Class AutoSimilarityHandler

java.lang.Object
  org.jactr.core.utils.similarity.AutoSimilarityHandler

All Implemented Interfaces:

SimilarityHandler

public class AutoSimilarityHandler
extends java.lang.Object
implements SimilarityHandler

AutoSimilarityHandler that computes the similarity between any two chunks based on average of the similarities between their slot values. This is similar, if not identical to Raluca's proposal. 0. if they are the same, return maxsim 1. if the sim between two chunks is already defined, return it 2. if they are of the same chunk type, or derivable chunk types - compare the slot values based on the smaller of the two chunks 3. if they are not related chunk types - return maxDiff 4. if they are both numbers - return the diff scaled by maxDiff/maxSim 5. if they are strings.. well, screw them
