An eXtensible middleware for Multichannel, Multimodal, and Multipattern services (X3M)
No full textIn the Ubiquitous Internet scenario, users increasingly require to customize the ways they access online services and content, by choosing preferred devices (e.g. traditional PCs, PDAs, mobile phones, digital multimedia players), preferred communication channels (e.g. traditional wired or wireless networks, 3G mobile or VoIP infrastructures, DVB streaming media) and preferred interaction patterns (e.g. receiving content by means of explicit user requests or upon reaction to certain events). Traditional multimodal and multichannel support platforms have vertical approaches, lack extensibility and therefore support only limited sets of interaction devices, channels or patterns and often require specific content types (e.g. e-learning). We propose a novel platform for multichannel multimodal and multipattern content/service access that allows integration of different heterogeneous interaction styles and can easily be extended to cope with novel devices, communication channels or interaction pattern

User-Centric Emergency Management: a Disappearing Middleware Approach
No full textIn case of emergency, wireless and wired networks permit to reach people in several different ways with precise information about danger and advices on how to behave. This is possible only by exploiting knowledge about user preferences or requirements, impairments and device features.
Moreover, measurements performed by sensors, peripherals and appliances provide information about user location that can augment the capabilities of traditional emergency management systems.
Device interconnection and pervasive Internet access enable much more effective reactions to crisis or disaster scenarios; anyway, providing location-driven emergency plans on a per-user basis inherently introduces the problems of service orchestration and user profiling, leading to an enormous complexity in this information handling. We claim that simplicity and effectiveness in generating customized emergency plans can derive from the integration of existing emergency management systems with an infrastructure for the support of ubiquitous Internet access that takes care of the whole inherently significant information and relieves most users from any unnecessary detail. The paper also claims that one such middleware can take advantage from a simplification approach that makes its design extremely compact, by playing a role of service coordinator. We propose a middleware architecture approach that delegates responsibility for information processing to external and pluggable services and that overcomes the issue of complexity by composing services into workflow specifications, arranged depending on user profile and needs, while introducing, at the same time, a very limited overhead
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
A user-centric composition model for the Internet of Services
No full textIn the modern Internet of Services scenarios, users need to create, share and access contents and services in extremely personalized ways and by means of heterogeneous devices and interaction channels. The most promising architectural solutions to cope with such dynamic and evergrowing scenario adopt a service oriented approach and leverage service composition platforms to flexibly arrange new value added services made up of basic offtheshelf components.
Though, current solutions for service composition target rather static scenarios and scarcely support today's dynamic Web, where new services and contents continually become available to satisfy novel user needs and service compositions may become obsolete and need reconfiguration.
We propose a novel composition model that aims at being extremely flexible and extensible, yet remaining easily usable by hiding complexity to users
