TLDR
This article demonstrates an opposite approach: ontology-based entailing of words in combination with simple shallow parsing rules, which allows us to increase UAS metrics from 0.82 for SpaCy to 0.834 for the authors' approach.Abstract:
The common approach to the analysis of natural texts implies that semantic analysis should following the stage of parsing. However, medical texts are known as very complicated and written in a very specific language. Traditional parsers are demonstrating relatively small productivity here. In this article, we are demonstrating an opposite approach: ontology-based entailing of words in combination with simple shallow parsing rules. It allows us to increase UAS metrics from 0.82 for SpaCy to 0.834 for our approach.read more
