Prompt Templates 5 EXPERIMENTS We showcase the utility of TnT-LLM for two text mining tasks of special interest in today’s LLM era: User intent detection and conversational domain labeling over human-AI chat transcripts. TnT-LLM User intent detection conversational domain labeling 5.1 Data Our conversation transcripts are taken from Microsoft’s Bing Consumer Copilot system, which is a multilingual, open-domain generative search engine that assists users through a chat experience. We randomly sample 10 weeks of conversations from 8/6/2023 to 10/14/2023, with 1k conversations per week for Phase 1, where we perform a random 60%-20%-20% split for “learning” the label taxonomy, validation, and testing respectively. We then sample another 5k conversations per week from the same time range for Phase 2, and apply the same train/validation/test data split. We perform two steps of filtering to ensure the quality and privacy of the data. First, we apply an in-house privacy filter that scrubs all personal information (e.g., addresses, phone numbers) from the original conversation content. Second, we apply a content filter that removes all conversations that contain harmful or inappropriate content that should not be exposed to annotators or downstream analyses. After applying these filters, we obtain 9,592 conversations for Phase 1 and 48,160 conversations for Phase 2. We leverage the FastText language detector [11, 12] to identify the primary language of each conversation, where we find around half of the conversations in our corpus are in English. In the remainder of this section, we will report results on the following datasets: • BingChat-Phase1-L-Multi: The test set used in the taxonomy generation phase, which includes around 2k conversations. • BingChat-Phase1-L-Multi: • BingChat-Phase2-L-Multi: The test set used in the label assignment phase, which includes around 10k conversations. • BingChat-Phase2-L-Multi: Besides the above datasets, we also reserve two separate English-only conversation datasets to perform human evaluations, with the same privacy and content filter applied. • BingChat-Phase1-S-Eng includes 200 English conversations to evaluate label taxonomy. • BingChat-Phase1-S-Eng • BingChat-Phase2-S-Eng includes 400 English conversations to evaluate label assignment. • BingChat-Phase2-S-Eng This paper is available on arxiv under CC BY-NC-ND 4.0 DEED license.
