Brown Corpus Playground
On this page you find an interface for searching a part of the Brown corpus. The Brown corpus contains a POS layer and may be searched for both words and tags
With the 'Start at' and 'End at' fields you may specify an interval of sentences from the corpus to be shown. The 'Word filter' field lets you search for specific words, while the 'Categorial filter' lets you search for specific Part-Of-Speech tags. In both fields you may use the following operators:
- , (comma): functions as an AND operator. Entering several values separated by commas means you will get all sentences returned that contain all these values.
- | (bar): functions as an OR operator. Entering several values separated by bars means you will get all sentences returned that contain either of these values.
- * (star): functions as a wildcard or placeholder. Entering a word with the star attached means you will get all sentences returned containing words that start with the string before the star. For instance, entering 'man*' will not only give you all sentences containing 'man', but also all sentences containg 'many', 'manner', etc. You may also use the star as a placeholder for any word or category. For instance, entering 'at * nn' in the categorial filter will return all sentences that containing the tag 'at' followed by some tag followed by the tag 'nn'.
- - (minus): functions as a negative operator. Entering a word or tag with a minus attached to it's front will specifically not show up in the sentences that are returned. For instance, entering 'man, -woman' will return all sentences containing the word man but lacking the word woman.
Note that you may also combine the use of both the word and categorial search in one query.
