HTC Specification of Features and Parameters for Feedback

In this example, the user has specified two features to be used by Feedback to create the classification query profile. The first feature is 35 single terms, which must occur in at least three of the top 80 documents retrieved in the collection. The second is 25 co-occuring terms, in any order, which occur within four terms of each other, also occuring in at least three of the top 80 document. The second feature is weighted overall at 1.5 times the first. Many other Feedback parameters are accepted at their default values.
