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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Exploiting the semantic web for the automatic extraction of Los Angeles city data
Get PDFLAUREA MAGISTRALEL'Integrazione dei Dati è un passaggio fondamentale nello sviluppo di decisioni basate su di essi nelle aziende e nella maturazione da parte dei manager di una certa consapevolezza della loro importanza. Tuttavia, oggi non è così banale praticare tecniche di Integrazione dei Dati a causa dell'esplosione dal fenomeno dei Big Data, le cui conseguenze stanno sfidando il mondo aziendale in ogni ambito, specialmente il tempo di processo richiesto durante lo sviluppo di qualsiasi progetto. Questo lavoro di ricerca propone un tentativo di soluzione a questo problema e di incoraggiamento ad una più elevata efficacia nelle imprese, suggerendo un nuovo approccio per l'identificazione automatica del contenuto di un dataset, ponendo particolare attenzione sulle informazioni mostrate da una delle sue colonne. Questa categorizzazione intelligente è resa possibile grazie all'utilizzo delle informazioni e dalla struttura che contraddistinguono le ontologie, definite sulla base dei principi del Web Semantico, che consiste in una estensione del World Wide Web. Come punto di partenza del progetto, sono stati testati diversi approcci su 41 dataset appartenenti alla città di Los Angeles. Quindi, durante ogni fase di sviluppo, sono stati tracciati tutti i miglioramenti ottenuti fino a generare una metodologia più completa e ampia che si è identificata in un modello finale. Infine, le performance di quest'ultimo sono state esaminate includendo anche nell'analisi, quando possibile, l'utilizzo di ulteriori informazioni dal dataset, come ad esempio la colonna contenente la posizione. I risultati ottenuti dagli esperimenti sui dataset hanno mostrato un significativo miglioramento dell'accuratezza e correttezza delle risposte, dato dallo sviluppo graduale del modello finale.Data Integration is an essential step for developing data-driven decision in companies and for enhancing the awareness in managers towards the importance of information. However, nowadays is not easy to exert it properly due to the explosion of the Big Data phenomenon, of which consequences are affecting every corner of the enterprise, especially the processing time during projects' development. This research study proposes a solution to address this problem and promote effectiveness in companies, i.e. introduce a novel approach to automatically detect the content of a dataset, with a special attention on the information stored in one of its columns. This intelligent categorization is made possible by the exploitation of ontologies knowledge and structure, according to the principles of the Semantic Web, which is an extension of the World Wide Web. As a starting point, we tested several approaches using 41 datasets belonging to the city of Los Angeles. Hence, we tracked the improvements obtained in each step to design a more comprehensive methodology, i.e. the final model. Finally, we investigated the performance of this final model including also, when available, the exploitation of other information in the datasets, such as the location. Experimental results on datasets has shown that the accuracy and correctness of the outcome improved significantly with the development of the final design
