class CCGSyntaxEnumerativeSearcher

Bases: CCGSyntaxSearcherBase

Enumerative searcher for syntax types.

Methods

gen([max_depth, allow_functor_type])

Generate a list of candidate syntax types.

Attributes

syntax_system

The syntax system.

__init__(syntax_system, starting_symbols=('S',))

Initialize the searcher.

Parameters:

• syntax_system (CCGSyntaxSystem) – the syntax system, containing all primitive and conjunction syntax types.

• starting_symbols (Iterable[str]) – the root primitive symbol for candidate syntax types.

__new__(**kwargs)

gen(max_depth=3, allow_functor_type=False)

Generate a list of candidate syntax types.

Parameters:

• max_depth (int) – The maximum depth of the syntax tree.

• allow_functor_type (bool) – Whether to allow functor types during composition. When this is set to False, the function will not generate any syntax types that contains functor-typed arguments. For example S/(NP/NP).

Returns:

A list of candidate syntax types.

Return type:
