TextRank is a system for unsupervised extractive summarization that relies on an innovative application of iterative graph-based ranking algorithms to graphs encoding the cohesive structure of texts. An important characteristic of the system is that it does not rely on any language-specific knowledge resources or any manually constructed training data, and thus it is highly portable to new languages or domains.
