Extract topics | Babel Street

Topic Extractor extracts the most salient themes of a piece of text, and is useful for summarizing documents. Given an input, both a list of concepts and a list of keyphrases are returned. Concepts are higher level topics implicit in the text, but which may or may not actually appear in the text. Keyphrases are found in the text and representative of the overall content.
