AIDA is a framework and online tool for entity detection and disambiguation. Given a natural-language text or a Web table, it maps mentions of ambiguous names onto canonical entities (e.g., individual people or places) registered in the YAGO2 knowledge base.
A reconciliation service is a web service that, given some text which is a name or label for something, and optionally some additional details, returns a ranked list of potential entities matching the criteria. The candidate text does not have to match each entity's official name perfectly, and that's the whole point of reconciliation--to get from ambiguous text name to precisely identified entities. For instance, given the text "apple", a reconciliation service probably should return the Apple Inc. company, the apple fruit, and New York city (also known as the Big Apple).
