Yahoo Content Analysis replaces Yahoo!â€™s Term Extraction service and lets users perform content analysis on text or a URL. The API is able to extract key terms from the content and rank them based on their overall importance to the content.
The YahooContent Analysis API detects entities/concepts, categories, and relationships within unstructured content. It ranks those detected entities/concepts by their overall relevance, resolves those if possible into Wikipedia pages, and annotates tags with relevant meta-data. The API uses RESTful calls and responses are formatted in XML.
The new Yahoo Content Analysis API capitalizes on the success of its term extraction API while adding new functionality. The reborn implementation not only extracts terms and entities but ranks them based on perceived importance within the article. Peter Levinson, product manager for Yahoo Content Analysis, says “The new API gives developers actionable metadata about their content. By extracting and then ranking terms on the page, the API separates signal from noise in unstructured content.”
