Abstract

The invention discloses a topic viewpoint strength calculating method based on viewpoint statement confidence level. The method comprehensively considers the confidence level of webpages and the supporting degree of the webpages to topic viewpoint statements, the confidence level of each viewpoint statement in topic viewpoints is calculated by combining factors on two aspects, and finally strength values of the topic viewpoints are obtained by calculating the sum of the confidence levels of multiple viewpoint statements. By the adoption of the method, a user can be helped to quantificationally know the viewpoint strengths of different viewpoints, distinguish primary viewpoints and secondary viewpoints and disclose the details of different topic viewpoints.
