Package edu.stanford.nlp.semgraph

This package provides a representation of dependency graphs (normally the collapsed Stanford Dependencies representation) as a graph (backed by the jgrapht graph library.

To create a typed dependency graph, a SemanticGraph from a parse tree,

 import edu.stanford.nlp.trees.semgraph.*;
 ...
 Tree treeParse = processSentence(sentence);
 SemanticGraph depGraph = SemanticGraphFactory.allTypedDependencies(treeParse, true);
 

Interface Summary

Interface	Description
ISemanticGraphEdgeEql	Interface allowing for different routines to compare for equality over SemanticGraphEdges (typed lambdas in Java?)

Class Summary

Class	Description
SemanticGraph	Represents a semantic graph of a sentence or document, with IndexedWord objects for nodes.
SemanticGraphCoreAnnotations	This class collects CoreAnnotations that are used in working with a SemanticGraph.
SemanticGraphCoreAnnotations.AlternativeDependenciesAnnotation	The CoreMap key for storing a semantic graph that was converted using a non-default converter.
SemanticGraphCoreAnnotations.BasicDependenciesAnnotation	The CoreMap key for getting the syntactic dependencies of a sentence.
SemanticGraphCoreAnnotations.CollapsedCCProcessedDependenciesAnnotation	Deprecated. In the future, we will only provide basic, enhanced, and enhanced++ dependencies.
SemanticGraphCoreAnnotations.CollapsedDependenciesAnnotation	Deprecated. In the future, we will only provide basic, enhanced, and enhanced++ dependencies.
SemanticGraphCoreAnnotations.EnhancedDependenciesAnnotation	The CoreMap key for getting the syntactic dependencies of a sentence.
SemanticGraphCoreAnnotations.EnhancedPlusPlusDependenciesAnnotation	The CoreMap key for getting the syntactic dependencies of a sentence.
SemanticGraphEdge	Represents an edge in the dependency graph.
SemanticGraphFactory	Refactoring of static makers of SemanticGraphs in order to simplify the SemanticGraph class.
SemanticGraphFormatter	Defines a class for pretty-printing SemanticGraphs.
SemanticGraphPrinter	This class contains only a main method, which prints out various views of SemanticGraphs.
SemanticGraphUtils	Generic utilities for dealing with Dependency graphs and other structures, useful for text simplification and rewriting.
SemanticGraphUtils.EdgeDiffResult
SemanticGraphUtils.PositionedTree	This is used to uniquely index trees within a Tree, maintaining the position of this subtree within the context of the root.
SemanticGraphUtils.PrintVerticeParams
