我正在努力学习R中的文本挖掘

在尝试挖掘google新闻和财经页面时，我遇到了使用tm.plugin.webmining包的问题（请参阅下面附带的代码和错误消息）

如果能得到任何帮助，我将不胜感激

使用GoogleNewsSource

googlenews <- WebCorpus(GoogleNewsSource("Microsoft"))
Unknown IO errorfailed to load external entity "http://news.google.com/news?hl=en&q=Microsoft&ie=utf-8&num=100&output=rss"
Error: 1: Unknown IO error2: failed to load external entity "http://news.google.com/news?hl=en&q=Microsoft&ie=utf-8&num=100&output=rss"

library(tm.plugin.webmining)
library(purrr)

company <- c("Microsoft", "Apple", "Google", "Amazon", "Facebook",
             "Twitter", "IBM", "Yahoo", "Netflix")
symbol <- c("MSFT", "AAPL", "GOOG", "AMZN", "FB", "TWTR", "IBM", "YHOO", "NFLX")

download_articles <- function(symbol) {
  WebCorpus(GoogleFinanceSource(paste0("NASDAQ:", symbol)))
}

stock_articles <- data_frame(company = company,
                             symbol = symbol) %>%
  mutate(corpus = map(symbol, download_articles))
failed to load HTTP resource
Error in mutate_impl(.data, dots) : 1: failed to load HTTP resource

googlenews问题在于NASDAQ:TWTR
。从公司中删除“Twitter”
和从符号中删除“TWTR”
可以解决此错误
company <- c("Microsoft", "Apple", "Google", "Amazon", "Facebook", "Netflix")
symbol <- c("MSFT", "AAPL", "GOOG", "AMZN", "FB", "NFLX")

download_articles <- function(symbol) {
  WebCorpus(GoogleFinanceSource(paste0("NASDAQ:", symbol)))
}
stock_articles <- data_frame(company = company,
                             symbol = symbol) %>%
  mutate(corpus = map(symbol, download_articles))
stock_articles
