A method of filtering content in a discovered topic. In one embodiment, a method for filtering content in a discovered topic is comprised of preprocessing querying data. The querying data has caused retrieval of a collection of documents. The collection of documents includes documents containing subject matter related to said querying data. The collection of documents also includes documents containing subject matter extraneous to said querying data. The querying data is clustered. Clustering of the querying data enables the discovered topic to be identified. The collection of documents are postfiltered. The postfiltering of the collection of documents generates a collection of documents having the related subject matter, and extraneous subject matter is excluded.
