What are some papers dealing with Semantic Data in YAGO ?
SELECT DISTINCT paperkeyphrase.paperid FROM dataset, keyphrase, paperdataset, paperkeyphrase WHERE dataset.datasetname = 'YAGO' AND keyphrase.keyphrasename = 'Semantic Data' AND paperdataset.datasetid = dataset.datasetid AND paperkeyphrase.keyphraseid = keyphrase.keyphraseid AND paperkeyphrase.paperid = paperdataset.paperid
SELECT DISTINCT "paperkeyphrase"."paperid" FROM "dataset" JOIN "paperdataset" ON "dataset"."datasetid" = "paperdataset"."datasetid" JOIN "paperkeyphrase" ON "paperdataset"."paperid" = "paperkeyphrase"."paperid" JOIN "keyphrase" ON "keyphrase"."keyphraseid" = "paperkeyphrase"."keyphraseid" AND "keyphrase"."keyphrasename" = 'Semantic Data' WHERE "dataset"."datasetname" = 'YAGO'
