This paper describes the Gamera framework for building custom document recognition systems. This open-source system is designed to support the testand-refine development cycle: an important style for developing recognition systems that work with difficult historical documents, since the solutions are often non-obvious. This paper explains the overall architecture of the system, in addition to d...

The BVC section of the impact-es diachronic corpus of historical Spanish compiles 86 books —containing approximately 2 million words. About 27% of the words —providing a representative coverage of the most frequent word forms— have been annotated with their lemma, part of speech, and modern equivalent following the Text Encoding Initiative guidelines. We describe how this type of annotation can...

The standard business model in the sponsored search marketplace is to sell click-throughs to the advertisers. This involves running an auction that allocates advertisement opportunities based on the value the advertiser is willing to pay per click, times the click-through rate of the advertiser. The click-through rate of an advertiser is the probability that if their ad is shown, it would be cl...

In this chapter, a binarization technique specifically designed for historical document images is presented. Existing binarization techniques focus either on finding an appropriate global threshold or adapting a local threshold for each area in order to remove smear, strains, uneven illumination etc. Here, a hybrid approach is presented that first applies a global thresholding technique and, th...

Providing useful and efficient semantic annotations is a major challenge for knowledge design of any body of text, especially historical documents. In this article, we propose Topic Modeling as an important first step to gather semantic information beyond the lexicon which can be added as annotations in the SHEBANQ. By laying out a case study, we discuss both noise and structure found in compar...

In this project, we aim to estimate the effect of different teaching strategies in a tutoring system on student learning and how that effect varies across different groups of students. More specifically, we want to shed light on whether choosing exercise problems adaptively based on prior student performance is more effective at teaching elementary school students about fractions than non-adapt...

In this paper, we report a databank development project in which structured textual data from historical documents are extracted to provide information access of higher data granularity. The availability of the databank opens up tremendous opportunities for research topics in government personnel systems that were limited by data acquisition difficulty in the past. The project demonstrates the ...

Industrial engineering was originally founded as a discipline that focused on the study and design of work. Yet, today the field has largely distanced itself from this early concern. This paper tracks the decline of work studies in industrial engineering and explores the question of why the discipline lost its concern for work and, ultimately, its ability to speak to the kinds of social and eco...

Gospels are one type of translated historical document. There are many versions of the same Gospel that have been translated from the original, or from another Gospel that has already been translated into a different language. Nowadays, it is difficult to determine the language of the original Gospel from where these Gospels were translated. In this paper we use a supervised machine learning te...
