A survey of RDF storage approaches

David C. Faye, Olivier Curé, Guillaume Blin
2012 ARIMA  
There is a real need to efficiently store and retrieve RDF data as the number and scale of Semantic Web in real-word applications in use increase.  ...  Efficient data storage and query processing that can scale to large amounts of possibly schema-less data has become an important research topic.  ...  To speed up keyword queries, the lexicon keeps an inverted index on string literals to allow fast full-text searches.  ...
