以互動問答方式建構中小學生自我學習系統

Abstract

網際網路有著許多豐富的資料，若我們想從網際網路裡學習知識，就必須透過網頁瀏覽方式或靠網站本身提供的檢索機制來查詢相關資料。但是，使用這些資訊檢索機制，對中小學生來說，可能很困難，這是因為必須先熟悉檢索機制與相關領域知識，而熟悉各個網站的檢索機制與使用檢索機制，對中小學生來說，在各方面領域知識還不太充足的情況下，實在是一件很困難的工作。因此，對中小學生來講，其最希望的學習方式，應該是直接告訴他們問題的答案及答案所在，而不是讓他們獨自摸索與彙整答案，這也是最好與最快速的自我學習方式。所以，本研究的目的，便是希冀善用各式內容網站知識，透過知識擷取技術與互動式問題回答機制，來縮短中小學生學習知識的流程及提高自我學習的興趣。

Web sites contain amount of documents (web pages) in response to a user’s information search or learning request. While a list of documents can be an appropriate response for the user, frequently it is not. Usually it would be better for the system to provide the answer itself instead of requiring the user to search for the answer in a set of documents. Thus, we have developed an architecture that augments Meta search agent so that they support Chinese natural language question answering. In this project we develop a new approach to build an interactive question answering system for student self-learning. Which we believe to be the first general-purpose, fully-automated Chinese question-answering system available on the web.
