(2021). The fine implicative structure of European Portuguese conjugation. Isogloss. Open Journal of Romance Linguistics. PDF Publication Dataset
Recent literature has highlighted the extent to which inflectional paradigms are organised into systems of implications allowing speakers to make full use of the inflection system on the basis of exposure to only a few forms of each word. The present paper contributes to this line of research by investigating in detail the implicative structure of European Portuguese verbal paradigms. After …
(2021). Leaving the stem by itself. All Things Morphology: Its independence and its interfaces. PDF Publication
Stem allomorphy plays a central role in the recent history of morphology, in no small part thanks to a research program initiated by Aronoff (1994). Yet, there is no agreed upon way of deciding whether some bit of form should be considered a proper part of a stem allomorph or an independent exponent. We explore the possibility of just doing away with the notion of stem allomorphy in inflection. We …
(2021). One lexeme, many classes: inflection class systems as lattices. One-to-Many Relations in Morphology, Syntax and Semantics. PDF Publication
This paper discusses the nature of inflection classes (ICs) and provides a fully im- plemented methodology to conduct typological investigations into their structure. ICs (conjugations or declensions) are sets of lexemes which inflect similarly. They are often described as partitioning the set of lexemes, but similarities across classes lead some authors to favor hierarchical descriptions. While …

Most models of inflectional morphology rely at their core on the identification of recurrent and diverging material across inflected forms. Across theoretical frameworks, this can be expressed in terms of morpheme segmentation, rules, processes, patterns or analogies. Finding these recurrences in large structured lexicons is an important step in empirical computational morphology, where analyses …
(2020). Opening the Romance Verbal Inflection Dataset 2.0: A CLDF lexicon. Proceedings of The 12th Language Resources and Evaluation Conference. PDF Publication
We introduce the Romance Verbal Inflection Dataset 2.0, a multilingual lexicon of Romance inflection covering 73 varieties. The lexicon provide verbal paradigm forms in broad IPA phonemic notation. Both lexemes and paradigm cells are organized to reflect cognacy. Such multi-lingual inflected lexicons annotated for two dimensions of cognacy are necessary to study the evolution of inflectional …
(2020). Automated Parsing of Interlinear Glossed Text from Page Images of Grammatical Descriptions. Proceedings of The 12th Language Resources and Evaluation Conference. PDF
Linguists seek insight from all human languages, however accessing information from most of the full store of extant global linguistic descriptions is not easy. One of the most common kinds of information that linguists have documented is vernacular sentences, as recorded in descriptive grammars. Typically these sentences are formatted as interlinear glossed text (IGT). Most descriptive grammars, …
(2018). Classifications flexionnelles: Étude quantitative des structures de paradigmes. Université Sorbonne Paris Cité - Université Paris Diderot (Paris 7), PhD thesis under the supervision of Olivier Bonami. PDF
This dissertation adopts the Word and Paradigm approach and elaborates computationaltools to investigate precisely the similarity structure of inflection class systems based on in-flectional lexicon. We study Arabic, Yaitepec Chatino, Zenzontepec Chatino, English, French,Navajo and European Portuguese verbs as well as Russian nouns.
(2017). When segmentation helps. Implicative structure and morph boundaries in the Navajo verb. First International Symposium on Morphology (ISMo). PDF Slides
Recent work in Word and Paradigm morphology argues that the implicative structure of paradigms is expressed in terms of relations between surface words, and that studying the structure of paradigms in terms of sub-word units is misleading if not outright impossible (Ackerman et al, 2009; Blevins, 2006, 2016; Bonami & Beniamine, 2016). The argument typically rests on the observation that a word …
(2017). Inferring Inflection Classes with Description Length. Journal of Language Modelling. PDF DOI
We discuss the notion of an inflection class system, a traditional ingredient of the description of inflection systems of nontrivial complexity. We distinguish systems of microclasses, which partition a set of lexemes in classes with identical behavior, and systems of macroclasses,which group lexemes that are similar enough in a few larger classes. On the basis of the intuition that macroclasses …
(2017). Un algorithme universel pour l'abstraction automatique d'alternances morphophonologiques. 24e Conférence sur le Traitement Automatique des Langues Naturelles (TALN). PDF
We present an implemented algorithm for the inference of morphophonological alternation patterns between word-forms. It is universal in that it leads to comparable classifications across languages without expectations on the shape of the alternations it searches for. Alternation patterns are anecessary first step for the quantitative study of morphology in the Word and Paradigm framework.
(2016). Joint predictiveness in inflectional paradigms. Word Structure. PDF DOI
This paper contributes to addressing the Paradigm Cell Filling Problem (PCFP) in inflectional paradigms, as defined by Ackerman et al. (2009). We define a method for extending the use of conditional entropy to address the PCFP to prediction based on multiple paradigm cells. We apply this method to French and European Portugese and show that, on average, knowledge of multiple paradigm cells is …
