Texto completoThe web of data is a huge global data space, relying on semantic web technologies, where a high number of sources are published and interlinked. This data space provides an unprecedented amount of knowledge available for novel applications, but the meaningful usage of its sources is often difficult due to the lack of schema describing the content of these data sources. Several automatic schema discovery approaches have been proposed, but while they provide good quality schemas, their use for massive data sources is a challenge as they rely on costly algorithms. In our work, we are interested in both the scalability and the incrementality of schema discovery approaches for RDF data sources where the schema is incomplete or missing.Furthermore, we extend schema discovery to take into account not only the explicit information provided by a data source, but also the implicit information which can be inferred.Our first contribution consists of a scalable schema discovery approach which extracts the classes describing the content of a massive RDF data source.We have proposed to extract a condensed representation of the source, which will be used as an input to the schema discovery process in order to improve its performances.This representation is a set of patterns, each one representing a combination of properties describing some entities in the dataset. We have also proposed a scalable schema discovery approach relying on a distributed clustering algorithm that forms groups of structurally similar entities representing the classes of the schema.Our second contribution aims at maintaining the generated schema consistent with the data source it describes, as this latter may evolve over time. We propose an incremental schema discovery approach that modifies the set of extracted classes by propagating the changes occurring at the source, in order to keep the schema consistent with its evolutions.Finally, the goal of our third contribution is to extend schema discovery to consider the whole semantics expressed by a data source, which is represented not only by the explicitly declared triples, but also by the ones which can be inferred through reasoning. We propose an extension allowing to take into account all the properties of an entity during schema discovery, represented either by explicit or by implicit triples, which will improve the quality of the generated schema

Texto completoAn increasing number of linked data sources are published on the Web. However, their schema may be incomplete or missing. In addition, data do not necessarily follow their schema. This flexibility for describing the data eases their evolution, but makes their exploitation more complex. In our work, we have proposed an automatic and incremental approach enabling schema discovery from the implicit structure of the data. To complement the description of the types in a schema, we have also proposed an approach for finding the possible versions (patterns) for each of them. It proceeds online without having to download or browse the source. This can be expensive or even impossible because the sources may have some access limitations, either on the query execution time, or on the number of queries.We have also addressed the problem of annotating the types in a schema, which consists in finding a set of labels capturing their meaning. We have proposed annotation algorithms which provide meaningful labels using external knowledge bases. Our approach can be used to find meaningful type labels during schema discovery, and also to enrichthe description of existing types.Finally, we have proposed an approach to evaluate the gap between a data source and itsschema. To this end, we have proposed a setof quality factors and the associated metrics, aswell as a schema extension allowing to reflect the heterogeneity among instances of the sametype. Both factors and schema extension are used to analyze and improve the conformity between a schema and the instances it describes
