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
Arguing On Communicative Goals In Explanations
No full textThis paper describes how we simulate a dialog aimed at resolving conflicts between an Instructing and an Executing Agent in explanation text planning. We describe how the two agents are modelled. We then illustrate the algorithm which, starting from the discovery of a conflict and proceeding through a set of negotiated belief revisions, brings to solve the conflict or to conclude that it cannot be solved. An example in the domain of drug prescription is provided. 1. INTRODUCTION In this paper we consider a particular case of collaborative activity, where an Instructing Agent (IA) has to explain to an Executing Agent (EA) how to perform an action. However, IA's and EA's views about whether to talk about a specific subject can be in conflict: IA might consider irrelevant or inappropriate to talk about subjects which, on the contrary, EA finds interesting, or the inverse. To solve this conflict, the two agents should be able to initiate a dialogue aimed at understanding the reasons of t..
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
Affective natural language generation
No full textThe automatic generation of natural language messages (or NLG) has been em-ployed in many computer systems and for various purposes, which go from pro-viding information on a particular subject, to instructing on how to perform some-complex- action, to arguing about a particular claim (for an overview
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
