Knowledge and learning management in cultural contexts
No full textKnowledge and learning management process in cultural contexts requires the application of methodologies able to create, sustain and share knowledge in a collaborative way through the participation of domain experts. This paper presents a practical learning model, which captures the significance of the cultural assets by means of the use of narrations. A narration is a medium for knowledge transfer being able to recollect and contextualise cultural data according to their historic and anthological meaning. The knowledge system, from which the narration stems, is based on the definition of relationships between a knowledge representation of the cultural domain fitting the conceptual model of the cultural experts and an information domain representation understandable by the machine (modelled by domain ontology). In this way, it is possible to promote a shared accessibility to the cultural knowledge and an enhancement of the collaborative opportunities among domain experts across the sharing of different perspectives

No full textMany modern and contemporary artists and critics agree that art suggests emotions, interpretations, meanings, mediated by the viewer's experience, mood and mind. After the Impressionists' lesson, the question "What does it represent?" may have different answers according to who asks it. Picasso used to say in Picasso on Art: "People who try to explain pictures are usually barking up the wrong tree."
In the world of computers and technological artifacts, emotions and interpretationsmust not supersede the meaning that the designer of an interface, of amessage, of a dialogue has conceived to make an artifact usable and effective.Hence, the Advanced User Interfaces community opposes to Léger, accepts the challenge and tries to propose visual and perceptual interfaces which abstract from housekeeping and technical details, to be concrete and expressive to their users. In front of a visual interface, humans should not only understand the virtual world behind it, but also be empowered, able to be consumers and producers of knowledge through computing, participant to a human collective mind.
The invited speakers of this edition of AVI, the eighth of the series, explore these perspectives from different points of view. Riccardo Rabagliati, Dean of the Venice Academy of Fine Arts, Italy, explores the realm of interactive art, confronting the complementary skills needed to conceive an artwork through new technologies. Gerhard Fischer, Director of the Center for LifeLong Learning and Design (L3D) of the University of Colorado, USA, explores visualization as a dimension of distributed intelligence, seen as an effective framework for understanding what humans can achieve and how artifacts and tools can be designed and evaluated to empower human beings and empower their tasks. Elizabeth Mynatt, Director of the GVU Center at Georgia Institute of Technology, USA, illustrates the nascent relationship between people and computation, driven by the emergence of people as equally, and interchangeably, consumers and producers of the computing experience.
However, the danger to be an inane designer is always present. How to avoid this trap is collectively addressed by 32 full papers (which are one fourth of the submissions in their category), 45 short papers and 10 system papers, demonstrating prototypes and working experiences. They reflect, out of the about 200 papers submitted, variegated experiences brought to Venice by authors of nineteen countries worldwide.
Three satellite workshops have been associated to AVI 2006. BELIV06--Beyond Time and Errors: Novel Evaluation Methods for Information Visualization has been organized by Enrico Bertini and Giuseppe Santucci, Università di Roma "La Sapienza", Italy, and by Catherine Plaisant, University of Maryland, USA. Context in Advanced Interfaces has been organized by Kris Mihalic and Manfred Tscheligi, University of Salzburg, Austria, and by Alexander Braendle and Marco Combetto, Microsoft Research Cambridge, UK. The third workshop, Gender and Interaction: Real and Virtual Women in a Male World, has been organized by Antonella De Angeli, University of Manchester, UK, and by Nadia Bianchi-Berthouze, UCL, UK.
Finally, two tutorials, offered by Mark Maybury, The MITRE Corporation, USA, and by Monique Noirhomme-Fraiture, University of Namur, Belgium, survey the Intelligent Visual Interfaces, and the Statistics for Visual Interface Evaluation
Metareasoning in the determination of image interpretation strategies
No full textFlexible determination of image interpretation strategies is made possible by reasoning on the state of the interpretation process. The state is here described as a string of attributed symbols denoting images, descriptions, actions and patterns of actions. Goals of the interpretation are specified by Conditional Attributed Rewriting Systems. An interpreter exploits these systems to interpret the image, i.e., to determine the evolution of the state from the initial state to the final interpretation. An example from liver biopsy interpretation is introduced, its results constrasted with those of human interpretations and the automatic interpreter efficacy commented on
