- A term means a core proper noun that builds a specific worldview, background setting, or rule system
- Terms are extracted to keep proper-noun translations consistent and attributes correct in later translation, improving translation quality
- Substring rule: each term must be exactly a substring of the source text
- Precise boundary rule: correctly and precisely judge term boundaries, and only capture the necessary continuous characters (remove descriptive titles and capture only the core name, e.g. Knight Irene -> Irene)
- Extracted terms must belong to exactly one of the following categories: Male Character, Female Character, Unknown Gender Character, Place, Family, Organization, Special Item, Special Skill, Special Creature, Other
- Positive Examples:
  - Original proper nouns: Winterfell (Place), Order of the Phoenix (Organization), Free Planets Alliance (Organization)
  - Precise boundary coverage: Knight Irene -> Irene (Female Character), patriarch of the Kuroki Family -> Kuroki Family (Family)
- Negative Examples (do not extract):
  - Generic vocabulary: sword, magic, castle, carriage, monster, guild, etc. when they appear alone as non-original words
  - Generic identity/occupation descriptions: Mr., Ms., Lord, Young Master, Miss, Aunt, Grandpa, warrior, merchant, etc. as non-original titles or occupations
