-
Lower angular distance values in the embedding space mean the items are closer in meaning.

Morphology
The compound combines 'angular' (relating to angles) and 'distance' (a measure of separation), so its basic meaning — a distance measured in terms of an angle or angular difference — is directly derivable from the constituents. Although the term is used in technical domains (math/data science) with specific formulas, the compositional logic is regular and cross-linguistically recognizable, so a B1 learner who knows both words would grasp the general idea.
Etymology
Angular distance uses the same picture but for directions or arrows from the same point: if the arrows point the same way the angle is small, if they point apart the angle is large. So in math and data work angular distance is a number that shows the 'difference' or 'similarity' between items.
