What's Wrong With My NLP? is visualizer and graphical diff for natural language processing problems. It can jointly display syntactic and semantic dependencies as well as all types of chunk information such as NP, NER, or SRL chunks. It also allows you to compare your system output to a gold standard in order to find the mistakes your system makes. There are numerous ways to filter the graph and only display what is needed. It is also possible to search a corpus for sentences with certain properties using Lucene search expressions. The tool reads all CoNLL shared task formats and exports to EPS.
