Linked dictionary
Linked dictionary (sometimes is also called pair dictionary) in the @PROMT Family machine translation systems is the dictionary of the reverse direction of translation (for example, for the Russian-English dictionary it is the English-Russian dictionary), linked with the initial dictionary with the purpose of simultaneous updating and correction.
When you add a word or a collocation in the initial dictionary, a new entry is being automatically created in the linked dictionary, the headword of which is the translation equivalent of the source word. Several entries are being created if there are several translation equivalents. The necessary grammatical information is being formed on the basis of rules for the given language pair.
If you update the linked dictionary the initial dictionary is not modified.
The same dictionary may be a linked dictionary for several dictionaries.
The opposite is not true, i.e. one dictionary cannot have several linked dictionaries.
