General control flow of the new model
The four different types of reversible grammar approaches which are discussed in this work.
A summary of the approaches discussed in relationship to the new approach. The arrows indicate the relationship of most direct influence.
The left dg
directly mirrors the set of atomic constraints expressed in the example -constraint, and the right dg
bears additional constraints. Hence, it is more informative than the left one.
Some of the sub-dgs of the dg
given in figure
The relationship between paraphrases and ambiguities.
The procedure for prediction.
The procedure for passive-completion.
The procedure for active-completion.
The procedure for scanning.
An agenda-based control mechanism.
The procedure that adds new items to the table if they are not blocked.

A trace of parsing the string ``weil peter heute lügen erzählt.'' For explanations of the symbols used see text.
The derivation tree of the example sentence. The labels of the node refer to the names of the rules of the grammar in Appendix A.
A trace of generating from ``weil(heute(erzaehlen(peter,luegen)))''. For explanations of the symbols used see text.
All possible derivation trees admitted by the grammar for the generation example.
The relationship of generated items of the different inference rules.
A trace through parsing of the string ``sieht Peter mit Maria''.
A trace through generation of ``sehen(Peter,mit(Maria))''
The
item sharing
approach using the uniform tabular algorithm. During the different modes the uniform algorithm maintains different agendas and private active items for the different modes. However, passive items are shared by both directions.

using a reversible grammar.
