如何获得每个功能的MAXEnt分类器NLTK权重

Question

maxent分类器具有8个功能，并且想知道每个权重，因为我需要有关每个功能有多重要的信息。

for i in range(len(list)):
        features = {}
        features['a'] = 0
        features['b'] = 0
        features['c'] = 0
        features['d'] = 0
        features['e'] = 0
        features['f'] = 0
        features['g'] = 0
        features['h'] = 0

        for j in range(len(list[i])):
            first, second = list[i][j].split('+')
            first_lexical, first_morph = first.split('/')
            second_lexical, second_morph = second.split('/')

            if first_lexical == second_lexical:
                features['a'] += 1
            if first_morph == second_morph:
                features['b'] += 1

                if "JC" in first_morph:
                    features['d'] += 1
                elif first_lexical == second_lexical:
                    if "EF" in first_morph or "EC" in first_morph or "ET" in first_morph:
                        features['d'] += 1
                    elif "EP" in first_morph:
                        features['e'] += 1
                    elif "XS" in first_morph:
                        features['f'] += 1
                    elif "JX" in first_morph:
                        features['g'] += 1
                    elif "JC" in first_morph:
                        features['h'] += 1

我使用最大熵是因为要计算两个句子之间的结构相似度。 所以我用特征作为相同语素的计数。这就是为什么要素值不为0或1的原因。

当我运行此代码时：

print(classifier.weights())

它打印列表的64个元素。 我认为它只显示8个元素（重量），但返回的结果如下：

我想知道每个元素的含义以及如何获得每个元素的权重。
