Researchers have developed a novel graph-based method to analyze how semantic type information is represented in contextualized word embeddings. This approach uses nouns from ten semantic types and annotates corpus instances to distinguish between matching and coerced semantic types. The study proposes two metrics, Neighbor Type Probability (NTP) and Neighbor Type Entropy (NTE), to evaluate the distribution of types in an embedding's neighborhood, finding that sense-enhanced embeddings better capture this semantic information.
