摘要: The overall goal of this paper is to devise a flexible and declarative query language for specifying or describing particular knowledge discovery scenarios. We introduce one such language, called IQL. IQL intended as general, descriptive, declarative, extendable implementable inductive querying that supports the mining both local global patterns, reasoning about queries processing using logic, well incorporation new primitives solvers. an extension tuple relational calculus includes functions primitives. integrates ideas from several other programming languages, pattern matching function typing. hope it will be useful specification integrating data systems principles.
