如何将列表转换为R中的语料库? [英] How transform a list into a corpus in r?

问题描述

在此

In this question I asked how to split a huge dataframe to create a corpus. Thanks to the answer I was able to create a list from a dataframe. My problem was still obtaining a corpus from the list I created in order to do some text mining and cluster the data according to the search term.

推荐答案

为解决此问题，我将tm包的as.VCorpus函数应用于我之前创建的列表:

To solve this problem I just applied the as.VCorpus function of the tm package to the list I created before:

new_corpus <- as.VCorpus(new_list)

检查新对象是否为语料库:

Check if the new object is a corpus:

class(new_corpus)
[1] "VCorpus" "Corpus" 

因此，我创建了一个易失性语料库".如R文档中所述:

I thus created a "volatile corpus". As written in the R documentation:

易失性语料库已完全保留在内存中，因此所有更改仅影响相应的R对象.

A volatile corpus is fully kept in memory and thus all changes only affect the corresponding R object.
