Hello, I'm fairly new to Perl and I have a question about how to construct features using word tokens. Essentially, I have messages like "I like you." and I'd like to separate that into its word tokens, I, like, and you. Then, each word would represent a column feature and messages would have how many instances of that word token they have as their value. In this case, this message would have 1 1 1. I'd like to do this for a bunch of messages (and they would all share these features, meaning a lot would be 0). In a different programming language, I would iterate over each message, constructing columns as I go along, and finding how many of each word there is. However, with a lot of messages, I'm looking for a faster way to do this. Is there an easy way in Perl, or is there already code out there to do this? Thanks!
