human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "from social data mining to forecasting socio economic crises"
  Abstract: The purpose of this White Paper of the EU Support Action “Visioneer”(see www.visioneer.ethz.ch) is to address the following goals: #R##N##R##N#1.#R##N##R##N#Develop strategies to quickly increase the objective knowledge about social and economic systems.#R##N##R##N##R##N##R##N##R##N#2.#R##N##R##N#Describe requirements for efficient large-scale scientific data mining of anonymized social and economic data.#R##N##R##N##R##N##R##N##R##N#3.#R##N##R##N#Formulate strategies how to collect stylized facts extracted from large data set.#R##N##R##N##R##N##R##N##R##N#4.#R##N##R##N#Sketch ways how to successfully build up centers for computational social science.#R##N##R##N##R##N##R##N##R##N#5.#R##N##R##N#Propose plans how to create centers for risk analysis and crisis forecasting.#R##N##R##N##R##N##R##N##R##N#6.#R##N##R##N#Elaborate ethical standards regarding the storage, processing, evaluation, and publication of social and economic data.
