Eh, it is hit or miss. Same with definitions of words. I'm a native speaker of American English, so I know the most common definitions of words. When I'm touching a word for a definition, it's usually because it's being used in an unusual way. Consider this passage from Around the World in 80 Days...
"He passed ten hours out of the twenty-four in Saville Row, either in sleeping or making his toilet."
Huh? Does the character need to eat more fiber? Try selecting "toilet" in that sentence for a definition. You'll get the most common one, which only makes me more confused. AI should have an easy time knowing that the appropriate meaning is the OED's definition 5a:
"Frequently in form toilette. The action or process of washing, dressing, or arranging the hair. Frequently in to make one's toilet."
"He passed ten hours out of the twenty-four in Saville Row, either in sleeping or making his toilet."
