Problems solved by technology

However, not all corpus data can find the content of web pages containing anchor text data on the Internet, so the data sources of this scheme are very limited
Therefore, if the word segmentation training data is obtained completely in this way, the obtained word segmentation training data will have obvious data sparse problems

Abstract

The embodiment of the invention discloses a construction method and device of the word segmentation training data. The construction method of the word segmentation training data comprises the following steps: acquiring an inquiry sentence of a user in an inquiry session of the user and the webpage title of a webpage finally clicked by the user; comparing the inquiry sentence with the webpage title to obtain a public character string between the inquiry sentence and the webpage title; performing word segmentation on the inquiry sentence and the webpage title according to the obtained public character string. By adopting the construction method and device of word segmentation training data provided by the embodiment of the invention, the data source of the word segmentation training data is enriched, and the problem of data sparseness of the word segmentation training data is solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of natural language processing, and in particular to a method and device for constructing word segmentation training data. Background technique [0002] Most word segmentation technologies require background corpus. Therefore, the annotation quality of the corpus in the corpus determines the quality of the final word segmentation results. At present, the labeling of corpus data in most corpora is done manually. The manual labeling of corpus data has high requirements on the professional quality of the labelers, and the manual labeling process is time-consuming and laborious, resulting in low efficiency of word segmentation for corpus data. [0003] There is a solution to improve word segmentation efficiency of corpus data, which is to use the anchor text on the webpage as a reference to perform word segmentation on corpus data. For example, the text "John Venn was a 19th-century Brit...
