From: A novel alignment-free method for detection of lateral genetic transfer based on TF-IDF

Performance of TF-IDF with variation post-LGT and deletion.
Precision (A) decreases with variation post-LGT, but is unaffected by deletion. Recall (B) decreases greatly with variation post-LGT and slightly with deletion. Variation between groups is 0.1 and variation within groups is 0.01. Sequence length is 300,000 nt.
