description Overview

LexRank

LexRank is an unsupervised, graph-based method for extractive text summarization. It represents sentences as nodes, connects sentences according to lexical similarity, and applies an eigenvector centrality calculation related to PageRank to identify sentences that are important within the resulting network. The method is used to select representative sentences from one document or a collection of...
