human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "identifying clickbait posts on social media with an ensemble of linear models"):
  Abstract: The purpose of a clickbait is to make a link so appealing that people click on it. However, the content of such articles is often not related to the title, shows poor quality, and at the end leaves the reader unsatisfied. #R##N#To help the readers, the organizers of the clickbait challenge (this http URL) asked the participants to build a machine learning model for scoring articles with respect to their "clickbaitness". #R##N#In this paper we propose to solve the clickbait problem with an ensemble of Linear SVM models, and our approach was tested successfully in the challenge: it showed great performance of 0.036 MSE and ranked 3rd among all the solutions to the contest.

Includes members:
  Member "the clickbait challenge 2017 towards a regression model for clickbait strength":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "clickbait sensational headline generation with auto tuned reinforcement learning")
  Member "the numpy array a structure for efficient numerical computation":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a deep unsupervised feature learning spiking neural network with binarized classification layers for emnist classification")
