Hi,

In LFG, in addition to the c-structure there is an f-structure. The f-structure encodes functional information about the constituents. For example, as you noted in English the noun phrases of a sentence are the same in structure but functionally some are subjects and some are direct objects. The f-structure in the LFG formalism encodes this kind of information and proponents of the formalism feel that such descriptions behave better cross-linguistically than simple c-structures in isolation. However, I thought you might find this an interesting line because of the strict separation between c-structure and f-structure information. To see an example of what these structures look like check out this link: http://decentius.aksis.uib.no/logon/xle.xml Select English in the drop box and type a simple sentence like "Mary hit the dog" and you get presented with a CFG tree (the c-structure) and an attribute value matrix (the f-structure) which contains functional information like which argument of the predicate is the subject and which is the object. Obviously, there is no direct way of doing this in Prolog. The technology behind this web interface is the Xerox Linguistic Environment (XLE) which isn't available freely as Prolog is.
