Design of Exercise Grading System Based on Text Similarity Computing

Text similarity, as an important basis for scoring subjective items in the examination, directly determines examination results of candidates and work efficiency teachers. Therefore, this paper first introduces theoretical text similarity computing compares different calculation methods. Then, text-similarity algorithm is designed, where by conceptualizing terms, methods based on corpus knowledge base are combined. according to model automatic grading system exercises including design technical architecture, functional modules, realization process comprehensive grading. Among them, module core key The systematic test show that problem designed has little difference from manual marking can achieve good results.
