Héctor {Martínez Alonso}

I am a post-doctoral fellow in INRIA - Paris 7 at the Almanach team. My research interests are centered on lexical semantics, dependency syntax, semi-supervised learning and linguistic annotation.
You can contact me at hector DOT martinez-alonso AT inria DOT fr or at my LinkedIn profile.

Data and tools

  • Regpol The regular-polysemy datasets in English, Danish and Spanish from my doctoral dissertation, and the Danish supersense-annotated SemDax corpus, as well as a supersense tagger trained from it.
  • I have been involved in the conversion of the Catalan, Danish and Spanish treebanks of Universal Dependencies UD.
  • Here is also the unsupervised dependency parser for UD from EACL’17.
  • In my fairly messy github contributions you can find smalltools, a collection of little Python scripts, including a bootstrap-sample significance tester which keeps coming in handy.
