Aggregated learning data from Kimchi Reader users

Real-time

Words Analyzed

Total words processed by the lemmatizer — the engine that converts conjugated Korean words (like 먹었어요) back to their dictionary form (먹다).

This count excludes the daily indexing of the recommendation system.

Where People Study

Community-wide breakdown of dictionary activity by content. Only includes content with 10+ hours of total study time.
Every 3h

This indicates how often the data is refreshed (Every 3h), not the time range of the data itself.

Word Knowledge by Frequency

For each word, I measured what % of users know it — then grouped by frequency rank.

  • The line shows learning tracks frequency well (common words get learned first)
  • The bands show how much popularity varies within each tier
What to notice:
  • High line = most users know these words; low = few do
  • Wide bands = learners diverge on what they know
  • Narrow bands = everyone learns similar words
Known: Only words marked as "known"
Seen: Words marked as "known" or "seen"
