Interacting with Dependencies¶

This component is responsible for managing dependency parses

class corenlp_xml.dependencies.DependencyGraph(element)[source]¶

Dependency graph, models a dependency parse

get_node_by_idx(idx)[source]¶

Stores each distinct node in a dict

Parameters:	idx (int) – the “idx” value of the node
Returns:	the node instance for that index
Type:	corenlp_xml.dependencies.DependencyNode

Accesses links within the graph

Returns:	a list of corenlp_xml.dependencies.DependencyLink instances
Type:	list of corenlp_xml.dependencies.DependencyLink

links_by_type(dep_type)[source]¶

Accesses links within the graph

Parameters:	dep_type (str) – the depency type
Returns:	a list of corenlp_xml.dependencies.DependencyLink instances
Type:	list of corenlp_xml.dependencies.DependencyLink

class corenlp_xml.dependencies.DependencyLink(graph, element)[source]¶

Represents a relationship between two nodes in a dependency graph

dependent[source]¶

Accesses the dependent node

Getter:	returns the Dependent node
Type:	corenlp_xml.dependencies.DependencyNode

Accesses the governor node

Getter:	Returns the Governor node

class corenlp_xml.dependencies.DependencyNode(graph, element)[source]¶

Represents a node in a dependency graph

dependent(dep_type, node)[source]¶

Registers a node as dependent on this node

Parameters:	dep_type (str) – The dependency type node (corenlp_xml.dependencies.DependencyNode) – The node to be registered as a dependent
Returns:	self, provides fluent interface

dependents[source]¶

Gets dependent nodes

Getter:	returns a flat list of all governing nodes
Type:	list of corenlp_xml.dependencies.DependencyNode

dependents_by_type(dep_type)[source]¶

Gets the dependents of this node by a given dependency type

Parameters:	dep_type (str) – The dependency type
Returns:	dependents matching the provided type

governor(dep_type, node)[source]¶

Registers a node as governing this node

Parameters:	dep_type (str) – The dependency type node –
Returns:	self, provides fluent interface
Return type:	corenlp_xml.dependencies.DependencyNode

governors[source]¶

Gets governing nodes

Getter:	returns a flat list of all governing nodes
Type:	list of corenlp_xml.dependencies.DependencyNode

governors_by_type(dep_type)[source]¶

Gets the governors of this node filtered by a dependency type

Parameters:	dep_type (str) – The dependency type
Returns:	governors matching the provided type

classmethod load(graph, element)[source]¶

Instantiates the node in the graph if it’s not already stored in the graph

Parameters:	graph (corenlp_xml.dependencies.DependencyGraph) – The dependency graph this node is a member of element (lxml.ElementBase) – The lxml element wrapping the node
