GTFL Application Example I

This page will look very ugly unless you use a recent version of Safari, Firefox or Chrome.

This debug trace was generated by the Fluid Construction Grammar framework as a side effect of constructing the utterance "Mary tossed me a drink" from a given meaning.

It shows the initial linguistic structure ("source cfs"), the linguistic rules that were applied, the search tree that was built for finding out which rules to apply in which order, the resulting linguistic structure and finally the utterance.

Clicking on almost any non-black element will reveal a detailed version of it and clicking it twice either expands an even more detailed representation or collapses it again. Clicking on symbols in s-expressions highlights all other symbols with the same name.
