UXWN: analysis and improvement of a logical form resource for NLP

Logical Form is an exceptionally important linguistic representation for highly demanding semantically related tasks like Question Answering. In this work I present different types of LF and in particular I investigate those resources that provide a LF of the WordNet Glosses. I then take a closer look to one of them, eXtended WordNet, by analysing its weaknesses and strengths. After classifying the most common errors of this resource, I semi automatically correct them and the result is a new resource: United eXtended WordNet.
