Incrementally build up recognizers over an abstract token that combine to create multiple possible interpretations.

Key features:

• Abstract over token type to support "rich" tokens like we have at Storyscript.
• May generate multiple interpretations of the same token span.
• Produces a set of ranges over the input token list with different attributes, for example:

Layering

The key idea here is to enable starting from a bunch of vague tags and slowly building meaning up through incrementally adding information that builds on itself.

Simplification: Money = '$' + Number

$ 123 . 00 ╰Natural ╰Punct ╰Natural ╰Amt(Decimal)╯ ╰Money($/£, Num)─╯

Simplification:

• Location(NYC) = 'New' + 'York' + 'City'
• Location(AMS) = 'Amsterdam'
• Address(Person, Location) = Person + Verb('live') + Predicate('in') + Location

I live in New York City ╰Noun ╰Noun ╰Adj ╰Predicate ╰Verb ╰Noun ╰Person(Self) ╰──Location─╯ ╰────Address(Person, Location)─────╯
