        <p>В условиях роста конкуренции на рынке социальных сетей возрастает потребность в инструментах персонализированной рекомендации контента, способных повысить вовлеченность пользователей. Традиционные подходы к построению рекомендательных систем, основанные на коллаборативной фильтрации или контентной фильтрации, имеют ограничения в задачах рекомендации сообществ, где важны как структура социальных связей, так и семантическое описание групп. Данная статья направлена на исследование гибридной модели рекомендательной системы, сочетающей графовые нейронные сети и признаковое описание пользователей и сообществ. Модель интегрирует информацию о взаимодействиях пользователей с группами в виде графа, текстовые эмбеддинги описаний сообществ, полученные с помощью трансформерных моделей, а также числовые и категориальные признаки групп и пользователей. Результаты исследования демонстрируют существенное преимущество предложенного подхода по сравнению с базовыми методами. Проведен сравнительный анализ модели с рандомными рекомендациями и рекомендациями самых популярных групп. Он показывает улучшение метрики MAP@3 в 3,89 раза относительно рекомендации популярных групп и в 4045,9 раз относительно случайной рекомендации. Исследование базируется на данных социальной сети ОК, включающих информацию о 159 685 пользователях и 54 425 сообществах.</p>

        <p>In the conditions of growing competition in the social media market, there is an increasing need for personalized content recommendation tools that can increase user engagement. Traditional approaches to building recommendation systems based on collaborative filtering or content filtering have limitations in community recommendation tasks, where both the structure of social connections and the semantic description of groups are important. This article is aimed at studying a hybrid model of a recommendation system combining graph neural networks and feature description of users and communities. The model integrates information about user interactions with groups in the form of a graph, text embeddings of community descriptions obtained using transformer models, as well as numerical and categorical features of groups and users. The results of the study demonstrate a significant advantage of the proposed approach compared to baseline methods. A comparative analysis with popularity baseline and random baseline shows an improvement in the MAP@3 metric by 3.89 times relative to recommending popular groups and by 4045.9 times relative to random recommendation. The study is based on data from the OK social network, including information about 159,685 users and 54,425 communities.</p>
