我正在使用WS4j来查找两个单词之间的相似性。我也在使用Wu-Palmer相关性计算器。它适用于许多单词,但是当我试图找到“播放”之间的相似性时。并且' play',它给出得分1.3333,这是不可能的,因为它必须在0和1或-1之间返回。我无法弄清楚原因。 当我使用其网络界面' http://ws4jdemo.appspot.com/?mode=w&s1=&w1=play&s2=&w2=playing'它返回0.875。 这是我的代码:

 private static void findSimilarity(String word1, String word2) {
    WS4JConfiguration.getInstance().setMFS(true);
    List<POS[]> posPairs = wup.getPOSPairs();
    double maxScore = -1D;

    for(POS[] posPair: posPairs) {
        List<Concept> synsets1 = 
          (List<Concept>)db.getAllConcepts(word1, posPair[0].toString());

        List<Concept> synsets2 = 
          (List<Concept>)db.getAllConcepts(word2, posPair[1].toString());

        for(Concept synset1: synsets1) {
            for (Concept synset2: synsets2) {
                Relatedness relatedness = wup.calcRelatednessOfSynset(synset1, synset2);
                double score = relatedness.getScore();

                if (score > maxScore) { 
                    maxScore = score;
                }
            }
        }
    }

    if (maxScore == -1D) {
        maxScore = 0.0;
    }

    System.out.println("sim('" + word1 + "', '" + word2 + "') =  " + maxScore);
}
