Rephrase

The Paraphrase and Rephrase endpoints offer paraphrasing for particular styles. Given an input sentence, the endpoint returns output sentences that preserve meaning but use alternative phrasings or styles.

Try it out

Note that while the paraphrases/rephrases retain the same general meaning, they vary in how much they differ from the input sentence. Put another way, while the syntax and terminology of the input may change, the semantics should be preserved.

Paraphrase POST

DEPRECATED Please instead use the Rephrase endpoint with mapping set to paraphrase.

The paraphrase endpoint provides alternative phrasings of an input text while preserving meaning and intent. An example input might be: "How are you?" with the output paraphrases, "How's it going?", "What's up?", and "How are you doing?".

Request Parameters

key: String
32-character API key

text: String
Input query to paraphrase.

diversity: Float [Coming soon]
Ranges from 0 to 1. 0 means to not encourage diversity beyond the usual sampling. 1 means to make the outputs as diverse as possible (while still preserving semantics).

num_results: Integer [Coming soon]
Number of results to return. The minimum is 1. The maximum will depend on other settings, but is generally around 8. Contact us if you need additional results. Additional results will incur additional costs.

Response Parameters

results: JSON, array of paraphrases. Sample structure:

Rephrase POST

In addition to the paraphrase endpoint, the rephrase endpoint also offers a few style transformations:

• Informal to Formal (informal_to_formal): Given a casual/informal input text, generate a more formal/professional output. You can test the endpoint here.
• Passive to Active (passive_to_active): Generate sentence in active voice given sentence in passive voice. You can test the endpoint here.
• Long to Short / Summarize: This is offered by Sapling's summarize endpoint.
• Split (sentence_split): Given a long/convoluted sentence, split it into two sentences. You can test the endpoint here.
• Short to Long / Expand (expand): Given some text, provide a longer version of the text while trying to (mostly) preserve the same meaning. The opposite operation of summarization.
