Abstract: [Purpose/Significance]The reference and consultancy services in university libraries could help faculties and students to acquire library resources more effectively.[Design/Methodology]The library of Wuhan University was taken as the study case. According to actual question and answering requirements, the traditional singleform knowledge base was modified and replaced by an integrated knowledge base of multisource data. Meanwhile, knowledge graph was introduced to explore its utilization in reference and consulting services. [Findings/Conclusion]Heterogeneous knowledge base, which is an integration of multiform knowledge, is mainly applicable for three scenarios: library professional consultancy, academic search consultancy and general question and answering. Multitype knowledge storage enables integration and processing of multiscenario business. As an important part of questionanswer system, it achieves the goal of automation and intellectualization of library reference service. [Originality/Value]A semantic network of professional consulting scene for common questions and answers has been developed. Besides, with the use of abundant academic resource in university libraries, associations among entities in academic fields have been established. Finally, the problem of coexistence of structured and unstructured knowledge in library reference and consultancy has been settled, and the knowledge base of intelligent questionanswer system for library reference has been built.
