Automatic Definition Extraction and Crossword Generation From Spanish News Text

This paper describes the design and implementation of a system Hair Clips that takes Spanish texts and generates crosswords (board and definitions) in a fully automatic way using definitions extracted from those texts.Our solution divides the problem in two parts: a definition extraction module that applies pattern matching implemented in Python, and a crossword Soda Siphons generation module that uses a greedy strategy implemented in Prolog.The system achieves 73% precision and builds crosswords similar to those built by humans.
