CS IQP with Neil Heffernan: Using ASSISTments to Help Teachers Recover COVID19-Related Learning Loss
No full textThe COVID pandemic hit heavily on all areas of industries, especially on education. Professor Neil Heffernan, also the founder of ASSISTments, enlisted our help to recoup the loss that occurred during the pandemic. ASSISTmentsis a tool for both teachers and students to use and improve their efficiency. Teachers can easily assign homework and analyze students' performance or learning experience, where students can have an easier time understanding the topic by getting prompt feedback from ASSESSments. Our team aims to make this process even more efficient on the teacher's side by providing a tool to predict the score of a student’s answer and give suggestions for comments. We worked on the training of NLP models that would be deployed into classrooms closely after the end of this project. The NLP model aims to give better and more accurate scores and comments suggestions to teachers. The Bert transformer method is used in this NLP model. We also looked into methods of data parsing and other model ensembles to compare with the models we plan to deplo

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
