This study compared two language models for Chinese character recognition. A bigram statistics model significantly improved recognition accuracy by 10%, outperforming a lexical analytic model.

Area of Science:

  • Natural Language Processing
  • Computer Vision
  • Statistical Modeling

Background:

  • Chinese character recognition systems often face accuracy challenges.
  • Statistical language models are crucial for improving recognition performance.
  • Lexical analytic models provide a baseline for evaluating language model enhancements.

Purpose of the Study:

  • To evaluate the effectiveness of two statistical language models in enhancing Chinese character recognition accuracy.
  • To compare a bigram statistics of word-classes model against a lexical analytic baseline model.
  • To quantify the recognition rate improvement offered by each language model.

Main Methods:

  • Investigated a lexical analytic language model using maximum matching and word binding forces for segmentation.

  • Developed and tested a bigram statistics of word-classes language model.
  • Compared the performance of both models on a Chinese character image recognition task.

    • Main Results:

    • The baseline lexical analytic language model improved recognition rates by an average of 7%.
    • The bigram statistics of word-classes model achieved a higher average improvement of 10%.
    • The bigram model demonstrated superior performance in enhancing Chinese character recognition accuracy.

    Conclusions:

    • Statistical language models significantly boost the accuracy of Chinese character recognizers.
    • The bigram statistics of word-classes model offers a more effective approach compared to lexical analytic models.
    • Further research into advanced language modeling techniques can lead to more robust character recognition systems.
