Experiments on domain adaptation for patent machine translation in the PLuTO project
Full text linkThe PLUTO1 project (Patent Language Translations Online) aims to provide a rapid solution for the online retrieval and translation of patent documents through the integration of a number of existing state-of-the-art components provided by the project partners. The paper presents some of the experiments on patent domain adaptation of the Machine Translation (MT) systems used in the PLuTO project. The experiments use the International Patent Classification for domain adaptation and are focused on the English–French language pair
Meta-Evaluation of a Diagnostic Quality Metric for Machine Translation
No full textDiagnostic evaluation of machine translation
(MT) is an approach to evaluation that
provides finer-grained information compared
to state-of-the-art automatic metrics.
This paper evaluates DELiC4MT, a diagnostic
metric that assesses the performance
of MT systems on user-defined linguistic
phenomena. We present the results obtained
using this diagnostic metric when
evaluating three MT systems that translate
from English to French, with a comparison
against both human judgements and
a set of representative automatic evaluation
metrics. In addition, as the diagnostic
metric relies on word alignments, the
paper compares the margin of error in diagnostic
evaluation when using automatic
word alignments as opposed to gold standard
manual alignments. We observed that
this diagnostic metric is capable of accurately
reflecting translation quality, can be
used reliably with automatic word alignments
and, in general, correlates well with
automatic metrics and, more importantly,
with human judgements
A Web Application for the Diagnostic Evaluation of Machine Translation over Specific Linguistic Phenomena
No full textThis paper presents a web application and a
web service for the diagnostic evaluation of
Machine Translation (MT). These web-based
tools are built on top of DELiC4MT, an opensource
software package that assesses the performance
of MT systems over user-defined
linguistic phenomena (lexical, morphological,
syntactic and semantic). The advantage of the
web-based scenario is clear; compared to the
standalone tool, the user does not need to carry
out any installation, configuration or maintenance
of the tool
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
Hybrid Example-Based SMT: the Best of Both Worlds?
No full textWay and Gough, 2005) provide an indepth comparison of their Example-Based Machine Translation (EBMT) system with a Statistical Machine Translation (SMT) system constructed from freely available tools. According to a wide variety of automatic evaluation metrics, they demonstrated that their EBMT system outperformed the SMT system by a factor of two to one
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
