Any documentdocument edge whose calculated similarity is below this value will not be given an edge in the network output by this algorithm.
The comparison algorithm is used to calculate the similarity between documents. You may select between the following algorithms:

SørensenSimilarityIndex 
A network file with all documents connected by a weighted edge as calculated by the comparison algorithm if the weight of the was above the threshold value.
The Cosine Similarity comparison algorithm does not preform any real comparison between the terms. It only uses the existence or nonexistence of a term in the set for the calculation.
