1. Academic database: An academic database like HowNet is a good place to find authoritative definitions. Enter keywords in the search box, such as "employment", and then browse relevant academic articles to see if there is any definition you need.
2. Professional dictionaries: Professional dictionaries usually provide authoritative explanations of terms and definitions in specific fields. You can look up some professional dictionaries related to your topic, such as law, medicine and psychology.
3. Academic journals: Academic journals usually publish authoritative interpretations and analysis of specific topics by some scholars. You can get the definition you need by consulting journal articles in related fields.
4. Official documents: Some official institutions or authoritative organizations may issue some official definitions for specific topics. For example, government agencies, international organizations and trade associations may provide official explanations for some key terms.
5. Reference books: Some books, especially textbooks or authoritative reference books in specific fields, may provide authoritative explanations of some terms. You can try searching for reference books in related fields in the library or online bookstore.
The problem with the search HowNet may be that it doesn't provide direct search service. You can try to use related video tutorials on www.hi. com, or directly search related academic resources on www.hi. com.
I hope these suggestions will help you!
