Abstract

The invention relates to a text segmentation method and device. The method includes the steps: segmenting an inputted text content to generate a segmented text; tagging the part-of-speech of each segmented word of the segmented text and feature words included in the segmented text according to the association relationship of a context in the text content; outputting the segmented text including part-of-speech tags and feature word tags. The feature words comprise at least one of new words and dialects. Segmentation recognition accuracy can be improved, and ambiguity of segmentation is eliminated.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a text word segmentation method and device. Background technique [0002] Chinese word segmentation occupies an important position in natural language processing, and is an important part of natural language task processing such as entity recognition, text classification, text clustering, keyword extraction, machine translation, and intelligent question answering. However, compared with only separators between words in English, due to the complexity of the Chinese language, Chinese word segmentation faces various difficulties. [0003] The traditional Chinese word segmentation technology adopts the mechanical word segmentation method, that is, uses a fixed lexicon and adopts the maximum matching algorithm to segment Chinese words. However, since the fixed lexicon cannot identify new words, the current method cannot effectively identify new words, uncommon words and dialect...
