Hi all,
I have doubts about some dbpedia pages.
The page
"http://dbpedia.org/page/List_of_Star_Trek:_Enterprise_episodes";
collects a list of star trek episodes. For each episode is available
in the page the title, a short summary, the writer, etc. . All titles
are values of the property "http://dbpedia.org/property/title";, and
all short summaries are values of the property
"http://dbpedia.org/property/shortsummary";. Now can I connect each
title to the right short summary? Is this possible? Should I relay on
the order in which the information appear in the nt files?
Tania,
That's the only option you have, but it will be a matter of luck if it
works correctly. Each assertion is independent of all the others, and
order is not significant. In an ideal world, the page would be a list
of episodes, each of which would have its own page.
The simple extraction strategy used to generate dbpedia "pages" from
Wikipedia ones doesn't allow for co-contextual relationships between
pairs or groups of assertions within the page. It would be nice if it
could. Another simple example of this is the Berlin page, which has:
dbpedia-owl:populationAsOf <http://dbpedia.org/ontology/populationAsOf>
* 2009-09-30(xsd:date)
dbpedia-owl:populationMetro <http://dbpedia.org/ontology/populationMetro>
* 5000000(xsd:integer)
dbpedia-owl:populationTotal <http://dbpedia.org/ontology/populationTotal>
* 3439100(xsd:integer)
If these were grouped into a "populationOnDate" entity, it would be
possible to record changes in the population of Berlin over time. As it
is, you only get one shot at it (and you have to make your own
connection between these independent assertions).
