A Tale of Three Parsers: Towards Diagnostic Evaluation for Meaning Representation Parsing

no code implementations LREC 2020 Maja Buljan, Joakim Nivre, Stephan Oepen, Lilja {\O}vrelid

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.

Multilingual Probing of Deep Pre-Trained Contextual Encoders

no code implementations WS 2019 Vinit Ravishankar, Memduh G{\"o}k{\i}rmak, Lilja {\O}vrelid, Erik Velldal

Encoders that generate representations based on context have, in recent years, benefited from adaptations that allow for pre-training on large text corpora.


Expletives in Universal Dependency Treebanks

1 code implementation WS 2018 Gosse Bouma, Jan Hajic, Dag Haug, Joakim Nivre, Per Erik Solberg, Lilja {\O}vrelid

Although treebanks annotated according to the guidelines of Universal Dependencies (UD) now exist for many languages, the goal of annotating the same phenomena in a cross-linguistically consistent fashion is not always met.

SIRIUS-LTG: An Entity Linking Approach to Fact Extraction and Verification

no code implementations WS 2018 Farhad Nooralahzadeh, Lilja {\O}vrelid

The experiments show that the pipeline with simple Cosine Similarity using TFIDF in sentence selection along with DA model as labelling model achieves the best results on the development set (F1 evidence: 32. 17, label accuracy: 59. 61 and FEVER score: 0. 3778).

In this article, we describe the development of annotation guidelines for family history information in Norwegian clinical text.

Tracing armed conflicts with diachronic word embedding models

no code implementations WS 2017 Andrey Kutuzov, Erik Velldal, Lilja {\O}vrelid

Recent studies have shown that word embedding models can be used to trace time-related (diachronic) semantic shifts in particular words.
