它应该是表示为单词袋"的语料库.或者，是的，术语计数列表.

It should be a corpus represented as a "bag of words". Or, yes, lists of term counts.

正确的格式是Gensim网页上的第一个教程中定义的corpus格式. >(这些非常有用).

The correct format is that of the corpus defined in the first tutorial on the Gensim webpage (these are really useful).

也就是说，如果您具有Radim教程中定义的dictionary和以下文档，

Namely, if you have a dictionary as defined in Radim's tutorial, and the following documents,

doc1 = ['big', 'data', 'technique', 'lots', 'of', 'cash']
doc2 = ['this', 'document', 'has', 'words']
docs = [doc1, doc2]

然后，您的语料库(用于LDA)应该是以下形式的元组列表的可迭代对象(例如列表):(dictKey, count)，其中dk指术语的字典键，并计数是它在文档中出现的次数.

then your corpus (for use with LDA) should be an iterable object (such as a list) of lists of tuples of the form: (dictKey, count), where dk refers to the dictionary key of a term, and count is the number of times it occurs in the document. This is done for you with

corpus = [dictionary.doc2bow(doc) for doc in docs]

该doc2bow函数的意思是文档到单词袋".

That doc2bow function means "document to bag of words".
