Embodiment Construction

[0015] A method for constructing a position analysis model based on the evaluation object camp, such as figure 1 As shown, for the comment information of social media on the Internet, an object camp dictionary is constructed. Using the method of dictionary-review information matching, extract the sentences that obviously have the characteristics of the object camp, as the learning corpus of object camp judgment, construct the object camp judgment model, and complete the judgment of the comment information object camp. The stance of the comment information is manually marked, and it is used together with the target camp and comment information as the input of the stance analysis model, and the stance analysis model is obtained through training.

[0016] Concrete content of the present invention includes:

[0017] (1) Construction of object camp judgment model

[0018] 1. Object camp dictionary construction

[0019] In order to facilitate the construction of the object camp j...

Abstract

The invention discloses a position analysis model construction method based on an evaluation object camp, comprising the following steps: step 1, constructing an object camp dictionary; 2, constructing a judging corpus of an object camp; 3, constructing an object camp judgment model; 4, constructing a standpoint analysis corpus; Step 5, constructing the position analysis model. Compared with the prior art, the positive effect of the invention is: the analysis speed of the position analysis model constructed by the method of the invention to the target object is fast, far higher than the manualjudgment; Secondly, the accuracy of the model can reach 72.54%, and can analyze some minority positions. Meanwhile, the training corpus construction work is small, only need to produce a small-scalecorpus, the model can be trained. In summary, when analyzing the position of the target object, the position analysis model of the invention not only saves the human cost and reduces the workload, butalso improves the efficiency and accuracy of the position analysis of the target object.

Description

technical field [0001] The invention relates to a method for constructing a position analysis model based on an evaluation object camp. Background technique [0002] When analyzing the position (commendative, derogatory, neutral, etc.) of massive comment information, the method of manually judging the position requires a lot of manpower and is inefficient. In addition, there are many objects involved in the comment information, and the same expression in the comment information has different positions for different objects. Therefore, the current object-based method for sentimental praise and criticism analysis cannot be directly applied to stance analysis. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a method for constructing a stance analysis model based on the evaluation object camp. Aiming at the comment information of network social media, an object camp dictionary is constru...
