Modeling Derivational Morphology in Ukrainian
نویسندگان
چکیده
We report on a study applying compositional distributional semantic models (CDSMs) to a set of Ukrainian derivational patterns. Ukrainian is an interesting language as it is morphologically rich, and low-resource. Our study aims at resolving inconsistent results from previous studies which employed CDSMs for derivation; we provide evidence for a cross-lingual advantage of CBOW over NMF representations, as well as a simple additive over a lexical function model. In addition, we present two case studies in which we test the capabilities of CDSMs to deal with pattern-level ambiguity and apply the same CDSMs to inflectional patterns.

Rule-based versus associative processes in derivational morphology.
The present article examines whether derivational morphology shows evidence of an associative memory structure. A distributional analysis of stems of attested derivational forms revealed evidence of clustering around phonological properties (gangs) for all nonneutral affixes but only a few neutral affixes. Subjects' acceptability ratings for novel complex words revealed sensitivity to the gang ...
متن کاملDErivBase: Inducing and Evaluating a Derivational Morphology Resource for German
Derivational models are still an underresearched area in computational morphology. Even for German, a rather resourcerich language, there is a lack of largecoverage derivational knowledge. This paper describes a rule-based framework for inducing derivational families (i.e., clusters of lemmas in derivational relationships) and its application to create a highcoverage German resource, DERIVBASE,...
متن کاملThe Form and Content of Derivational Relations
Morpheme based theories of word structure encourage us to think of derived words (e.g. \innatable") as built by adding one complex of phonological, syntactic and semantic content (/{bl j /, Adjective, `able to be verbed') to another (/innejt/, Verb | +NP]], `inflate'). This model lacks generality in a number of ways, however. (a) Derivational relationships may not involve the simple addition of...
متن کاملParadigm Completion for Derivational Morphology
The generation of complex derived word forms has been an overlooked problem in NLP; we fill this gap by applying neural sequence-to-sequence models to the task. We overview the theoretical motivation for a paradigmatic treatment of derivational morphology, and introduce the task of derivational paradigm completion as a parallel to inflectional paradigm completion. State-of-the-art neural models...
متن کاملHindi Derivational Morphological Analyzer
Hindi is an Indian language which is relatively rich in morphology. A few morphological analyzers of this language have been developed. However, they give only inflectional analysis of the language. In this paper, we present our Hindi derivational morphological analyzer. Our algorithm upgrades an existing inflectional analyzer to a derivational analyzer and primarily achieves two goals. First, ...
