Describing of spatio-temporal relationship of objects in object-attribute databaseThe research goal was initially to develop a network (graph) database (DB) of wide applicability for
representing the meaning obtained from a text in a natural language (general DB). Since the meaning
descriptions of the physical world are often encountered in texts, it was required to separate the DB
part (named the physical DB) intended to describe the spatio-temporal and cause-effect relationships
between objects. The article draws attention to this part of DB because it can be used not only in NLP
but also in many other areas: automatic systems of mobile technical objects for orientation in space,
virtual reality, etc. The physical DB describes the physical world from the standpoint of subjective
perception by a person or a technical object. The object-attribute approach to the data structure underlies
the general and physical DB. An organization principle and a rigid format were developed for
the general DB, and the information search technology and a principle for obtaining new information
on the basis of the already existing information are additionally developed for the physical DB. The
physical DB can describe practically all possible characteristics of objects and relations between objects
in the real world: relative position of objects, direction, shapes and dimensions of objects, metrics,
relationships between cause and effect. The real world perception subjectivity is ensured by the
application of the theory of fuzzy sets and linguistic variables.

Implementation of automata computing paradigm in object-attribute basis
The article describes implementation (hardware and software) of computing system in automatic
paradigm based on object-attribute (OA) computer system belonging to the class of dataflow machines.
OA-computer is the system of functional unit (FU) collaborating each other. FU is hardware of software
unit. The system named OA-automation emulate behavior of automation. It is discussion of necessary
FU types and FUs cooperation of OA-automation. It is discussion the developed implementation of different
classes of automata (deterministic, nondeterministic, abstract, structural), the implementation of
automatic decomposition (nested and called slot automata) and systems of concurrent automata. The
article involve describing developed formal models of automation decomposition. The implementation
of automatic paradigm on OA-basis widen field of application of OA-approach to computing system
organization by automatic control system, compiler, language semantics analysis system and etc.
The implementation of automation decomposition simplify development of complex automata system.
