Knowledge representation is essential for semantics modeling and intelligent information processing. For decades researchers have proposed many knowledge representation techniques...
Logical properties of iterations of relational structures are studied and these decidability results are applied to the model checking of a powerful extension of pushdown systems....
Abstract. We describe simple algebraic and combinatorial characterisations of finite relational core structures admitting finitely many obstructions. As a consequence, we show th...
Automatic table layout is required in web applications. Unfortunately, this is NP-hard for reasonable layout requirements such as minimizing table height for a given width. One ap...
Case-based analysis is a bottom-up methodology for ethical reasoning. In a teaching environment, it can be a useful alternative to top-down methods, such as Kantianism, utilitaria...
