TextRazor is an API that extracts meaning, entities, keyphrases, and topics from text content using natural language processing.

TextRazor provides a Natural Language Processing (NLP) API designed to extract and understand information from text. It identifies entities, disambiguates them, and links them to a comprehensive knowledge base. The API also performs keyphrase extraction, automatic topic tagging, and classification across 19 languages, supporting IAB Content and IPTC Media Topic Taxonomies. The platform offers deep analysis capabilities, including the extraction of relations, typed dependencies between words, and synonyms, which enables the development of context-aware semantic applications. TextRazor can be deployed as a cloud-based service or as a self-hosted text analysis infrastructure, combining state-of-the-art NLP techniques with a vast knowledge base to process documents, tweets, or web pages.
