Twinword Topic Tagging API

Twinword creates tools to collect data describing the ways in which people associate concepts. The tools include word association tests, the word graph dictionary, e-commerce recommendations, document detection, and more. Twinword provides a series of APIs that expose some of these tools.
The Twinword Topic Tagging API uses contextual language understanding to deliver programmatically generated tags for any given string of text. Developers simply pass a GET request containing up to 200 words or 3000 characters of text, and the API responds with a list of keywords and topics weighted for relevancy.
