In intelligent computing services， data analysis and processing are provided for the service consumer by the service provider through Internet， and a learning model is established to complete intelligent computing function. Due to the lack of effective communication channels between service providers and service consumers， as well as the fuzzy and messy requirement descriptions of the service consumer feedback， there is a lack of a unified service requirement acquisition method to effectively analyze， organize and regulate the continuously changing requirement of users， which leads to the failure of intelligent computing services to make a rapid improvement according to the user’s requirements. Aiming at the problems of continuity and uncertainty of requirement changes in service development， a requirement acquisition method for intelligent computing services was proposed. The application feedback and questions of intelligent computing services were firstly obtained from Stack Overflow question and answer forum. Then， the knowledge classification and prioritization were performed on them by using different learning models （including Support Vector Machine （SVM）， naive Bayes and TextCNN） according to the types of requirements concerned by the service consumer. Finally， a customized service requirement template was used to describe the requirements of intelligent computing services.
