly a set of ontologies which represent knowledge formalized from different data sources. Some of these ontologies may change over time since, not only data would be updated but also our understanding on application domain would evolve. To ensure that ontologies remain usable, it is needed to revise ont...

Poster
Full-text available
A poster summarizing our research work about predicting the future performances of reasoners given an input ontology. Our main claim is that the output quality of a reasoner is closely depending on the quality of the input, i.e. the ontology. We also claim that machine learning (ML) techniques and more specifically the supervised learning can help...
Conference Paper

In the last decades, many measures and metrics have been proposed with the goal of automatically providing quantitative rather than qualitative indications over researchers' academic productions. However, when evaluating a researcher, most of the commonly-applied measures do not consider one of the key aspect of every research work: the collaborati...

DRAOn is a distributed reasoner which offers inference services for a network of OWL ontologies correlated by alignments. Reasoning with such networks of ontologies depends on the semantics we define for alignments with respect to ontologies. DRAOn supports two semantics for a network of ontologies: the standard Description Logics (DL) semantics fo...
