This paper proposes a web retrieval system with extended queries generated from the contents of Wikipedia.By using the extended queries, we aim to support user's retrieval and knowledge acquisition. To extract extended query items, we make much of hyperlinks in Wikipedia in addition to the related word extraction algorithm.We evaluated the system through experimental use of it by several examinees and the questionnaires to them.Experimental results show that our system works well for user's retrieval and knowledge acquisition.
