Center node: "tutorialbank a manually collected corpus for prerequisite chains survey extraction and resource recommendation"
  Abstract: The field of Natural Language Processing (NLP) is growing rapidly, with new research published daily along with an abundance of tutorials, codebases and other online resources. In order to learn this dynamic field or stay up-to-date on the latest research, students as well as educators and researchers must constantly sift through multiple sources to find valuable, relevant information. To address this situation, we introduce TutorialBank, a new, publicly available dataset which aims to facilitate NLP education and research. We have manually collected and categorized over 6,300 resources on NLP as well as the related fields of Artificial Intelligence (AI), Machine Learning (ML) and Information Retrieval (IR). Our dataset is notably the largest manually-picked corpus of resources intended for NLP education which does not include only academic papers. Additionally, we have created both a search engine and a command-line tool for the resources and have annotated the corpus to include lists of research topics, relevant resources for each topic, prerequisite relations among topics, relevant sub-parts of individual resources, among other annotations. We are releasing the dataset and present several avenues for further research.

Connected through hyperedge HE-1 (induced by source paper "a summarization system for scientific documents"):
  with members:
    - "scisummnet a large annotated corpus and content impact models for scientific paper summarization with citation networks"
    - "identification of tasks datasets evaluation metrics and numeric scores for scientific leaderboards construction"
    - "multi task identification of entities relations and coreference for scientific knowledge graph construction"
    - "cl scholar the acl anthology knowledge graph miner"
    - "scientific paper summarization using citation summary networks"
