Knowledge base creation was the most challenging undertaking. Librarians across all departments produced a list of over 100 questions. 2. List included questions stated in natural language and questions with similarities. 3. Questions were also obtained from our library FAQ list and from other library websites. 4. Many answers or responses to questions had to be integrated with existing websites and many new answers had to be created. 5. Focus group consisted of 15 end users who were undergraduates, graduate students and faculty. 6. Focus group feedback captured by IntelliResponse was analyzed over a two weeks period (average of two hours per day). 7. Feedback helped to improve existing questions and uncover new content opportunities 8.

For example, it might be possible to collaborate and build a folder of all the possible questions and answers with respect to the question “How do I cite a website?”. It would be possible to link both a web page as well as a short video explaining how to do this. Impact on the Library • • • • Provision of better quality and more consistent answers to questions Unanswered questions are captured and can be used to create new knowledge Reveals implied customer needs without surveys or focus groups Reduction of staff/librarian’s time to: 1. answer emails 2. take phone calls 3. chat 4. navigate library website Impact on Perceptions of the Library • Library staff themselves find the knowledge base valuable that even some of them have begun to use it to obtain answers to frequently asked questions. • Enhanced library service – anecdotal evidence favors the system What Have We Learned? • Some of our websites: – may be inaccurate – may need a makeover – could be more user friendly • Our library policies may need revision • Our users wish to have their indepth homework questions answered • Our Intelliresponse knowledgebase will be a continuous WIP.
