Topological Data Analysis for Word Sense Disambiguation
This addresses word sense induction for natural language processing, but appears incremental as it applies an existing topological method to a known problem.
The authors tackled word sense disambiguation by developing an unsupervised algorithm using topological data analysis, specifically persistent homology barcode, and demonstrated low relative error on the SemCor dataset.
We develop and test a novel unsupervised algorithm for word sense induction and disambiguation which uses topological data analysis. Typical approaches to the problem involve clustering, based on simple low level features of distance in word embeddings. Our approach relies on advanced mathematical concepts in the field of topology which provides a richer conceptualization of clusters for the word sense induction tasks. We use a persistent homology barcode algorithm on the SemCor dataset and demonstrate that our approach gives low relative error on word sense induction. This shows the promise of topological algorithms for natural language processing and we advocate for future work in this promising area.
