MODELS AND METHODS FOR CREATING A PERSONAL INFORMATION SERVICE

Abstract

Currently, most software products designed for end-users are characterized by uniformity and visual overload. Application personalization is not a priority among developers due to high costs, implementation complexity, and data limitations. Excessive interface elements and irrelevant notifications lead to user fatigue, negatively impacting their motivation for continued use. This research investigates the problem of creating an effective information service for personal asset management with a focus on individualization. A review of existing services was conducted, and their limitations, particularly the lack of personalization, were identified. The aim of the research was to develop a functional model of a service that considers individual user needs and can be implemented in both full and simplified ("lite") versions. To achieve this goal, a comprehensive user model is proposed, which accounts for various parameters, including basic consumer data, usage experience, needs, personality traits, and concerns. Attention is also paid to modeling a simplified ("lite") version of an assistant application, which will be accessible to a wide range of users due to simple calculation algorithms and the use of the proposed user model. The simplified version retains the basic functionality of the main application but is characterized by lower resource requirements and greater ease of use. The study proposes methods and technologies that ensure the service's functionality based on individual user characteristics. The developed approach allows for the automation of routine operations, minimizing user involvement and reducing the likelihood of errors. A functional model of the service's operation is developed, describing the interaction between different system components. Algorithms for calculating the necessary quantity of goods and predicting the time of the next order are developed, taking into account individual user parameters and external factors. Approaches to software implementation are proposed, and possible technologies and architectural solutions for service implementation are considered, taking into account security and performance requirements. The research results can be used to create practical tools that promote financial literacy and effective personal asset management.
