<p>This dataset of Part-of-Speech (POS) tagged building codes contains 1,522 sentences from Chapters 5 and 10 of 2015 International Building Code. It adopts the original version of Penn Treebank tag set for the POS tags. It includes tagging results from 5 human annotators and 7 machine taggers. It also provides the most commonly chosen POS tag for each word by machine taggers and by human annotators. For detailed explanations of the meanings of the POS tags, please refer to <em>Building a Large Annotated Corpus of English: The Penn Treebank </em>[1]. For an explanation of the development of this dataset, please refer to the following paper [2].</p> <p>The authors would like to thank the National Science Foundation (NSF).
