There is also TextTeaser (https://github.com/MojoJolo/textteaser). There is a version in Python and Scala. I believe is behind the article summarization bots on reddit.
I explored using it to generate talk summaries for https://www.findlectures.com and have been reasonably happy with it, although it's tough to get a summary that is succinct enough for search engine results.
