A model-based approach to address the design of Web 2.0
No full textCreating an interactive application based on pre-existing
functionalities poses a number of novel issues in the design
process. We discuss a method, associated with a new model-based
language and a supporting tool, which aims to address such issues
in multi-device contexts. One specific aspect of this method is the
possibility of supporting composition of user interfaces associated
with different services. In addition, the possibility to specify
dynamic user interfaces, Web services accesses and scripts allows
designers to declaratively describe Rich Internet Applications as
well
MARIA: A universal, declarative, multiple abstraction-level language for service-oriented applications in ubiquitous environments
No full textOne important evolution in software applications is the spread of service-oriented architectures
in ubiquitous environments. Such environments are characterized by a wide set of interactive
devices, with interactive applications that exploit a number of functionalities developed beforehand
and encapsulated in Web services. In this article, we discuss how a novel model-based UIDL can
provide useful support both at design and runtime for these types of applications. Web service
annotations can also be exploited for providing hints for user interface development at design time.
At runtime the language is exploited to support dynamic generation of user interfaces adapted to
the different devices at hand during the user interface migration process, which is particularly
important in ubiquitous environment
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
UbiCicero: a location-aware, multi-device museum guide.
No full textIn this paper, we propose UbiCicero, a multi-device, location-aware museum guide able to opportunistically
exploit large screens when users are nearby. Various types of games are included in addition to the
museum and artwork descriptions. The mobile guide is equipped with an RFID reader, which detects
nearby tagged artworks. By taking into account context-dependent information, including the current
user position and behaviour history, as well as the type of device available, more personalised and relevant
information is provided to the user, enabling a richer overall experience. We also present example
applications of this solution and then discuss the results of first empirical tests performed to evaluate the
usefulness and usability of the enhanced multi-device guid
How to exploit abstract user interfaces in MARIA
No full textIn model-based approaches, Abstract User Interfaces enable the specification of interactive applications in a modality-independent manner, which is then often used for authoring multi-device interactive applications. In this paper we discuss two solutions for exploiting abstract UIs. We consider the MARIA language for such comparison. The overall aim is to improve the efficiency of the model-based process, thus making it easier to adopt and apply
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Designing usable applications based on web services
No full textOne trend in software development is to implement application
functionalities through Web services. This eases the possibility of
developing interactive applications exploiting functionalities
implemented by others. In this paper we discuss the issues raised
when designing user interfaces for these types of applications. In
particular, we describe a possible approach to address them based
on the use of model-based user interface descriptions with the
possibility of obtaining versions adapted to different types of
interactive devices. The development of the final user interface is
supported by a semi-automatic process in which at first the
designers take benefit of an authoring tool able to automatically
generate the first version of the user interface and then, after an
evaluation phase of of the resulting user interface, they can
manually make further modifications and refinements in order to
obtain highly usable user interfaces
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
