Integrating multiple models for definition of IT governance model for banking ITGSM
No full textThe regulations, guidelines and procedures defined to give support to organizations as regards Information Technology play a crucial role when any organization wants to carry out good corporative government. In its quest to ensure the suitable control and management of activities, processes and procedures, the banking sector is currently subject to the implementation and adoption of multiple models and standards. However, there is no single model that provides a unified solution, allowing there to be integrated and overall improvement of the processes used in this context. In our desire to offer a proposal which provides an Information Technology Governance Model for Banking (ITGSM), we have integrated six models which are related to this context; these are: BASEL II, COBIT 4.1, RISK IT, VAL IT, ISO 27 002 and ITIL V.3. We have taken into account the latest versions of the models. Moreover, considering that integration is an essential strategy for supporting the joining of multiple models in harmonization projects, we have defined a process to carry out out this purpose. This research intends to support banking organizations which are interested in introducing new processes, or improving their existing ones in specific areas such as maintaining IT governance, managing the investment of IT, IT risk, managing information security and the life cycle of IT services
Clinical-chatbot AHP evaluation based on “quality in use” of ISO/IEC 25010
Full text linkBackground
Conversational agents are currently a valid alternative to humans in first-level interviews with users who need information, even in-depth, about services or products. In application domains such as health care, this technology can become pervasive only if the perceived ”quality in use” is appropriate. How to measure chatbot quality is an open question. The international standard ISO/IEC 25010 proposes a set of characteristics (effectiveness, efficiency, satisfaction, freedom from risk, and context coverage) to be considered when the ”quality in use” of a software system has to be measured.
Basic procedure
This study proposes a clinical chatbot comparison method based on quality. The proposed approach is based on Analytic Hierarchy Process methodology (AHP).
Findings
Our contribution is twofold. First, we propose a set of measures for each characteristic of ISO/IEC 25010 according to three classes of functionality: providing information, providing prescriptions and process management. Moreover a quantitative method is proposed for making homogeneous the pairwise weights when the AHP is used for the ”quality-in-use” comparison. As a case study, a comparison of two versions of a chatbot was performed.
Conclusions
The results show that the proposed approach provides an effective reference base for performing quality comparisons of medical chatbots compliant with the ISO/IEC 25010 standard
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

Beyond Language Independent Object-Oriented Metrics: Model Independent Metrics
No full textSoftware Metrics have become essential in software engineering for several reasons, among which quality assessment and reengineering. In the context of the European Esprit Pro ject FAMOOS, whose main goal was to provide methodologies for the reengineering of large industrial software systems, we have developed the Moose Reengineering Environment, based on the language independent FAMIX metamodel. Moose includes a metrics engine which supports language independent metrics, since coping with software written in different implementation languages was one of the project's main constraints. Our current research is pushing us towards the development and implementation of a metametamodel, which would include our metamodel and allow for several extension in different research directions, among which concept analysis, knowledge management and software evolution. In this article we want to present our current and future work for the transition from language independent to domain independent metrics
