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)
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)
Business Process 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 may bring many advantages, that go from the possibility of applying advanced reasoning techniques, aimed at the identification of(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)
Sign languages are visual languages used in deaf communities. They are essentially tempo-spatial languages: signs are made of manual components, e.g., the hand movements, and non-manual components, e.g., facial expressions. The e-LIS project aims at the creation of the first web bidirectional dictionary for Italian sign language–verbal Italian. Whereas the(More)

In this paper we describe the usability evaluation experiments of the Query tool system done in the context of the SEWASIE (SEmantic Webs and AgentS in Integrated Economies) project. The usability evaluation is an important step of the User-Centered Design Methodology, followed to develop the SEWASIE system. This European IST project aims at enabling a(More)
