Hi,
I have a set of specific querie that my programme shoukd make to Wikidata.
How to best make such queries (information search) in terms of query
response time?
One approach that I am familar is to use APIs, such as Wikidata Toolkit API
<https://www.mediawiki.org/wiki/Wikidata_Toolkit>, to query documents in
Wiki and parse each document (and perhaps follow hyperlinks) for obtaining
the specific feature values. I have tested this, but the queries could take
seconds. Now there could be many factors responsible for this such as
internet connection, the scheme for parsing wikidata graph, etc.
Another approach would be to use the Wikidata Query Service
<https://query.wikidata.org/> and SPARQL queries. This is also slow
sometimes.
My questions:
- Are there benchmarks on response time performance of Wikidata Query
Service <https://query.wikidata.org/> SPARQL queries?
- Is there a JAVA API to the Wikidata Query Service
<https://query.wikidata.org/> interface?
- Can SPARQL be used to query a dump of Wikidata?
Thanks and regards
Raveesh
