AlchemyAPI is capable of categorizing your HTML, or web-based content. We employ sophisticated statistical algorithms and natural language processing technology to analyze your information, assigning the most likely topic category (news, sports, business, etc.).
API endpoints are provided for performing topic classification on Internet-accessible URLs and posted HTML files.
Extracted meta-data may be returned in XML, JSON, RDF, and Microformats rel-tag formats. More information on text categorization API response formats is available.
