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
