ملخص المقالة :
سیستم‌های توصیه‌گر مبتنی بر جلسه بر اساس رفتار و تعاملات کاربر در یک جلسه، رفتار بعدی یا علاقه کاربر را پیش‌بینی کرده و بر این اساس، آیتم‌های مناسب را به کاربر پیشنهاد می‌دهند. مطالعات اخیر برای ایجاد توصیه‌ها عمدتاً روی اطلاعات جلسه فعلی متمرکز شده‌اند و اطلاعات جلسات قبلی کاربر را نادیده می‌گیرند. در این مقاله، یک مدل توصیه‌گر مبتنی بر جلسه شخصی‌سازی شده با شبکه‌های خودتوجه پیشنهاد می‌شود که علاوه بر جلسه فعلی از جلسات قبلی اخیر کاربر هم استفاده می‌کند. مدل پیشنهادی به منظور یادگیری وابستگی کلی بین همه آیتم‌های جلسه، از شبکه‌های خودتوجه (SAN) استفاده می‌کند. ابتدا SAN مبتنی بر جلسات ناشناس آموزش داده می‌شود و سپس برای هر کاربر، توالی‌های جلسه فعلی و جلسات قبلی به صورت جداگانه به شبکه داده می‌شود و با ترکیب وزنی نتایج رتبه‌بندی حاصل از هر جلسه، آیتم‌های توصیه‌شده نهایی به دست می‌آید. مدل پیشنهادی بر روی مجموعه داده واقعی Reddit در دو معیار دقت و میانگین رتبه متقابل، تست و ارزیابی شده است. مقایسه نتایج حاصل از مدل پیشنهادی با رویکردهای قبلی، توانایی و اثربخشی مدل پیشنهادی را در ارائه توصیه‌های دقیق‌تر نشان می‌دهد.
