Development and Implementation of Technology for Creating a Wide Class of Applications Such as Chatbots Based on Formal Models

Abstract

The article proposes the concept of a platform for the development, accumulation and use of specialized applications – bots that automate functions related to informing, ordering and fulfilling orders, the implementation of multi-stage processes using capabilities of social networks and messenger programs. Individual stages of these processes depend on various circumstances, most important and influential being events and features of participants who are abonents of the said social networks and users of messengers. Differences in such features and circumstances affect complexity, structure and overall composition of the whole application, determining the entire end-to-end flow of the development process. Due to that, creation of the said applications require thorough planning and coherent, thought-out approach to conduction of design work on stages crucial to the whole multistage process. Based on those assumptions, a general approach to creating bots using formal models is described, including usage of state machines, logical models, and descriptions of business processes. Diagram specifications are built based on analysis of business processes to facilitate the conduction of implementation of proposed bot applications. In the platform implementation plan, the practical implementation of the component is proposed, which ensures the construction of the logic for processing user actions within the implementation of the given business process in accordance with the diagram specification. An example of using a practical implementation of a component to create a bot is described to better illustrate peculiarities and features of individual process stages, implementation of bot applications and flow of development as a whole. Development of a platform that is to be composed of such applications is envisioned.
