How to Use This Calculator
  1. Enter or paste the text corpus to analyze.
  2. Set the minimum frequency threshold to filter out rare hapax legomena.
  3. Review the top-N word list ranked by frequency and the type-token ratio.
  4. Use the frequency list to identify domain-specific vocabulary for glossary development.
  5. Compare word frequency distributions across texts to measure register consistency.

What each input means

Corpus Size (total words)
Total number of words (tokens) in your text corpus.
Unique Words (types)
Number of distinct word forms (types) in the corpus.
Target Word Frequency
Number of times your target word appears in the corpus.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Corpus Size (total words) = 50000, Unique Words (types) = 5000, Target Word Frequency = 100 = 3 input(s) provided
  2. Calculate Type-Token Ratio
    Type-Token Ratio
    0.1 = 0.1
  3. Calculate Estimated Hapax Legomena
    Estimated Hapax Legomena
    2500 = 2500
  4. Calculate Frequency Rank
    Frequency Rank = max(1
    55 = 55
