This is an abstract Concept Class (no concept can be made an instance of it in the model).

It represents all unordered near Context extractors. Unordered Near Contexts are extractors that look for facts (and anchors) that are close to each other and in any order in some context. How close they are can be specified using the count metadata.

The following elements common to all Near Unordered Contexts. They only differ in the contexts they look in and the different grammatical units that are looked for.

Example model and tests

In the FACTS example model, included with FACTS, the document fact DF5 - Near unordered sentences in the same document - contains an example near unordered sentences in the same document with a near count of 5 set:

All the children need to fire, and be found within 5 sentences of each other. If this is true, the fact will be returned.
