Conflation Methods Conflation methods vary in how they are done, what the end results are, and how effective they are.
Table lookup is impractical due to the required table size.
There is at least a little saving of space. Effectiveness effects are equivocal, perhaps confounded by the many variables that differ between tests, or situation dependent. Collection effects may be significant, and interact with methods. Truncation is probably not worthwhile. A number of algorithms give similar performance.
