title: SNOR v1: Structured and Normalized OpenReview Reviews and Comments

description: 38,262 linked records from OpenReview submissions to the ICLR (2017-2025) and Neurips (2021-2025) Machine Learning conferences. Paper submissions are linked to Semantic Scholar, a dynamic academic graph. Also provided are 462,995 structured comments from reviewers. Semantic Scholar includes information about authors, citations, and a variety of other metadata. By default, linked rows contain citation counts, venue information, Specter embeddings and author ids - but other information is easily retrievable using the SemanticScholar API.

In addition to the paper information, there are also 462,995 structured comments from reviewers. These comments include references to papers, anonymous author signatures, and arbitrary content (typically in the form of title:content blocks which render in OpenReview). Reviews are distingushed from other comments by the 'is_review' field, which is set to True for reviews. These comments will also have a numeric rating and confidence score. Finally, all comments have a reply_to_id field, which links to the id of the paper that the comment is replying to. Review comments will have a reply_to_id that links to the id of the paper they are reviewing. 

 

Example comment:

        {'conference_id': 'iclr2017',
        'paper_id': 'B1jnyXXJx',
        'comment_id': 'BJPZL-vmx',
        'signature': 'ICLR.cc/2017/conference/paper4/AnonReviewer1',
        'content': {
          'title': 'hyperparameter optimization and momentum vs CPN',
          'question': "The hyperparameters of gradient descent seem to be chosen once and fixed. 
                       Would optimizing the gradient descent hyperparameters lead to equivalent 
                       performance as the CPN method?\n\nFollowing up on another reviewer's 
                       question: CPN seems closely related to momentum. Can you provide a clear 
                       example to show how CPN is qualitatively distinct from momentum? (I believe
                       it is, but this could be clarified further in the paper)"
