Logical foundations of object-oriented and frame-based languages
We propose a novel formalism, called Frame Logic (abbr., F-logic), that accounts in a clean and declarative fashion for most of the structural aspects of object-oriented and frame-based languages. Expand

Theory of Generalized Annotated Logic Programming and its Applications
We introduce a new semantics for multivalued logic programming based on ideals of lattices and a model theory for Fitting's bilattice-based logic programming, which until now has been characterized model-theoretically. Expand

Taming the Infinite Chase: Query Answering under Expressive Relational Constraints
This paper introduces expressive classes of TGDs defined via syntactic restrictions: guarded TGDs (GTGDs) and weakly guarded sets of GWGDs. Expand

HILOG: A Foundation for Higher-Order Logic Programming
We describe a novel logic, called HiLog, and show that it provides a more suitable basis for logic programming than does traditional predicate logic. Expand

F-logic: a higher-order language for reasoning about objects, inheritance, and scheme
We propose a database logic which accounts in a clean declarative fashion for most of the “object-oriented” features such as object identity, complex objects, inheritance, methods, etc. Expand

Transaction Logic Programming
An extension of predicate logic, called Transaction Logic, is proposed, which accounts in a clean and declarative fashion for the phenomenon of state changes in logic programs and databases. Expand

Querying object-oriented databases
We present a new query language, henceforth referred to as XSQL, that incorporates fea tures not found in earlier languages. Expand

D16.1v0.2 The Web Service Modeling Language WSML
We introduce the Web Service Modeling Language WSML which provides a formal syntax and semantics for the Web Service Modeling Ontology WSMO. WSML is based on different logical formalisms, namely,Expand
