For factoid questions our redundancy-based approach using a modified version of ARANEA was enhanced further. Our list question answerer uses a clustering method to group the candidate answers that co-occur together. It also uses the target and question keywords as spies to pinpoint the right cluster of candidates. To answer other types of questions, our system extracts from Wikipedia articles a list of interest-marking terms and uses them to extract and score sentences from the AQUAINT-2 and BLOG document collections using various interest-marking triggers.s using various interest-marking triggers.
