Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Using SVM for Smart Direct Marketing (SDM): A case of predicting bank customers interested in the Term Deposits
No full textAbstract:
The objective of this study is to reveal how important and necessary it has become to adopt the new methods and technical of Data Mining derived from artificial intelligence (AI), and this in the process of marketing banking products and precisely that of Term Deposit (TD). Therefore, in our research study we adopted the Support Vector Machine (SVM) method, and we succeeded through the process of modeling borrowed by the techniques of Data Mining (DM) to build a model that will allow us to predict the behavior of bank customers toward term deposits, for this the SVM method has been applied on a database of customers of a bank which includes historical responses of customers during a marketing campaign of the product DT.
For the manipulation tool we used, we chose the Python programming language, recognized by its power in modeling and exploiting DM techniques. For the methodology adopted, we started with a pre-treatment and cleaning of the data to keep only the significant explanatory variables and also for any extreme or aberrant variables, subsequently the modeling was carried out by adopting the DM process, at the end of this process we were able to measure the perfection and the level of predictability of our obtained model, thus we obtained the accuracy of 93% using the metric Accuracy, Thus according to the ROC curve we have that AUC=98, this reflects the performance of our obtained model. So, we were able to build a model that will help bankers make decisions in terms of predicting customers interested in the term deposit product.

L’utilisation de la méthode KPV émanant de l’intelligence artificielle pour la prédiction de la solvabilité des clients bancaires
Get PDFLa gestion du risque de crédit est un sujet important pour les banques et les établissements socio-économiques qui recueillent d’énormes quantités de données, dans l’intention de rendre obsolète la mauvaise décision. Dans cet article, nous avons étudié le comportement du classificateur KPV (K plus Proche Voisin) à la prédiction de la solvabilité des clients d’une banque. Ce classificateur serve à trouver la classe d’un nouveau client qui désire obtenir un crédit auprès d’une banque. À cet effet nous avons utilisé une base de données des clients d’une banque qui comporte des clients solvables et non-solvable.
Étant donné que la méthode utilisée relevant des techniques de l’intelligence artificielle, nous avons utilisé le langage Python comme outil de modélisation, par conséquent, nous avons commencé notre processus de modélisation par un prétraitement des données, par la suite nous avons exploré les différents résultats obtenus par les différentes distances, afin que nous puissions choisir la meilleure valeur de K, ensuite nous avons évalué et comparé les différents modèles de prédiction obtenus. Au terme du processus suivi, nous avons pu conclure que le modèle obtenu par la méthod
