Question

我正在尝试使用python在Synsets中找到 WordNet (which is Lexical database for English) 。

这是我尝试查找同义词集的代码以及该同义词集的示例（作为参数传递）：

 from nltk.corpus import wordnet
synonynm=wordnet.synsets('friend')[2]#? wt does[0] mean
synonynm.name() #related synonyms wrds
synonynm.definition() #definition of passed words
wordnet.synsets('friend')[0].examples()

当我使用索引 wordnet.synsets('friend')[0] 或 wordnet.synsets('friend')[1] 或 wordnet.synsets('friend')[2]

它给了我相同的输出，可以在这里查看

['he was my best friend at the university']

但是如果确实将花括号放空，则会显示错误[]

所以我只想知道

synonynm=wordnet.synsets('friend')[0]

还有这个

wordnet.synsets('friend')[1]

感谢您的指导

Answer 1

wordnet.synsets('friend')返回一个同义词集列表：

[Synset('friend.n.01'), Synset('ally.n.02'), Synset('acquaintance.n.03'), Synset('supporter.n.01'), Synset('friend.n.05')]

然后您可以通过其索引访问列表中的每个Synset，例如。列表中的第一个Synset是：

wordnet.synsets('friend')[0] # Synset('friend.n.01')
wordnet.synsets('friend')[0].name() # friend.n.01
wordnet.synsets('friend')[0].definition() # a person you know well and regard with affection and trust
wordnet.synsets('friend')[0].examples() # ['he was my best friend at the university']

这是一个代码段，为列表中的每个Synset打印名称，定义和示例：

from nltk.corpus import wordnet
for result in wordnet.synsets('friend'):
    print(result.name(), result.definition(), result.examples())

输出：

friend.n.01 a person you know well and regard with affection and trust ['he was my best friend at the university']
ally.n.02 an associate who provides cooperation or assistance ["he's a good ally in fight"]
acquaintance.n.03 a person with whom you are acquainted ['I have trouble remembering the names of all my acquaintances', 'we are friends of the family']
supporter.n.01 a person who backs a politician or a team etc. ['all their supporters came out for the game', 'they are friends of the library']
friend.n.05 a member of the Religious Society of Friends founded by George Fox (the Friends have never called themselves Quakers) []

请注意，在您的代码中，如果要在Synsets列表中获取索引2的示例，则应执行以下操作：

from nltk.corpus import wordnet
synonynm=wordnet.synsets('friend')[2]
synonynm.name() #related synonyms words
synonynm.definition() #definition of passed words
synonynm.examples()
