The invention discloses a hot event detection method and device, wherein the method comprises the following steps of acquiring a microblog data within a current time period in a social networking service; segmenting the words to the content of a plurality pieces of microblogs in the microblog data and counting the occurrence number of each word obtained by segmenting the words in the microblog data; acquiring the occurrence number of each word in a history microblog data within a history time period in the social networking service, wherein the length of time of the history time period and that of the current time period are equal; comparing the occurrence number of each word in the microblog data and that in the history microblog data, and determining the hot words in the microblog data; acquiring the microblogs including the hot words in the microblog data; clustering the microblogs including the hot words, determining the hot events in the microblog data. Through selecting the microblogs including the hot words from the microblog data within the current time period in the social networking service and clustering the microblogs including the hot words, the microblog number during clustering is decreased and the efficiency for obtaining obtain the hot events through clustering is improved.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a hot spot event detection method and device. Background technique [0002] Weibo has been developing at an astonishing speed since its birth to the present. The number of registered users of the two largest microblog platforms in China, Sina and Tencent, has already exceeded 500 million. Especially in emergencies and hot events, Weibo's scale of influence and speed of dissemination surpass ordinary blogs and traditional news media. At present, the method of detecting hot events from massive microblog data is mainly as follows: obtain massive microblog data, use Canopy clustering algorithm or k-means clustering algorithm to cluster massive microblog data, and obtain hot events. [0003] However, in the existing technology, there are too many microblogs in the massive microblog data, and most of the microblogs in the massive microblog data have nothing to do with hot ev...
