What's Wrong With My NLP?: A visualizer for Natural Language Processing problems.

Features

• (Jointly) visualize
• syntactic dependency graphs
• semantic dependency graphs (a la CoNLL 2008)
• Chunks (such as syntactic chunks, NER chunks, SRL chunks etc.)
• Compare gold standard trees to your generated trees (e.g. highlight false positive and negative dependency edges)
• Filter trees and visualize only what's necessary, for example
• only dependency edges with certain labels
• only the edges between certain tokens
• Search corpora for sentences with certain attributes using powerful search expressions, for example
• search for all sentences that contain the word "vantage" and the pos tag sequence DT NN
• search for all sentences that contain false positive edges and the word "vantage"
• Reads
• CoNLL 2000, 2002, 2003, 2004, 2006 and 2008 format
• Lisp S-Expressions
• Malt-Tab format
• markov thebeast format
• Export to EPS

How to run

Download the jar file and execute

java -jar whatswrong-x.y.z.jar

Screenshots

CoNLL 2008

This is a fraction of a semantic dependency graph that compares a gold labelling to a system labelling. The red edges are false positives, the blue ones false negatives and the black ones are matches:

CoNLL 2003

This shows the comparison of two shallow parses and two NER labellings (again false positives are red, false negatives are blue and matches are black):

Documentation

Most of the functionality can hopefully be understood by just playing around with the example graph. For source documentation check the JavaDoc.
