Finding the right balance between
human effort and automation for
metadata creation

Expectations for discovery systems are
rising


Growth of cutting
-
edge systems outside of
libraries affecting user expectations


Higher user expectations is a good thing!


Many expected functions will be easier with
robust structured metadata


Genre access


Faceted browsing


Limiting scope by time, place, etc.

Libraries are having trouble meeting those
expectations


Non
-
textual resources are more difficult to
search


Legacy metadata isn’t always structured in
ways that allow high
-
level services


Legacy metadata doesn’t always include
enough information to allow high
-
level
services


Creating new metadata needed to provide
high
-
level services is prohibitively expensive

Enter automatic enhancement methods


Much research has been done


Little of it has been put into production systems in
library metadata creation environments


Still requires human intervention


Fear of human skills becoming devalued


Metadata aggregators, out of necessity, are among
the first implementers in the cultural heritage
community


Automatic enhancement holds great promise for
standardizing and streamlining metadata creation
and aggregation activities

IU’s interest in automated metadata
enhancement


IU DLP has a strong history of providing high
-
level
discovery services based on quality structured
metadata


Many collections could benefit


Legacy collections described in MARC


Special collections largely undescribed, especially at the
item level


Currently developing new digital library infrastructure
into which enhancement tools could be integrated


Technical services looking to expand metadata
activities

IU’s role in the DLF Aquifer Metadata
Remediation project


Preliminary data analysis


Define tools needed to review and report on
effectiveness of remediation experiments


Iteratively review results of the automatic
enhancement processes


Test human review workflows

Benefits to IU of the Aquifer Metadata
Remediation project


Better understand aggregated metadata


Identify remediation tools that address local
needs


Plan for inclusion of these tools into our local
workflows


Building relationships between the Digital
Library Program and Technical Services

The big picture from IU’s perspective


Automated metadata enhancement
techniques promise to play an essential role
in building and aggregating digital library
collections


But they are not a “magic bullet”


must be
used together with other techniques


User
-
contributed metadata


Content
-
based retrieval


Item
-
level attention by specialists
