Applicative universal grammar (AUG) is a far-reaching approach in linguisics. Seeing its main goals (and comparing it to other approaches), it could be characterised as
- because it does not follow a “grammar vs semantics” view, and has a relational approach to understand sign and meaning
- wanting not only to enable us to write better natural language processing projects, but also to understand better how language works. Also ultimate questions (like explaining why the languages of the word show both deep resemblences and difffereces, or why children can lern such a difficult thing like language) are tried to solve
- because it makes a difference -- it separates two levels in understanding how language works: a common genotype grammar is underlying in each language, enabling us to discover invariants and general resemblences, leaving the explanations of specific differences to the level called phenotype grammar
These levels in understanding language are the followings:
- a genotype grammar is common in all human languages -- AUG aims to find invariants, explain concepts abstracting away from conrete languages.
- phenotype grammars are responsible special features of languages
Attribute universal grammar uses many thoughts from combinatory logic.

2 General resources
The same author has also an entire homepage for the topic.
As an article describing what AUG is, see also Shaumyan's Two Paradigms of Linguistics: The Semiotic versus Non-Semiotic Paradigm.
Sebastian Shaumyan's long answers to comments in Disc: Ungrammatical Sentences gives examples, thus can help at understanding the above mentioned materials -- by discussing the notions like meaning, grammatical vs syntactic etc.
Some other citings and fragments from Sebastian Shaumyan can be read here.

4 Implementing these ideas
A Haskell application for natural language parsing, based on Applicative Universal Grammar (AUG) is described in Mark P. Jones', Paul Hudak's and Sebastian Shaumyan's Using Types to Parse Natural Language (if this link is busy, here is another location). The Haskell source code given by the article is full, it can be run by Gofer, and after a few modification, by GHC too (transpose must be explictly imported from standard library module Data.List, and class Text renamed to Show).
A more detailed description of the topic of this previous article described in Sebastian Shaumyan and Paul Hudak's Linguistic, Philosophical, and Pragmatic Aspects of Type-Directed Natural Language Parsing
