A visual paradigm for defining task automation
No full textIn the last years, researchers are devoting many efforts to improve technological aspects of the Internet of Things (IoT), while little attention has dedicated to social and practical sides. Professional developers program the behavior of smart objects. In addition, often the functionality exposed by a single object are not able, alone, to exhaustively support the end users' tasks. The opportunities offered by IoT can be amplified if new highlevel abstractions and interaction paradigms enable also non-technical users to compose the behavior of multiple objects. To fulfill this goal, we present a model to express rules for smart object composition, which includes new operators for defining rules coupling multiple events and conditions exposed by smart objects, and for defining temporal and spatial constraints on rule activation. Such model has been implemented in a Web application whose composition paradigm has been designed during an elicitation study with 25 participants
End-User Development for the Internet of Things: EFESTO and the 5W Composition Paradigm
No full textThis paper illustrates a composition paradigm and a related tool to express rules for smart object composition. The composition paradigm is characterized by operators for coupling multiple events and conditions exposed by smart objects, and for defining temporal and spatial constraints on rule activation. The design of the composition paradigm is based on the results of an elicitation study that involved 25 participants
BPMN Extensions and Semantic Annotation in Public Administration Service Design
No full textPart 2: Model-Based and Model-Driven ApproachesInternational audienceInternet of Things (IoT), and in general the Internet of Everything (IoE), are deeply influencing the business processes Digital Transformation, also in the Public Administration context, introducing new actors and interactions among People, Process, Data and Things. Therefore, a re-design of the processes or the creation of new ones is necessary, in a way that the design of a public service meets needs and skills of different end users (citizens, business managers, experts, etc.). This paper presents a framework for the design of public service user interfaces that, on the basis of domain ontologies and BPMn extensions, support the modeling of new interactions with IoT and bot services, in particular Telegram Bots, in the context of public administration processes. A service semantic annotation model can be shared with and reused by other organizations, thus reducing the user interface design and implementation time, and consequently the overall service development time
Hands-on actionable mashups
No full textThis paper describes how to involve end users without expertise in programming in a session where they will be asked to accomplish some tasks according to a new paradigm for actionable mashups. The goal will be to understand what the advantages of this new paradigm are with respect to traditional methods for mashup composition and information exploration
Making mashups actionable through elastic design principles
No full textThis paper discusses motivations and requirements leading to elastic environments where relevant information and the functions that can be performed on it can be shaped by end users at runtime. As a solution for creating elastic environments, a framework is presented which exploits methods for the mashup of heterogeneous resources and elastic features that permit the easy transition of information between different task contexts according to the recently proposed notion of transformative user experienc

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
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
