- 01 Query Autocompletion Proposing full queries from a typed prefix within the gap between two keystrokes, from the most-popular-completion baseline and compressed top-k tries to personalised and generative completion, and the harms of suggesting things people did not ask for.
- 02 Query Entity Recognition and Linking Finding the entity mentions in a two- or three-word query and resolving each to a knowledge-base identifier, under a latency budget measured in milliseconds and with almost no context to disambiguate from.
- 03 Query Intent and Taxonomies The same string can be three different requests, and classifying which one determines whether the right answer is a document, an entity, an action, or a generated response.
- 04 Spelling Correction and Query Segmentation Fixing what the user typed before matching it, where the hard part is not generating candidates but deciding whether the original was wrong at all.
