Embodiment 1

[0142] as attached figure 1 Shown, the Chinese sentence semantic intelligent matching method based on multi-granularity fusion model of the present invention, the method is specifically as follows:

[0143] S1, build text matching knowledge base; figure 2 As shown, the details are as follows:

[0144] S101. Use a crawler to obtain original data: crawl the question set on the Internet public question-and-answer platform to obtain the original similar sentence knowledge base; or use the sentence matching data set published on the Internet as the original similar sentence knowledge base;

[0145] There are a large amount of question-and-answer data and recommendations for similar questions in public question-and-answer platforms on the Internet, which are open to the public. Therefore, according to the characteristics of the question answering platform, a corresponding crawler program can be designed to obtain a collection of text sentences with similar semantics, so as to bui...

Embodiment 2

[0270] as attached Figure 10 Shown, the Chinese sentence semantic intelligent matching device based on multi-granularity fusion model of the present invention, this device comprises,

[0271] The text matching knowledge base construction unit is used to use the crawler program to crawl the question set on the Internet public question and answer platform, or use the text matching data set published on the Internet as the original similar sentence knowledge base, and then preprocess the original similar sentence knowledge base , the main operation is to perform hyphenation processing and word segmentation processing on each sentence in the original similar sentence knowledge base, thereby constructing a text matching knowledge base for model training; the text matching knowledge base construction unit includes,

[0272] Crawl the original data sub-unit, which is used to crawl the question set on the Internet public question-and-answer platform, or use the text matching data set...

Embodiment 3

[0290] Based on the storage medium of Embodiment 1, there are a plurality of instructions stored therein, and the instructions are loaded by the processor to execute the steps of the Chinese sentence semantic intelligent matching method based on the multi-granularity fusion model of Embodiment 1.

Description

technical field [0001] The invention relates to the fields of artificial intelligence and natural language processing, in particular to a Chinese sentence semantic intelligent matching method and device based on a multi-granularity fusion model. Background technique [0002] Sentence semantic matching plays a key role in many natural language processing tasks, such as question answering (QA), natural language inference (NLI), machine translation (MT), etc. The key to sentence semantic matching is to calculate the matching degree between the semantics of a given sentence pair. Sentences can be segmented at different granularities, such as characters, words, and phrases. Currently, the commonly used text segmentation granularity is words, especially in the Chinese field. [0003] At present, most Chinese sentence semantic matching models are oriented to word granularity, while ignoring other segmentation granularities. These models cannot fully capture the semantic features...
