Not seen elsewhere

ePADD Disambiguation • External resolution

– ePADD resolves entities to the FAST for person names, and Freebase for location and organizations.

• Internal resolution – ePADD generates a list of internal

“authority” records consisting of all recognized entities and multi-word address book names

– When the user hovers over such names or acronyms in an email, possible resolutions to internal authority records are shown in decreasing order of confidence.
