2. Irish Record Linkage, 1864-1913
• Developing a platform applying semantic
technologies to historical birth-, death andtechnologies to historical birth-, death and
marriage certificates.
• Answering questions such as: “How accurate are
historic maternal mortality rates (MMR) and
infant mortality rates (IMR) for Dublin?”
• Team consists of researchers (historians), digital
archivists, and knowledge engineers.

3. Data: General Office Records
• Vital registration data
– Birth-certificates– Birth-certificates
– Death-certificates
– Marriage records
• Digitised TIFF images of
hardcopy indexes and
registers.
• 2 TB of data• 2 TB of data
• Database describing the
digitised records allowing
searches on some fields.

4. Challenges
• Certified causes of death that can be attributed to maternal
death
– Within 42 days after labour – before (1864) it was 12– Within 42 days after labour – before (1864) it was 12
– Septicemia (blood poisoning), Fever, …
– “Corresponding” birth certificate?
• Death certificates with no corresponding birth certificate
• “Gaps” in sibship interval, even though no birth- or death
certificates can be found.
• The terminology used pre-1900. E.g., “debile” to denote• The terminology used pre-1900. E.g., “debile” to denote
weak or a failure to thrive.
• Capturing the socio-economical status of the families via,
for instance, the professions, ranks of fathers.

protection is key.

7. Development of 2 ontologies
• 2 ontologies were developed – separation of concerns
• First ontology for describing the contents of records
– OWL 2 shallow, “flat ontology”
• Second ontology for data analysis
– OWL 2 + rules
– Rules to capture background and domain knowledge– Rules to capture background and domain knowledge
– Developed by having the historians formulate competency
questions (Grüninger and Fox)
– Captured graphically using Object Role Modelling

10. Conclusions
• Presented the problem and highlighted the
challengeschallenges
• Developed two ontologies
– Encoding contents of digitized GRO records for
long-term digital preservation DRI
– Data analytics to answer the researchers’
question – in this case a historianquestion – in this case a historian
• Data exploration and annotation of the
records started on a subset of the dataset
