TEST_F(HistogramUtilsTest, CommonPrefixLength) {
  EXPECT_EQ(common_prefix_length("", ""), 0ul);
  EXPECT_EQ(common_prefix_length("a", ""), 0ul);
  EXPECT_EQ(common_prefix_length("a", "b"), 0ul);
  EXPECT_EQ(common_prefix_length("aa", "a"), 1ul);

}

Beispiel #2

Datei: field_comparator.c Projekt: michelboaventura/cpareia

double
winkler(char *s, char *t, int ss, int st) {
  float dist, pref_length;

  if (!strcmp(s, t))
    return 1.0;

  dist = jaro(s, t, ss, st);
  pref_length = common_prefix_length(4, s, t, ss, st);
  dist = dist + pref_length * 0.1 * (1 - dist);

  return dist;
