Hi Philipp,

We have unzipped the Wikidata dump and gotten two files: wikidata2018_09_11.hdt.index.v1-1 and wikidata2018_09_11.hdt.
But we cannot read the content with different text editors. How do you read them? Thank you for your help.

Hi Sirui,

HDT has an efficient representation of the KB, and the stored data is not meant to be directly readable (see https://www.rdfhdt.org).
In case you do not want to mess around with huge knowledge bases, and just want to conveniently access relevant facts for a specific entity or question, I can recommend also taking a look at our latest project CLOCQ which will be published as full paper at WSDM2022, for which we will soon have an open API available: https://clocq.mpi-inf.mpg.de.

If you want to look at the plain Wikidata KB-dump, you can download the latest dump (https://dumps.wikimedia.org/wikidatawiki/entities/). We also have a code-base for extracting a QA-related subset from Wikidata (https://github.com/PhilippChr/wikidata-core-for-QA).

Hi Philipp,

Thanks for the reply. As for the Wikidata dump that you sent through email (wikidata2018_09_11.hdt.index.v1-1 and wikidata2018_09_11.hdt), is it already extracted to a QA-related subset?

Hi Sirui,

No, this is the full Wikidata dump from that timestamp.

Hi Philipp,

Thanks a lot. Could you please explain how to construct the context graph for turn 0? For example, given the question "When did The Carpenters sign with A&M Records?", seed entity "The Carpenters" and the answer "1969", I can identify the answer triple is

http://www.wikidata.org/entity/Q223495
http://www.wikidata.org/prop/direct/P571
"1969-01-01T00:00:00Z"^^<http://www.w3.org/2001/XMLSchema#dateTime>

Does the context graph only contain this triple or also contain triples (The Carpenters, ?, A&M Records)? According to your methodology, my understanding is that the context graph contains only one triple; however, according to Figure 1, my understanding is that the context graph also contains triples (The Carpenters, ?, A&M Records).

Sincerely appreciate your help.

Hi Sirui,

The qualifiers are missing in this case.
The fact "Carpenters, record label, A&M records" is there in Wikidata
(https://www.wikidata.org/wiki/Q223495),
but misses the qualifier "point in time, 1969".

In Figure 1, these qualifiers are there.
