  • Using Google Pagerank on the sentence network to rank sentences in order of importance

For finding keywords, this algorithm basically consists of.

  • Extract words following one another to construct a word network
  • Using Google Pagerank on the word network to rank words in order of importance
  • Constructing keywords - which are the combination of relevant words identified by the Pagerank algorithm which follow each other
