Table 4 The average runtime from 10 executions of the SPARQL query Examples 1-x, 2-x, 3-x, and 4-x, including one-time, twice, and three-times subqueries for the Query subparts 1 to 3, respectively
Query approach | Federated or Centralized | Target diseases | The runtime of 1 subquery (for whole of query subparts) [x = 1] | The runtime of 2 subqueries (for whole of query subparts) [x = 2] | The runtime of 3 subqueries (for whole of query subparts) [x = 3] |
|---|---|---|---|---|---|
Example 1-x | Federated | AD | > 600 s | > 600 s | > 600 s |
Example 2-x | Centralized | 307 s | > 600 s | > 600 s | |
Example 3-x | Federated | melanoma | > 600 s | > 600 s | > 600 s |
Example 4-x | Centralized | 502 s | > 600 s | > 600 s |
