[0050] refer to figure 2 , figure 2 For the first embodiment of the text filtering method of the present application, the method includes:

[0051] Step S110: Obtain text fluency based on the language model.

[0052] The calculation of text fluency in this application uses a language model combined with perplexity as a fluency evaluation standard. The language model can be an N-gram language model, a topic model, a neural network model, and GPT (Generative Pre-Training), BERT (Bidirectional Encoder Representations from Transformers), XLnet and other pre-trained language models, this application uses the BERT model as an example for detailed process description, but the language model in this application is not limited to the above-mentioned language model, and can be other language models.

[0053] The goal of the BERT model is to use large-scale unlabeled corpus training to obtain text semantic representations containing rich semantic information, and then fine-tune the t...

Abstract

The invention discloses a text filtering method and device and a computer storage medium. The method comprises the following steps: obtaining text fluency based on a language model; obtaining an effective word rate based on an effective word dictionary constructed in a user-defined manner; when the text fluency meets a first preset threshold value and the effective word rate meets a second preset threshold value, executing a filtering operation on the text. According to the method, the problems of time and labor consumption, low efficiency, high cost and low quality of manual text screening and filtering are solved, and the semantic-level and character-level text screening quality in the corpus is improved, so the training model and service quality are improved, and the calculation overhead is reduced.

Description

technical field [0001] The invention relates to the field of natural language processing, in particular to a text filtering method, device and computer storage medium. Background technique [0002] With the rapid development of artificial intelligence technology, the importance of artificial intelligence security has become increasingly prominent, and in artificial intelligence technology, natural language processing technology has been widely used. Natural language processing technology uses text as the processing target to provide assistance for production and life. However, under the background of the big data era and the untrusted environment of multi-source big data, low-quality text data poses a great threat to the training and testing of natural language processing models. In order to deal with the problem of low-quality text, various text filtering schemes emerge in endlessly. [0003] At present, text filtering methods are mostly based on filtering rules formulate...
