Poor quality documents are obtained in various situations such as historical document collections, legal archives, security investigations, and documents found in clandestine locations. Such documents are often scanned for automated analysis, further processing, and archiving. Due to the nature of such documents, degraded document images are often hard to read, have low contrast, and are corrup...
This paper reports on experiments to improve the Optical Character Recognition (ocr) quality of historical text as a preliminary step in text mining. We analyse the quality of ocred text compared to a gold standard and show how it can be improved by performing two automatic correction steps. We also demonstrate the impact this can have on named entity recognition in a preliminary extrinsic eval...
The use of metaphor in popular science is widespread to aid readers’ conceptions of the scientific concepts under discussion. Almost all research in this area has been done by careful close reading of the text(s) in question, but this article describes—for the first time—a digital ‘distant reading’ analysis of popular science, using a system created by a team from Glasgow and Lancaster. This te...
1 VaR (Value at Risk) estimates are currently based on two main techniques, the variance-covariance approach or simulation. Statistical and computational problems affect the reliability of these techniques. We illustrate a new technique, filtered historical simulation, that is designed to remedy some of the shortcomings of the simulation approach. We compare the estimates it produces with tradi...
Palm leaf manuscripts were one of the earliest forms of written media and were used in Southeast Asia to store early written knowledge about subjects such as medicine, Buddhist doctrine and astrology. Therefore, historical handwritten palm leaf manuscripts are important for people who like to learn about historical documents, because we can learn more experience from them. This paper presents a...
The Great Parchment Book of the Honourable the Irish Society is a major surviving historical record of the estates of the county of Londonderry (in modern day Northern Ireland). It contains key data about landholding and population in the Irish province of Ulster and the city of Londonderry and its environs in the mid-17th century, at a time of social, religious, and political upheaval. Compile...
Static ontologies cannot capture the relevant contextual knowledge required for search and retrieval of historical documents because the entities in the world and the relations among them change over time. This demands that information represented in the ontology is temporally contextualized and that relations among entities that are relevant during different temporal intervals are available to...
1. Introduction Since libraries have collection of documents across age and culture, and even language, the libraries are inherently multi-age, multi-cultural, and multilingual. In the digital age, more and more historical documents are being digitized to preserve contents written in deteriorating papers. Library, etc.). It means that more and more old text contents will be accessible on the in...
We synthesized high-resolution precisely-dated stalagmite records and historical document records from north central China to reconstruct a decadal resolution precipitation record during the last 1800 years (190–1980 AD). The synthesized precipitation record shows coincident variations and significant positive correlations with the temperature reconstructions on centennialto multidecadal-scale,...
This paper describes HICAP (Hierarchical Interactive Case-based Architecture for Planning), a general purpose planning architecture that we have developed and applied to assist military commanders and their staa with planning NEOs (Noncom-batant Evacuation Operations). HICAP integrates a hierarchical task editor, HTE, with a conversational case-based planning tool, NaCoDAE/HTN. In this applicat...
