Sar-graphs: A Linked Linguistic Knowledge Resource Connecting Facts with Language
5 Fourth Workshop on Linked Data in Linguistics: Resources and Applications (LDL-2015) at ACL-IJCNLP 2015, Beijing, China, ACL, 2015
 
We present sar-graphs, a knowledge resource that links semantic relations from factual knowledge graphs to the linguistic patterns with which a language can express instances of these relations. Sar-graphs expand upon existing lexico- semantic resources by modeling syntactic and semantic information at the level of relations, and are hence useful for tasks such as knowledge base population and relation extraction. We present a language-independent method to automatically construct sar-graph instances that is based on distantly supervised relation extraction. We link sar-graphs at the lexical level to BabelNet, WordNet and UBY, and present our ongoing work on pattern- and relation-level linking to FrameNet. An initial dataset of English sar-graphs for 25 relations is made publicly available, together with a Java-based API.
