[0051] Please refer to figure 1 , which is a schematic flowchart of an embodiment of the matching viewpoint mining method of the present application. The subject of execution of the method includes, but is not limited to, the server, and may also be any device capable of implementing the method. In this embodiment, the method may include the following steps:

[0052] Step S101: Acquiring the first text and the second text including matching viewpoints.

[0053] The first text and the second text constitute a debate text, and the method can perform matching opinion mining on a longer debate text.

[0054] In an example, the method is applied in the field of debate, the first text may be a positive debate text, and the second text may be a negative debate text. By means of the method, pros and cons can be mined from pros and cons debate texts.

[0055] In another example, the method is applied in the field of intelligent justice, the first text may be a text provided by the ...

Abstract

The invention discloses a matching viewpoint mining method and device. The method comprises the steps that a first text and a second text are obtained, and the first text and the second text comprise sentences; determining shared sentence vectors of the sentences according to word vectors in the sentences through a shared sentence vector determination module in the matched viewpoint recognition model; judging whether the sentence is an argument or not according to the shared sentence vector by matching an argument classifier in the viewpoint recognition model; and judging whether the first text sentence and the second text sentence are matched viewpoints or not according to the shared sentence vector through a matched viewpoint classifier in the matched viewpoint recognition model. By adopting the processing mode, the multitask training model is combined with two sub-tasks, namely a debate mining sub-task and a debate pairing sub-task, so that better shared sentence representation is learned, and then one-to-one corresponding matching viewpoints in a debate text are mined; therefore, the matching viewpoint mining accuracy can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of debate mining, and specifically relates to a matching viewpoint mining method and device, a matching viewpoint recognition model building method and device, a debate robot system, and electronic equipment. Background technique [0002] Argumentation mining (Argumentation Mining) is an important task in computational argumentation. Its main goal is to automatically extract arguments (Argument) from texts in order to provide structured data for argumentative and inference engine computational models. Currently, most of the existing argumentative mining tasks perform argumentative mining from a single passage, such as extracting arguments from legal documents, dissertations, etc. Furthermore, existing multi-text-based argumentative mining is limited to online discussions or debates in forums, where arguments are extracted from a large number of articles in online forums. [0003] In the process of...
