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
Markov Model Based Oriya Isolated Speech Recognizer-An Emerging Solution for Visually Impaired Students in School and Public Examination
Get PDFIn this paper we have tried to focus on problems faced by visually impaired students of Orissa in school and public examinations and discussed the emerging solutions to those problems at the end in order to minimize those problems. Assessment plays an important role in the education system for evaluating student’s skill in that area. Assessment can be carried out by allowing students to appear exam in terms objective or non-objective type questions but due to the advantages offered by objective type assessment like offer speedier marking, reduced need for cross marking, greater fairness (reliability), more coverage of the syllabus and finally automate the marking process which enforces examination system to be held as objective rather non-objective type. Therefore, it is mostly implemented in examination system conducted in public or school exams. But it is very regret to mention that this assessment procedure is not well suitable for students those are visually impaired as they are unable to read what they have written or it is not possible to know if the ribbon has run out or if the line spacing is faulty unless the supervisor tells them. These are the main obstacles faced by visually challenged people which lead to disqualification for higher studies that ultimately reason to failure of motto i.e. “Education for All”. In this research study we have considered close ended objective type question. All possible responses of the closed questions are designed such a way that they are mutually exclusive. The closed ended questions are of five types namely fill-in-the-blanks questions, dichotomous questions, ranking scale questions, multiple choice questions and rating scale questions. As all the answers to the above types of questions carry isolated answers, we have developed Oriya isolated speech recognition system which can easily convert isolated answers uttered by visually impaired students to isolated text(isolated speech to isolated text). Hence, visually impaired students can answer the question as normal student because they do not need at all their hand and eyes to respond the answer. As a result of which overcomes the problem faced by visually challenged people to answer the questions without help of keyboard. Oriya isolated recognition system is developed using hidden Markov Model by incorporating1800 isolated Oriya words collected from 30 speakers in training stage. Testing stage is carried out by considering 5 speakers which yields 76.23% word accuracy on seen data and 58.86% on unseen data
Emotion Recognition using Fuzzy K-Means from Oriya Speech
Get PDFCommunication will be intelligible when conveyed message is interpreted in right-minded. Unfortunately, the rightminded interpretation of communicated message is possible for human-human communication but it’s laborious for humanmachine communication. It is due to the inherently blending of non-verbal contents such as emotion in vocal communication which leads to difficulty in human-machine interaction. In this research paper we have performed experiment to recognize emotions like anger, sadness, astonish, fear, happiness and neutral using fuzzy K-Means algorithm from Oriya elicited speech collected from 35 Oriya speaking people aged between 22- 58 years belonging to different provinces of Orissa. We have achieved the accuracy of 65.16% in recognizing above six mentioned emotions by incorporating mean pitch, first two formants, jitter, shimmer and energy as feature vectors for this research work. Emotion recognition has many vivid applications in different domains like call centers, spoken tutoring systems, spoken dialogue research, human-robotic interfaces etc
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
