udapi.block.zellig_harris.enhancedeps module

class udapi.block.zellig_harris.enhancedeps.EnhanceDeps(zones='all', if_empty_tree='process', **kwargs)

Bases: Block

Identify new relations between nodes in the dependency tree (an analogy of effective parents/children from PML). Add these new relations into secondary dependencies slot.

process_node(node)

Enhance secondary dependencies by application of the following rules: 1. when the current node A has a deprel ‘conj’ to its parent B,

create a new secondary dependence (B.parent, B.deprel) to A

2. when the current node A has a deprel ‘conj’ to its parent B, look at B.children C when C.deprel is in {subj, subjpass, iobj, dobj, compl} and there is no A.children D such that C.deprel == D.deprel, add a new secondary dependence (A, C.deprel) to C

Parameters:

node – A node to be process.

udapi.block.zellig_harris.enhancedeps.echildren(node)

Return a list with node’s effective children.

Parameters:

node – An input node.

Returns:

A list with node’s effective children.

Return type:

list

udapi.block.zellig_harris.enhancedeps.enhance_deps(node, new_dependence)

Add a new dependence to the node.deps, but firstly check if there is no such dependence already.

Parameters:

• node – A node to be enhanced.

• new_dependence – A new dependence to be add into node.deps.

udapi.block.zellig_harris.enhancedeps.eparent(node)

Return an effective parent for the given node.

The rule for the effective parent - when the current node A has a deprel ‘conj’ to its parent B, return B.parent, otherwise return A.parent.

Parameters:

node – An input node.

Returns:

An effective parent.

Return type:

udapi.core.node.Node
