“…More elaborate are approaches based on finitestate-related formalisms. They usually indicate the morphological categories and features of individual MWE components, and offer rule-based combinatorial description of their variability patterns (Karttunen et al, 1992;Breidt et al, 1996;Oflazer et al, 2004;Silberztein, 2005;Krstev et al, 2010;Al-Haj et al, 2014;Lobzhanidze, 2017;Czerepowicka and Savary, 2018). They mostly cover continuous (e.g.…”

Because most multiword expressions (MWEs), especially verbal ones, are semantically non-compositional, their automatic identification in running text is a prerequisite for semantically-oriented downstream applications. However, recent developments, driven notably by the PARSEME shared task on automatic identification of verbal MWEs, show that this task is harder than related tasks, despite recent contributions both in multilingual corpus annotation and in computational models. In this paper, we analyse possible reasons for this state of affairs. They lie in the nature of the MWE phenomenon, as well as in its distributional properties. We also offer a comparative analysis of the state-of-the-art systems, which exhibit particularly strong sensitivity to unseen data. On this basis, we claim that, in order to make strong headway in MWE identification, the community should bend its mind into coupling identification of MWEs with their discovery, via syntactic MWE lexicons. Such lexicons need not necessarily achieve a linguistically complete modelling of MWEs' behavior, but they should provide minimal morphosyntactic information to cover some potential uses, so as to complement existing MWE-annotated corpora. We define requirements for such a minimal NLP-oriented lexicon, and we propose a roadmap for the MWE community driven by these requirements.

“…Lexicons similar to SEJF, following the Multiflex paradigm, exist or are under construction for Serbian (Krstev et al, 2010), Greek (Foufi, 2013), and Macedonian (Rafajlovska and Zdravkova, 2015). Various e-lexicographic frameworks were developed for the creation of MWE e-lexicons notably in Turkish (Oflazer et al, 2004), Basque (Alegria et al, 2004), Dutch (Grégoire, 2010), Serbian (Stanković et al, 2011) and Hebrew (Al-Haj et al, 2014), the third one also covers verbal MWEs.…”

We present SEJF, a lexical resource of Polish nominal, adjectival and adverbial multi-word expressions. It consists of an intensional module with about 4,700 multi-word lemmas assigned to 160 inflection graphs, and an extensional module with 88,000 automatically generated inflected forms annotated with grammatical tags. We show the results of its coverage evaluation against an annotated corpus. The resource is freely available under the Creative Commons BY-SA license.

“…In general, such morphological and morphosyntactic properties of phraseological expressions have been studied much more extensively than their valency properties; see e.g. Savary 2008, Al-Haj et al 2013 and references therein. Clearly, further work is needed on finding a natural way to combine valency and paradigmatic constraints on particular phraseological expressions.…”

Phraseology in two Slavic valency dictionaries: limitations and perspectives

et al. 2016

View full text Add to dashboard Cite

Phraseological components of valency dictionaries for two West Slavic languages are presented, namely, of the PDT-Vallex dictionary for Czech and of the Walenty dictionary for Polish. Both dictionaries are corpus-based, albeit in different ways. Both are machinereadable and employable by syntactic parsers and generators. The paper compares the expressive power of the phraseological subformalisms of these dictionaries, discusses their limitations and makes recommendations for their possible extensions, which can be possibly applied also to other valency dictionaries with rich phraseological components.
