Program Structure

Issue: 1 (The first issue)
A program is usually represented as a word chain. It is exactly a word chain that appears as the lexical analyzer output and is parsed. The work shows that a program can be syntactically represented as an oriented word tree, that is a syntactic program tree, program words being located both in tree nodes and on tree arrows.


Towards Owl-Based Knowledge Representation in Petrology

Issue: 1 (The first issue)
This paper presents our work on development of OWL-driven systems for formal representation and reasoning about terminological knowledge and facts in petrology.


Finite Systems Handling Language (YAFOLL message 1)

Issue: 16 (The sixteenth issue)
The concept a finite multi-carrier algebraic system (FMAS) as well as a language for handling systems such as YAFOLL (Yet Another First Order Logic Language) are introduced. The applicability of such systems to building a mathematical model of a part of reality, i.e. a mathematical structure that can be asked questions about the properties of subject domain objects and processes, is demonstrated.
