Class Syntax

Formalisms should define override this nested class with their own, which will specify values for these attributes.

Nested Classes

Sign
A CCG category and its associated semantics: a CCG sign.

ComplexCategory
In the halfspan formalism, complex categories are made up of an argument half category, a slash and a result half category.

AtomicCategory
An atomic category is of the form A-B, where A and B are half categories.

Slash

DummyCategory
hash(x)

Class Methods

[hide private]

is_complex_category(cls, obj)
For the sake of efficiency, override this and don't use isinstance.

source code

is_atomic_category(cls, obj)
For the sake of efficiency, override this and don't use isinstance.

source code

Inherited from FormalismBase.Syntax: is_category

Static Methods

[hide private]

merge_equal_signs(existing_sign, new_sign)
Used when adding equal signs to the same edge in the chart.

source code

pre_generalize_category(category)
When abstracting categories to something general that just represents the structure of the category, we have to do something special with half categories, since the standard abstraction routine expects the children of a complex category to be atomic or complex categories themselves.
