Abstract

We present the second version of the Prodicos query answering system which was developed by the TALN team from the LINA institute. The main improvements made concern in the one hand, the use of external knowledge (Wikipedia) to improve the passage selection step. And on the other hand, the answer extraction step is improved by the determination of four different strategies for locating the answer to a question regarding its type. Afterwards, for the passage selection and answer extraction modules, the evaluation is put forward to justify the results obtained.
