Early Art of the Far East Dikova Hathi Trust

Working with HathiTrust

As members of the HathiTrust community, George Washington University kinesthesia, students and staff may make use of the HathiTrust corpus of digitized books for research and educational computational investigation.  The full corpus tin be searched using the HathiTrust Digital Library (HTDL).  Many of the books are in the public domain and the full text readily available.  For books nevertheless in copyright, HTDL makes available only the volume'due south descriptive metadata (though there is a mode to work with materials in copyright, described below).  HTDL utilizes your GW NetID and password for access.  At the HTDL site, click the Login Push button and select The George Washington University.  (annotation the T)

 The HathiTrust Research Center (HTRC) supports researchers with computational analysis using the corpus.  HTRC requires you to create a divide but gratuitous business relationship.  At a basic level, you tin can create a workset of books in HDTL and import this into HTRC to run basic algorithms; at the advanced level, y'all tin can piece of work with HTRC to gain access to the entire HathiTrust corpus, including materials however in copyright to use in nonconsumptive enquiry** activities.

Scroll downwardly to read more about the following options:

1. Web-based Algorithms
2. Datasets for NonConsumptive Research**
3. Data Capsules for NonConsumptive Enquiry

** From the 2010 Authors Social club vs Google amended settlement understanding:  "Non-Consumptive Enquiry means research in which computational analysis is performed on ane or more Books, just not enquiry in which a researcher reads or displays substantial portions of a Book to sympathise the intellectual content presented within the Volume."  Non-consumptive analytics includes image analysis, text extraction, textual analysis and information extraction, linguistic analysis, automated translation, and indexing and search.  Read more than on Hathi-Trust's Not-Consumptive Utilise Research Policy.

Getting Started Guide

HTRC's documentation and FAQ to go yous started.

1.  Web-based Algorithms (Public Domain Books)

At a bones level, you tin can run scripts on small worksets of books you have gathered from the HathiTrust Digital Library, basically canned algorithms for quick analysis.

1. Open up HTDL and HTRC and login to both.
2. In HDTL, build a collection using the public domain volumes in HathiTrust Digital Library.  Upload your workset into HTRC.
3. In HTRC, employ the spider web-based algorithms.  Execute an algorithm.  This will prompt you to select a workset (your own, or a publically available workset).

Note:  This arroyo does Non include in-copyright works.

• HathiTrust Digital Library

This is the digital preservation repository and access platform.  It provides long-term preservation and access services for public domain and in-copyright content from a variety of sources, including Google, the Internet Archive, Microsoft, and in-business firm partner institution initiatives.

• HathiTrust Research Center (HTRC) Analytics

Supports large-scale computational analysis of works in the HathiTrust Digital Library to facilitate not-profit and educational enquiry.  Sign up for a free account.

2.  Research Datasets

HTRC releases research datasets to facilitate text analysis using the HathiTrust Digital Library.  While copyright-protected texts are not bachelor for download from HathiTrust, enquiry can still be performed on the basis of non-consumptive analysis of features extracted from full-text, for example, northward-grams from over xiii meg volumes in the HDTL to clarify in the computer environment of your option.

Extracted features include volume-level metadata, page-level metadata, part-of-spoken communication-tagged tokens, and token counts.

three.  Data Capsules

The HTRC Data Sheathing gives a researcher a secure, virtual computer for not-consumptive analytical access to the full OCR text of the works in the HathiTrust Digital Library.  Data capsules are restricted, particularly in limiting how and when products created past assay tools get out the capsule.  Data products leaving the capsule must undergo results review prior to release.  To become started with Data Capsule, cheque out the tutorial below.
