1.5 HKUL DL initiatives
1.5 HKUL DL initiatives
Imaging database
1.5 HKUL DL initiatives
• 1.5.1. Digitalization projects
e.g. ExamBase
–
–
–
–
–
–
First in-house developed database
Imaging database for past exam. papers
Released in 1996
Use DMS, client-server model
Shifted to web-based soon
tiff only (on-the-fly convert to gif/jpg) , no PDF!!!
1. Hardware

High-speed flat bed scanner (36ppm)
2. Software
Kofax capture 3.0


Sophisticated software includes scanning, OCR,
verifications.
3. Logistics
a.
b.
c.
d.
Scanning
Automatic indexing
Verification and manual inputting
Data Publishing
Publish data to Oracle database
a. Scanning


Papers are scanned in batch mode (~200 pages per
batch)
Uses separation sheet to separate different
documents
(The separation sheet is printed with barcoded index
(e.g. department, course code) and fixed-sized font
text The separation sheets can be re-used.)
b. Automatic indexing

To recognize those barcoded indexes and text
printed on the separation sheet
c. Verification and manual inputting



No need to verify the barcoded indexes, as
the accuracy is > 99.999%
In-doubt OCRed text is marked in red, it is
easy to verify
Input other indexes manually (e.g. exam.
date)
1.5 HKUL DL initiatives (cont.)
• e.g. Newspaper clippings
– Full-text imaging database
– Outsource: scanning/indexing/OCR
– Oracle context cartridge as full-text search
engine (supports no Chinese!)
– Decision: keep on using? or buying a 3-rd
party full-text software??
1.5 HKUL DL initiatives (cont.)
• 1.5.2 Value-added Bibliographic databases
– Subset of library catalogue
– e.g. TOC , Thesis Online, AV materials..
– Debate:
• single point source or a number of subsets??
1.5 HKUL DL initiatives (cont.)
e.g. Table of Contents
• To automate the inputting of TOC into
bibliographic records
1. Hardware

Overhead book scanner (~4sec per image)
2. Software
Kofax capture 3.0


Sophisticated software includes scanning, OCR,
verifications.
3. Techniques
a.

d.
Scanning
Chinese OCR
Proofreading
Data Publishing
Publish data to Catalogue
a. Scanning
Use book scanner to scan the book’s TOC
benefits :






no need to flip the book for scanning
can scan two sides at one time
increase the speed of scanning
b. Chinese OCR
A plug-in module was written to interface with
Kofax Capture for Chinese OCR (TH-OCR 7.5)
c.


Proofreading
Use MS Word (Chinese) to do the proofreading
Macro program was written to ease the step of
assigning MARC sub-fields
d. Publish data to Catalogue


Done at night in batch mode
Use tcl/tk expect script to automate the upload
process
1.5 HKUL DL initiatives (cont.)
• 1.5.3 Subject-based e-resources
–
–
–
–
–
Redesign tag 996
A number of useful information on e-resources
Grouping of materials by subject: fulfill users’ needs
Ease of extending our further DL projects (e.g. portal)
See HKUL HP (databases, EJ, Ebooks & ENews)
• 1.5.4 Internet resources
• 1.5.5 Electronic Delivery (ILLiad)
1.5 HKUL DL initiatives (cont.)
• 1.5.6 Virtual services
– E-forms (e.g. BRO)
– Online reference
• 1.5.7 Automation
–
–
–
–
–
Increase efficiency
e.g. amend thousand of records in batch
Electronic submission
Staff intranet
Innoface
1.5 HKUL DL initiatives (cont.)
• 1.5.8 Collaboration
– Union catalogue w/ Jinan University
• 1.5.9 Authentication : Proxy, ezproxy, IP
control

Storage Area Network (SAN)
Abundance of servers
One-stop search
Alert service
Wireless applications
2.1 SAN
Problem a: Storage
large data size of our hosted databases
high monthly data increase rate
Databases are hosted in different
hosts/OS
2.1 SAN (cont.)
Problem b: Backup
backup drive for every machine
backup software license for every machine
Need to handle a lot of backup tapes
2.1 SAN (cont.)
Solution – (SAN)
Put all data storage into a single large-sized
expandable storage device.
The storage device is connected to the hosts by
high-speed Fiber channels
Fiber channel loop is used to connect to each
host in order to ensure high availability
Backup can be done on a single device
2.2 Abundance of servers
Problem :
Hard to monitor the status and activities
of each server
Waste time to tune the performance of
each server
2.2 Abundance of servers (cont.)
Solution – Server consolidation
Buy several powerful servers instead of many
cheap mid-range servers
Keep as minimal servers as possible
Save space and UPS power ratings , i.e. $$
saving
Save man power to administer/maintain server
performance , i.e. cost saving
2.3 One-stop search
 Before searching, one needs to know
which database suit one’s need
 To search multiple databases
simultaneously
 e.g. OAI (http://www.openarchives.org/ )
 e.g. CDL SearchLight
(http://www.cdlib.org/cgi-bin/searchlight)
2.4 Alert service
To alert users for new information
SDI
2.5 Wireless Application
A study on mobile and PDA application in
Library
