Many industries have implemented chatbot application for online custom service. Considering the increasing reference consults and the declining manpower, the university library could take chatbot application as a solution. This study focus on the implemetation and evaluation of chatbot on virtual reference service of university libraries. We inducted the virtual reference literature for the dialouge pattern and question types and choose 78 articles of university library reference service blog to generate 86 intents(dialouge pattern) and 93 entities (134 synonyms) for virtual reference service chatbot. After the implementation, 32 users with the background of the library information science were invited for testing. As the result, the most interactive dialogue topic were ''my search for books'', ''opening hours'', ''pre‐set greetings'', ''study room seats'' and the other library resources. The statistics showed that the scores of information quality and interactivity were significant improvements, while the system quality score was almost significant. In terms of perceptual usefulness and perceived ease of use, two aspects were significantly improved. Users thought virtual reference service chatbot was easy to get starte. It could answer with good quality and could solve to users' needs. Addiotnally, it could save the search time for the user or reduce the access steps. However, the avergage score of user's attitude was improved but not significant, and the avergage score of user's intention was significant lower. The score of Recommendation willingness was low. According to the user feedback, they believed the performance of chatbot. However, they did have more expectation in converating more influently to the chatbot and asking more questions beyoud the reference question template. Overall, the chatrobot application to virtual reference services is extremely feasible. University libraries can use chatbot application to provide virtual reference services and considerate to apply the technology of natural language process in order to solve the information need and raise the satisfaction from users. |
