如何基于word2vec查找同义词 [英] How to find synonyms based on word2vec

问题描述

我正在使用 Python 中的 gensim 处理 word2vec 模型，但我发现结果是具有相同主题的单词，同义词只是结果的一部分.

I 'm working on word2vec model using gensim in Python, but I found that the result are the words having the same theme, synonyms are only part of the result.

推荐答案

Word2vec 倾向于表示相似的词——但您可能已经看到，它学习的相似性不仅仅包括纯同义词.

Word2vec tends to indicate similar words – but as you've probably seen, the kind of similarity it learns includes more than just pure synonyms.

例如，word2vec 相似性包括出现在相似上下文中的单词，例如包括甚至对立的替代词.(毕竟，'hot' 和 'cold' 在很多方面都是非常相似的词——都是形容词，主要与温度有关，也比喻用于同类的非温度上下文中.只有在它们对比时，它们才是反义词.)

For example, word2vec similarities include words that appear in similar contexts, such as alternatives including even opposites. (After all, 'hot' and 'cold' are very similar words in many ways – both adjectives, primarily relating to temperature, and also figuratively used in the same sorts of non-temperature contexts. Only in their contrast are they antonyms.)

您可能需要使用其他技术(可能与 word2vec 配合使用)进行纯同义词发现.

You'll likely need to use other techniques (perhaps in concert with word2vec) for pure-synonym discovery.
