as_sbo_dictionary function

Coerce to dictionary

Coerce objects to sbo_dictionary class.

as_sbo_dictionary(x, ...)

## S3 method for class 'character'
as_sbo_dictionary(x, .preprocess = identity, EOS = "", ...)

Arguments

• x: object to be coerced.
• ...: further arguments passed to or from other methods.
• .preprocess: a function for corpus preprocessing.
• EOS: a length one character vector listing all (single character) end-of-sentence tokens.

Returns

A sbo_dictionary object.

Details

This function is an S3 generic for coercing existing objects to sbo_dictionary class objects. Currently, only a method for character vectors is implemented, and this will be described below.

Character vector input: Calling as_sbo_dictionary(x) simply decorates the character vector x with the class sbo_dictionary attribute, and with customizable .preprocess and EOS attributes.

Examples

dict <- as_sbo_dictionary(c("a","b","c"), .preprocess = tolower, EOS = ".")
