The SEWASIE (SEmantic Webs and AgentS in Integrated Economies) project aims at enabling a uniform access to heterogeneous data sources through an integrated ontology. The overall project development strictly follows a user-centred design methodology. Users have been involved from the very beginning and are constantly participating in the design and testing(More)
In this paper, we describe the usability evaluation experiments of an ontology-based Query manager, which is part of the SEWASIE system (SEmantic Webs and AgentS in Integrated Economies). The usability evaluation is an important step of the User-Centered Design Methodology, followed to develop the entire project that aims at enabling a uniform access to(More)
Sign languages are visual-gestural languages developed mainly in deaf communities; their tempo-spatial nature makes it difficult to write them, yet several transcription systems are available for them. Most sign language dictionaries interact with users via a transcription-based interface; thus users need to be expert of that specific transcription system.(More)
Business Process (BP) modeling is constantly acquiring attention in modern enterprises. Today, BP editor tools support modelers in building correct diagrams only from the syntactic point of view. Enriching them with ontologies can bring many advantages as the possibility of applying advanced reasoning techniques, aimed at the identification of(More)
This paper presents a system supporting tuning and evaluation of a Content-Based Image Retrieval (CBIR) engine for <i>vector images</i>, by a graphical interface providing query-by-sketch and query-by-example interaction with query results, and analysis of result quality. Vector images are first modelled as an inertial system and then they are associated(More)
Nowadays, circa 10% of 7-11 olds turn out to be poor comprehenders: they demonstrate text comprehension difficulties, related to inference making, despite proficiency in low-level cognitive skills like word reading. To improve the reading comprehension of these children, TERENCE, a technology enhanced learning project, aims at stimulating inference-making(More)

Sign languages are visual-gestural languages developed mainly in deaf communities; their tempo-spatial nature makes it difficult to write them, yet several transcription systems are available for them. Most sign languages dictionaries interact with their users via a transcriptionbased inteface; thus their users need to be expert of their specific(More)
