Abstract
In the last two years, we have been developing
a multilingual web question answering system, which is aimed at
discovering answers to natural language questions in three different
languages: English, German and Spanish. One of its major components is
the module that
extracts answers to definition questions from the web.
This paper compares and provides insights into different techniques that
we have used
during these two years for tackling definition questions in Spanish.
Additionally, the present work
focuses its attention on new challenging issues regarding the language
phenomena that adversely affect the
answering process. In particular, in comparison with the analogous task
in English.
