Morpho-syntactic Lexicon Generation Using Graph-based Semi-supervised Learning

2015-12-16 · TACL 2016 1 · Manaal Faruqui, Ryan Mcdonald, Radu Soricut

Morpho-syntactic lexicons provide information about the morphological and syntactic roles of words in a language. Such lexicons are not available for all languages and even when available, their coverage can be limited. We present a graph-based semi-supervised learning method that uses the morphological, syntactic and semantic relations between words to automatically construct wide coverage lexicons from small seed sets. Our method is language-independent, and we show that we can expand a 1000 word seed lexicon to more than 100 times its size with high quality for 11 languages. In addition, the automatically created lexicons provide features that improve performance in two downstream tasks: morphological tagging and dependency parsing.

Towards a Semi-Automatic Detection of Reflexive and Reciprocal Constructions and Their Representation in a Valency Lexicon

2020-05-01 · LREC 2020 5 · V{\'a}clava Kettnerov{\'a}, Marketa Lopatkova, Anna Vernerov{\'a}, Petra Barancikova

Valency lexicons usually describe valency behavior of verbs in non-reflexive and non-reciprocal constructions. However, reflexive and reciprocal constructions are common morphosyntactic forms of verbs. Both of these cons…

First Steps towards the Semi-automatic Development of a Wordformation-based Lexicon of Latin

2012-05-01 · LREC 2012 5 · Marco Passarotti, Francesco Mambrini

Although lexicography of Latin has a long tradition dating back to ancient grammarians, and almost all Latin grammars devote to wordformation at least one part of the section(s) concerning morphology, none of the today a…

OFrLex: A Computational Morphological and Syntactic Lexicon for Old French

2020-05-01 · LREC 2020 5 · Ga{\"e}l Guibon, Beno{\^\i}t Sagot

In this paper we describe our work on the development and enrichment of OFrLex, a freely available, large-coverage morphological and syntactic Old French lexicon. We rely on several heterogeneous language resources to ex…

To Pay or to Get Paid: Enriching a Valency Lexicon with Diatheses

2014-05-01 · LREC 2014 5 · Anna Vernerov{\'a}, V{\'a}clava Kettnerov{\'a}, Mark{\'e}ta Lopatkov{\'a}

Valency lexicons typically describe only unmarked usages of verbs (the active form); however, verbs prototypically enter different surface structures. In this paper, we focus on the so-called diatheses, i.e., the relatio…

A Graph Auto-encoder Model of Derivational Morphology

2020-07-01 · ACL 2020 6 · Valentin Hofmann, Hinrich Sch{\"u}tze, Janet Pierrehumbert

There has been little work on modeling the morphological well-formedness (MWF) of derivatives, a problem judged to be complex and difficult in linguistics. We present a graph auto-encoder that learns embeddings capturing…
