rankSentencesCentralToKeyphrase()
function rankSentencesCentralToKeyphrase(sentencesWithKeyphrases, options): Object[]
Rank sentences based on their centrality to key phrases. This function implements the TextRank algorithm to weight each sentence based on the number of key phrases it shares with other sentences. It creates a weighted graph where edges connect sentences to matching keyphrases, then performs random walks to distribute probabilities.
