Agents for DDD – Back and Forth
No full textDomain-Driven Design (DDD) emerged in the last two decades as an effective approach adopted especially in agile software development to tackle “the complexity at the heart of software”, to quote one of its main mottos. In this paper, we are interested in exploring the bi-directional conceptual interaction between DDD and Agent-Oriented Software Engineering (AOSE)—and the synergies stemming from their fruitful integration
Hypermedia to connect them all: Autonomous hypermedia agents and socio-technical interactions
No full textCurrent standardization efforts of the Web of Things provide a unique opportunity to integrate technologies from the research domain of multiagent systems and the human-computer interaction field that could take us closer to creating intuitively usable distributed artificial intelligence. In this paper, we discuss what bridges are missing between these largely detached research communities: we propose to use the Hypermedia As The Engine Of Application State principle that is at the core of the Web architecture to underpin systems that integrate multiagent planning and acting with semantic technologies and with interoperable mixed reality interfaces. This should enable the creation of highly augmented environments in private as well as commercial and industrial environments where physical and digital things coexist and interact with one another
Experimental Evaluation of Unbalance and Distortion Indicators in Three-Phase Systems with Neutral
No full textThe characterization of three-phase systems with neutral under unbalanced operation in the presence of waveform distortion is a key aspect in the power quality studies. This paper presents the application to a number of real cases of a unified framework providing a set of synthetic indicators capable to explain the individual effects of unbalance and harmonic distortion. The use of specific indicators extending the notion of total harmonic distortion to the case of unbalanced systems, and the notion of unbalance to the systems with distorted waveforms is illustrated and discussed on various sets of data gathered from real-time measurements on office and laboratory feeders and on a photovoltaic system
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
Towards Forward Responsibility in BDI Agents
Full text linkIn this paper, we discuss forward responsibilities in Belief-Desire-Intention agents, that is, responsibilities that can drive future decision-making. We focus on individual rather than global notions of responsibility. Our contributions include: (a) extended operational semantics for responsibility-aware rational agents; (b) hierarchical responsibilities for improving intention selection based on the priorities (i.e., hierarchical level) of a responsibility; and (c) shared responsibilities which allow agents with the same responsibility to update their priority levels (and consequently commit or not to the responsibility) depending on the lack (or surplus) of agents that are currently engaged with it.<br/
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
