Они позволяют не только общаться с другими пользователями, но и включают в себя функционал, помогающий создавать автоматических собеседников, автоматизирующих отдельные бизнес-процессы либо удовлетворяющих информационные потребности пользователей. В статье рассматривается узкоспециализированная вопросно-ответная система, которая использует инфраструктуру, предоставляемую современными мессенджерами для обмена сообщениями и предназначенную для информационной поддержки абитуриентов, поступающих в университет. В процессе разработки системы был накоплен корпус характерных вопросов абитуриентов, а также разработана модель, которая позволяет осуществлять поиск близких вопросов по этому корпусу. При этом абитуриент может формулировать свои вопросы на естественном языке без изучения предварительно заданных шаблонов или специальных правил построения сообщений. Для получения ответов на вопросы, которых нет в корпусе системы, привлекаются специалисты приемной комиссии, имеющие свой интерфейс. Система была реализована с использованием современных облачных технологий, предоставляемых компанией Amazon. Среди них бессерверные (serverless) вычисления и NoSQL-базы данных. Для этого была разработана архитектура сервиса, удовлетворяющая этой модели вычислений. Поскольку система может оперировать с чувствительными данными, включая персональные данные, а также предоставлять персонализированный сервис, были проанализированы методы обеспечения безопасности системы, а также подходы к авторизации пользователей. В настоящее время система проходит тестирование и оценку используемых алгоритмов информационного поиска.</p></abstract><trans-abstract xml:lang="en"><p>There is an increasing interest to the instant messaging applications, messengers. These applications allow us to interact with other users and include a functionality that can help us to implement bots that automate various business processes or provide information services. In this paper, we consider a specialized question answering system that uses today’s messaging services infrastructure to support university applicants. We gathered a corpus of applicants questions throughout two years and developed an information retrieval model that helps us to find similar questions in the corpus. Applicants can type their questions using a natural language without any formal requirements to phrase construction or using special templates. If the system is unable to find a relevant answer, the user can directly address the question to representatives of the university. The system was implemented with the use of modern cloud services that are provided by Amazon. We used serverless computations and NoSQL data bases, so we had to develop an architecture of the system in that way. Since the system contains sensitive personal data and provide personalized service, we must focus our attention on security. We proposed the means that must improve the safety of the system, more specifically, authentification process that can be used without the explicit use of personal data, however, this is a future work. At present we test our system and evaluate its quality of information retrieval.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вопросно-ответная система</kwd><kwd>мессенджер</kwd><kwd>информационный поиск</kwd><kwd>облачные системы и сервисы</kwd><kwd>безопасность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>question answering system</kwd><kwd>messenger</kwd><kwd>information retrieval</kwd><kwd>cloud systems and services</kwd><kwd>security</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке проекта «Моделирование и анализ информационных систем» (инициативный проект ЯрГУ № АААА-А16-116070610022-6)</funding-statement><funding-statement xml:lang="en">This work was supported by initiative project of P.G.
