Porter Stemmer

An implementation of the Porter stemming algorithm in Rust. It operates over grapheme clusters rather than characters, so your input stream can mixed content.

Example

``` use unicodesegmentation::UnicodeSegmentation; use porterstemmer::stem;

let original = "Almost  forty  years  later,  these  fair information  practices  have  become  the standard  for  privacy  protection  around  the  world.  And  yet,  over  that same time  period,  we  have  seen  an  exponential  growth  in  the  use  of surveillance technologies,  and  our  daily  interactions  are  now  routinely  captured, recorded, and manipulated by small and large institutions alike.";

let tokenised_sentence = original.clone().unicode_words();

println!("Original:\n{}", original);
println!("Stemmed:\n{}", tokenised_sentence.map(stem).fold(String::new(), |last, next| { format!("{}{} ", last, next)}));

Original: Almost forty years later, these fair information practices have become the standard for privacy protection around the world. And yet, over that same time period, we have seen an exponential growth in the use of surveillance technologies, and our daily interactions are now routinely captured, recorded, and manipulated by small and large institutions alike.
