The correspondence information of the English-Japanese Bilingual Dictionary, contains the correspondence information for each correspondence word. Correspondence word notation is described in the explanation on supplementary information. Included in the correspondence information is the notation of the correspondence word and also other types of information that are related to the correspondence word. The division of the relation between the headword and the correspondence word used in the English-Japanese Bilingual Dictionary are explained below. The relation between the headwords and the corresponding translations is that of equivalence.
Equivalence is sub-divided into 'complete equivalence' and 'partial equivalence'.
If the concepts of the headword and the correspondence word are either identical or very nearly identical, they are said to have 'complete equivalence' and if the concepts of the headword and the corresponding word are partially similar they are said to have 'partial equivalence'. The type or relation between the headword and the corresponding word is not explicitly given in the records of the English-Japanese Bilingual Dictionary. If the specific properties of either the headword or the correspondence word is indicated in the correspondence notation or the correspondence word has representative examples, then the relation is automatically partial equivalence. If such information is not indicated in the notation, then the correspondence between headword and correspondence word has complete equivalence. The correspondence word category contains information regarding the descriptive format of the correspondence word.
