IDOL OnDemand by HP offers an array of data processing APIs for format conversion, image analysis, indexing, search, and textual analysis. Preview capabilities exist to view how many of these RESTful APIs behave in action. The Entity Extraction API scans an inputted text file and extracts words that match the entity type criteria. These could be people, names, places, company names, phone numbers, URL, credit card numbers, and more. The API returns as list of the content matching the entity types, and also specifies where they were found within the document.
