Ivan A. Pisarev, Elena E. Kotova, Andrey S. Pisarev · 2019
The article discusses a method for constructing scenarios in an adaptive analytical information system for classifying objects and their movement trajectories in real time based on processing information from a large number of spatially separated information sources (sensors) and analyzing dynamic arrays of distributed multidimensional data under conditions of uncertainty. Examples of scenarios that use statistical, interval, fuzzy and stochastic methods for describing uncertainty are given. When developing scenarios for adaptive data processing and analysis, integrated ontologies of the “hydroacoustics” field of knowledge, ontologies of signal processing methods, image processing methods and data analysis methods are used. Creation of scenarios for automated processing of multidimensional spatial-temporal data is carried out in the OntoMASTER network software environment based on semantic Web standards. To support scientific research, a dynamic scripting interface and their testing in a simulator environment is implemented. The learning environment based on the knowledge base is intended for training and retraining of personnel. The results of the work can be applied both in scientific research and in the process of teaching students.
