I have came across the Winograd SHRDLU program and I found it very interesting and aspiring.

What is the consensus regarding it? Are there any similar attempts?

I'm reading the book of Terry Winograd Understanding Natural Language where he discusses the functionality of the program, LISP language and more. I also found the linguist Michael Halliday and the linguistic theory Systemic (functional) Grammar which is mentioned in Winograd's book.

Are there any other ai/NLP that use this theory as a basis for the semantic functionality?

Since SHRLDLU was developed, there have been several more attempts to develop natural language understanding systems. For example, there is one document that describes an implementation of a self-extending natural language user interface.

SHRDLU was programmed in beginning of 1970s. In the late 1980s and early 1990s two important projects were realized in the area of language grounding: TWIG (by I. D. Horswill) and JACK (by N. I. Badler). Both attempts can be seen as a modern implementation of SHRDLU. In a virtual 3D environment the player can activate commands with the help of a natural language speech-interface. That means, possible actions are grouped in a Maniac Mansion style GUI. Both projects (JACK and TWIG) are well documented in Google Scholar and are a standard example in the domain of language-to-animation processing. Like the SHRDLU project, the sourcecode is missing, so it is not possible to download a running prototype.
