Alchemy had types associated with concepts, but Discovery does not. It was useful to filter returned concepts to remove people and locations, particularly if we were displaying those elsewhere. The people returned as concepts, for example, were often associations with entities in the document, and (like many concepts) not explicitly mentioned in the text. Having J Edgar Hoover come back as a concept every time the FBI is mentioned, for example, is often not useful, and it was helpful to be able to filter these kinds of spurious associations out.
Why is it useful?
