A Novel Neural Sequence Model with Multiple Attentions for Word Sense Disambiguation

Word sense disambiguation (WSD) is a well researched problem in computational linguistics. Different research works have approached this problem in different ways. Some state of the art results that have been achieved for this problem are by supervised models in terms of accuracy, but they often fall behind flexible knowledge-based solutions which use engineered features as well as human annotators to disambiguate every target word. This work focuses on bridging this gap using neural sequence models incorporating the well-known attention mechanism. The main gist of our work is to combine multiple attentions on different linguistic features through weights and to provide a unified framework to accomplish this. This weighted attention allows the model to easily disambiguate the sense of an ambiguous word by attending to a suitable portion of a sentence. Our extensive experiments show that weighted multiple attention enables a more versatile encoder-decoder model leading to state of the art results.
