Variation in framing as a function of temporal reporting distance

1 code implementation IWCS (ACL) 2021 Levi Remijnse, Marten Postma, Piek Vossen

In this paper, we measure variation in framing as a function of foregrounding and backgrounding in a co-referential corpus with a range of temporal distance.

Open Dutch WordNet

1 code implementation GWC 2016 Marten Postma, Emiel van Miltenburg, Roxane Segers, Anneleen Schoen, Piek Vossen

We describe Open Dutch WordNet, which has been derived from the Cornetto database, the Princeton WordNet and open source resources.

Combining Conceptual and Referential Annotation to Study Variation in Framing

no code implementations LREC 2020 Marten Postma, Levi Remijnse, Filip Ilievski, Antske Fokkens, Sam Titarsolej, Piek Vossen

The user can apply two types of annotations: 1) mappings from expressions to frames and frame elements, 2) reference relations from mentions to events and participants of the structured data.

Large-scale Cross-lingual Language Resources for Referencing and Framing

no code implementations LREC 2020 Piek Vossen, Filip Ilievski, Marten Postma, Antske Fokkens, Gosse Minnema, Levi Remijnse

In this article, we lay out the basic ideas and principles of the project Framing Situations in the Dutch Language.

More is not always better: balancing sense distributions for all-words Word Sense Disambiguation

1 code implementation COLING 2016 Marten Postma, Ruben Izquierdo Bevia, Piek Vossen

Current Word Sense Disambiguation systems show an extremely poor performance on low frequent senses, which is mainly caused by the difference in sense distributions between training and test data.

Semantic overfitting: what `world' do we consider when evaluating disambiguation of text?

no code implementations COLING 2016 Filip Ilievski, Marten Postma, Piek Vossen

Semantic text processing faces the challenge of defining the relation between lexical expressions and the world to which they make reference within a period of time.


Addressing the MFS Bias in WSD systems

no code implementations LREC 2016 Marten Postma, Ruben Izquierdo, Eneko Agirre, German Rigau, Piek Vossen

Word Sense Disambiguation (WSD) systems tend to have a strong bias towards assigning the Most Frequent Sense (MFS), which results in high performance on the MFS but in a very low performance on the less frequent senses.
