In customer-facing chatbots, companies are dealing with large amounts of user utterances that need to be clustered according to their inte...

In this paper, we propose an intuitive, training-free and label-free method for intent clustering in conversational search. Current approaches to short text clustering use LLM-generated pseudo-labels to enrich text representations or to identify similar text pairs for pooling. The limitations are...
