Text field candidate evaluation works like classification evaluation.

For example, you have a given text field, a given document, and Brainware extraction as an evaluation method that returns weights for each candidate.

Candidate evaluation uses two values defined at the field level to decide whether there is a valid candidate.

  • A minimum weight called threshold (by default 50 percent)
  • A minimum difference in weight between the best candidate and the second-best competitor called distance (by default 10 percent.)

Both requirements must be true to extract a valid candidate.

Example

  Weight of Candidate A Weight of Candidate B Weight of Candidate C
Field A 0.45 0.36 0.28
Field B 0.30 1.00 0.00
Field C 0.55 0.49 n/a

Result

  • For field A, there is no valid candidate. The weight of candidate A is below the threshold, and the distance to candidate B is below the minimum distance.
  • For field B, candidate B is a valid candidate. Its weight is above the threshold. In addition, the distance to the second-best competitor, Candidate A is above the minimum distance.
  • For field C, there is no valid candidate. The weight of candidate A is above the threshold, but the distance to candidate B is below the minimum distance.
