The work proposes an innovative model of state structure that combines Adaptive Systems Theory, Game Theory, Graph Theory, and others. The state is redefined as an Adaptive System, and some processes in it are redefined as positive sum games according to Game Theory. A modest introduction to these areas is made for non-specialists. Most of the stat...

Фалшивите философи са хора, които твърдят, че са експерти във философията, но им липсват необходимите знания и разбиране на предмета. Те често представят невярна или подвеждаща информация, подвеждайки хората и предизвиквайки объркване. Фалшивите философи могат да бъдат разпознати по липсата на доверие и склонността им да правят твърдения, без да пр...
The provision of educational services with high quality is a matter of concern to all stakeholders in higher education (academic staff, administration, students, etc.). According to many researchers, student satisfaction is an indicator of service quality in higher education institutions (HEIs), and evaluating the quality of educational and adminis...
The research presents an algorithm for creating a programming language and query language independent software module that handles the task of extracting information from a relational database from a natural language user question. The goal can be achieved through pre-built models describing concepts from the domain area under consideration, manage...
The research is a crossroads in the fields of Informatics and Computational Linguistics and illustrates the understanding and interpretation of texts in natural language by computers. The focus of the research is the presented methodology for describing domain area. In it, the computer is trained with the help of grammar rules and storage (classifi...
The objective evaluation of qualitative indicators requires the extraction and processing of huge amounts of data. The paper aims to propose a model for extracting values of quantitative indicators to a quality evaluation system with the help of natural language analysis. It presents an algorithm and the development of a software module, which use...
It is a healthy diet that creates conditions for human life, ensuring the optimal functioning of all processes in the body. Of course, a healthy diet cannot be a protection against the penetration of infection into the body, but it is the balanced and full-fledged nature of the diet that creates the conditions for the formation of a timely and adeq...
The paper presents a methodology and an application framework (PUAnalyzeThis) that makes use of MeaningCloud API to automatically extract entities, concepts, relations, etc. and calculate scores and grades based on their relevance to a preliminary created topics graph. These topic graphs are either to be created by the teacher or automatically gene...
Support for various aspects of personalization and adaptation of the reviewed tools is not at the desired level of abstraction - very often depends on the specific way in which it is assumed that a learning object will be combined, to build a learning path for going through an e-course, or to achieve learning goals. This document describes an innov...
A model of a software tool for semantic text search and retrieval of information about objects, implemented in Python, is presented. The computer processing of natural user text and understanding of the semantics of the text so that it gives useful answers for the users is a task of the natural language processing, by means of which the results in...
Nowadays, schools use many information systems to automate their activities for different stakeholders' groups-learning management systems, student diary, library systems, digital repositories, financial management and accounting systems, document processing systems, etc. The huge amount of data generated by the users of these systems, led to incre...
The paper presents a chatbot oriented linguistic approach and a software prototype which addresses the need of delivering learning content based on queries in Bulgarian language. Two distinct database query generation approaches are presented, discussed and implemented. Pros and cons for each of them are discussed.
The paper presents an approach to learning and an environment for working with a hybrid visual-text programming language with a special emphasis on the training for future programmers at an early stage. An overview of other visual programming environments and languages is made and the advantages of the hybrid visual-text approach offered in this ar...
