Historical Documents on the 1854 Iga-Ueno Earthquake

Historical reflections on the sesquicentennial of the founding of the Boston Prison Discipline Society (1825-1854).

Supervised Text Region Identification on Historical Documents

We present multi-column text region identification support for Ocular, the unsupervised historical printed document transcription project of Berg-Kirkpatrick et. al (2013). We use structured prediction with rich features defined on the input document and incorporate a transition model based on prior document layout assumptions. Our model is trained using a structured-SVM objective on a randomly...

Historical Documents Modernization

Historical documents are mostly accessible to scholars specialized in the period in which the document originated. In order to increase their accessibility to a broader audience and help in the preservation of the cultural heritage, we propose a method to modernized these documents. This method is based in statistical machine translation, and aims at translating historical documents into a mode...

Unsupervised Transcription of Historical Documents

We present a generative probabilistic model, inspired by historical printing processes, for transcribing images of documents from the printing press era. By jointly modeling the text of the document and the noisy (but regular) process of rendering glyphs, our unsupervised system is able to decipher font structure and more accurately transcribe images into text. Overall, our system substantially...

Mining dates from historical documents

The essential quality of information in a digital library is accessibility. Full text search is not enough for some collections, more can be done. Historical collections, for example, contain dates, and it would be useful to historians to be able to search by them. However, these dates occur anywhere within the text of historical documents, and to be searched they must be extracted from the doc...
