classify_with_score and scored_categories return undefined?

[cheeyeo]

Hi

I tried running ClassifierReborn::LSI from the example in the README and when invoking the 'classify_with_score' and 'scored_categories' methods, it returns undefined? Am I calling it wrong?

lsi = ClassifierReborn::LSI.new

strings = [ ["This text deals with dogs. Dogs.", "a"],
            ["This text involves dogs too. Dogs!", "a"],
            ["This text revolves around cats. Cats.", "b"],
            ["This text also involves cats. Cats!", "b"],
            ["This text involves birds. Birds.", "c"]]

strings.each {|x| lsi.add_item x.first, x.last}

# NoMethodError
scored_categories = lsi.scored_categories("dog bird cat")

# NoMethodError
lsi.classify_with_score("test")

I also noticed that these methods are not in the gem version pulled from rubygems.org? The LSI class differs from the master branch here in the repo?

@cheeyeo the readme might be reflecting current master which has (in the last few days) undergone some fairly significant changes. Please use the master branch for those or find the readme at the version you're running.

@parkr Thanks for the prompt reply! Thought I was losing my mind for a moment 👍
