DESCRIPTION:Natural language processing used to rely on formal methods in 
 its early days\, and this included formal theories of syntax where sentenc
 e structure was of relevance. In the statistical era\, the focus shifted t
 o annotation schemes such as Penn Treebank and Universal Dependencies\, wh
 ich still rely on formal theory in their origins but prioritize simplicity
  over consistency. Now in the era of deep learning\, while most training f
 orgoes any annotation\, annotated corpora remain crucial for evaluation an
 d interpretation of the output of language models. In this context\, it is
  important that the theory underlying the annotation be consistent and\, f
 urthermore\, developed independently of NLP tasks. I will talk about the r
 ecent work we did with the Head-driven Phrase Structure Grammar theory of 
 syntax (HPSG). We have worked with HPSG to grow and improve existing corpo
 ra of Spanish and to improve the parsing speed of the English Resource Gra
 mmar\, so that the English corpora can be grown more easily.  Currently\,
  we are working with the English Resource Grammar to study linguistic prop
 erties of texts generated by LLMs\, including looking for any systematic d
 ifferences with similar texts written by people. I will talk about this wo
 rk in progress at the end of the talk.
