tfidf_ja's Issues
tfidfの値が単語によらず、同じ値になってしまいます
ruby本体のバージョン:ruby-1.9.2-p180(MacOS,Ubuntu環境ともに)
tfidf_jaのバージョン:2.0.0および0.1.1において
表題のとおりtfidfの値が単語によらず、同じ値になってしまいます。
具体的には
require 'rubygems'
require 'tfidf_ja'
p TfIdf::Ja.new.tfidf(['この', '文章', 'から', 'TFIDF', '値', 'を', '取得', 'する'])の値が
# >> {"この"=>13.368957861079517, "文章"=>13.368957861079517, "から"=>13.368957861079517, "TFIDF"=>13.368957861079517, "値"=>13.368957861079517, "を"=>13.368957861079517, "取得"=>13.368957861079517, "する"=>13.368957861079517}となってしまいます。
doc/idf.dicを見ると13.368957861079517という値はaverageとひもづいているようなので
平均値をとってきてしまっているように思われます。
非常に使ってみたいので、修正していただけるとありがたいです。
