The hoodie wiki says it's a sweatshirt with a hood attached, so it'd be logical to make the implication hoodie -> sweatshirt. However, as someone pointed, many people could tag hoodie instead of hood accidentally and then they'll forget to clear the sweatshirt tag later. My suggestion is, creating the alias hoodie -> hooded_sweatshirt and then creating the implication later.
The other option someone else gave is changing the hoodie wiki so it'll include hooded sweaters as well.
