use of akka.japi.Function in project webofneeds by researchstudio-sat.

the class SparqlMatcherActor method processActiveAtomEvent.

/**
 * Produces hints for the atom. The score is calculated as a function of scores
 * provided by the embedded sparql queries: the range of those scores is
 * projected on a range of 0-1. For inverse matches, the score is always 100%,
 * because there is only one possible match - the original atom. Note: this
 * could be improved by remembering reported match scores in the matcher and
 * using historic scores for normalization, but that's a lot more work.
