| Research Abstract |
In this research project, we studied the following four research topics : (1) Structuring the knowledge of Historical Document Understanding, (2) Study of the Historical Chara cter Recognition using our Historical Character OCR dictionary, (3) Developing a Dictionary for Historical Character Recognition, and (4) Developing a proto-type system of a computer ized Historical Character Dictionary (1) We developed a Historical Corpus Database analyzing many loan contracts consists of 1, 300 documents and 243, 000 characters. The common and frequent expressions are extracted from the documents. By using the data, we developed a proto-type of Historical Document Analysis Supporting System using n-gram method. Through an usability test, efficiency of the interface is confirmed statistically. (2) We developed some Historical Character Recognition methods using neural network. (3) Besides the database described in (1), we made another Historical Character Database of "Kuzushi-ji Kaidoku Jiten" published from Tokyoudo Syoten, which is one of the standard dictionary. The dictionary includes 25, 000 characters. (4) We have done some basic studies and have made a proto-type system of portable electrical dictionary, which could be searched by pronunciation, shape, and stroke order.
