LOD Search

LOD Search - Exploring the underlying ontology structure using the http://lod.openlinksw.com "Entity Search, Find, and Explore" service.

Example: To determine from LOD if a country has population property/predicate or not.

Option1: Using LOD Cloud Cache instance at: http://lod.openlinksw.com on the "Text Search" tab, in "Search Text Field"enter the pattern: "Australia Population" and select "Search".

The results screen displayed the following text at the top of the page.
"Displaying values and text summaries associated with pattern e1 where:
e1 has any property whose value contains "Australia Population"."

In the "Navigation" column of the results screen, select "Types".
The results screen now displays the following text at the top of the page.
"Displaying types of e1 where:
e1 has any property whose value contains "Australia Population". "

From the list of types under the "Type" column on the left hand side select those types best representing Australia
e.g.dbpedia-owl:Place and umbel-sc:Region

The results screen now displays the following text at the top of the page.
Displaying types of e1 where:
e1 has any property whose value contains "Australia Population".
e1 is a dbpedia-owl:Place . Drop
e1 is a umbel-sc:Region . Drop

In the "Navigation" column select "Property" to filter see the properties available.
There are properties from DBpedia and Geonames data spaces associated with the pattern.

The result should be similar to http://lod.openlinksw.com/fct/facet.vsp?cmd=load&fsq_id=3032.
This is based on the SPARQL query:

select ?s1p as ?c1 count (*) as ?c2 where { ?s1 ?s1textp ?o1 . ?o1 bif:contains '(AUSTRALIA AND POPULATION)' .?s1 a <http://dbpedia.org/ontology/Place> .?s1 a <http://umbel.org/umbel/sc/Region> . ?s1 ?s1p ?s1o . } group by ?s1p order by desc 2 limit 20 offset 20

Option2: Using LOD Cloud Cache instance at: http://lod.openlinksw.com on the "URI Lookup (by Label)" tab, type in: "population". The result is an auto-complete style list of all Classes, Prorperties, and Instance Data URIs that have pattern: "population", in their labels.
