The invention discloses a Web news retrieval method based on event analysis. The Web news retrieval method based on the event analysis comprises the following steps of: setting two types of input frames of an event term Qe and a bound term Qc, and obtaining a query term Q={Qe, Qc}; selecting the title (T), the first paragraph (FP) and the last paragraph (LP) of Web news di to represent di, wherein di={T, FP, LP}; calculating the weight of each part of characteristic term of the di={T, FP, LP}; setting the weight of the characteristic term in the query term to be one; calculating the relevancy R(Q, di) of the query term Q and the news di; and according to the relevancy R(Q, di), carrying out descending order, and outputting a retrieval result. According to the method, the functions of different terms in a query content are distinguished, a computation method for the relevancy of the event query term and the Web news is proposed by combining with an event movement element, the importance of the Web news title and distance between the event term and the bound term, and the retrieval accuracy of the event-type Web news can be obviously improved.
