5. MARC
• MARC Format Record
- has been a cataloging tool in the library
community since the 1960’s
- has more than 1,900 fields
- has made libraries move towards the
Computer Age (Tennant, 2004)

6. Changes - Environments
• Libraries have lost their place as primary
information providers (Coyle & Hillmann, 2007)
• Users’ search behaviors have changed
• Printed book is no longer the only major
vehicle for scholarly communication (Sandler,
2005)
• Increase in diverse formats/web-based
information resources

7. Changes - Metadata
• Metadata
- contains more than descriptive information
- is harvested and converted
- is provided by vendors and others
- is enhanced by users
- should support discovery service

• Creating/extending metadata schemas
–*Assess the granularity of access points
–*Develop a new set of elements
(Application profile)
–Identify available semantics
–Create a new metadata schema

32. Is Granularity the Next
Discovery Frontier?
Granular Discovery: User
Challenges and Opportunities
Tito Sierra
Director of Product Management, Search
EBSCO Information Services
33. EBSCO Discovery Service
Agenda
• The Evolution of Library Discovery
• Discovery in the Age of Google
• Metadata and Granular Discovery
– Metadata-centered approaches
– User-centered approaches
• Concluding Thoughts
35. EBSCO Discovery Service
The Evolution of Library Discovery
Library search has come a long way
• OPACs
• Online Research Databases
• Federated Search
• Next Generation Catalogs
• Web-scale Discovery Services
36. EBSCO Discovery Service
The Evolution of Library Discovery
From siloed discovery to unified discovery
• Articles / e-journal content
• Print collection (catalog)
• E-books
• Magazines / trade publications / news sources
• General reference / specialized reference
• Multimedia (images, audio, videos)
37. EBSCO Discovery Service
The Evolution of Library Discovery
Supporting a variety of discovery needs
• Known-item book and article citation search
• Exploratory search / topic exploration
• Discipline-specific research / literature reviews
• Curriculum support / course assignments
• General reference / specialized reference
• Specialized content discovery
40. EBSCO Discovery Service
User Expectations for Search
Shaped by popular search engines
• Support basic keyword search
• Deep content coverage
– Diverse content types
– Diverse content sources
• Predictive relevance ranking
• Intelligent search features
– Autocomplete, Did-you-mean
41. EBSCO Discovery Service
Findings from EDS User Research
Observation Implication
Keyword search most
common
Discovery service cannot assume users will pre-
coordinate their search. Discovery service needs to
anticipate user intent based on limited input.
Faceted search used
sparingly
Discovery service cannot assume users will post-
coordinate their search. Discovery service needs to
provide more user-friendly narrowing options.
Search queries length
often short (1-2 words)
Discovery service needs to anticipate user intent
based on limited input. Search features needed to
help users clarity their search intent.
Broad and imprecise
queries common
Discovery service needs to help users narrow their
search based on limited input. Many users looking for
a topical overview on a subject.
User focus on top
results
Relevance ranking crucial for delivering a quality
search experience. Need to optimize search to display
most relevant results on first page.
42. EBSCO Discovery Service
The Discovery Service Challenge
Despite major evolutions in library search,
libraries, publishers, and discovery service
providers need to work harder to meet
evolving user expectations for search.
43. EBSCO Discovery Service
The Discovery Service Advantage
One advantage that library discovery
services have over general purpose
search engines is access to high-quality,
well structured metadata.
55. EBSCO Discovery Service
Metadata-centered Approaches
Advanced Search and Faceted Search are
powerful tools—for those who know how
to effectively use them.
They require user to translate discovery
need into the language of metadata.
Consequently they are underutilized.
57. EBSCO Discovery Service
User-centered Approaches
Anticipate end user intent using clues from
the user query and user context.
Deliver targeted content at the top of the
results list where users expect.
61. EBSCO Discovery Service
Metadata Necessary But Insufficient
Supporting access to increasingly granular
chunks of content will requires capture and
management of finer-grained metadata.
Metadata needs to be coupled with search
intelligence to have a broad impact.
62. EBSCO Discovery Service
Areas for Future Investment
• Deepen analysis of usage data to better
understand user context and expressed
granular discovery needs
• Develop intelligent bridging between user
queries and granular metadata
• Build in adaptive learning capabilities to
automatically refine intelligent search
approaches over time
