and answering reachability queries over Direct Acyclic Graph. In this paper, we propose a
new hierarchical embedding, the Euclidean Embedding (EE), that is correct by design due to
its mathematical formulation and associated lemmas. Such embedding can be constructed
during the visit of a taxonomy, thus making it faster to generate if compared to other learning-
based embeddings. After proposing a novel set of metrics for determining the embedding …
