Method Detail

compareDocuments

public static void compareDocuments(Document response,
                    Document key)

compare the entity annotations (coreference) in Documents 'response' and 'key', updating Document 'response'. The two Documents should be different annotations of the same text.

Two mentions are considered the same if their spans (or the spans of their heads, if they have headC attributes) are the same. Two entities are considered the same if they have the same set of mentions ("mentions" attribute).

There are three cases:

• an entity in response has a corresponding entity in key; update the entity in response with 'status=OK'.
• an entity in response has no corresponding entity in key; update the entity in response with 'status=response'.
• an entity in key has no corresponding entity in response; add a corresponding entity to Document 'response' (adding mentions if necessary) and mark the entity 'status=key'.

In addition, if there are any differences between the entities in the two documents, the annotation 'entitiesDiffer' is added to Document 'response'.

compareCollections

public static void compareCollections(DocumentCollection response,
                      DocumentCollection key)

compare the entity annotations (coreference) in all documents in Document Collections 'response' and 'key', updating the documents in DocumentCollection 'response'. The two collections should be the same size and have Documents which are different annotations of the same text.
