In this work we consider different types of semantic dictionaries and describe the problems of their construction. We also describe the ontological-semantic rules proposed for ontology modification. We provide examples of such rules and describe the process to generate them. The software implementation of ontology modification using ontological-sem...

... In this paper on the basis of the personal results obtained before in the area of sensor networks construction [1,[3][4][5][6], semantic analysis and question-answering systems [7][8][9] we introduce a new notion of «geospace question-answering sensor networks» (GQASN) that means a distributed network which monitors ambient environment parameters applying the data from geospace and allowing nodes to answer defined types of natural language questions as well. ...
The work is aimed at formalizing the implementation of the steps of the new method "seeding programming" focused on solving some optimization problems. Michelangelo told that there is a statue in every stone and all that is needed is to be able to remove all unnecessary and to take the statue to light. Based on Michelangelo's statement in the proposed method we search for such a sequence of elements to remove from the original space ("stone"), which will lead to the formation of a set of remaining undeleted elements with the desired objective function. Initial elements of the search space can either be specified, or they can be searched using special covering algorithms. To search for the sequence of elements to remove from the search space we suggest to use search agents which during work form and use shared global memory.

A basic framework for the elaboration of a model of the dynamics of phosphorus in Cuban coastal ecosystems is presented. We start from a 0-dimensional model, which includes several physical, chemical and biological processes depending only on time. In this, first a relatively isolated ecosystem was considered, and then polluting loads from runoff were included. Then the vertical space variable was introduced, given the importance of the interaction of phosphorus with the bottom in many coastal ecosystems. This resulted in a 1-dimensional model of predominantly thermo-hydrodynamic model, coupled with a model of radiative transfer in atmosphere and ocean. The thermo-hydrodynamic frame of the model consists of a system of three partial differential equations whose solutions were found and turned out to be well behaved from a mathematical point of view. A preliminary application to a case study was done and analyzed. They were able to lay the foundations for the preparation of a Cuban hydrodynamic model.
