Examples with GND org.elasticsearch.search.aggregations.bucket.significant.heuristics.GND used on opensource projects

Example 6 with GND

use of org.elasticsearch.search.aggregations.bucket.significant.heuristics.GND in project elasticsearch by elastic.

the class SignificanceHeuristicTests method testGNDCornerCases.

public void testGNDCornerCases() throws Exception {
    GND gnd = new GND(true);
    //term is only in the subset, not at all in the other set but that is because the other set is empty.
    // this should actually not happen because only terms that are in the subset are considered now,
    // however, in this case the score should be 0 because a term that does not exist cannot be relevant...
    assertThat(gnd.getScore(0, randomIntBetween(1, 2), 0, randomIntBetween(2, 3)), equalTo(0.0));
    // the terms do not co-occur at all - should be 0
    assertThat(gnd.getScore(0, randomIntBetween(1, 2), randomIntBetween(2, 3), randomIntBetween(5, 6)), equalTo(0.0));
    // comparison between two terms that do not exist - probably not relevant
    assertThat(gnd.getScore(0, 0, 0, randomIntBetween(1, 2)), equalTo(0.0));
    // terms co-occur perfectly - should be 1
    assertThat(gnd.getScore(1, 1, 1, 1), equalTo(1.0));
    gnd = new GND(false);
    assertThat(gnd.getScore(0, 0, 0, 0), equalTo(0.0));
