Research on language expression query method based on XML

Abstract

Data is self-descriptive, extensible, and has both content and structure information. Documents are commonly found on web pages, business texts, digital libraries, etc., and the number of documents is increasing exponentially. In this paper, through the research of the language keyword query method based on XML, it can effectively reduce the query result set and improve the query accuracy. In the process of evaluation, we use the grading gauge and present it online to the raters based on the computer platform, which can not only standardize the grading process and ensure the reliability of the grading results to a great extent, but also provide personalized ability performance feedback for learners and teachers, so as to facilitate them to check the gaps and make up for the gaps, aiming to promote learning through evaluation.
