A notebook computer transmits a distribution. confirmation request including a content attribute. A data communication card performs a matching test for the attribute and notifies of a matching result. When a reservation receiving application requests to start reservation receiving, the data communication card synchronizes with a channel for broadcast to start transferring received data to the notebook computer, and switches a state display to STAND-BY state 2. The reservation receiving application sends a receiving end request upon detection of end of the content. The data communication card stops receiving the broadcast channel and returns the state display to STAND-BY state 1.

The invention relates to a method for querying a hierarchical semantic venation document, which is applied to the query of an unstructured document and can carry out complicated query and deeper knowledge acquisition, such as network document query, questionnaire survey document query, and the like. In the method, the query intention of a user is expressed by a query tree, the query semantic venation is expressed by a leaf node of the query tree, namely a query clause, and a logical operation relation among subnodes is expressed by a branch node. When whether a document is the document needed by the user or not is tested, the deep search and test are carried out according to the query tree. If a node is a query clause node, a semantic venation matching test is carried out; if the node is the branch node, the logical operation is carried out. The current node decides a self return value according to a return value of the subnode. Finally, if the return value of a root node is true, the current tested document is selected as the document needed by the user.
