KnowledgeAnswersIntentQueryArgumentProvenance

If populated, the current query contains an anaphor that refers to the value. For example: U: Weather in Paris. [Weather(location=paris)] G: 65 degrees and sunny. U: How many people live there? [Population(city=paris)] The "there" in the current query would have the "anaphor" field set. NOTE: after a string rewrite this field will not be populated anymore if the rewrite replaced the anaphor with the corresponding value. For example, if we rewrite [How many people there] to [How many people in Paris], the CurrentQuerySignals for "paris" will not contain an "anaphor" message anymore in the following turns. It will only contain an eval_data for the span that corresponds to "paris" in the query.

NOTE: PreviousQuery is used for values that originate directly from QRef entities annotated in the user query. AttentionalEntity is used for values that come from the system (entities published by a dialog). These values could also originate from an entity annotated by QRef in the query, but this is not necessarily the case. SearchAnswerValue is used for values that come from the system as part of the answer of the user query. For example: U: Wife of Barack Obama G: Barack Obama's wife is Michelle Obama Here "Barack Obama" can have an ArgumentProvenance of PreviousQuery, or AttentionalEntity if a dialog publishes that entity and the interpretation pulls the value from it. "Michelle Obama" can have an ArgumentProvenance of SearchAnswerValue, or AttentionalEntity if the dialog publishes that entity and the interpretation pulls the value it.
