Portuguese corpora of the 18th century: old Medicine texts for teaching and research
Get PDFThe aim of this paper is to demonstrate the application of the methodologies of Corpus Linguistics and of the Natural Language Processing (NLP) tools to an 18th century medicine book. The general objective of this work is to apply the digital humanities tools to a text that has not yet received this kind of approach, in view of teaching an research activities
Effects of Relationship Goals on Linguistic Behavior in Online Dating Profiles:A Classifier Approach
No full textGoing 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
Identifying Parties in Manifestos and Parliament Speeches
No full textThis paper addresses differences in the word use of two left-winged and two right-winged Danish parties, and how these differences,which reflect some of the basic stances of the parties, can be used to automatically identify the party of politicians from their speeches.In the first study, the most frequent and characteristic lemmas in the manifestos of the political parties as well as their languagecomplexity are analysed. The analysis shows inter alia that the most frequently occurring lemmas in the manifestos reflect eitherthe ideology or the position of the parties towards specific subjects, confirming for Danish preceding studies of English and Germanmanifestos. Successively, we scaled our analysis applying NLP methods to the transcribed speeches by members of the same partiesin the Parliament (Hansards) and trained machine learning algorithms in order to determine to what extent it is possible to predict the party of the politicians from the speeches. The speeches are a subset of the Danish Parliament corpus 2009–2017. The best results of the classification experiments gave a weighted F1-score of 0.57. These results are significantly better than the results obtained by the majority classifier (weighted F1-score = 0.11) and by chance results. They show that the party of the politicians can be distinguished from their speeches in nearly 60% of the cases, even if they debate about the same subjects and thus often use the same terminology. In the future, we will include the subject of the speeches in the prediction experiments
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
The development of DOTI (Data of Oral Teletandem Interaction)
Get PDFTeletandem1 (Telles and Vassallo, 2006) is a Voice Over Internet Protocol
(VoIP) communicative activity in which two speakers are involved, each of
whom is an expert in one language and who wishes to learn the language of
the interlocutor. “Virtual meetings” which last one hour are organized weekly;
students speak half of the time in their L1, and the other half in the L2. Teletandem
is also a growing field of research, and the related data, collected by
video-recording the conversations between two participants, are an interesting
resource for analysing communication and learning processes. In order to build
a databank (DOTI – Data of Oral Teletandem Interactions), we collected data
from Sao Paolo State University at São José do Rio Preto (Brazil: languages
Portuguese/English), and from the University of Salento (Italy: languages Italian/
English). DOTI is currently composed of about 700 hours of video data
from, oral teletandem sessions. The current paper describes: i) the state of the
art with regard to developing a databank with video recorded oral sessions, as
well as chat conversations; ii) teletandem as an interaction space; iii) different
learning scenarios and microtasks that might influence the type of data and, in
turn, metadata, in this context
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
