Abstract

The invention discloses a situation searching method based on a body. The method aims at resolving the problems in the prior art of poor accuracy, insufficient personality, intelligent deficiency, situation overlooking and the like. The method includes the steps that 1 a webpage situation analysis and indication module analyzes a collected webpage and indicating webpage situation information; 2 a user situation excavation and indication module achieves excavation and indication of user situation and conducts achievement with the step1 simultaneously; 3 a situation index module designs an index structure melted in webpage situation information; 4 a situation expansion module achieves situation expansion to form inquiry situation, the situation expansion refers to utilizing user situation to conduct expansion on inquiry words on situation grade and limit context of the inquiry words to form inquiry situation; and 5 a situation inquiry processing module achieves situation inquiry and processing. The step 5 includes 1) situation recommendation, 2) situation search; and 3) situation sequencing. Sequencing results can be provided into a user inquiry interface.
