- Abstract:
-
Axiomatic systems and proof methods for temporal logic have so far found relatively few applications in querying language modeling of temporal databases because the standard temporal logic is not recursively axiomatizable. As a result, temporal logic can not use axiomatic systems and proof methods to religiously depict inference and querying of a temporal database. Thus it is necessary to find a replacement for temporal logic which, by axiomatic methods, can become the implement of a syntactic and semantic analysis of temporal querying languages. The Lambek calculus and its categorical grammar as the former and λcalculus as the latter have become those substitutes in this paper, because of the properties of type theory, the comparability between SQL and state sentence, the axiomatic and proof methods of Lambek calculus and λcalculus,and their correspondence by CurryHoward Isomorphism. So, according to the operations of temporality, we built a new axiomatic system used in syntactic analysis which is called concurrence Lambek calculus (LCTQ), and use its categorial grammar to deal with the temporal querying language. Prof theory shows that for protection of computable resources, LCTQ is more regorous and ideal.
