The National Taiwan University Library has built a digital library of historical documents about Taiwan. The content is unique in that it covers about 80% of all primary Chinese historical materials about Taiwan before 1895, and that they are all available in searchable full text, in addition to metadata. To make these materials more accessible to the research community, we have developed, in a...

regarding the literary historical debates, one of the main concerns of modern historiography is the way of representing the concept of reality within the framework of a coherent narrative, a reality that is only achievable through the process of narrative that is supposed to be constructive and ordering. therefore, in order to examine this ordering process of narrative in james joyce's novel, a...

Historical document collections present unique challenges for information retrieval. In particular, the absence of consistent orthographic conventions in historical text presents difficulties for conventional search architectures which typically rely on a static inverted index keyed by orthographic form. Additional steps must therefore be taken in order to improve recall, in particular for sing...

In this work, a multi-scale binarization framework is introduced, which can be used along with any adaptive threshold-based binarization method. This framework is able to improve the binarization results and to restore weak connections and strokes, especially in the case of degraded historical documents. This is achieved thanks to localized nature of the framework on the spatial domain. The fra...

This paper describes an on-going project of transcribing and annotating digitized manuscripts of medieval Spanish with paleographic and lexical information. We link lexical units from the manuscripts with the Multilingual Central Repository (MCR), making terms retrievable by any of the languages that integrate MCR. The goal of the project is twofold: creating a paleographic knowledge base from ...

This paper presents a textline detection method for degraded historical documents. Our method follows a conventional two-step procedure that the binarization is first performed and then the textlines are extracted from the binary image. In order to address the challenges in historical documents such as document degradation, structure noise, and skews, we develop new methods for the binarization...

In this study, we propose a newmethod for retrieving and recognizing words in historical documents. We represent word images with a set of line segments. Then we provide a criterion for word matchin...

Spatial selections are a ubiquitous concept in visualization. By localizing particular features, they can be analysed and compared in different views. However, the semantics of such selections often depend on specific parameter settings and it can be difficult to reconstruct them without additional information. In this paper, we present the concept of contextual snapshots as an effective means ...
