The SIGMORPHON 2016 Shared Task - Morphological Reinflection
TLDR
The 2016 SIGMORPHON Shared Task was devoted to the problem of morphological reinflection. Expand

Joint Lemmatization and Morphological Tagging with Lemming
TLDR
We present LEMMING, a modular loglinear model that jointly models lemmatization and tagging and supports the integration of arbitrary global features. Expand

Gender Bias in Contextualized Word Embeddings
TLDR
We quantify, analyze and mitigate gender bias exhibited in ELMo’s contextualized word vectors. Expand

Labeled Morphological Segmentation with Semi-Markov Models
TLDR
We introduce a new hierarchy of morphotactic tagsets and CHIPMUNK, a discriminative morphological segmentation system that explicitly models morphotactics. Expand

Weighting Finite-State Transductions With Neural Context
TLDR
We propose a hybrid FST-LSTM architecture for string-to-string transduction tasks that combines classical finite-state approaches to transduction and newer neural approaches. Expand

UniMorph 2.0: Universal Morphology
TLDR
The Universal Morphology UniMorph project is a collaborative effort to improve how NLP handles complex morphology across the world's languages. Expand

Morphological Smoothing and Extrapolation of Word Embeddings
TLDR
We present a Gaussian graphical model that allows us to extrapolate continuous representations for words not observed in the training corpus, as well as smoothing the representations provided for the observed words. Expand

Generalizing Procrustes Analysis for Better Bilingual Dictionary Induction
TLDR
We show that projecting the two languages onto a third, latent space, rather than directly onto each other, while equivalent in terms of expressivity, makes it easier to learn approximate alignments. Expand

CoNLL-SIGMORPHON 2017 Shared Task: Universal Morphological Reinflection in 52 Languages
TLDR
The CoNLL-SIGMORPHON 2017 shared task on supervised morphological generation required systems to be trained and tested in each of 52 typologically diverse languages. Expand

Cross-lingual Character-Level Neural Morphological Tagging
TLDR
We train character-level recurrent neural taggers to predict morphological taggings for high-resource and low-resource languages together. Expand
