The Term Extraction API allows users to perform content analysis by providing a list of significant words or phrases extracted from a larger content. It is one of the technologies used in Yahoo! Search. It uses a RESTful API 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.”
Late last week we reported on Yahoo's decision to shut down two of its APIs: the Term Extraction and the Contextual Web Search (our profiles of the Yahoo Term Extraction API and the Yahoo Search API). But in response to outcry from the developer community since that announcement, it looks like Yahoo will be keeping the Term Extraction alive.
It hasn't been long since developers responded with fear that Yahoo's innovative search tools could go away. Now two of the smaller, but still well-loved, APIs have been given less than a month to live.
