Historical documents contain facts that family history enthusiasts are interested in extracting. In addition to fact extraction, organizing these facts into disambiguated entity records is also of interest. This paper shows how facts from an excerpt of a page in an OCRed book can be gathered automatically with some expert knowledge.

Immigration to the UK has risen in the past 10 years and has had a measurable effect on the supply of different types of labour. But, existing studies of the impact of immigration on the wages of native-born workers in the UK (e.g. Dustmann, Fabbri and Preston, 2005) have failed to find any significant effect. This is something of a puzzle since Card and Lemieux, (2001) have shown that changes ...

Abstract: Binarization is performed in the preprocessing stage for document inspection. Binarization of degraded document images improve the result from poor quality of the paper, the printing process, ink blot and fading document and remove noise from examine. In recent years, libraries have begun to digitize historical document that are of interest to a wide range of people, with the goal of ...

Simplifying and structuring qualitatively complex knowledge, quantifying it in a certain way to make it reusable and easily accessible are all aspects that are not new to historians. Computer science is currently approaching a solution to some of these problems, or at least making it easier to work with historical data. In this paper, we propose a historical knowledge representation model takin...

What are the possibilities of Semantic Web technologies for organizations which traditionally have lots of structured data, such as metadata, available? A library is such a particular organization. We mapped a digital library’s descriptive (bibliographic) metadata for a large historical document collection encoded in MARC21 to a historical ontology using an out-of-the-box ontology, existing top...

Many obsolete coordinate systems used in the past have fallen into disuse. However, the contents of historical documents still refer to these obsolete coordinates and thus translation systems are important in locating historical events. We present a specialized Linked Open Data API constructed to translate obsolete British Trench Map coordinates from the Great War into modern WGS84 coordinates....

1. A synthetic 3-([14C]valine)-labelled tetradecapeptide renin substrate was used to measure renin concentration. Renin liberated "4C-labelled angiotensin I, which was separated from the labelled substrate by paper chromatography. The conversion ofsubstrate into angiotensin I was quantitated by liquid-scintillation counting of radioactivity. 2. The rate of conversion of the substrate into angio...

We propose a generalization of higher-dimensional automata, partial HDA. Unlike HDA, and also extending event structures and Petri nets, partial HDA can model phenomena such as priorities or the disabling of an event by another event. Using open maps and unfoldings, we introduce a natural notion of (higher-dimensional) bisimilarity for partial HDA and relate it to history-preserving bisimilarit...

Graph-based representations are experiencing a growing usage in visual recognition and retrieval due to their representational power in front of classical appearance-based representations in terms of feature vectors. Retrieving a query graph from a large dataset of graphs has the drawback of the high computational complexity required to compare the query and the target graphs. The most importan...

Newspaper archives are some of the richest historical document collections. Their study is, however, very tedious: one needs to physically visit the archives, search through reams of old, very fragile paper, and manually assemble cross-references. We present Shax, a visual newspaper-archive exploration tool that takes large, historical archives as an input and allows interested parties to brows...
