Abstract: In order to promote the development of tourism information, a digital multimedia intelligent question?answering system dealing with tourism consulting information was designed. The system makes up of the host and mobile terminals. The mobile terminals are employed to collect travel advisory information from tourists. The question analysis module of the host is adopted to extract information keywords, and bring them in using the digital multimedia database by means of indexer. The data related to information entities, attributes, and relationship is matched with the travel advisory information in virtue of the digital multimedia technology to get the candidate quiz answers. The similarity of tourism consulting information is calculated. The candidate quiz answers are arranged according to the calculated results, and are displayed on the relevant mobile terminal. The experiment results show that the designed system has strong reliability, and can deal with the concept relation of tourism consulting information.
