public class QuestionKeywordsFilter
extends Filter

A filter that drops a result if the answer string contains a keyword from the question. Useful to eliminate answers that simply repeat the question, e.g. without this filter a likely answer to the question "Who killed JFK?" would be "JFK".

Note that this filter causes problems if a correct answer repeats part of the question, e.g. answers to the question "What are the members of the Kennedy clan?" also contain the keyword "Kennedy".

This class extends the class Filter.
