Research Abstract	We have developed an assisting application for analytical transcription of historical documents based on full-text search technique for image-scanned documents that does not recognize individual characters. The proposed method works independently of differences in language and font because it uses a new pseudo-coding scheme based on the statistical features of character shapes. In this project, we have developed an assisting application for historical document and back-end search server as a service, relevance feedback method with HMM and font robust pseudo-coding method. The system support transcribers of cursive manuscripts and accelerate the analysis of historical materials.
