Abstract: Techniques for expanding system capabilities to execute user commands relating to trending topics (e.g., real-time news questions, trending questions, sports questions, game questions, politic questions, etc.) are described. The system gathers data from a variety of sources (e.g., news feeds, social media feeds, RSS feeds, news websites, etc.). The system segments gathered data corresponding to, for example, topic and or entity. The system may only store data corresponding to a topic or entity in a dedicated trending storage if the system receives data corresponding to the topic or entity from a number of different sources satisfying a threshold number of sources. Data in the dedicated trending storage may be maintained using decay models or algorithms. For example, the more often the system receives data corresponding to a topic or entity from one or more sources, the longer the data is maintained in the storage, and vice versa.
