As argued above, it might be a good idea to avoid ``generate and test'' as supported by a chart parser. Since we are concerned with constraint programming, the idea would be to use ``propagate and distribute'' instead.
Following this idea, we should restricted the form constituents (previously stored as edges of a chart) by constraints rather than generated them by grammar rules. In fact, the dependency parser to be presented does exactly this: Traditional grammar rules are replaced completely in favor of two kinds of constraints:
role dependency constraints
word order constraints.
