Software engineering for large-scale multi-agent systems
No full textObjects and agents are abstractions that exhibit points of similarity, but the development of agent-based software poses other challenges to software engineering since software agents are inherently more complex entities. In addition, a large-scale multi-agent system needs to satisfy multiple stringent requirements such as reliability, security, interoperability, scalability, reusability, and maintainability, This workshop brought together researchers and practitioners to discuss the current state and future direction of research in software engineering for large-scale multi agent systems. A particular interest was to understand those issues in the agent technology that difficult and/or improve the production of large-scale distributed systems
Jaelson Castro, Closing the Gap Between Organizational Fernanda Alencar and Gilberto Cysneiros Requirements and Object Oriented Modeling Closing the GAP Between Organizational Requirements and Object Oriented Or ented Modeling
No full textAbstract Requirements Engineering has been considered a key activity in any Software Engineering process. It is well known that a requirements specification should include not only software specifications but also business models and other kinds of information describing the context in which the intended system will function. In recent years we have observed a growing influence of the object-orientation paradigm. Unfortunately, the current dominant object oriented modeling technique, i.e. Unified Modeling Technique, is ill equipped for modeling early requirements which are typically informal and often focus on Organizational objectives. UML is more suitable for later phases of requirements capture, which usually focus on completeness, consistency, and automated verification of functional requirements for the new system. In this paper, we present some guidelines for the integration of early and late requirements specifications. For the organizational modeling we use the i * framework, which focuses on the description of organizational relationships among various organizational actors, as well as an understanding of the rationale for the alternatives chosen. For the functional requirements specification, we rely on a precise subset of the Unified Modeling Language annotated with constraints described in the Object Constraint Language. A small example is used to illustrate how the requirements process iterates between the early and late requirements specification
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Dealing with complexity using conceptual models based on Tropos
No full textSince its establishment, the major objective of the Tropos methodology has been to develop an approach for the systematic engineering of agent-oriented information systems. In this chapter we illustrate a number of approaches to deal with complexity, which address different activities in software development and are deemed to be used in combination. We begin with handling complexity at requirements levels. In particular we examine how modularization can be improved using some of Aspect Oriented Software Development Principles. We then examine how model-based testing applied in parallel to requirements analysis and design can support incremental validation and testing of software components, as well as help to clarify ambiguities in requirements. We also look at how Tropos can help to address complexity in social context when making design decisions. Last but not least, we show how to tackle complexity at the process modelling level. We explore iterative development extension to Tropos as well as perspectives taken from software project management. This allows us to deal with the complexity of large real world projects
