Abstract
In a technology company, quality of customer service that involves providingtroubleshooting assistance and advice to customers is a crucial asset.Often, insights from historical customer service data are used to make decisions related to future product offerings. In this paper, we address the challenging problem of automatic assignment of product names and software version labels to customer Service Requests (SRs) related to BLIND, a company in the networking domain.We study the effectiveness of state-of-the-art Large Language Models (LLMs) in assigning the correct product name codes and software versions from several possible label options and their “non-canonical” mentions in the associated SR data. To this end, we frame the assignment as a multiple-choice question answering task instead of conventional prompts and devise, to our knowledge, a novel pipeline of employing a classifier for filtering inputs to the LLM for saving usage costs. On our experimental dataset based on real SRs, we are able to correctly identify product name and software version labels when they are mentioned with over 90% accuracy while cutting LLM costs by ~40-60% on average, thus providing a viable solution for practical deployment.
