Penn Treebank Playground

On this page you can play around with the search tool for the Penn Treebank.

With the 'Filter' field you can search words for words or even specific tree structures. When searching for words you must set the 'Filter application' field to 'Raw text' and enter you words in the 'Filter' field. These can be either single words or entire strings you wish to search for.

When searching for (sub)trees you must set the 'Filter application' field to 'Tree representation'. You can then enter your tree in bracket notation in the 'Filter' field. If you have problems with writing your tree in a bracket notation you should try it with the info you get when clicking the explanation button.

Note that you may also combine the use of both the word and categorial search in one query.
