SPOTL • • • S: Subject P: Property O: Object T: Temporal L: Locate

SPOTL(X) representation • RDF models were queried using SPARQL queries. • They had a drawback that even a small query on a particular object required convoluted joins. • In order to over come this, a new model is presented. SPOTL(X) View: • Instead of seeing only SPO triples, now the user sees extended 5 -tuples where each fact includes its associated temporal and spatial information. • This is SPOTL view: SPO triples augmented by Time and Location.

Politicians who are also scientists, born nearby Hamburg, after the year 1900

Politicians who are also scientists, born nearby Hamburg, after the year 1900 • 위의 그림에서 표시해 둔 Hamburg를 쿼리상에 직접 near. By로 넣으면 결과는 아무것도 반환하지 않는다.

Companies founded in Silicon valley in the last 3 decades, together with their founders 앞의 문제와 같이 location에 silicon valley를 사용하면 아무것도 반환 하지 않아, keywords에 사용하여 유사한 결과를 얻어내었다.
