XQuery is known to be a powerful XML query language with many bells and whistles. For many common queries we do not need all the expressive power of XQuery. We investigate the eff...

Abstract. We survey some of the main results regarding the complexity and expressive power of Live Sequence Charts (LSCs). We first describe the two main semantics given to LSCs: a...
This paper examines the problem of adding non-deterministic constructs to a declarative database language based on Horn Clause Logic. We revise a previously proposed approach, the...
First-order probabilistic models are recognized as efficient frameworks to represent several realworld problems: they combine the expressive power of first-order logic, which serv...
Abstract. This paper studies the expressive power of finite-state automata recognizing sets of real numbers encoded positionally. It is known that the sets that are definable in th...
The Transformation Model TRM was recently introduced 10 in the literature by Sandhu and Ganta. TRM is based on the concept of transformation of rights. The propagation of access ri...
UML is the de-facto standard language for Object-Oriented analysis and design of information systems. Persistent storage and extraction of data in such systems is supported by dat...
We provide a translation from CTL to Datalog¬ Succ. The translation has the following advantages: a) It is natural. b) It provides intuition to the expressive power of CTL and it...

In 1984, Peter Patel-Schneider published a paper [1] entitled Small can be Beautiful in Knowledge Representation in which he advocated for limiting the expressive power of knowledg...
Both OWL-DL and function-free Horn rules3 are decidable logics with interesting, yet orthogonal expressive power: from the rules perspective, OWL-DL is restricted to tree-like rule...
