Metareasoning in the determination of image interpretation strategies
No full textFlexible determination of image interpretation strategies is made possible by reasoning on the state of the interpretation process. The state is here described as a string of attributed symbols denoting images, descriptions, actions and patterns of actions. Goals of the interpretation are specified by Conditional Attributed Rewriting Systems. An interpreter exploits these systems to interpret the image, i.e., to determine the evolution of the state from the initial state to the final interpretation. An example from liver biopsy interpretation is introduced, its results constrasted with those of human interpretations and the automatic interpreter efficacy commented on
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
KNOWLEDGE-BASED CONTEXTUAL RECOGNITION AND SIEVING OF DIGITAL IMAGES
No full textSieves are operators which exploit disciplinary knowledge for a contextual elimination of structures hindering the interpretation of a digital image. A sieve is realized as a conditional attributed Lindenmayer-system with interaction, a generative tool defined in the paper
Cooperative Visual Environments for the Design of Effective Visual Systems
No full textThis paper describes the architecture of cooperative visual environments (CVE). This proposal stems from the findings of several experiments which suggested overcoming the limitations of first-generation user-interface management systems (UIMS) by allowing the users to determine their own computational environment. To avoid user disorientation, as well as the possibility of creating ambiguous or contradictory systems, a novel discipline for the specification and use of the tools is adopted. A systemic approach has been proposed to identify the variables needed to use, observe and adapt a CVE. The design and implementation of tools satisfying this discipline led to the definition of network objects, generalizing composite objects, and to the introduction of typed links allowing a new technique for message passing. The paper illustrates the above points by discussing the rationale behind the design of CVEs, deriving the requirements which CVEs have to satisfy and outlining the architecture with the fundamental mechanisms which allow their use and evolution. The nature of the proposal is also clarified through an example drawn from a real case. © 1993 Academic Press. All rights reserved
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
