Abstract :
We proposed a method for recognizing matrices which contain abbreviation symbols, and a format for representing the structure of matrices, and reported experimental results in our paper (2002). The method consisted of 4 processes: detection of matrices, segmentation of elements, construction of networks and analysis of the matrix structure. In the paper, our work is described with a focus on the construction of networks and the analysis of the matrix structure. However, we concluded that improvements in the other two processes were very important for obtaining a high accuracy rate for recognition. In this paper, we describe the two improved processes, the detection of matrices and the segmentation of elements, and we report the experimental results.
