Thierry Etchegoyhen, Andoni Azpeitia
2016 Proceedings of the 54th Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers)  
We describe and evaluate a simple method to extract parallel sentences from comparable corpora. The approach, termed STACC, is based on expanded lexical sets and the Jaccard similarity coefficient.  ...  board and gives significantly better results on the noisiest datasets.  ...  We would like to thank MondragonLingua Translation & Communication as coordinator of these projects and the three anonymous reviewers for their helpful feedback and suggestions.  ...

Knowledge-lean projection of coreference chains across languages

Yulia Grishina, Manfred Stede
2015 Proceedings of the Eighth Workshop on Building and Using Comparable Corpora  
We apply a direct projection algorithm on a multi-genre and multilingual corpus (English, German, Russian) to automatically produce coreference annotations for two target languages without exploiting any  ...  Our evaluation of the projected annotations shows promising results, and the error analysis reveals structural differences of referring expressions and coreference chains for the three languages, which  ...  In this paper, we report on experiments with projecting nominal coreference chains across bilingual corpora.  ...

Metrical Tagging in the Wild: Building and Annotating Poetry Corpora with Rhythmic Features [article]

Thomas Haider
2021 arXiv   pre-print
In this work, we provide large poetry corpora for English and German, and annotate prosodic features in smaller corpora to train corpus driven neural models that enable robust large scale analysis.  ...  Poetry corpora do exist for a number of languages, but larger collections lack consistency and are encoded in various standards, while annotated corpora are typically constrained to a particular genre  ...  Acknowledgments We thank Gesine Fuhrmann and Debby Trzeciak for their annotations.  ...

Extracting Parallel Sentences from Comparable Corpora using Document Level Alignment

Jason R. Smith, Chris Quirk, Kristina Toutanova
2010 North American Chapter of the Association for Computational Linguistics  
Results for both accuracy in sentence extraction and downstream improvement in an SMT system are presented.  ...  We also include features which make use of the additional annotation given by Wikipedia, and features using an automatically induced lexicon model.  ...  Experiments Data We annotated twenty Wikipedia article pairs for three language pairs: Spanish-English, Bulgarian-English, and German-English.  ...

A Survey of Available Corpora for Building Data-Driven Dialogue Systems [article]

Iulian Vlad Serban, Ryan Lowe, Peter Henderson, Laurent Charlin, Joelle Pineau
2017 arXiv   pre-print
We also examine methods for transfer learning between datasets and the use of external knowledge. Finally, we discuss appropriate choice of evaluation metrics for the learning objective.  ...  In the area of dialogue systems, the trend is less obvious, and most practical systems are still built through significant engineering and expert knowledge.  ...  Canada Research Chairs, the Canadian Institute for Advanced Research (CIFAR) and Compute Canada.  ...

Building Arabic Corpora: Concepts, Methodologies, Tools, and Experiments

Imad Zeroual, Abdelhak Lakhouaja
2019 Zenodo  
The focus of corpora builders is essentially divided into three areas: corpus compilation, data processing, and corpus annotation.  ...  Corpora are essential resources for computational linguistics and Natural Language Processing (NLP) fields.  ...  As mentioned, Sinclair (2005) formulates the overall instructions proposed by the previous authors in ten fundamental criteria to follow in the design and the compilation of a general corpus:  ...

Negation and Speculation in NLP: A Survey, Corpora, Methods, and Applications

Ahmed Mahany, Heba Khaled, Nouh Sabri Elmitwally, Naif Aljohani, Said Ghoniemy
2022 Applied Sciences  
Many English corpora for various domains are now annotated with negation and speculation; moreover, the availability of annotated corpora in other languages has started to increase.  ...  In this article, we review the corpora annotated with negation and speculation in various natural languages and domains.  ...  This section has explored corpora annotated for negation and speculation in 13 languages from six language families: Germanic languages (English, German, Swedish), Romance (French, Spanish), Uralic (Hungarian  ...

Tailoring and Evaluating the Wikipedia for in-Domain Comparable Corpora Extraction [article]

Cristina España-Bonet, Alberto Barrón-Cedeño, Lluís Màrquez
2020 arXiv   pre-print
We run thorough experiments to assess the quality of the obtained corpora in 10 languages and 743 domains.  ...  We release the WikiTailor toolkit with the implementation of the extraction methods, the evaluation measures and several utilities.  ...  So, for the editions with more articles, we also extract all the articles from a larger sub-tree, and that favours even more the extraction of huge in-domain corpora for English and more modest ones for  ...

Linguistically-Based Comparison of Different Approaches to Building Corpora for Text Simplification: A Case Study on Italian

Dominique Brunato, Felice Dell'Orletta, Giulia Venturi
2022 Frontiers in Psychology  
In this paper, we present an overview of existing parallel corpora for Automatic Text Simplification (ATS) in different languages focusing on the approach adopted for their construction.  ...  To this end, we perform a two-level comparison on Italian corpora, since this is the only language, with the exception of English, for which there are large parallel resources derived through the two approaches  ...  , and German (Suter et al., 2016) .  ...

Generalizing Cross-Document Event Coreference Resolution Across Multiple Corpora

Michael Bugert, Nils Reimers, Iryna Gurevych
2021 Computational Linguistics  
CDCR aims to benefit downstream multi-document applications, but despite recent progress on corpora and system development, downstream improvements from applying CDCR have not been shown yet.  ...  We conclude with recommendations on how to achieve generally applicable CDCR systems in the future — the most important being that evaluation on multiple CDCR corpora is strongly necessary.  ...  Special thanks are due to Jan-Christoph Klie and Nafise Sadat Moosavi for the frequent exchange of ideas. This work was supported by the German Research Foundation through the  ...

Ensemble Named Entity Recognition (NER): Evaluating NER Tools in the Identification of Place Names in Historical Corpora

Miguel Won, Patricia Murrieta-Flores, Bruno Martins
2018 Frontiers in Digital Humanities  
The identification and extraction of toponyms and spatial information mentioned in historical text collections has allowed its use in innovative ways, making possible the application of spatial analysis  ...  In addition, the results showed that these NER systems are not strongly dependent on preprocessing and translation to Modern English.  ...  Most of the NER tools that were considered for our study are based on supervised machine learning, but we nonetheless did not experiment with using the epistolary corpora for training new models, instead  ...
