Abstract

This paper discusses the differences in query reformulation for mobile phone, tablet and desktop devices by mining the transaction log data of a library OPAC. We aimed to analyze the impacts of different devices on user search behavior and provide constructive suggestions for the development of library OPACs on different devices. Based on transaction logs which are 9GB in size and contain 16,140,509 records of a university library OPAC, statistics is used to analyze the differences in query reformulation on different devices in terms of two aspects: query reformulation tactics and query reformulation complexity. The results found that as reformulation times increased, the differences between query reformulation among different devices decreased. Mobile-side libraries need to optimize user interfaces, for example by setting web page labels and improving input capabilities. Desk-side libraries can add more suggestive content on the interface.
