Recommender Systems require specific datasets to evaluate their approach. They do not require the same information: descriptions of users or items or users interactions may be necessary, which is not gathered in today datasets. In this paper, we provide a dataset containing reviews from users on items, trust values between users, items category, categories(More)
XlML semi-structured documents provide a flexible and natural way to capture data. More often, users exchange documents with others or reuse their data in a wide range of tasks. A direct consequence is a growing need to manage semi-structured documents and to gain conventional database functionality. The aim of our research I S the development of a(More)
— The SECAS Project (Simple Environment for Context Aware Systems) deals with the adaptation of applications to the context (user preferences and environment, terminal, etc.). We aim to develop a platform which makes the services, data and the user interface of applications adaptable to different context situations. In this domain, researches have(More)
The SECAS Project (Simple Environment for Context Aware Systems) is interested in the adaptation of applications to the context (preferences and environment of the user, used terminal ...). We aim to develop a platform which makes the data, the services and the user interface of applications adaptable to the various context situations. In this domain,(More)
End-users information capture remains a sensitive challenge, especially when information is under the form of documents. The difficulty concerns information indexing so that information can be precisely queried. In the DRUID project, the end-user captures XML paragraph-centric documents (i.e. documents with tags delimiting narrative text paragraphs), and a(More)
Querying non-conventional data is recognized as a major issue in new environments and applications such as those occurring in pervasive computing. A key issue is the ability to query data, streams and services in a declarative way. Our overall objective is to make the development of pervasive applications easier through database principles. In this paper,(More)
This article presents a new way to manage computerized medical records, based on a totally-hypermedia system. As a matter of fact, the classical use of a database limits the necessary variability of the medical record, in function of both the patient profile and the care practitioner habits. The system we propose is based on a hospital Intranet, and on the(More)
Recognition of patterns and prediction of future events has become quite important in many application areas of Complex Event Processing (CEP). However, the state-of-art technologies cannot cope with the heterogeneity of event streams and employ historical and future events to predict new situations. Emerging applications like Prosumer-Oriented SmartGrid(More)
