Hi Denny,<div><br></div><div>Thanks. We extracted the mapping relations using several algorithms for a high precison, however, we need to check quality of this datasets. We are now investigating how to integrate both Freebase and Wikidata datasets using a single schema. The mappings can be useful for that job. However, a coverage of the mappings is still very limited. Is there any plasn for merging both datasets?</div><div>I will update the git with descriptions.</div><div><br></div><div>Best,</div><div>Haklae</div><div><br>On Friday, April 10, 2015, Denny Vrandečić &lt;<a href="mailto:vrandecic@google.com">vrandecic@google.com</a>&gt; wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Wow, Haklae, great work, thanks!<div><br></div><div>I took the mappings that your team has provided, and was able to increase the number of mapped triples by more than a factor of two, i.e. in the relevant step I have an increase from 8.5M mapped claims to 20.7M mapped statements.
