Class GraphVisualiser

java.lang.Object
  sem.graphvis.GraphVisualiser

public class GraphVisualiser
extends java.lang.Object

An application for visualising the graphs. Take a look at sem.examples.VisualiseGraphs for sample code on how to run it.

Navigate through sentences using Z and X, iterate over alternative parses (if available) using A and S.

An experimental feature for editing the graphs is also included (has to be enabled when initialising the visualiser).

The following commands are supported:

• next / n - next sentence
• prev / p - previous sentence
• goto <i> - jump to <i>th sentence (e.g., goto 100)
• add <t> <i> <j> - add an edge labeled <t> from the <i>th node to the <j>th node
• del <i> <j> - delete the edge from the <i>th node to the <j>th node
• save <file> - save the graph in TSV format into <file>
