Lewis Topographical Dictionary of Ireland on the Semantic web.

Today we’ve successfully launched Phase 1 of the conversion of the
Lewis Topographical Dictionary of Ireland (1842) to the Linked Open
Data web. Publishing location, related entries and natural resource
entities extracted
from over 3000 entries in the Dictionary, this represents the first
stage in what will be a complete edition in RDF form, linked to dbPedia,
GeoNames, and many other semantic data sets on the Linked Web.

Using a custom entity extraction and RDF generation framework to
analyse concepts and meaning within the text of each entry in the
dictionary, we publish semantic web triples of information for

  • location,
    • administrative region,
    • type,
    • population,
    • direction to and from
    • bearing
    • geonames equivalent
    • dbpedia equivalent
  • natural resource,
  • related entries.
  • Members of Parliament (Dec 4)
  • original text

Linking with GeoNames and dbPedia adds the Lewis Topographical
Dictionary as a node on the Linked Open Data web and provides the basis
for more relevant search, inferral and exploration of the rich content
offered in this body of work to historians, archivists, genealogists,
geographers and those in heritgage and the environment.

Later phases of the project will cover the extraction,
contextualisation and linking of people, arts and architecture,
ecclesiastical and other institutional bodies mentioned in the

The first phase typically represents information in the following way
(this is the entry for Achonry)

While an ontology for this isnt yet available yet, it easy to
see the structure and elements that are contained. A formal ontology is
being constructed.

endpoint is available.

Unless you’re a machine , its highly recommended that you use Tabulator in Firefox to view the information in the corpus. Some sample direct locations here show particular entries

Some queries across the data set

As of Dec 4

We’ve been using

to build this, with brute force regexp, gazeteers and some cold coding.
We also looked at lots of other frameworks and machine learning
development environments (GATE, UIMA, OpenNLP, Minorthird, LingPipe), and I
have no doubt we’ll come back to them in time.

The extraction is not perfect of course (as you can see above in
dc:related and lew:toPlace), but it gets better each time we run it.
Tabulator doesnt seem to be able to deal well with embedded hash links
– but perhaps thats just me on a Friday night. Next steps involve extracting people, arts
and architecture, and getting the ontology completed so we can add in
