To perform sentence derivation in multi-DB configurations, including deletion of all derived sentences, regeneration of dependency graphs and (repeated) total re-derivatons. Although the window applies to any multi-DB configuration, it is primarily useful for cyclic multi-KB configurations (i.e. where repeated derivations of the same DB is required). 

MAINTAINING THE LIST OF DATABASES INCLUDED IN THE RE-DERIVATION:

The databases (3kb-files) to be included in the re-derivation process are listed in the listbox control.You can add DBs by using the Add Database-button (and remove with the Remove Databases-button). The list of members can be saved as a re-derivation script (xml format) (with the Save as re-derivation script-button). Refer to the rederivation-tag in the pro3_Script.xsd (schema). An existing script can be loaded with the Load re-derivation script-button.

Note that the DBs are re-derived according to the sequence in the list (which thus is of significance).

PERFORMING THE RE-DERIVATION

• Step 1 - Delete all databases' derived sentences-button deletes all derived sentences in each of the DBs in the set.
• Step 2 - Regenerate all databases' derived sentences-button regenerates the dependency graph in each of the DBs in the set.
• Step 1 followed by 2-button performs 1 and 2.
• Step 3 - Run re-derivation cycles-button runs the specified number of total sentence re-derivations in each of the DBs in the sets. The number of cycles is specified in the edit field to the right.
• Step 1 followed by 2 and 3-button performs 1, 2 and 3 above.
• Close-button closes the window.
