Paradigm Clustering with Weighted Edit Distance
Andrew Gerlach, Adam Wiemerslage, Katharina Kann · 2021
This paper describes our system for the SIGMORPHON 2021 Shared Task on Unsupervised Morphological Paradigm Clustering, which asks participants to group inflected forms together according their underlying lemma without the aid of annotated training data.We employ agglomerative clustering to group word forms together using a metric that combines an orthographic distance and a semantic distance from word embeddings.We experiment with two variations of an edit distance-based model for quantifying orthographic distance, but, due to time constraints, our systems do not outperform the baseline.However, we also show that, with more time, our results improve strongly.
