| 词条 | Unique name assumption |
| 释义 |
The unique name assumption is a simplifying assumption made in some ontology languages and description logics. In logics with the unique name assumption, different names always refer to different entities in the world.[1] It was included in Ray_Reiter's discussion of the Closed-world_assumption often tacitly included in Database Management Systems (e.g. SQL) in his 1984 article "Towards a logical reconstruction of relational database theory (in M.L. Brodie, J. Mylopoulos, J. W. Schmidt (Hrsg.), Data modelling in Artificial Intelligence, Database and Programming Languages, Springer 1984, S. 191–233). The standard ontology language OWL does not make this assumption, but provides explicit constructs to express whether two names denote the same or distinct entities.[2][3]
