Math Search for the Masses: Multimodal Search Interfaces and Appearance-Based Retrieval

We summarize math search engines and search interfaces produced by the Document and Pattern Recognition Lab in recent years, and in particular the min math search interface and the Tangent search engine. Source code for both systems are publicly available. "The Masses" refers to our emphasis on creating systems for mathematical non-experts, who may be looking to define unfamiliar notation, or browse documents based on the visual appearance of formulae rather than their mathematical semantics.Comment: Paper for Invited Talk at 2015 Conference on Intelligent Computer Mathematics (July, Washington DC

Digital archiving of manuscripts and other heritage items for conservation and information retrieval

Expression of cultural heritage looking from the informatics angle falls into text, images, video and sound categories. ICT can be used to conserve all these heritage items like; the text information consisting of palm leaf manuscripts, stone tablets, handwritten paper documents, old printed records, books, microfilms, fiche etc, images including paintings, drawings, photographs and the like, sound items which includes musical concerts, poetry recitations, chanting of mantras, talks of important persons etc, and video items like archival films historical importance. To retrieve required information from such a large mass of materials in different formats and to transmit them across space and time, there are several limitations. Digital technology allows hitherto unavailable facilities for durable storage and speedy and efficient transmission / retrieval of information contained in all the above formats. Hypertext and hypermedia features of digital media enable integrating text with graphics, sound, video and animation. This paper discusses the international and national efforts for digitizing heritage items, digital archiving solutions available, the possibilities of the media, and the need to follow standards prescribed by organizations like UNESCO to enable easy exchange and pooling of information and documents generated in digital archiving systems at national and international level. The need to develop language technology for local scripts for organizing and preserving our cultural heritage is also stressed

Yours ever (well, maybe): Studies and signposts in letter writing

Electronic mail and other digital communications technologies seemingly threaten to end the era of handwritten and typed letters, now affectionately seen as part of snail mail. In this essay, I analyze a group of popular and scholarly studies about letter writing-including examples of pundits critiquing the use of e-mail, etiquette manuals advising why the handwritten letter still possesses value, historians and literary scholars studying the role of letters in the past and what it tells us about our present attitudes about digital communications technologies, and futurists predicting how we will function as personal archivists maintaining every document including e-mail. These are useful guideposts for archivists, providing both a sense of the present and the past in the role, value and nature of letters and their successors. They also provide insights into how such documents should be studied, expanding our gaze beyond the particular letters, to the tools used to create them and the traditions dictating their form and function. We also can discern a role for archivists, both for contributing to the literature about documents and in using these studies and commentaries, suggesting not a new disciplinary realm but opportunities for new interdisciplinary work. Examining a documentary form makes us more sensitive to both the innovations and traditions as it shifts from the analog to the digital; we can learn not to be caught up in hysteria or nostalgia about one form over another and archivists can learn about what they might expect in their labors to document society and its institutions. At one time, paper was part of an innovative technology, with roles very similar to the Internet and e-mail today. It may be that the shifts are far less revolutionary than is often assumed. Reading such works also suggests, finally, that archivists ought to rethink how they view their own knowledge and how it is constructed and used. © 2010 Springer Science+Business Media B.V

Steganoscription : exploring techniques for privacy-preserving crowdsourced transcription of handwritten documents

textThe focus my research is the historical document format represented by the Central State Hospital (CSH) dataset, handwritten medical records. The specific problem innate to the CSH dataset in question is how to transcribe sensitive, cursive-handwritten documents via a manual vehicle- such as crowdsourcing. Manual methods are necessarily no matter the sophistication of the optical character recognition system used because of the inconsistencies within cursive script. To address this problem I've developed an application that enables users to transcribe sensitive, handwritten, document images while preserving the privacy of the context around the transcribed text via random word selection and visual manipulation of the displayed text. This is made possible through several algorithms that process documents from a top-down approach. These system operations detect and segment lines of text in images, reverse the slant common to cursive script, detect and segment words, and finally, manipulate word-images before they are displayed to users; combinations of color, noise, and geometric manipulations are currently supported and used randomly. This system, called Steganoscription, combines the concepts of steganography and transcription.Informatio

Working Papers as Federal Records: The Need for New Legislation to Preserve the History of National Policy

This article deals with policy records at the front end of their lives; that is, preserving them from destruction by federal agencies in the decades immediately after their creation. It does not deal with the destruction of archived documents by Archives officials themselves. It discusses only in passing the related question of how long a policy record should be sealed off from public inspection; the literature includes a variety of opinions on that subject. The author is content to leave to others the problem of just where to draw the balance between making historical documentation available soon enough so that it can offer relevant lessons to citizens, but not so soon as to discourage officials from putting their candid thoughts and recommendations on paper or disk, for fear of public exposure and pressure. He focuses, instead, on the preservation of governmental records, and particularly of drafts, comments, and other working papers. Of course the issues of preservation and access are intimately linked: if records are routinely destroyed as soon as they are no longer needed by their creators, public access-even much delayed public access-becomes altogether impossible
