Research and Development Workstation Environment: the new class of Current Research Information Systems
Against the backdrop of the development of modern technologies in the field
of scientific research the new class of Current Research Information Systems
(CRIS) and related intelligent information technologies has arisen. It was
called - Research and Development Workstation Environment (RDWE) - the
comprehensive problem-oriented information systems for scientific research and
development lifecycle support. The given paper describes design and development
fundamentals of the RDWE class systems. The RDWE class system's generalized
information model is represented in the article as a three-tuple composite web
service that include: a set of atomic web services, each of them can be
designed and developed as a microservice or a desktop application, that allows
them to be used as an independent software separately; a set of functions, the
functional filling-up of the Research and Development Workstation Environment;
a subset of atomic web services that are required to implement function of
composite web service. In accordance with the fundamental information model of
the RDWE class the system for supporting research in the field of ontology
engineering - the automated building of applied ontology in an arbitrary domain
area, scientific and technical creativity - the automated preparation of
application documents for patenting inventions in Ukraine was developed. It was
called - Personal Research Information System. A distinctive feature of such
systems is the possibility of their problematic orientation to various types of
scientific activities by combining on a variety of functional services and
adding new ones within the cloud integrated environment. The main results of
our work are focused on enhancing the effectiveness of the scientist's research
and development lifecycle in the arbitrary domain area.Comment: In English, 13 pages, 1 figure, 1 table, added references in Russian.

Distributional semantic modeling: a revised technique to train term/word vector space models applying the ontology-related approach
We design a new technique for the distributional semantic modeling with a
neural network-based approach to learn distributed term representations (or
term embeddings) - term vector space models as a result, inspired by the recent
ontology-related approach (using different types of contextual knowledge such
as syntactic knowledge, terminological knowledge, semantic knowledge, etc.) to
the identification of terms (term extraction) and relations between them
(relation extraction) called semantic pre-processing technology - SPT. Our
method relies on automatic term extraction from the natural language texts and
subsequent formation of the problem-oriented or application-oriented (also
deeply annotated) text corpora where the fundamental entity is the term
(includes non-compositional and compositional terms). This gives us an
opportunity to changeover from distributed word representations (or word
embeddings) to distributed term representations (or term embeddings). This
transition will allow to generate more accurate semantic maps of different
subject domains (also, of relations between input terms - it is useful to
explore clusters and oppositions, or to test your hypotheses about them). The
semantic map can be represented as a graph using Vec2graph - a Python library
for visualizing word embeddings (term embeddings in our case) as dynamic and
interactive graphs. The Vec2graph library coupled with term embeddings will not
only improve accuracy in solving standard NLP tasks, but also update the
conventional concept of automated ontology development. The main practical
result of our work is the development kit (set of toolkits represented as web
service APIs and web application), which provides all necessary routines for
the basic linguistic pre-processing and the semantic pre-processing of the
natural language texts in Ukrainian for future training of term vector space
models.Comment: In English, 9 pages, 2 figures. Not published yet. Prepared for

OntoChatGPT Information System: Ontology-Driven Structured Prompts for ChatGPT Meta-Learning
This research presents a comprehensive methodology for utilizing an
ontology-driven structured prompts system in interplay with ChatGPT, a widely
used large language model (LLM). The study develops formal models, both
information and functional, and establishes the methodological foundations for
integrating ontology-driven prompts with ChatGPT's meta-learning capabilities.
The resulting productive triad comprises the methodological foundations,
advanced information technology, and the OntoChatGPT system, which collectively
enhance the effectiveness and performance of chatbot systems. The
implementation of this technology is demonstrated using the Ukrainian language
within the domain of rehabilitation. By applying the proposed methodology, the
OntoChatGPT system effectively extracts entities from contexts, classifies
them, and generates relevant responses. The study highlights the versatility of
the methodology, emphasizing its applicability not only to ChatGPT but also to
other chatbot systems based on LLMs, such as Google's Bard utilizing the PaLM 2
LLM. The underlying principles of meta-learning, structured prompts, and
ontology-driven information retrieval form the core of the proposed
methodology, enabling their adaptation and utilization in various LLM-based
systems. This versatile approach opens up new possibilities for NLP and
dialogue systems, empowering developers to enhance the performance and
functionality of chatbot systems across different domains and languages.Comment: 14 pages, 1 figure. Published. International Journal of Computing,

Hybrid e-rehabilitation services: SMART-system for remote support of rehabilitation activities and services
One of the most effective solutions in medical rehabilitation assistance is remote patient / person-centered rehabilitation. Rehabilitation also needs effective methods for the “Physical therapist – Patient – Multidisciplinary team” system, including the statistical processing of large volumes of data. Therefore, along with the traditional means of rehabilitation, as part of the “Transdisciplinary intelligent information and analytical system for the rehabilitation processes support in a pandemic (TISP)” in this paper, we introduce and define: the basic concepts of the new hybrid e-rehabilitation notion and its fundamental foundations; the formalization concept of the new Smart-system for remote support of rehabilitation activities and services; and the methodological foundations for the use of services (UkrVectores and vHealth) of the remote Patient / Person-centered Smart-system. The software implementation of the services of the Smart-system has been developed

example on the stage of requirements specification or EFT-stage. An important feature of this project is using the
advanced multi-dimensional access method for organizing the information base of the Virtual laboratory
Transfer function for a controllable pitch propeller with added water mass
The relevance of this study lies in the fact that it presents a mathematical model of the dynamics of the propulsion system of a ship that takes into consideration the mass of water added to it. The influence of this phenomenon on the resonant frequencies of the propeller shaft is examined, and a transfer function for a controllable-pitch propeller is obtained for various operating modes. The purpose of the study is to improve the calculation of the dynamic operating modes of a controllable-pitch propeller by examining the features of a visual models. The VisSim software package is used in the study. A visual model is developed that considers the influence of the rotational speed on the value of the rotational inertia attached to the variable-pitch screw of the mass of water, and a special transfer function is proposed. The study shows that a transfer function of this type has a loop enabling negative feedback. An analysis of the operation of the propeller shaft at its resonant frequency is conducted based on the application of frequency characteristics using the transfer functions obtained. We show that in the low-frequency region, a consideration of the added rotational inertia using the proposed transfer function leads to a significant difference compared to the result obtained with the existing calculation method
