Link Structure Changed

Well, the link structure in preverbal messages is actually functional now. Instead of simply being a string representation of the link structure, preverbal messages have a tree structure that represents the link structure. These tree structures have three types of nodes: "and", "or", "lemma", and "link". They each have different satisfaction requirements. "and" nodes are satisfied iff all of their children are satisfies. "or" nodes are satisfied iff exactly one of their children is satisfied. "lemma" nodes are satisfied iff their only child is satisfied (these generally are the root of a PVM). "link" nodes are only satisfied if they have been joined to a link node in another PVM. The whole importance of satisfaction is mentioned in a short paper I'm still in the process of revising. Once its done I'll post a link to it here.

There is a copy of the NLGen2 technical report at http://www.ucs.louisiana.edu/~bal2277/NLGen2.odt . This file will be updated periodically, as it is a work in progress.

Preverbal Message Generation

The preverbal message generation portion of NLGen2 is working. It creates the Preverbal Message data structure, which is a set of strings representing the propositions associated with that particular preverbal message and its link structure. The link structure is currently represented as a string, but this will not be the final representation. It will be changed soon to be a restricted type of tree structure which is currently under development, but the specific nature of that tree structure will not be set in stone until more details of the merge algorithm have been worked out.
