Due to the large amount of data generated by user interactions on the Web, some companies are currently innovating in the domain of data management by designing their own systems. Many of them are referred to as NoSQL databases, standing for ’Not only SQL’. With their wide adoption will emerge new needs and data integration will certainly be one of them. In(More)
The World Wide Web infrastructure together with its more than 2 billion users enables to store information at a rate that has never been achieved before. This is mainly due to the will of storing almost all end-user interactions performed on some web applications. In order to reply to scalability and availability constraints, many web companies involved in(More)
No SQL stores are emerging as an efficient alternative to relational database management systems in the context of big data. Many actors in this domain consider that to gain a wider adoption, several extensions have to be integrated. Some of them focus on the ways of proposing more schema, supporting adapted declarative query languages and providing(More)
This paper presents the framework to support the interoperability among Semantic Resources1 (SRs) proposed by the FUNSIEC project. FUNSIEC aims at studying the feasibility of building and maintaining an Open Semantic Infrastructure for the European Construction Sector (OSIECS). FUNSIEC adopted a layered approach where the SRs are mapped at the metaschema(More)
This paper investigates Description Logics which allow transitive closure of roles to occur not only in concept inclusion axioms but also in role inclusion axioms. First, we propose a decision procedure for the description logic SHIO+, which is obtained from SHIO by adding transitive closure of roles. Next, we show that SHIO+ has the finite model property(More)
