    Great question, Ahuva.

    I think you will find this blog article of ours helpful.

    Our Chief of R&D says, "They are weighted according to relative 'importance' in the document. I would call the weighting algorithm ‘LM-boosted TextRank, with phrase-level combination’ if I was submitting {a response} to an NLP conference."

    I hope this is helpful!
