Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] At present, the traditional sentiment analysis technology is mainly carried out at the level of documents and sentences. The main task is to identify whether the emotions contained in documents and sentences are positive or negative. In the integrated seminar scene, because the participants often express their opinions on a certain aspect of the field (ie, the evaluation object), ...

Abstract

The invention provides a fine-grained viewpoint mining method for a comprehensive integration discussion scene. Through a conditional random field model, a real-time evaluation object in a real-time discussion text in the comprehensive integration discussion scene and a real-time viewpoint word corresponding to the real-time evaluation object can be extracted; and through the field emotion knowledge base, the emotion tendency of the real-time viewpoint word can be determined. In the embodiment of the invention, fine-grained level viewpoint mining can be carried out on the real-time discussion text oriented to the comprehensive integration discussion scene, so that viewpoints of conventioneers on various aspects of the target field are mined, the conventioneers can conveniently master changes and trends of the discussion viewpoints in time, and the conference discussion efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a fine-grained opinion mining method for comprehensive integration discussion scenarios. Background technique [0002] The essence of the comprehensive integrated seminar hall system is to guide people to integrate relevant experience, theory, knowledge, information and data to the greatest extent through the combination of man and machine and group discussion when dealing with open complex systems, and through the interaction between group members. Mutual stimulation and collective processing of the above resources can realize the emergence of group wisdom and gain a better understanding of complex systems. This clearly elevates the individual wisdom in the synthesis method to group wisdom, and significantly enhances the operability of the open complex system methodology. [0003] In the integrated discussion scenario, participants can conduct qualitative discuss...
