I wrote about messie here the other day and what I use it for is that I want to automatically download pages and find keywords in their content. Say for instance, this article should have the keywords “keywords, highscore, ruby” and so on. Just a list of tags that describe this page’s content.
Highscore exactly does that. Give it a string and a blacklist (you don’t want to have words like “like, you, want” in your keywords or would you?) and it gives you all the important words back. You can configure highscore to rate words based on their characteristics, e.g. upper case words should have a double weight, longs words (say, the threshold is 20 chars) should have half, and so on.
- get the top n words
- blacklist words via a file, array or string
- default blacklist in the gem
- merge different Keywords objects (e.g. from different sources)
- configureable to rank different types of words differently (uppercase, long words, etc.)
- String has it’s own keywords method that you can use
- detect the language of a string via “indicator words”
- define a blacklist file per language (based on language detection)
- fine grain the default blacklist (just a few words atm)
keywords = "This is just a very basic example, look at the readme to see what's possible using highscore.".keywords keywords.rank.each do |word| puts word.text end
gem install highscore
