Special Issue on the Italian Conference on Computational Logic: CILC 2009
No full textThis special issue of
Fundamenta Informaticae
contains the revised, extended versions of selected
papers presented at the Italian Conference on Computational Logic (Convegno Italiano di Logica Com-
putazionale, CILC’09) which was held at the Engineering Department of the University of Ferrara, Italy.
This conference was the twenty-fourth edition of the Italian national congress of the GULP Associ-
ation (Gruppo Ricercatori e Utenti di Logic Programming) which gathers researchers and users of Logic
Programming. Since the first edition in Genoa in 1986, the GULP Association organizes every year a
scientific meeting to present ideas, tools, and new advances in Computational Logic and related areas,
such as Artificial Intelligence and Deductive Databases. All these areas had a very significant growth
over the last decades and nowadays they all play a crucial role in the fields of Information Processing
and Computer Science.
The CILC’09 meeting was attended by more than fifty people and 28 papers were presented. Out of
those papers, 13 papers were selected and their authors were invited to submit an improved version for
publication in this special issue. After two rounds of careful reviews, where each article was assigned to
at least three reviewers, we finally chose 8 papers which now appear in this present issu
Automatic Proofs of Protocols via Program Transformation.
No full textWe propose a method for the specification and the automated verification of temporal properties of protocols which regulate the activities of multiagent systems. The set of states of those systems may be infinite so that, in general, the verification of a property of a multiagent system cannot be performed by an exhaustive inspection. We specify a given multiagent system by means of a constraint logic program P with locally stratified negation, and we specify a given temporal property to be verified by means of an atomic formula A. In order to verify that the given temporal property holds, we transform the program P into an equivalent program T such that the fact A ← belongs to T. Our transformation method consists of a set of rules and an automatic strategy that guides the application of the rules. Our method is sound for verifying properties of protocols that are expressible in the CTL logic [5]. Although our method is incomplete for proving properties of infinite state systems, it is able to verify important properties of several protocols which are used in practice
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
