TechKnAcq Concept Dependency Data

Release 1, 2016-08-08

This is data to accompany this publication:

Jonathan Gordon, Linhong Zhu, Aram Galstyan, Prem Natarajan, and Gully Burns. 2016. Modeling Concept Dependencies in a Scientific Corpus. In Proceedings of ACL.

The files are:

  • Automatic dependency scores.csv: These are the weights for concept dependency edges predicted by the methods described in the paper. The more positive a score is, the stronger the prediction that topic T1 would help a learner to understand T2?

  • Human judgments.csv: These are the full judgments collected about the scientific topics from 8 academics with different levels of expertise in the domain (NLP). For a pair of topics T1 and T2, we report the judgments for how coherent T1 is, how coherent T2 is, how similar T1 and T2 are to each other, how much T1 would help you understand T2, and how much T2 would help you to understand T1. Responses are on a three-point scale:
    1 Not at all.
    2 Somewhat.
    3 Very much.

  • Topic word counts.txt.bz2: These are the (bzip2-compressed) counts for the bigrams associated with each topic, as produced by Mallet.

  • Topic model names.csv: The human-generated names for each of the topics. Topics that didn't have a clear interpretation are named 'Miscellany' with a unique numeric identifier.

Inputs not included in this release are:

  • The ACL citation network. We use the 2013 release of the ACL Anthology Network, which is available from
  • The ACL Anthology text corpus the topic model was learned from. We don't have the permissions to publicly distribute this at present, but it is available by request.
