    eCodicology: The Computer and the Mediaeval Library

    No full text
    Through digitisation a large amount of mediaeval manuscript collection became publicly available, but the resources in time and human attention have not grown in proportion of digitised sources. Therefore, the question arises whether the computer can help to evaluate larger amounts of material like this. The project eCodicology has focused its research on the detection and measuring of the different layout features by using methods of pattern recognition for further analyses. The present paper gives insights into the developed software, SWATI – the Software Workflow for the Automatic Tagging of Images, and CodiVis, a visualisation framework for high-dimensional data sets, and how it can help the codicologist to explore the massive amount of heterogeneous datasets. The paper also focusses the various challenges, such as uncertain data due to irregularities and missing information in the manuscript’s catalogues, as well as the accuracy of the image processing results

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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

    Phenetic Approach to Script Evolution

    No full text
    Computational palaeography, as a branch of applied computer science, investigates the evolution of graphemes, explores relationships between scripts, and provides support for deciphering ancient inscriptions, among others. The author applied methods often used to describe evolutionary processes in phylogenetics to analyse the development of scripts. Unlike in the clear evolution of phylogenetics, graphemes used to describe the evolution of scripts are sometimes indistinguishable from their glyph variants. Moreover, the historical background is at times incomplete. In order to reduce uncertainty, the author developed an exploratory data analysis method that combines phenetic analysis methods with a cladistic approach. The paper details the tests the author developed to explore the relationships among 66 different scripts with 186 different features. To extract data for analysis required determining the similarity groups of glyphs and orthographical rules in different scripts; the input is data from humanities-based palaeography. Creation of the similarity groups of the glyphs is based on minimizing the differences between the topological properties of the glyphs and individual decisions in order to avoid homoplasies, as well as the erroneous omission of slightly differing but otherwise related glyphs. For the second purpose, the layered grapheme model and the concept of characteristic transformations of related glyphs were used. Based on the extracted features of the scripts, various machine-learning methods were applied, including multidimensional scaling, k- means partitional clustering, and various hierarchical clustering methods. These algorithms produced similar results, represented in two- and three-dimensional scatter plots and phenograms, which visualize the relationship between the scripts. These results roughly concur with the results of humanities-based palaeography; however, new conclusions can be also derived, including the introduction of the concept of witness scripts, and glyph- and grapheme- level reticulations, which are used to describe the possible relationship of graphemes and scripts. The presented results demonstrate the usefulness of a developed modified phenetic method in exploring the similarities of scripts, and based on the results obtained, some improvements in modelling the distribution of certain historical scripts were also proposed

    Dispelling the Myths Behind First-author Citation Counts

    We 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
