What do users need?(the question that answers all the other questions)
Schaffner’s synthesis of user studies• Users search by subjects and keywords• Users expect results ranked by relevance• Users expect comprehensive coverage• Users know how to scan and scroll• Users lack awareness about collections
Schaffner, The Metadata is the Interface. http://www.oclc.org/programs/publications/reports/2009-06.pdf
Users search by subjects & keywordsLet’s buff up subject and keyword access!
Better Indexing• Appropriate hierarchies & subdivisions
match the granularity of user searches and browses
• User-supplied “tags”added value
show how users want to access and organize library resources;
data that libraries can use to inform better metadata and services
• Control (and publish!) local vocabularies• URIs
Things, not Strings
Abstracting• Support keyword access• Provide context• Let users know:
What it featuresWhat it isWhat it can be used for
Topic Modeling• Cluster related subjects together
ID collection strengths (“shop your closet”)
Let users surf related things
• Lets us get away with iffy dataDoes not require that every item in a subject area has the exact same heading
Users expect results ranked by relevanceLet’s support appropriate results!
Relevancy Ranking• Based on: where the search term appears
Subject headings TitleAbstracts Author-supplied keywordsFull text
• Based on: what it isCurrent publication Peer-reviewedType of material Length of material
… We can do better
Semantic SearchSemantic search technology relates user search queries to their probable intent, thereby offering more relevant results. This technology is built on a combination of understanding humans (e.g., natural language processing, concept matching) and understanding data (e.g., easily-parsed, uses URIs).
Understandable DataLinked Data = Data that machines understand
• BIBFRAME• Microformats
Schema.orgBib Extend
Users expect comprehensive coverageLet’s describe all the things!
Aggregate Description• Collection records in catalog• Finding aids• Landing pages• Subject guides
Greene & Meissner, More Product, Less Processhttp://www.uiowa.edu/~c024120/Readings/Greene-Meissner.pdf
Iterative Description• Content upgrades • Cooperative description• User-supplied content• Links to external resources• Ingest external data
Ascher, Progressing toward Bibliographyhttp://rbm.acrl.org/content/10/2/95.full.pdf
Users know how to scan and scrollLet’s support browsing!
Arrangement• Classification & call numbers• Shelflists• Series• Controlled access points
Subject & genre headingsCreators & other names
Uniform Resource Identifiers (URIs)Controlled access points … For the interwebs!
• Connect library collections
• Let users surf library resources alongside the Web
Guided SearchOrientation, Inspiration & Interpretation• Subject guides• Saved searches • Bibliographies • Pathfinders• Visualization
Visualization
Users lack awareness about collectionsLet’s put collections in their face;Let’s get the metadata out there!
Put Your Metadata Other Places
Let Folks Access Your Metadata• OAI-PMH & OAIster• APIs• SPARQL endpoints• Data dumps• Export options
• Linked Data: expose data to the Web• URIs: create links between library metadata & other resources
Create Shareable Metadata• Content is optimized for sharing• Metadata … reflects consistent practices• Metadata is coherent• Context is provided• The metadata provider communicates with aggregators • Metadata and sharing mechanisms conform to standards
Shreeves, Riley, and Milewicz, Moving Towards Shareable Metadata.http://firstmonday.org/ojs/index.php/fm/article/view/1386/1304
More ConsiderationsInternationalization• Use clear, concise language
• Cultural relevance
• Character encoding
Policy• Explicit CC license
• Own the data you share
