This application is useful when editing TAN-A-lm files. Very frequently, when using local language resources to generate a fresh TAN-A-lm file for a class-1 file, the results are very dirty. Cleaning up the file normally involves deleting many entries, so that alternative options' certainty rates no longer add to a whole 1.0. Or perhaps certainty has not even been set, and it needs to be added. This application will refresh the certainty rates of a TAN-A-lm, making it more useful for applications that rely on certainty rates for scoring, such Tangram. A second way this may be useful is for edits to language-specific TAN-A-lm file, where you might be recalibrating the certainty values of some lm combinations. Perhaps a wordform that has ten lexicomorphological resolutions, each one with a detailed @cert value. You want to promote one of the options as being slightly more probable, but you do not want to recalculate all the values so they add to 1.0. You can increase or decrease the @cert value of an option, then run the file through this application to recalibrate all entries so they add to 1.0 certainty. any TAN-A-lm file none the TAN-A-lm file with certainty recalibrated none Edited, prepared for TAN 2021 release.
