Project Description:


Chinese document recognition technology has achieved tremendous advance in recent years, however, it has not been solved yet for the documents of free handwriting or complicated background, where the recognition performance is not good enough for the industrial application, and is far away from human recognition. One issue of the current recognition methods is that it does not utilize the context information sufficiently. Meanwhile, there is rich context knowledge on the internet. To overcome this issue, it is a good way to integrate internet texts into the recognition system, however, this has not received enough attention yet. In this project, we will investigate the theory and key techniques for the integration of internet texts in the recognition system by internet search, and propose effective methods. The main research contents and innovations are as follows: (1) propose the internet text search method in the document recognition framework; (2) propose the document recognition method based on the strong linguistic context; (3) propose the unsupervised language model adaptation of both local and global contexts from Internet texts; (4) propose the dynamic combination of multiple context models based on the weekly supervised method. The proposed methods will improve the performance of document recognition, and promote the development of document recognition technologies in the industrial application, meanwhile, get academic value.
