摘要：Question Answering (QA) systems are gaining great importance due to the increasing amount ofweb content and the high demand for digital information that regular information retrievaltechniques cannot satisfy. A question answering system enables users to have a naturallanguage dialog with the machine, which is required for virtually all emerging online servicesystems on the Internet. The need for such systems is higher in the context of the Arabiclanguage. This is because of the scarcity of Arabic QA systems, which can be attributed to thegreat challenges they present to the research community, including the particularities of Arabic,such as short vowels, absence of capital letters, complex morphology, etc. In this paper, wereport the design and implementation of an Arabic web-based question answering system, whichwe called “JAWEB”, the Arabic word for the verb “answer”. Unlike all Arabic questionansweringsystems, JAWEB is a web-based application, so it can be accessed at any time andfrom anywhere. Evaluating JAWEB showed when compared to ask.com, the well-establishedweb-based QA system, JAWEB provided 15-20% higher recall. These promising results giveclear evidence that JAWEB has great potential as a QA platform and is much needed by ArabicspeakingInternet users across the world.
