Techniques for providing information for presentation at a device are described. In an example, a computer system receives, from a device, a query indicating that item information is requested. The computer system determines a topic for the item information. The computer system determines a sub-topic of the topic, the sub-topic generated based at least in part on a semantic overlap between predefined item attribute refinements and user contributed entries related to the item. The computer system causes the device to present the item information, the topic, and the sub-topic in association with the topic.
