Excerpt

We then focused on further optimisations not at the query-engine level, but at the dataset level, analysing it more deeply, and we identified that: (1) 188 distinct properties are used to link artists together directly; (2) 578 distinct properties are used to link an artist to any resource (including artists) ; (3) 767 distinct properties are used to link any resource (including artists) to an artist.

Synopsys

  1. optimize the dataset for the task >> optimize, Dataset, Task
  2. identify the distinct properties used to link artists directly >> identify, Distinct, Property, Link, Artist, Direct
  3. there are 578 distinct properties that link artists directly >> 578, Distinct, Property, Link, Direct
  4. identify the distinct properties used to link artists to any other resource >> identify, Distinct, Property, Link, Artist, Resource, AnyOther
  5. 767 distinct properties are used to link artists to any other resource >> 767, Distinct, Property, Link, Artist, AnyOther, Resource
