原始语种摘要: Purpose(#br)The study focused on online public access catalog (OPAC) users’ cross-device search behavior. The purpose of this paper is to understand the characteristics of cross-device OPAC searches, and to identify query reformulation (QR) patterns during device transitions. (#br)Design/methodology/approach(#br)The transaction log from a university library, spanning six months, was used to conduct the quantitative analysis. The query vocabulary richness, which refers to the average number of unique words each query contains in a search session, can evaluate query diversity, and contribute to the analysis of QR. (#br)Findings(#br)The results show that PC-PC transition is the most important pattern of device transition. The time interval of device transition was different to the time...
