Current Trends,Tools & Techniques,

and the Role of Vendors

Harper - ELUNA - LODLAM Trends, Tools, Vendors - May 1, 2014

The Web Becomes Semantic

●Originally:● Metadata about “Web” things (documents)

●Eventually:● Metadata about all sorts of things● And about relationships between things

●TBL’s original vision (Weaving the Web – 1999)●Then: Focus on Machine Reasoning

● Scientific American Article●Now: Focus on things & links

● Reasoning & Inferencing less central


Linked Open Data

●Use URIs as names for things ●Use HTTP URIs so that people can look up those names. ●When someone looks up a URI, provide useful information. ●Include links to other URIs, so that they can discover more things. http://www.w3.org/DesignIssues/LinkedData.html

W3C Library Linked Data Incubator Group

Recommendation 4.3.1: Design and test user services based on Linked Data capabilities

“Experimental services using library Linked Data should be undertaken in order to explore potential use cases and inform the direction of larger development efforts.”


Linking Lives

“utilising external datasets in order to bring archives together with other data sources”

“there is still a need to make a convincing argument that Linked Data really will provide concrete benefits to the end user.”

Annotations

●The Pundit (thepund.it)●Hypothesis: Peer Review for the Web (hypthos.is)●Open Annotation Collaboration●Distributed bibliographic control environment

● Focus on identification over description

“In short, by treating values as non-literal resources and assigning URIs to them we give ourselves (and others) the hooks on which to hang further descriptions.” - Andy Powell


ContextNarrative

Story telling

The Library's story,and the Archives story,

but also…


Users’ storiesScholars' stories

Adding context through recombinant metadata

Scholar's Stories - LAWDI

●Linked Ancient World Metadata Institute (now Initiative)● Archaeologists, Numismatists, Classicists● Quasi- Digital Humanities

●Doing their own Linked Data● Pleiades: Ancient Place Names data

●Excited about Libraries helping● VIAF, id.loc, FAST, OCLC #’s etc…

Library Authority Data

“Include links to other URIs. so that they can discover more things.”

Short of providing and linking to URIs, this *is* authority data.

This is what our authority files are for.


Linked data is about context

authorities provide context

and yet our controlled vocabsare nearly gone

because the interfaces to them were broken


The Death of Browse

• Next-Gen Discovery Systems don't make use of Authority Control

• “Browse” was/is broken as a UI Design

• Rich data in Authorities, disconnected from narrative, context, search

• Richer “Authority” type data outside libraries...


Tools - Natural Language Processing

Where does this lead?

We need new interfacesnew tools

for new kind of catalogersfor knowledge organization experts

Open Refine RDF Skeleton


A bit louder...

we need new interfaceswe need enterprise tools

Integrated into our metadata management systems

for new kind of catalogersfor knowledge organization experts

It all started in 2011


ELUNA / IGeLU LOD SIWG

Manifesto:http://igelu.org/special-interests/lod/manifestoObjectives:● Essential linked open data features in all Ex Libris

products where appropriate

Means:● Collect use cases, scenarios from customers● Discuss and collaborate with Ex Libris

Meetings: All afternoon today!

http://igelu.org/special-interests/lod/manifesto


Collect and Present Use Cases

• Building on Manifesto and on Vision, Use Case & Requirements Document

• Template based on W3C LLD XG• Background, Current Practice, Scenario,

Goal, Audience, Limitations, Etc.• Listserv Discussion• Monthly(-ish) WebEx hosted by Ex Libris

**

And onward...

• Rethinking LAM UI Design• Aggregate data from more sources• Provide more context

• More proofs of concept• Provide tools and workflows for:

• Named Entity Recognition • Natural Language Processing• Metadata Aggregation / Provenance Management

• Bibframe & Schema.org• More use cases• Join the Discussion:
