Description copied from class: FeatureFactory

This method returns a Collection of the features calculated for the word at the specified position in info (the list of words) for the specified Clique. It should return the actual String features, NOT wrapped in any other object, as the wrapping will be done automatically. Because it takes a PaddedList you don't need to worry about indices which are outside of the list.

Specified by:

getCliqueFeatures in class FeatureFactory<IN extends CoreLabel>

Parameters:

info - A PaddedList of the feature-value pairs

position - The current position to extract features at

clique - The particular clique for which to extract features. It should be a member of the knownCliques list.

Returns:

A Collection of the features calculated for the word at the specified position in info.
