A simple fact strategy is used when, for a document fact, you are returning a single fact name. There may be more than one such fact being returned, but they are all of the same fact name.

What Do We Need to Know for Our Fact Extraction Strategy?

1. Is the fact locatable using a zone?
   That is, is it a phrase range, defined by either a zoner (such as a date or a person), a text pattern, or a matching label (including stemming, casing, etc.)?
2. Are there several instances of such zones in the content?
   There may be zones that are not considered facts.
3. Are there several instances of the fact potentially to return?
   There may be more than one fact to be returned.

Decision Tree

It’s a simple fact—there is only one fact name returned for the document fact.

Can that simple fact be identified in and of itself?
That is, is it a simple zone such as an entity, a textual pattern, or a concept?

1. YES: Are there more than one simple zone that could appear in the content, where some zones are not a fact?
   1. YES: Might there be multiple facts?
      1. YES: For each fact, is each in its own context instance?
         1. YES: Then we can use any context we want.
         2. NO: Then we cannot use any context we want—we have to use one that supports this scenario.
      2. NO: Then we can use any context we want.
   2. NO: Then we can use any context we want.
2. NO: We cannot use any context we want—we have to use one that supports
