27. Going from Tables to Graphs
As computing power increases, the ability to build
more and more complex graphs becomes a reality.

28. Introducing Triples
Nodes and Links
follows
jonvoss 1n9r1d
• Quite simply: Subject, Predicate, Object
• gives us the ability to describe entities in a way
that is machine readable
29. What do we know about the person:
Ed Summers (aside from the fact that he rocks)?
Bio: Hacker for
libraries, digital

30. Triples for machines
• Triples can be serialized in many different ways,
including Resource Description Framework,
RDF/XML, RDFa, N3, Turtle, etc, but they all
describe things in the
<subject><predicate><object> format.
• Of course, we need to be consistent and
predictable for machines to understand us.
• We need to follow simple rules and protocols
33. • Consider graph demo: http://civilwardata150.net
• Civil War vocabulary, or a way to link and traverse across datasets
• Regiments, Battles, Places
• Building apps that use this data

70. The World of Linked Data
The Linked Data
cloud as a whole
grew by 300% in
2010...
...whereas the
amount of data
relevant for libraries
grew by nearly
1000%

103. Linked Data.
• Goal is to enable researchers to explore and interpret the commonalities or
divergences in the data.
• Multiple significant scholarly humanities datasets to pipe in and aggregate
with varying levels of standards and technologies.
• Information design challenge to build an ontology and use linked data and
controlled vocabularies for data to be aligned and related.
• Provide a virtual environment to explore this data and process with tools.

105. Rethinking Resource Discovery.
• Goal is to enable researchers to explore and interpret the commonalities or
divergences in the data.
• Support researcher needs to discern facts (what is?) and locate more
information (where is?) drawing on Australian cultural scholarly data.
• Major task is to aggregate heterogeneous humanities data that may be
related to digital representations e.g. digital text, audio-visual etc files.
• Method is linked data, using ontology and controlled vocabulary
development.
• Outcomes are the researcher can move easily from: what is? to where
is? in their information seeking.
106. Information Seeking.
• Information seeking is supported by intellectual access tools, which include
library catalogues, archival finding aids, reference tools, subject databases,
journal repositories and information resources (physical and digital).
• Critical step in information seeking is undertaken in preliminary visit to the
“reference shelf” and it can often be revisited to satisfy research questions.
• What is the researcher question? What information can I find out about this
person and their life, what they have done, etc. A classic biographical
enquiry.
• Know the name and other facts associated with a person in the HuNI graph
(in the lab) and follow a hyperlink to a range of web resources related to that
person.
107. Metadata Mash Up.
• A mash up of reference tools and finding aids: factbooks, dictionaries,
encyclopaedias, bibliographies and catalogues and archival registers.
• Link needs to be forged with the ontologies for domain resources e.g. TEI and
resource discovery metadata.
• Exploring this with the crosswalk between CIDOC-CRM and FRBR-OO (latest
draft) and keeping an eye on BibFrame.
• Same problem being explored in another NeCTAR virtual lab project: Human
and Communication Science.
• Role of annotation and metadata in discovery of new knowledge or the
means to elucidate new knowledge needs to be unpacked.
112. Ontology Development.
• Information design challenge to build an ontology and use linked data and
controlled vocabularies for data to be aligned and related.
• Reading the data. Characteristics of the data determine the ontological
components selected and the major “entities” (aka “access points” in
library lingo).
• Identified early as: people, organisations, events, relationships, places,
dates, resources, and subjects.
• Components from ontologies already available are being reused or kept in
our sights: CIDOC-CRM, FOAF, SKOS, FRBR, FRBR-OO, BibFrame and
PROV-O.
