\spexkge: A Location-Aware Knowledge Graph Embedding Model for Geographic Question Answering and Spatial Semantic Lifting
Table 6: The evaluation of \spexkgessl and \spexkge′space on DBGeo for a few selected relation r (using APR (%) as evaluation metric).
['[EMPTY]', 'Query Type', '\\spexkge ′ [ITALIC] space', '\\spexkge  [ITALIC] ssl', 'ΔAPR']
Next, among all validation and testing triples with different relations, we select a few relations and report APR of two models on these triples with specific relations. These relations are selected since they are interesting from spatial reasoning perspective. We can see that \spexkgessl outperforms \spexkge′space on all these triple sets with different relations.
