Problems solved by technology

[0003] For documents in different fields, due to their unique language characteristics in this field, no matter whether they use dictionaries and word frequency to calculate text similarity or use pre-trained similarity calculation models to determine text similarity, they will all be different. The calculation of text similarity is only calculated at the level of words, and the accuracy is poor

Embodiment Construction

[0039] As mentioned in the background art, in the prior art, whether the method of calculating text similarity by using dictionary and word frequency or the method of determining text similarity by pre-trained similarity calculation model, for documents in different fields, it will cause The calculation of text similarity is only performed at the word level, and the accuracy is poor.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] figure 1 It is a flowchart of a method for calculating the similarity of judgment documents in an embodiment of the present invention.

[0042] figure 1 The method for calculating the similarity of judgment documents may include the following steps:

[0043] Step S101: Obtain at least two judgment documents.

[0044] Step S102: Extract ...

Abstract

The invention provides a judgement document similarity calculation method, a judgement document similarity search device, and computer equipment. The judgement document similarity calculation method comprises the following steps of: obtaining at least two judgement documents; extracting judgement keywords of one or more defendants in each judgement document; and determining the similarity between corresponding judgement documents according to the similarity between the judgement keywords corresponding to the defendants in different judgement documents. According to the judgement document similarity calculation method, the judgement document similarity calculation correctness is improved.

Description

Technical field [0001] The present invention relates to the technical field of data processing, in particular to a method for calculating the similarity of judgment documents, a searching device and computer equipment. Background technique [0002] In the prior art, a method for calculating text similarity is to segment two long texts respectively based on a dictionary, and calculate the word frequency of each segmented word obtained by segmenting the words in each text, and then determine the two texts according to the dictionary The similarity between the word segmentation in, and then calculate the overall similarity of the two texts according to the obtained similarity and word frequency; another way to calculate the text similarity is to train a text similarity calculation model through machine learning in advance , And then determine the similarity between texts based on the model. [0003] For documents in different fields, due to their unique language characteristics in th...
