Semantinet’s slogan, “Information into knowledge” aptly describes their work. Semantinet is building a giant information graph of people, places and concepts linked together by whichever relationships are detected from both structured and unstructured data sources on the web. It’s a simple thing to describe, but the implications are profound. This type of information technology is so much more powerful than a collection of articles that can be searched by keyword. What we have here resembles how we imagine information and memories are stored in our own minds, and its available to be used in your own project through the Semantinet Knowledge Graph API.
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.”
