Surveying Applicability of Energy Recovery Technology for Waste Treatment

Aduramo Lasode (University of Minnesota)

This project focuses on data collection and analysis regarding six prime movers: gas turbines, steam turbines, microturbines, reciprocating internal combustion engines, solid oxide fuel cells and Stirling engines. Prime movers are part of an energy recovery effort that reuses heat and power generated from combustible gases produced in waste treatment. In order to aid renewable energy, prime mover technology needs to be optimally implemented within the waste treatment industry. The project will address the difficulty of making optimal choices for waste treatment applications and aid a growing distributed waste treatment industry. First, data collection from the HathiTrust Digital Library will extract values that influence use of these prime movers, mainly power output, efficiency, capital cost, and fuel composition. Then, data analysis will be performed using methodology from a preliminary study evaluating efficiency-based applicability for five of the six aforementioned prime movers. The major output of this project is a dataset containing power, efficiency, cost and fuel-related information for six prime movers, with a goal to publish data and resulting analysis in addition to being incorporated into the researcher’s dissertation. The project outcomes will impact relevant fields in sustainability, combustion, and energy policy through a practical decision guide for choosing prime movers in waste treatment facilities, as well as by highlighting the need for innovation, with a special focus on prime mover applicability in the growing distributed waste treatment industry.

Detecting and Transcribing Arabographic Texts

David Smith (Northeastern University), Matthew Thomas Miller (University of Maryland), Maxim Romanov (University of Vienna), and Sarah Bowen Savant (Aga Khan University, London)

While not predominant, significant material is available in Arabographic languages, such as Arabic and Persian, in HathiTrust. Transcription accuracy in these languages is lower, however, than in Latin-script languages. Perhaps due to the use of synthetic data from digital fonts to train optical character recognition (OCR) systems, OCR models perform poorly on the large numbers of Arabographic printed books set in historical fonts or lithographed from manuscripts. When Arabic or Persian text is embedded in books in other languages, such as English, the non-Latin text is often transcribed as if it were English in a very strange font, resulting in near-zero accuracy. This project will work toward solutions to both problems. First, the research team will improve baseline Arabic and Persian OCR by finding editions of canonical texts in the HathiTrust collection and aligning images of those editions with existing digital transcriptions. Then they will use this aligned data to train new generalized models for a wide variety of typefaces and lithographed book hands. Second, the researchers will build classification models to detect pages with embedded Arabic and Persian, using textual features of the matrix language alone using the HTRC Extracted Features dataset. They will align existing digital transcripts of texts for 30 works in Arabic and 24 works in Persian in HathiTrust to run their baseline OCR system, and then extract page images of lines matched to spans of text in the digital editions.

Tracing the shifting rhetoric of ethnoracial difference in federal responses to education, 1958-2018

Andrés Castro Samayoa (Boston College)

This project leverages HathiTrust’s U.S. Federal Documents Collection to investigate how materials produced by the U.S. federal government document shifts in terminologies of ethnoracial difference. The project will focus on the documents and materials published by the Department of Education (formerly United States Department of Health, Education, and Welfare) and related congressional documents from hearings in specialized subcommittees from 1958 until the present. It will explore how the rhetorics of ethnoracial difference overlapped with the growing allocation of federal resources to postsecondary institutions, particularly Minority Serving Institutions, in the latter half of the 20th century. The start of the National Defense Education Act in 1958 was a watershed moment that signaled the greater engagement of the federal government in higher education.The subsequent passing of the Higher Education Act in 1965, alongside amendments through the 1990s and 2000s, allocated specific federal appropriations to support colleges and universities, including Historically Black Colleges & Universities, Tribal Colleges & Universities, Hispanic Serving Institutions, and Asian American & Native American Pacific Islander Serving Institutions. The project contributes to current work focusing on the history of federal responses to higher education in the United States, and the growing visibility of Minority Serving Institutions as a valuable sector of the postsecondary sector in the United States’ higher education.

Building large-scale collections of genre fiction

Laure Thompson and David Mimno (Cornell University)

This project will develop methods for automatically constructing large-scale collections of genre fiction from HathiTrust. Even, and especially, in digital libraries as large as HathiTrust, it can prove challenging to understand whether the library contains suitable representations of a chosen genre. The researchers plan to focus on collections of speculative fiction novels as a case study, but they intend their solutions to be generalizable. They will identify robust methods for correlating author-title pairs to matching volume sets in HathiTrust. Using these methods in conjunction with lists of novels that were curated by hand, they will build their collections and investigate which works are (over)represented and which are missing. They expect their project will enable scholars to better understand the suitability of studying genre fiction through HathiTrust and highlight underserved author and genre groups. Moreover, the project will result in collections of genre fiction which can be readily reused and reorganized for different lines of humanistic inquiry.

Mapping scientific names to the HathiTrust Digital Library 

Matthew J. Yoder and Dmitry Mozzherin (University of Illinois)

 This project will create an index of all the scientific names of the Earth’s species found within the HathiTrust corpus. The index, which will likely measure in the hundreds of millions to billions of entries, will consist of a simple link between the scientific name and the volume and page location of that name within HathiTrust. The index will assist in identifying volumes that may be medically relevant, for example by identifying all of the volumes containing the scientific name for the mosquito that carries illnesses such as Zika virus (‘​Aedes aegypti’). The index will also allow volumes to be grouped into clusters based on which scientific names they contain to show which taxon (e.g. “mammals”) are most common. This team of researchers has completed similar work across the data of the Biodiversity Heritage Library. Their ACS project will allow them to do cross-corpora comparisons.

Supporting The Conglomerate Era Project

Dan Sinykin (Emory University)

This project furthers the researcher’s investigation into how the conglomeration of the publishing industry changed literature. The results will be included the researcher’s in-progress book titled The Conglomerate Era: A Computational History of Literature in the Age of the Agent. The project explores a set of publisher-based corpora to see whether there are distinctions in what is published by large publishing houses versus independent presses. It will make use of predictive modeling to further the researcher’s existing work to build a computational model of genre that aids in identifying latent patterns in the publishers’ editorial practices.The project will utilize methods such as genre detection through unsupervised modeling; stylistic differentiation through text classification and supervised learning via logistic regressions; and social network analysis with metadata to determine latent literary connections, especially with regard to gender and race of the author.

Deriving Basic Illustration Metadata

Stephen Krewson (Yale University) 

This project aims at identifying all pictorial elements in educational texts from 1800-1850 to explore the interplay between progressive education and print media in the early nineteenth century. The resulting research will characterize the extent to which wood engravings and other reprographic materials were shared among educational publishers. The researcher will extract specific features from page images, such as illustration location, using advances in machine learning. The project intends to make use of the process developed to identify pictorial elements to motivate a new metadata field that describes the location and type of illustrations on the page. An ultimate goal of the project is to move toward “machine-read” texts where the data generated by classifiers and dimensionality reduction techniques are bundled as metadata with the corresponding volumes and made available to future research. (“Machine-read” is a term is borrowed from researcher Ben Schmidt.)

Semantic Phasor Embeddings

Molly Des Jardin, Scott Enderle, and Katie Rawson (University of Pennsylvania)

This project intends to explore a novel way of abstracting and representing textual data that could aid in new ways of discovering and deduplicating items in HathiTrust, detecting and analyzing genre, or analyzing narrative analogies. The project team will investigate the utility of a certain kind of mathematical representation of text documents, called semantic phasor embeddings, that combine a mathematical structure called phasors with data from standard word embeddings (strings of numbers that represent an item). If successful, the vectors could represent documents with a tunable degree of granularity, which could provide an opportunity to share vectors representing copyright-protected without concerns about wholesale text reproduction. The vectors would also carry valuable information about the global ordinal structure of the volumes, so that the items could be queried, clustered, and visualized in a robust way that recognizes similarity not just in the content of the items, but also their structure.

Modeling the History of Book Design

David Bamman and Bjorn Hartmann (University of California, Berkeley)

This project will utilize the HTRC Data Capsule to conduct feature extraction on page images from 10,000 in-copyright books in the HathiTrust repository, extracting features such as page construction, line justification, leading between baselines, kerning between letter pairs/combinations, line density per page, characters per line, position of images, typeface (serif, sans-serif) and font size. Beyond the analysis and utility of the extracted feature set, this project also seeks to serve as a use case for engagement with HathiTrust/HTRC beyond books-as-strings-of-words analysis.

The Power of Place: Structure, Culture, and Continuities in U.S. Women’s Movements

Laura Nelson (Northeastern University)

Dr. Nelson’s project will study the women's movement in the United States from 1848-1975 in two cities, New York City and Chicago, using new advances in network analysis and computational text analysis to identify structural and cultural diversity. This approach is three-pronged: building a workset of writing by individuals and organizations within the movements in New York and Chicago, using network analysis to measure the structure of this movement, and conducting computational text analysis to measure the underlying culture and ideas within the movement, including lexical analyses to identify distinctive words and topic modeling to identify dominant themes.

A Computational History of the U.S. Novel, 1950-2000

Richard Jean So (McGill University)

Dr. So’s project seeks to write a new history of the American novel by examining a series of large textual datasets focused on the full cycle of the U.S. literary field from production to reception to canonization. The major goal is to identify the emergence of new patterns of language, style, discourse and themes in American novels as they appear at different moments in the cycle of literary production and reception, including publication via large publishing houses such as Random House, and book reviews in major U.S. periodicals. This will be achieved through using the HTRC Data Capsule environment to undertake text analysis of full texts, including using various methods in Machine Learning and Natural Language Processing, such as topic models, word embeddings, and specialized tools such as BookNLP, which allows for the extraction of grammatical dependencies and characters.

Measuring Literary Novelty

Laura McGrath, Devin Higgins, and Arend Hintze (Michigan State University)

This work draws on ongoing collaborative efforts to develop a method for applying genetic sequencing tools to the study of literature in order to identify and measure literary novelty, and address questions of literary history, canonicity, and prestige. Previous results have been suggestive of a prominent connection between the purely information-based novelty of the sequences of characters that comprise literary texts, and the experimental newness we associate with modernist literary texts. Leveraging the HTRC Data Capsule will offer the potential to apply this theory at scale for the first time, and potentially lead into new research into modernism and the literary history of the 20th century.

A Writer’s Workshop Workset with the Program Era Project (PEP)

Nicholas Kelly, Loren Glass, and Nikki White (University of Iowa)

The PEP team will compile a proof-of-concept workset with, at first, prominent individuals (faculty, staff, students) who were involved with the Iowa Writers’ Workshop (IWW), then produce “style cards” for each author’s works (by volume), based on stylometric data gathered through text analysis of the IWW workset within the HTRC Data Capsule. It is the goal of the project to also create a living workset that can be continually updated for scholars who wish to engage with IWW authors and their writing.

Signal and Noise and Pride and Prejudice: Toward an Information History of Romantic Fiction

Dallas Liddle (Augsburg College)

This project will test two hypotheses about information theory and information density as they relate to a digital humanities approach to studying Romantic-era British fiction. The concept of "information" used in mathematical information theory may help digital humanists evaluate the information density of textual forms. This project tests a theory that the popular and critical success of the novel in British print culture after 1815 may be related to increased information density and sophistication of information encoding in those years, especially via innovations introduced by Jane Austen and Walter Scott.
