Do you have implementation of purity in java?
In this paper (http://arxiv.org/abs/1306.0271), purity is introduced as one of the ranking measures
for phrases. A phrase is pure in topic t if it is only frequent in documents (here documents refer to
titles) about topic t and not frequent in documents about other topics. For example, 'query
processing' is a more pure phrase than 'query' in the Database topic.
Thanks
