Rebecca Bryant writes: “In 2021, the University of Calgary Libraries in Alberta launched a multilingual reference chatbot by leveraging a commercial product that combines a large language model with retrieval-augmented generation technology. The chatbot is trained on the library’s own web content, including LibGuides and operating hours, and is accessed from the library’s website. Before launch, the implementation team estimated that the chatbot could answer 14%–24% of reference chat questions, but today the chatbot answers about 50% of all questions with a rating of at least 4/5.”
