Title
Automatic Acquisition of Lexico-semantic Knowledge for QA
Abstract
We present an experiment for finding semantically similar words on the ba- sis of a parsed corpus of Dutch text and show that the acquired informa- tion correlates with relations found in Dutch EuroWordNet. Next, we demon- strate how the acquired knowledge can be used to boost the performance of an open-domain question answering sys- tem for Dutch. Automatically acquired lexico-semantic information is used to improve the recall of a method for ex- tracting function relations (such as Wim Kok is the prime minister of the Nether- lands) from corpora, and to improve the precision of our QA system on general WH-questions and definition questions.
