中文文本挖掘

Question

我用中文分詞做文本挖掘。我改變了數據類型爲逗號和雙引號的數據框。所以wordcloud很奇怪。就像這樣：

我的語法如下： 檢查（d.corpus）

d.corpus <- Corpus(DataframeSource(data.frame(as.character(d.corpus)))) 
tdm <- TermDocumentMatrix(d.corpus, control = list(wordLengths = c(2, Inf))) 
m1 <- as.matrix(tdm) 
v <- sort(rowSums(m1), decreasing = TRUE) 
d <- data.frame(word = names(v), freq = v) 
wordcloud(d$word, d$freq, min.freq = 5, random.order = F, ordered.colors = F, 
    colors = rainbow(length(row.names(m1)))) 

如何修改數據？

我試圖拆句法：

d.corpus <- Corpus(DataframeSource(data.frame(as.character(d.corpus)))). 

爲什麼as.character(d.corpus)有3rows？

test1 <- as.character(d.corpus) 

Answer 1

我發現，我用循環編輯姓名（V）數據。

for (i in 1:length(names(v))) 
{ 
    names(v)[i] <- gsub('[\",]','',names(v)[i]) 
}
