Hi there, I am a newbie to Jena and Fuseki. Currently I am trying to use Fuseki to load YAGO ttl file into database and want to make some SPARQL queries on the data set. Actually I first tried to use the official converter of YAGO to load all the ttl into Jena. The tool is on this page( http://resources.mpi-inf.mpg.de/yago-naga/yago/downloads_old.html). But the offical tool did not function well. And I have to use Jena directly. There are still some problem using Jena. When I loaded a small file like yagoSimpleTaxonomy.ttl which is 512KB, Fuseki works pretty well. I can make queries on the data. When I loaded a bigger size file like yagoSimpleTypes.ttl which is 300MB, Fuseki did not really work well. The log is like follows.
I will be really grateful for any replies. Thank you so much!
