imperative: Intuitively Remark Sentences as Imperative

Description

Automatic imperative remarking.

Usage

imperative(dataframe, person.var, text.var, lock.incomplete = FALSE,
  additional.names = NULL, parallel = FALSE, warning = FALSE)

Arguments

dataframe

A data.frame object.

person.var

The person variable.

text.var

The text variable.

lock.incomplete

logical. If TRUE locks incomplete sentences (sentences ending with "|") from being marked as imperative.

additional.names

Additional names that may be used in a command (people in the context that do not speak).

parallel

logical. If TRUE attempts to run the function on multiple cores. Note that this may not mean a speed boost if you have one core or if the data set is smaller as the cluster takes time to create. With the mraja1spl data set, with an 8 core machine, imperative had 1/3 the running time.

warning

logical. If TRUE provides comma warnings (sentences that contain numerous commas that may be handled incorrectly by the algorithm).

Value

Returns a dataframe with a text variable indicating imperative sentences. Imperative sentences are marked with * followed by the original end mark.

Warning

The algorithm used by imperative is sensitive to English language dialects and types. Commas can indicate a choppy sentence and may indicate a false positive. Sentences marked with `AAVE` may be the use of African American Vernacular English and not an imperative sentence.

Examples

# NOT RUN {
dat <- data.frame(name=c("sue", rep(c("greg", "tyler", "phil", 
    "sue"), 2)), statement=c("go get it|", "I hate to read.", 
    "Stop running!", "I like it!", "You are terrible!", "Don't!", 
    "Greg, go to the red, brick office.", "Tyler go to the gym.", 
    "Alex don't run."), stringsAsFactors = FALSE)

imperative(dat, "name", "statement", , c("Alex"))
imperative(dat, "name", "statement", lock.incomplete = TRUE, c("Alex"))
imperative(dat, "name", "statement", , c("Alex"), warning=TRUE)
imperative(dat, "name", "statement", , c("Alex"), warning=TRUE,  
    parallel = TRUE)
# }
