  • A New Massive Multilingual Dataset for High-Performance Language Technologies 
    de Gibert, Ona; Nail, Graeme; Arefev, Nikolay; Bañón, Marta; van der Linde, Jelmer; Ji, Shaoxiong; Zaragoza-Bernabeu, Jaume; Aulamo, Mikko; Ramírez-Sánchez, Gema; Kutuzov, Andrei; Pyysalo, Sampo; Oepen, Stephan; Tiedemann, Jörg (Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2024)
    We present the HPLT (High Performance Language Technologies) language resources, a new massive multilingual dataset including both monolingual and bilingual corpora extracted from CommonCrawl and previously unused web ...
  • A tale of four parsers: methodological reflections on diagnostic evaluation and in-depth error analysis for meaning representation parsing 
    Buljan, Maja; Nivre, Joakim; Oepen, Stephan; Øvrelid, Lilja (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract We discuss methodological choices in diagnostic evaluation and error analysis in meaning representation parsing (MRP), i.e. mapping from natural language utterances to graph-based encodings of semantic structure. ...
  • A tale of three parsers: Towards diagnostic evaluation for meaning representation parsing. 
    Buljan, Maja; Nivre, Joakim; Oepen, Stephan; Øvrelid, Lilja (Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2020)
    We discuss methodological choices in contrastive and diagnostic evaluation in meaning representation parsing, i.e. mapping from natural language utterances to graph-based encodings of its semantic structure. Drawing ...
  • HPC-ready Language Analysis for Human Beings 
    Lapponi, Emanuele; Velldal, Erik; Vasov, Nikolay; Oepen, Stephan (Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2013)
    This demonstration presents a first operable pilot of the Language Analysis Portal (LAP), an ongoing project within the Norwegian CLARINO initiative that aims at providing easy access to Language Technology (LT) tools ...
  • On Different Approaches to Syntactic Analysis Into Bi-Lexical Dependencies. An Empirical Comparison of Direct, PCFG-Based, and HPSG-Based Parsers 
    Ivanova, Angelina; Oepen, Stephan; Dridan, Rebecca; Flickinger, Dan; Øvrelid, Lilja (Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2013)
    We compare three different approaches to parsing into syntactic, bi-lexical dependencies for English: a ‘direct’ data-driven dependency parser, a statistical phrase structure parser, and a hybrid, ‘deep’ grammar-driven ...
  • Semantic Technologies for Querying Linguistic Annotations: An Experiment Focusing on Graph-Structured Data 
    Kouylekov, Milen; Oepen, Stephan (Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2014)
    With growing interest in the creation and search of linguistic annotations that form general graphs (in contrast to formally simpler, rooted trees), there also is an increased need for infrastructures that support the ...
  • The Talk of Norway: A Richly Annotated Corpus of the Norwegian Parliament, 1998–2016 
    Lapponi, Emanuele; Søyland, Martin G.; Velldal, Erik; Oepen, Stephan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    In this work we present the Talk of Norway (ToN) data set, a collection of Norwegian Parliament speeches from 1998 to 2016. Every speech is richly annotated with metadata harvested from different sources, and augmented ...
  • Towards large-scale language analysis in the cloud 
    Lapponi, Emanuele; Velldal, Erik; Vazov, Nikolay Aleksandrov; Oepen, Stephan (Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2013)
    This paper documents ongoing work within the Norwegian CLARINO project on building a Language Analysis Portal (LAP). The portal will provide an intuitive and easily accessible web interface to a centralized repository of ...
  • Transfer and Multi-Task Learning for Noun–Noun Compound Interpretation 
    Fares, Murhaf; Oepen, Stephan; Velldal, Erik (Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2018)
    In this paper, we empirically evaluate the utility of transfer and multi-task learning on a challenging semantic classification task: semantic interpretation of noun--noun compounds. Through a comprehensive series of ...
