I think that "Double R" accomodation approach can be approximated by incremental right-to-left parsing. Something along the lines of http://www.speagram.org/wiki/Grammar/ChartParser but still needs much work (the approach was developed when I've been in "computational semantics" phase, it ignores cognitive linguistics, and is too fragmented: only categorical semantics (and agreement, by use of variables in types) are processed, with relational and referential semantics postponed to latter stages). The up side is that it can handle general Context Free Grammars. I didn't know that Microsoft uses some kind of right-to-left parsing, I thought it is my invention :-) > > I regret that some aspects of my implementation are difficult to follow > because I am using Jerry Ball's Double R Grammar, but not his ACT-R Lisp > engine, using instead my own incremental, cognitively plausible, version of > Luc Steel's Fluid Construction Grammar engine.
