Mediating off-site electronic reference services: human-computer interactions between librarians and Web mining technology

The Internet enables global dissemination and retrieval of information at any time, as a result, it has a tremendous impact on how libraries provide reference services to this new web-based clientele. One impact is the increase in off-site library users who make in-person reference interviews impossible. To serve this new 'cntele, academic libraries are setting up electronic reference services to meet offsite information needs. This new approach is not without challenges. It requires effective humanmachine connections to provide smooth reference transactions since librarian-patron contact happens solely through computers. The most challenging aspect of providing electronic reference services to off-site users is deciding when patrons need help. If their needs are not detected, many unsuccessful searches will go undiscovered and end-users may never fmd the information they were seeking. To meet this challenge, pertinent information technology is needed to track web traffic patterns and user behavior (e.g. web mining), addressing immediately the difficulties encountered by end-users. The machine's capability to track potentially unsuccessful searches depends on human experts' ability to identify trouble signs, and add value to the electronic transaction experience with their experiences and skills. This paper's emphasis is on human-computer connections relating to reference librarians' application of web mining technology to transfer their experiences and skills from the reference desk to the web environment. It examines web mining techniques and their potential to assist different library functions. A scenario is used to conceptualize a model that can effectively apply web mining technology to perform various functions of electronic reference services. It also proposes a methodology that librarian can adapt in offering mediation during the search at patrons' discretion. The main goal is to provide more seamless electronic reference transactions. Discussion of library professionals' roles in human-computer interactions in the electronic world follows.
