DESCRIPTION
Meet "Pixel," the chatbot at the University of Nebraska– Lincoln Library. Artificial intelligence is enabling Pixel and other types of chatbots to be trained and developed to guide and support students navigating the dense library website and complex databases. See Pixel in action and discuss the future of reference services as libraries incorporate artificial intelligence tools. Speakers: DeeAnn Allison, Director, Professor, Computer Operations and Research Services, University of Nebraska-Lincoln and Lorna M Dawes, Lecturer. Learning Community Librarian, University of Nebraska.TRANSCRIPT

Library Research Pixel fits into the University research
mission as an experiment with the potential of reducing costs (staffing and 24 hour chat service) while improving the user experience.
![Page 5: NCompass Live: Tech Talk with Michael Sauers: Artificial Intelligence: Transforming Reference](https://reader035.vdocuments.net/reader035/viewer/2022070315/555052e0b4c905c0448b4664/html5/thumbnails/5.jpg)
Why a chatbot? It is a conversational agent designed to simulate a conversation
with humans. It feels human and responds with a specific answer, not list of choices.
It is text based but it can include sound and visual effects. Undergrads are familiar with the software.
The software includes a database of answers that contains metadata, which is used to match against queries, which provides consistent answers.
It is available 24 hours a day 7 days a week. Ready whenever the patrons are.
All information from the website can be added to the database so patrons don’t have to hunt the website for answers.
People don’t worry their question is “stupid” or parents about the person on the other end.
The software can handle multiple questions at a time so there is no queuing.

RUSA guidelines for behavioral performance identifies five basic components of a reference interaction:1. Approachability- encourages patron to feel comfortable
Warm greeting and prominent position on website.
2. Interest- demonstrate a commitment to providing effective information assistance Answering in a timely manner and maintaining word contact.
3. Listening/inquiring-Listen effectively as the patron states in his/her own words the information need.Ask open ended and closed clarifying questions to understand the need, while keeping the patron at ease.
4. Searching- Identify the search strategy of the patron, conduct a search strategy, explain the steps and results to the patron, within the patron’s timeframe.Conduct and show your search strategy to the patron,
5. Follow-up- Determine if the patron is satisfiedAsk follow up questions. Invite patron to use the service, or other services again.

Approachability
Approachability- encourages patron to feel comfortableWarm greeting and prominent position on website.
HI I’m Pixel. What can I help you with?
That is okay, how can I help you?
Great, we have developed services to assist you with your distance coursework.
I Can look that up for you?
I can check encore for you?
Are you kidding?
Give me a minute to do a search of our articles.
Oh my, I am having trouble figuring this out.
No images either... I am stumped. Tell me again what you want.
![Page 11: NCompass Live: Tech Talk with Michael Sauers: Artificial Intelligence: Transforming Reference](https://reader035.vdocuments.net/reader035/viewer/2022070315/555052e0b4c905c0448b4664/html5/thumbnails/11.jpg)
Approachability
Responding to ‘difficult’ patrons. Encouraging patrons to be polite by answering politely.
Anger is a difficult emotion. For a machine, I always put others before myself.
Do you always express yourself that way?
Nothing is wrong with me. Is there anything wrong with you my friend?
Wow! OK I'll stop talking now.
Okay, you said "you to be quiet”
You seem pretty sure about that.
Some things are too emotional for me to discuss. Do you have feelings?

Showing Interest
Interest- demonstrate a commitment to providing effective information assistanceAnswering in a timely manner and maintaining word contact.
Yes, I have many journal articles. Why do you ask?
If this is your first research project, ask me about getting started.
Okay you do not want books You can find images in our Image and Multimedia Collections.
You should really give ”ENCORE” a try Come on. Just one little try ”ENCORE”
To speed things up, I can do a search for you if you say lookup followed by the subject, title or author.
Perhaps you should consult with a librarian.

There are three ways to ask any question
Corn* Corn
What do you have on growing corn
Corn *Corn information please
* Corn *Do you have any books on raising corn for the
paper I’m writing for school
![Page 24: NCompass Live: Tech Talk with Michael Sauers: Artificial Intelligence: Transforming Reference](https://reader035.vdocuments.net/reader035/viewer/2022070315/555052e0b4c905c0448b4664/html5/thumbnails/24.jpg)
So it gets more complicated two types of wildcards * and _ which act differently.
* is common wildcard match _ used with specific metadata
for example, “I _” would only retrieve a single category response

Subject and topic categories were derived from LC classification areas
There are two levels, topic broader (agriculture) subject narrower (corn)
The sole purpose of the two levels is to manage the conversation
![Page 26: NCompass Live: Tech Talk with Michael Sauers: Artificial Intelligence: Transforming Reference](https://reader035.vdocuments.net/reader035/viewer/2022070315/555052e0b4c905c0448b4664/html5/thumbnails/26.jpg)
Two levels keep the conversation going.
