Product Query Recommendation for Enriching Suggested Q&As

To help customers who are still in the exploration phase, Web search engines and e-commerce websites often provide relevant Q&As in widgets, such as 'People Also Ask' and 'Customers Also Ask Alexa', with additional information. In this work, we propose to enrich this customer experience by rendering related products under each Q&A based on an automated online query recommendation. We define what are the tenets for high-quality query recommendations and explain why this challenge is different from the existing query re-writing, query expansion and keyphrase generation methods. We describe a data collection method which uses customer co-click information on a proprietary website in order to successfully guide our model into generating query recommendations that satisfy all tenets. Offline and online evaluation results demonstrate that our proposed approach generates superior query recommendations and brings much more customer engagement over strong baselines.
