Infringement data capture priority evaluation method and network monitoring system thereof

The invention relates to an infringement data capture priority evaluation method and a network monitoring system thereof. The method comprises the steps that S1, according to a search result, first interest information I1, second interest information I2, a title S, work information K, keyword information K1, a current work priority w1, a current keyword priority k1, a page number p in the search result and ranking ps are obtained; S2, a ranking factor cp=1/(p*31+ps)*F is calculated, min(cp) is made to be equal to 1, and cp is rounded upwards; wherein F is an adjustment number so as to ensure that a calculation result interval is a positive number; S3, the work information similarity ws=sim(S,K) is calculated, and sim(S,K) is defined as the ratio of the maximum number of characters appearing in the character string S in sequence in the character string K to the total number of characters contained in K; s4, keyword similarity ks=sim(S,K1) is calculated, wherein the sim(S,K1) is definedas the ratio of the maxim
