Hi Rupert, Ok, I'll resend this mail in this thread. Again, out of habit I sent it in the gigantic "Named entities coreference" thread instead.
So, I managed to create a dbpedia index with the yago class information but looking into the yago_types.nt file which assigns yago classes to dbpedia entities I realized that there are no yago class labels present, I just have the class uri like : <http://dbpedia/..something../President1829302/. I also need the class labels so that I can compare them to the noun token's string from the text. I can get the labels from one of the yago downloads here : http://www.mpi-inf.mpg.de/yago-naga/yago/download/yago/yagoMultilingualClassLabels.txt. I'll need another yago download file to map the yago wordnet classes to dbpedia uris. That could be done via a script maybe. Once I have the dbpedia_yago_class_uri -> label file is it possible to integrate this data in the dbpedia index and later be able to query the labels from the 'dbpedia' Site? How would that work in the dbpedia indexing process? What should I change in the mappings.txt file? At first glance it seems that the indexing is done based on the incoming_links.txt entity scoring and in my case I don't want to include triples involving the actual entity but triples invloving a property of the entity (its yago class). Other than that, I saw that someone will be working on integrating YAGO as part of Gsoc 2014. So maybe waiting for that is an option too but I don't know what the extent of the integration will be.
