PyTeaser

PyTeaser takes any news article and extract a brief summary from it. It's based on the original Scala project.

Summaries are created by ranking sentences in a news article according to how relevant they are to the entire text. The top 5 sentences are used to form a "summary". Each sentence is ranked by using four criteria:

  • Relevance to the title
  • Relevance to keywords in the article
  • Position of the sentence
  • Length of the sentence

Installation:

pip install pyteaser

Note: if you're installing on Windows, you have to install one of the dependency package lxml manually using:

easy_install lxml==2.3.3
