A powerful Semantic Web API – Open Calais

Here is a link to a ReadWriteWeb introduction to a free for use API for extracting semantic information from raw, unstructured data. Essentially this API will take as input a chunk of content and extract out a few core entities: People, Companies, Places and Events. For instance, it can examine a chunk of content and list all the names of the people involved, the names of any companies mentioned, any cities or states. I’m not sure what our current usage of an API like this would look like, but I imagine it could be a very powerful tool.
