| With the rapid development of the Internet, a variety of data, information complex, difficult for users to search for desired content from a one-time, information distribution can be customized according to user needs to push content, but the traditional subscription language or too simple expression can not be detailed user requirements, or too difficult for users to grasp the complexity of natural language interfaces subscribe for this contradiction is the solution.The main contents of this paper is to design and implement an XML-based publish-subscribe system of natural language interfaces subscribe to the structure and function. Structured information and content information of XML Schema contains easy to convert natural language elements, studied the natural language elements into XPath standard subscription template customization language studies based on context and semantics subscription extended to the full covering user semantics, design interactive Subscribe expansion modules, user-friendly to use.The main innovation is to propose a thesis based on natural language parsing XML Schema interface implementations, while the design of a system suitable for publish-subscribe subscribe expansion module contains user interaction. The use of natural language interfaces subscription XML-based publish-subscribe system characteristics, avoiding the traditional database semantics of natural language interface to complex interdependence analysis, parsing through the XML Schema to achieve the same effect and objectively reduces system overhead. Subscribe expansion module combines the application context analysis and body, while the introduction of user interaction to participate, making coverage more comprehensive subscription.Paper proposed natural language interface scheme to subscribe to Internet and mobile network platforms, not only to ensure that users easy access to information of interest for retrieving more semi-structured information, has an important significance push. |
