I read about Automatic Summarization in Medium from HN and got an idea for my second bot: posting summarizations on long Reddit posts. These are also know as TL;RDs on the internets.
I use the Python bindings for the Open Text Summarizer (OTS). This works by extracting the most important sentences in the text.
Since such a thing would only work on certain types of comments I verify that they are of sufficient length and only contain plain text (no lists, tables and others).
Results
The source code is available on GitHub and I ran the bot on CGTLDR.
The results have been incredibly disappointing. The comments made are sometimes useful, but they have produced little interest.
