I'm happy to announce the release of What's Wrong With My NLP? 0.1.2: a visualizer and graphical diff for NLP problems, such as dependency parsing, semantic role labeling, chunking or NER. I'm sure many people have their own version of such a thing, but for those who haven't it may be useful. It is written in Java and licensed under the GPL v2. To download, go to
http://whatswrong.googlecode.com
Some of its features are:
* 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 graphs to your system output (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 on a path between certain tokens. * Search corpora for sentences with certain attributes, 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 * Export to EPS
I'd be happy about any kind of feedback, Sebastian
