How Word Frequency Counting Works

Word frequency counting breaks text into word-like tokens.

Each word is counted and ranked.

Density shows how often a word appears as a percentage of counted words.

Filters can remove stop words, punctuation, numbers, or short terms.

Results help reveal repeated words and text patterns.

Word Frequency, Density, and Repeated Terms Explained

Frequency

The number of times a word appears.

Unique words

Distinct words after selected normalization.

Repeated words

Words appearing more than once.

Density

A word’s share of the counted words.

Stop Words, Case Sensitivity, and Stemming Notes

Stop words are common words like “the”, “and”, and “to”.
Removing stop words can highlight topic-specific terms.
Case-insensitive mode treats “Data” and “data” as the same word.
Case-sensitive mode keeps different capitalizations separate.
Stemming is not implemented, so run, runs, and running stay separate.
English stop words are not suitable for every language.

Common Word Frequency Examples

“apple apple banana” shows apple count 2 and banana count 1.
“Data data DATA” counts as one word when ignore case is enabled.
“The quick brown fox” may hide “the” when stop words are enabled.
“SEO, seo, SEO” depends on case and punctuation settings.
A repeated keyword can have a density percentage.
Filtering short words can remove terms like “a” and “I”.
