Question

________ phase merges the counts for unique ngrams or ngram fragments across multiple documents.

a)CollocCombiner

b)CollocReducer

c)CollocMerger

d)None of the above

Answer 1

Answer:-  A

Reason:-  The combiner treats the entire GramKey as the key and as such, identical tuples from separate documents are passed into a single call to the combiner's reduce method, their frequencies are summed and a single tuple is passed out via the collector.
