    Waging war in the fourteenth century

    No full text
    The papers in this special issue exemplify how, through the study of sources beyond the chronicles which have tended to dominate historical writing about fourteenth-century military history in western Europe, we can advance our knowledge on how war was waged by the English - and on some occasions by their enemies too

    Forced Alignment for Understudied Language Varieties: Testing Prosodylab-Aligner with Tongan Data

    No full text
    Linguists engaged in language documentation and sociolinguistics face similar problems when it comes to efficiently processing large corpora of recorded speech. Though field recordings can be collected efficiently, it may take months or years to process the audio for certain types of analysis. Besides transcription, phonetic analysis often requires the time-consuming alignment of transcription to audio. The expense related to this process may limit both the questions researchers can explore and the amount of data they can analyze. Recent advances in speech recognition technology have led to the development of tools to automate time alignment of transcriptions to audio (Evanini, Isard, and Liberman 2009, Goldman 2011, Kisler, Schiel, and Sloetjes 2012, Reddy and Stanford 2015, Rosenfelder 2013). Such automation promises to expedite the process of preparing data for acoustic analysis. Unfortunately, the benefits of auto-alignment have generally been available only to researchers studying majority languages like English, for which large corpora exist and for which acoustic models have been created by large-scale research projects or corporate entities. Prosodylab-Aligner (Gorman, Howell, and Wagner 2011), developed at McGill University and available free of charge, was developed specifically to facilitate automated alignment and segmentation for less-studied languages. It allows researchers to train their own acoustic models using the same audio files for which alignments will be created. Those models can then be used to create Praat Textgrids aligned to those recordings, with boundaries marked at both the word and segment level. Our study tests the use of Prosodylab-Aligner on Tongan field recordings. The results show that automated alignment of recordings of an understudied language is feasible for linguists without programming experience and less time-consuming than traditional manual alignments. For the benefit of others who may wish to use Prosodylab-Aligner for their own research data, the paper also reviews the software, and outlines the steps required to install software components, prepare data files, train acoustic models, and create time-aligned Textgrids. It also provides tips and solutions to problems we encountered along the way. In addition, since field recordings often contain more background noise than the kinds of laboratory recordings Prosodylab-Aligner was designed to use, the paper also presents an analysis (using PraatR (Albin 2014)) of the relative costs and benefits of removing background noise for both training and alignment purposes.

    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
