Background of the Program
• commenced in August 2007
• took approximately 200 hours over seven
months
• 10 hours of training of 1 professional librarian
• creation of a knowledge base of about seventy
questions
• focus group testing on February 12, 2008
• product was launched March 18, 2008
Knowledge Base
Tasks
1. 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. Work in progress

to navigate library website, Q&A or FAQ solutions
Benefits to the Information Community
Introducing a model:
• for library self-service
• that permits natural language query
• that can make it possible for libraries to collaborate and build
and share questions and answers in areas such as information
literacy as well as ready reference rather than try to build Q&A
from scratch. 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.
