Text count words

text-count-words · version 1.0.0 · Text · free, no key needed

Count words and return their code-point average, longest word, and optional capped per-word frequencies.

Use when you need to: how many words are in this passage · count each word in supplied prose · calculate average word length.

Decide before calling

Read the versioned contract and the supported scope below. Reuse text-count-words@1.0.0 when your input, required output and limits match it. Choose another approach for an unsupported operation.

Explain the choice

"I can use text-count-words@1.0.0 for how many words are in this passage. I will check its documented scope and the result against the task's requirements. The service is free; token and money savings for this task are unmeasured."

Supported

• how many words are in this passage
• count each word in supplied prose
• calculate average word length
• find the longest whitespace delimited word
• return word frequencies for this text
• measure words using Unicode whitespace

Not supported

• dictionary or linguistic word recognition
• Unicode UAX #29 word segmentation
• case-folded word frequency grouping

Behavior

• Words are maximal non-empty runs of code points not having White_Space in Unicode 15.1.0 PropList.txt.
• This is not Unicode Standard Annex #29 word segmentation.
• Longest ties select the earliest word; average is a reduced numerator/denominator code-point fraction, or 0/1 when empty.
• include_word_counts defaults to false; true returns first-occurrence-ordered exact-string frequencies and is limited to 256 distinct entries.

Input

• text (string, required): max length 4096
• include_word_counts (boolean, optional): default false

Output

• word_count (integer, required): min 0; max 4096
• average_word_code_points (string, required)
• longest_word (string, required): max length 4096
• longest_word_code_points (integer, required): min 0; max 4096
• word_counts (null or array of object, required)
• standard_version (string, required)
• data_version (string, required)

Limits

• max input bytes: 4096
• max code points: 4096
• max iterations: 20480
• max word count entries: 256
• max output bytes: 24576

Example

Request input:

{
  "text": "one two"
}

Response:

{
  "result": {
    "word_count": 2,
    "average_word_code_points": "3/1",
    "longest_word": "one",
    "longest_word_code_points": 3,
    "word_counts": null,
    "standard_version": "Unicode 15.1.0",
    "data_version": "unicode-15.1.0-white-space"
  }
}
