An Analysis of Attention in German Verbal Idiom Disambiguation

1 code implementation LREC (MWE) 2022 Rafael Ehren, Laura Kallmeyer, Timm Lichte

In this paper we examine a BiLSTM architecture for disambiguating verbal potentially idiomatic expressions (PIEs) as to whether they are used in a literal or an idiomatic reading with respect to explainability of its decisions.

Supervised Disambiguation of German Verbal Idioms with a BiLSTM Architecture

no code implementations WS 2020 Rafael Ehren, Timm Lichte, Laura Kallmeyer, Jakub Waszczuk

Supervised disambiguation of verbal idioms (VID) poses special demands on the quality and quantity of the annotated data used for learning and evaluation.

A Neural Graph-based Approach to Verbal MWE Identification

1 code implementation WS 2019 Jakub Waszczuk, Rafael Ehren, Regina Stodden, Laura Kallmeyer

We propose to tackle the problem of verbal multiword expression (VMWE) identification using a neural graph parsing-based approach.

Literal or idiomatic? Identifying the reading of single occurrences of German multiword expressions using word embeddings

no code implementations EACL 2017 Rafael Ehren

Non-compositional multiword expressions (MWEs) still pose serious issues for a variety of natural language processing tasks and their ubiquity makes it impossible to get around methods which automatically identify these kind of MWEs.
