Propositional Forms of Judgemental Interpretations

BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:

@booklet{EasyChair:221,
  author    = {Tao Xue and Zhaohui Luo and Stergios Chatzikyriakidis},
  title     = {Propositional Forms of Judgemental Interpretations},
  doi       = {10.29007/kv25},
  howpublished = {EasyChair Preprint 221},
  year      = {EasyChair, 2018}}
