我正在研究在 python 中嵌入文本。我发现两个文档与 Doc2vec 模型的相似之处。代码如下:
for doc_id in range(len(train_corpus)):
inferred_vector = model.infer_vector(train_corpus[doc_id].words) # it takes each document words as a input and produce vector of each document
sims = model.docvecs.most_similar([inferred_vector], topn=len(model.docvecs)) # it takes list of all document's vector as a input and compare those with the trained vectors and gives the most similarity of 1st document to other and then second to other and so on .
print('Document ({}): «{}»\n'.format(doc_id, ' '.join(train_corpus[doc_id].words)))
print(u'SIMILAR/DISSIMILAR DOCS PER MODEL %s:\n' % model)
for label, index in [('MOST', 0), ('SECOND-MOST', 1), ('MEDIAN', len(sims)//2), ('LEAST', len(sims) - 1)]:
print(u'%s %s: «%s»\n' % (label, sims[index], ' '.join(train_corpus[sims[index][0]].words)))
现在,从这两个嵌入的文档中,我如何才能从这些特定文档中提取一组语义相似的单词。
请帮帮我。
