Trying to subset and/or filter (essentially separate) a data frame object which has already been tokenized

问题

尝试对已经进行了标记的数据框对象进行子集和/或筛选(基本上是分开),以便数据框的每一行都以参议员和他们说的话、参议员和他们提出的法案或国会记录的标题开头。

我需要做的是保留识别出参议员和他们的讲话的行。当我将子集或筛选函数应用于我的数据框时,输出没有内容(请参见脚本的描述)。

#这是具有正则表达式的参议员名单
## "^"表示名字在字符串的开头
## "\\s"表示名字后应该有一个空格
## "(.*)"表示应该包括所有后续内容
sen_names <- c("^McCONNELL先生(R; Kentucky):\\s(.*)",&quot;^JOHNSON先生(D; South Dakota):\\s(.*)",&quot;^NICKLES先生(R; Oklahoma):\\s(.*)",&quot;^LEAHY先生(D; Vermont):\\s(.*)",&quot;^CONRAD先生(D; North Dakota):\\s(.*)",&quot;^BOXER女士(D; California):\\s(.*)",&quot;^BOXER女士(D; California):\\s(.*)",&quot;^SHELBY先生(R; Alabama):\\s(.*)",&quot;^MURKOWSKI女士(R; Alaska):\\s(.*)",&quot;^STEVENS先生(R; Alaska):\\s(.*)",&quot;^KYL先生(R; Arizona):\\s(.*)",&quot;^McCAIN先生(R; Arizona):\\s(.*)",&quot;^PRYOR先生(D; Arkansas):\\s(.*)",&quot;^LINCOLN女士(D; Arkansas):\\s(.*)",&quot;^FEINSTEIN女士(D; California):\\s(.*)",&quot;^ALLARD先生(R; Colorado):\\s(.*)",&quot;^CAMPBELL先生(R; Colorado):\\s(.*)",&quot;^DODD先生(D; Connecticut):\\s(.*)",&quot;^LIEBERMAN先生(D; Connecticut):\\s(.*)",&quot;^BIDEN先生(D; Delaware):\\s(.*)",&quot;^CARPER先生(D; Delaware):\\s(.*)",&quot;^GRAHAM L先生(R; South Carolina):\\s(.*)",&quot;^GRAHAM B先生(D; Florida):\\s(.*)",&quot;^NELSON C先生(D; Florida):\\s(.*)",&quot;^NELSON B先生(D; Nebraska):\\s(.*)",&quot;^CHAMBLISS先生(R; Georgia):\\s(.*)",&quot;^MILLER先生(D; Georgia):\\s(.*)",&quot;^AKAKA先生(D; Hawaii):\\s(.*)",&quot;^INOUYE先生(D; Hawaii):\\s(.*)",&quot;^CRAIG先生(R; Idaho):\\s(.*)",&quot;^CRAPO先生(R; Idaho):\\s(.*)",&quot;^DURBIN先生(D; Illinois):\\s(.*)",&quot;^FITZGERALD先生(R; Illinois):\\s(.*)",&quot;^BAYH先生(D; Indiana):\\s(.*)",&quot;^LUGAR先生(R; Indiana):\\s(.*)",&quot;^GRASSLEY先生(R; Iowa):\\s(.*)",&quot;^HARKIN先生(D; Iowa):\\s(.*)",&quot;^BROWNBACK先生(R; Kansas):\\s(.*)",&quot;^ROBERTS先生(R; Kansas):\\s(.*)",&quot;^BUNNING先生(R; Kentucky):\\s(.*)",&quot;^BREAUX先生(D; Louisiana):\\s(.*)",&quot;^LANDRIEU女士(D; Louisiana):\\s(.*)",&quot;^COLLINS女士(R; Maine):\\s(.*)",&quot;^SNOWE女士(R; Maine):\\s(.*)",&quot;^MIKULSKI女士(D; Maryland):\\s(.*)",&quot;^SARBANES先生(D; Maryland):\\s(.*)",&quot;^KENNEDY先生(D; Massachusetts):\\s(.*)",&quot;^KERRY先生(D; Massachusetts):\\s(.*)",&quot;^STABENOW女士(D; Michigan):\\s(.*)",&quot;^LEVIN先生(D; Michigan):\\s(.*)",&quot;^DAYTON先生(D; Minnesota):\\s(.*)",&quot;^COLEMAN先生(R; Minnesota):\\s(.*)",&quot;^COCHRAN先生(R; Mississippi):\\s(.*)",&quot;^COCHRAN先生(R; Mississippi):\\s(.*)",&quot;^TALENT先生(R; Missouri):\\s(.*)",&quot;^BOND先生(R; Missouri):\\s(.*)",&quot;^BAUCUS先生(D; Montana):\\s(.*)",&quot;^BURNS先生(R; Montana):\\s(.*)",&quot;^HAGEL先生(R; Nebraska):\\s(.*)",&quot;^ENSIGN先生(R; Nevada):\\s(.*)",&quot;^REID先生(D; Nevada):\\s(.*)",&quot;^GREGG先生(R; New Hampshire):\\s(.*)",&quot;^SUNUNU先生(R; New Hampshire):\\s(.*)",&quot;^CORZINE先生(D; New Jersey):\\s(.*)",&quot;^LAUTENBERG先生(D; New Jersey):\\s(.*)",&quot;^BINGAMAN先生(D; New Mexico):\\s(.*)",&quot;^DOMENICI先生(R; New Mexico):\\s(.*)",&quot;^CLINTON女士(D; New York):\\s(.*)",&quot;^SCHUMER先生(D; New York):\\s(.*)",&quot;^SCHUMER先生(D; New York):\\s(.*)",&quot;^SCHUMER先生(D; New York):\\s(.*)",&quot;^DORGAN先生(D; North Dakota):\\s(.*)",&quot;^DEWINE先生(

Trying to subset and/or filter (essentially separate) a data frame object which has already been tokenized so that each row of the df either begins with a Senator and what they said, a Senator and the bill they’re proposing, and a header of the Congressional record.

What I need to do is keep the rows that identify a senator and their speech. When I apply the subset or filter function to my df, the output has no content (see script for description).

I have uploaded a test environment to Google Drive that includes the list/dictionary of senators and one of the tokenized dfs. This is already setup with regex (and maybe this is where I’m going wrong?) It is accessible here: [test environment](https://drive.google.com/file/d/1mTZuu281JPDrEIwZlo_rgaRtV7X5EOMu/view?usp=share_link)

答案2

得分: 1

The regexes for the sen_names were wrong by just a bit. You were almost there.

我们只需稍微修正sen_names的正则表达式即可。你已经接近成功。

We have to escape the parenthesis and literal dots, as these are special characters. I also see no reason for (.*) at the end of the patterns.

我们需要转义括号和点号,因为它们是特殊字符。我也看不出在模式的末尾需要(.*)的原因。

After correcting the regexes, we can paste all sen_names into a single character scalar, separated by the OR special character (|), then do the matching on this single char element.

在修正正则表达式之后,我们可以使用paste将所有sen_names连接成一个单一的字符标量,用OR特殊字符(|)分隔,然后在这个单一字符元素上进行匹配。

With the following code, I could filter a data.frame of just two rows. I believe this example with two sen_names is an adequate minimal reprex:

使用以下代码,我可以筛选出仅有两行的数据框。我认为这个包含两个sen_names的示例是一个足够简化的表现示例:

sen_names <- c("^Mr\\. McCONNELL \\(R; Kentucky\\):\\s","^Mr\\. JOHNSON \\(D; South Dakota\\):\\s")
consolidated_sen_names <- paste(sen_names, collapse = "|")

aug_01_2003_speeches %>%
    filter(str_detect(speeches, consolidated_sen_names)) %>%
    tibble()
