A proof-theoretic framework for nonmonotonic reasoning and logic programming
This paper proposes a general proof-theoretic framework, where negative literals in a query are proved by a new mechanism of negation-as-failure. This new mechanism handles nonground negative literals and thus...

An optimal parallel algorithm for the vertical segment visibility reporting problem
In this paper, we present a parallel algorithm for solving the all-pairs vertical segment visibility reporting (SVR) problem. Given a set S={S 0, S 1,...,S n−1} of disjoint vertical segments in the plane, the SVR...

Unordered tree contraction
The tree contraction problem is for reducing a rooted tree to its root by a sequence of independent vertex removals. All of the previous research works are concentrated on ordered rooted tree whereas in this p...

Incremental database design revisited
Three new classes of database schemes are defined. The class of weakly independent schemes is a generalization of independent schemes in a centralized environment. The classes of expansion-chased schemes and s...

Inheritance conflicts in object-oriented systems
Inheritance conflicts in class hierarchies are avoidable through design that considers application semantics. An algorithm, in the form of IF-THEN statements, is presented that resolves any name conflicts in c...

Improving integrity constraint checking for stratified deductive databases
Integrity checking for stratifiable deductive databases has been studied by many authors. In order to handle recursive relations, most of these methods adopt update driven approach to validate each given const...

Efficient storage structures for temporal object-oriented databases
Automatically managing the evolutionary histories of both schema and data is an attractive feature for temporal object-oriented database management systems (OODBMS). It can make the temporal OODBMSs more suita...

A normal form object-oriented entity relationship diagram
A normal form object-oriented entity relationship (OOER) diagram is presented to address a set of OO data modelling issues, viz. the inability to judge the quality of an OO schema, the presence of inheritance ...

The design of an integrated information system
This paper discusses a systematic approach of how to link hypertext, databases and a data modelling tool together to support users' complex application definitions and maintenance. The salient features of this...

LearnMedia: A co-operative intelligent tutoring system for learning multimedia
Intelligent Tutoring Systems (ITSs) have become increasingly important for enabling students to understand and solve specific problems. It is realised that today's state-of-the-art ITSs still lack the collabor...

An algebra for a temporal object data model
In this paper, we present a temporal object data model, which has been adapted from the unified model of OODB and RDB in UniSQL/X so that a time dimension can be easily added to form temporal relational-like c...

Toward a unified data model for large hypermedia applications
The major problem in using the current hypermedia mechanisms to support large applications is that the node and link structure is too simple to reveal the semantic connections among documents, and in particula...

Refined termination decision in active databases
Termination decision in trigger systems is important to make sure that any rule execution does not result in an infinite loop. In general, it is an undecidable task. Several recent works have been proposed to ...

Qualitative spatial relationships representation IO&T and its retrieval
We present in this paper, a qualitative spatial relationships representation scheme called IO&T which combines fuzzy Intrinsic Orientation and Topological spatial relationships, and a similarity measure based ...
