Embodiment 1

[0050] The following introduces Embodiment 1 of a word segmentation method based on a multi-level dictionary provided by the present application, see figure 1 , embodiment one includes:

[0051] S101. For the target sentence, generate a vector representation of each character, and generate feature representations of each character in at least two dictionaries;

[0052] Specifically, the above-mentioned process of generating the feature representations of each character in at least two dictionaries specifically includes: for each word, generating its feature representations in each dictionary, performing Splicing to obtain the feature representation of the word in at least two dictionaries.

[0053] The above at least two dictionaries may be dictionaries classified according to their fields, dictionaries classified according to their word-forming probabilities, or even dictionaries classified according to their respective fields and word-forming probabilities at the same time....

Abstract

The invention discloses a word segmentation method based on multistage dictionaries, and the method comprises the steps: employing at least two dictionaries to assist a word segmentation model in wordsegmentation, generating conventional vector representation and feature representation of a character in the at least two dictionaries during the representation of the character, and finally, determining a word forming label of the character according to the vector representation and the feature representation. According to the method, by distinguishing the status and importance of different words, the word segmentation performance of the whole scheme is improved, and the domain adaptability and the word segmentation accuracy are improved. In addition, the invention further provides a word segmentation device and equipment based on the multilevel dictionary and a readable storage medium, and the technical effect of the word segmentation device and equipment corresponds to the technical effect of the method.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a word segmentation method, device, device and readable storage medium based on a multi-level dictionary. Background technique [0002] Chinese word segmentation is a process of dividing an input sentence into word sequences. An additional dictionary is usually provided for the model to alleviate the problem of insufficient training data for manual annotation. However, the current word segmentation schemes all use single-level dictionaries, ignoring the problem that different words in the dictionary have different word-forming probabilities, and also ignoring the problem that the same string becomes a word in one field but not in another field, resulting in The word segmentation effect of the word segmentation model is poor. [0003] The word segmentation method based on a single-level dictionary also has the problem of little influence on the actual word segmentati...
