Annotation and Extraction of Multiword Expressions in Turkish Treebanks

Abstract

Multiword expressions (MWEs) present particular and distinctive semantic properties, hence their automatic extraction receives special attention from the natural language processing (NLP) and corpus linguistics community, and is still an active research area. Unfortunately, the creation of necessary resources for this task is quite rigorous and many languages suffer from the lack of these; as in the case for Turkish.This study presents our MWE annotations on recently introduced Turkish Treebanks, which focuses on annotating various types of linguistic units and expressions, including named entities, numerical expressions, idiomatic phrases, verb phrases with auxiliaries and duplications. The paper aims to provide a benchmark and pave the way towards further MWE extraction research for Turkish. To this end, the paper also introduces our experimental results with seven baseline approaches, a dependency parser and a previously introduced rule-based extractor on these annotated corpora. Our highest performances achieved over these resources are about 60% F-scores.

Building the first comprehensive machine-readable Turkish sign language resource: methods, challenges and solutions

“…The studies for Turkish treebanking started in the early 2000s (Atalay et al 2003;Oflazer et al 2003) and have continued since then (Eryiğit 2007a;Sulubacak and Eryiğit 2013;Pamay et al 2015;Eryiğit et al 2015;Sulubacak et al 2016a,b;Sulubacak and Eryigit 2018). Following earlier studies, the Turkish part of the TiDLaR Corpus was annotated in two main layers: morphology and syntax.…”

Projecting Multiword Expression Resources on a Polish Treebank

“…Continuous MWEs such as compound nouns, adverbs and prepositions and conjunctions are covered in some treebanks as in (Abeillé et al, 2003;Branco et al, 2010). Verbal MWEs (VMWEs) have been addressed for a fewer number of languages (Bejček et al, 2011;Eryigit et al, 2015;Seraji et al, 2014), and often restricted to some subtypes only, e.g., light-verb constructions (Vincze and Csirik, 2010).…”
