A primary issue in the design of interactive art guides is the effort to build them as a synthesis of several cultures and skills concerning content editing, multimedia production, application structuring and interaction design. The communication between the actors of the development process can be boosted by involving the cultural domain experts in the whole life cycle, providing them with proper design environments for extending and modifying the guide structure and content, to refine the initial design without the intervention of computer specialists. We have developed a framework for End-User Development (EUD) of interactive multimedia guides based on experiences in art exhibitions held at Ca' Foscari in the last two years, culminating in the project of a multimedia guide for the François Pinault contemporary art collection at Punta della Dogana in Venice. The guide features dynamically generated tours personalized on the user answers to a set of questions asked during the tour, prepared by a domain expert as part of the guide content. In this paper we present a methodology for designing end-user oriented software environments based on open and portable standards, and discuss the development of a content management systems for domain experts able to generate personalized tours
More and more large repositories of texts which must be automatically processed represent their content through the use of descriptive markup languages. This method has been diffused by the availability of widely adopted standards like SGML and, later, XML, which made possible the definition of specific formats for many kinds of text, from literary texts (TEI) to web pages (XHTML). The markup approach has, however, several noteworthy shortcomings. First, we can encode easily only texts with a strict hierarchical structure while text has often concurrent hierarchies. Then, extra-textual information, like metadata or annotations, can be tied only to the same structure of the text and must be expressed as strings of the markup language. Third, queries and programs for the retrieval and processing of text must be expressed in terms of languages like XQuery [4], in which every document is represented as a tree of nodes; for this reason, in documents where parallel, overlapping structures exists, the complexity of XQuery programs becomes significantly higher.Consider, for instance, a collection of classical lyrics, with the two parallel hierarchies lyric > stanzas > verses > words, and lyric > sentences > words, with title and information about the author for each lyric, and where the text is annotated both with commentary made by different scholars, and with grammatical categories in form of tree-structured data. Such a collection, if represented with markup techniques, would be very complex to create, manage and use, even with sophisticated tools, requiring the development of complex ad-hoc software.To overcome the some of the above limitations partial solutions exist (see for instance [3]), but at the expense of greatly increasing the complexity of the representation through difficult to read markup extensions, like the so-called "milestone" elements. Moreover, markup query languages need to be extended to take these solutions into consideration [1], making even more difficult to access and use such textual collections.In the project "Musisque Deoque. A digital archive of Latin poetry, from its origins to the Italian Renaissance" sponsored by the Italian MIUR, we have built a model and a language to represent repositories of literary texts with any kind of structure, with multiple and scalable annotations, not limited to textual data,
This paper discusses the design and implementation of a system for promoting small towns based on the mash-up of various data sources for personalized mobile access. The positive issues and the open problems are discussed and evaluated in the frame of an experiment made in a region in Northern Italy
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
