Creative Data MiningMaking Most of Your Data to Improve Services

The Challenges• Budget cuts
• Staff reductions
• Increasing customer expectations for high quality library services
• Need a tool that can gather all the related deep “buried” data to perform systematical analysis and comparison, and supply meaningful data for decision-making. No such tool exists in current market.
![Page 3: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/3.jpg)
The Solution
• Nashville Public Library has been developing a deep data mining system, which can monitor almost all the aspects of its operation, and supply administration with decision-making data.
• This system has been playing significant role in easing the gap between
diminishing resources and demand for accountability.

Holds Management
“Holds Management” is a section of the whole system, we will use this section for today’s presentation
Note: The data use in this presentation is for demo purpose only, they do not necessary reflect the reality of the operation at Nashville Public Library
![Page 5: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/5.jpg)
What can the Holds Management do for us?
• Use our limited book budget to get maximum return in terms of meeting customer needs
• What titles should we buy
• How many copies should we buy and why
• What is the status of the related orders
• Automatically calculated based on mathematical formula

Collect All The Holds For Each Title
Challenge: Find out all the holds under each title and related items.
![Page 7: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/7.jpg)
Translate Holds Information To Purchase Decisions(1)
• Sample: The Broker/John Grisham - Holds 314
• Holds Ratio is 3:1
• The total number of copies to be added =
314 holds / 3 - the total number of copies purchased
![Page 8: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/8.jpg)
List out total number of items purchased under each title
![Page 9: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/9.jpg)
Translate Holds Information To Purchase Decisions(1) Continue …
• The total number of copies need to be added
= 314 holds / 3 - total copies purchased
= 314 holds / 3 – 55 copies
= 49.7 copies
Not all the copies purchased are still available for service
![Page 10: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/10.jpg)
Translate Holds Information To Purchase Decisions(2)
• We have to find out all the copies under each title that are no longer in service, which includes:
Lost & Paid
Damaged
Claim Returned
Withdrawn
Missing
Billed
Staff Use
![Page 11: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/11.jpg)
The system can identify all the “non-service” copies, deduct the amount from the total copies purchased, and arrive at the number of available copies accordingly:
![Page 12: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/12.jpg)
Translate Holds Information To Purchase Decisions(2) Continue …
• The total number of copies need to be purchased
= 314 holds / 3 - total number of available copies
= 314 holds / 3 – 36 copies
= 68.7 copies
What about the copies currently on order ?
![Page 13: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/13.jpg)
Translate Holds Information To Purchase Decisions(3)
• Finds out the total number of copies of each title currently on order
• Automatically links each title to its orders
![Page 14: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/14.jpg)
The system finds out all the items on order under each title and then list them out
![Page 15: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/15.jpg)
Translate Holds Information To Purchase Decisions(3) Continue …
• The total number of copies need to be added
= 314 holds / 3 - total number of available copies – total number of copies currently on order
= 314 holds / 3 – 36 – 32
= 36.7 copies
We should exam all the titles currently in cataloging process stage and include all the copies if there are any
![Page 16: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/16.jpg)
Translate Holds Information To Purchase Decisions(4)
• The system then searches the total number of copies of each title currently in processing at Cataloging Department
• If copies are found, they will be included in the calculation
![Page 17: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/17.jpg)
Locate the total number of copies under each title currently in processing
![Page 18: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/18.jpg)
Translate Holds Information To Purchase Decisions(4) Continue …
• The total number of copies need to be added
= 314 holds / 3 - total number of available copies – total number of copies currently on order – total number of copies currently in processing
= 314 holds / 3 – 36 – 32 – 2
= 34.7 copies
![Page 19: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/19.jpg)
Pay Attention to the Ratio Information !
There is a big difference in the ratios between book and DVD, why?
![Page 20: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/20.jpg)
Holds Ratio
• Books 3:1
• DVDs 12:1
Translate Holds Information To Purchase Decisions(5)

Translate Holds Information To Purchase Decisions(5) Continue …
Holds Ratio• Books 21 days check out + 3 times of 21 days renews = 21 days + 3 x 21 days = 21 days + 63 days = 84 days
• DVDs 7 days check out + 1 time of 7 days renew = 7 days + 7 days = 14 days
• 84 days / 14 days = 6 times
![Page 22: Project DirectorSuliang Feng Project Principal AssistantHongfei Li](https://reader036.vdocument.in/reader036/viewer/2022081603/568141c0550346895dad96c9/html5/thumbnails/22.jpg)
• If we use 3:1 as holds ratio for books then the holds ratio for DVDs should be (3 x 6) :1 = 18:1
• We use 12:1 as Holds ratio for DVDs for now
