Frequency distribution
Character or word frequency counts. Runs entirely on your device, nothing is uploaded.
Runs on your device. The file is never uploaded.
Frequency distribution counts a text file by word or by character, set with mode, which defaults to word, and prints the top 30 entries with counts and percentage shares. caseSensitive defaults to false. Nothing is filtered or stemmed, so the and of take most rows, and run and running are counted apart.
Questions
Does it count words or characters?
Either, through the mode option, which defaults to word. In word mode a word starts with a letter and then takes in letters, digits, apostrophes and hyphens, so a bare number is not counted as a word. In char mode every character is counted except whitespace, so punctuation and symbols appear in the table alongside letters.
Is the count case-sensitive?
Not by default. caseSensitive defaults to false, so The and the are folded together and reported under the lower-case form. Turn it on and they are counted separately, which is what you want for looking at capitalisation patterns and not what you want for a vocabulary count.
Why does the list stop at 30 entries?
Because that is the cap. Entries are sorted by count, highest first, and the top 30 are printed. The header line above them gives the true totals, the number of distinct items and the number counted overall, so you can tell how much was left out. The percentage on each row is that item's share of the total counted.
Are stop words removed?
No. The, of, and and the rest are counted like any other word and will usually take most of the top 30 rows in English prose. There is no stop list and no stemming, so run and running are separate entries. What you get is a raw count, which is the honest starting point for anything you want to do next.
How is this different from Unicode inspector?
Different question, similar table. This tool counts words or visible characters and reports percentages, for looking at vocabulary and letter distribution. Unicode inspector counts every code point including whitespace and invisible characters, and shows each one with its U+ number and Unicode category, for finding out what is in a file. Use this for content, that one for encoding.
