consumed by third-party applications. The prototype we have developed builds on a web user interface and SPARQL endpoint initially developed to query a single terminological database (Terminesp), now extended to navigate a set of multilingual terminologies. The vocabulary used to represent

The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive

and efficiency gains from such a tight coupling, we identify four key relationships affecting how geographic data (fields and objects) and agent-based process models can interact: identity, causal, temporal and topological. We discuss approaches to implementing tight integration, focusing on a middleware

architectures may be well-suited for transaction processing, however more efficient technologies can be employed for enterprise data integration. In particular, the use of the Linked Data paradigm appears to be a very promising approach. In this article we explore challenges large enterprises are still facing

The TermSciences initiative aims at building a multi-purpose and multi-lingual knowledge system from different source vocabularies produced by major French research institutions and which were initially intended to be used for indexing and cataloguing scientific literature. Since the construction

A fundamental task in data integration and data exchange is the design of schema mappings, that is, high-level declarative specifications of the relationship between two database schemas. Several research prototypes and commercial systems have been developed to facilitate schema-mapping design; a

in this paper: they rely on data and sources presented in the updated version of my trilogy (Castells 2000a). For the sake of clarity, I will rst present the conceptual framework I use in my analysis of social structure. I will then proceed to enumerate the main transformations taking place in social structures

multilingual access to diverse Japanese humanities databases by linking and re-using LOD resources dynamically. It proposes a method, which dynamically generates links across databases using Linked Data when users perform keyword searches. We built a prototype information retrieval system based on LOD

enrichment problem for sensor data. It builds upon Linked Data principles as a valid basis for a unified enrichment infrastructure and proposes a dynamic enrichment approach that sees enrichment as a process driven by situations of interest. The approach is demonstrated through examples and a proof
