It only takes two steps to learn how to embed words accurately
Amazon keyword embedding mechanism
1. Amazon’s so-called “keywords” essentially follow the TF-IDF algorithm
The keyword score is directly proportional to the keyword span and inversely proportional to the keyword frequency.
Small science:

  • TF (Term Frequency) indicates the frequency of a term in a text.

  • IDF (Inverse Document Frequency) indicates the prevalence of keywords

2. Therefore, when embedding words, you should pay attention to dispersion and avoid being too concentrated.
When optimizing your copywriting, pay attention to the following three points:
  • Word choice (word relevance)
  • Frequency of a word (how many times a word is repeated)
  • Reading experience (language localization)
