Abstract:
1. A method for monitoring abnormal state of Internet information based on a dictionary of hot words that users have interest in, the method comprising: 1) obtaining and storing current date word-frequency data of common words appearing in current date web pages in a database, wherein the step of obtaining includes: 2) combining with the dictionary of hot words that the users focus on to determine current date keywords of each of the web pages, and merging the current date keywords associated with the web pages to obtain a list of the current date keywords of the Internet information {ti, i=1 . . . M}, wherein M is number of the current date keywords in the list of current date keywords; 3) determining a weight for each current date keyword by a computer system, comprising: defining qi=1/(cein(σi)), wherein cein( ) is a round-up function, a weight wi of a keyword ti satisfies: wherein i=1 corresponds to the current date keyword with lowest current date word-frequency fi; 4) determining an abnormal threshold of the current date keywords by the computer system: for a current date keyword ti, defining an abnormal threshold value as σi′=σi+c (wi/w1), wherein c is a constant representing expansion of abnormal threshold, which is defined by the users according to the users' experiences; and 5) detecting an abnormal level of the current date keywords to determine current date hot Internet information, which comprises:
