Content enhancement. We want to search the data in ways that we currently can't.Engage new audiences with BHL content outside of our own portal users.</p> <p>6</p> <p>Crowdsourcing Crowdsourcing is a way to tackle known tasks with limited staff when we don't have too many resources</p> <p>Why we are doing this? </p> <p>Whats the Purpose?</p> <p>When a book is first digitized, its pages are merely image files and the text cannot be searched. Optical character recognition software (OCR) converts these page images into machine encoded text that can be searched, but historic literature has many idiosyncrasies that inhibit accurate OCR. BHL wanted to harness the power of crowdsourcing and the fun of gaming to allow humans to help correct inaccurate OCR. The games present extracted words from BHL books that users type out, thus verifying the spelling. These submissions are used to correct the OCR in BHL. By presenting users with a high volume of words in rapid succession during each play-through, we can receive a large number of word corrections and achieve a significant level of OCR correction.8</p> <p>Illustrations discovery, tagging and descriptionIllustration discovery is the need,Illustration tagging is the task and Science Gossip is the site in the Zooniverse platform.</p> <p>Corpus, lots of valuable illustrations hidden, hard to identify specifically, discoverability.</p> <p>After initially running automatic algorithms for basic identification, that reduced the amount of pages to review, we used crowdsourcing to filter out the false positives and identify more specifically the type of illustration available</p> <p>9</p> <p>Science Gossip ZooniversePartner with a team in UK called ConSciCom (Constructing Scientific Communities) that analyses Citizen Science of the 19th Century and the 21st Century.ConSciCom provided the Subject Expertise, BHL provided the content (19th Century Periodicals) and Zooniverse provided the platform (and IT Support) in which users are asked to classify and describe natural history illustrations from 19thcentury periodicals found within the BHL.</p> <p>Step 1. Are there illustrations on the page?Step 2. Ask users to draw boundaries around an illustration in the pageStep 3. Classify it.Step 4. Mark species, inscriptions and contributorsStep 5. Talk! - A key piece to user engagement! Quality control. Frequent users turned into moderators. FAQ creators.</p> <p>AdvantagesDetails of Talk After seeing in action, giving heavy users a place to commune with other taggers. First time comments around BHL content from an audience that was mostly new to BHL.</p> <p>We had a labor-ready workforce in the Zooniverse platform was already formed, they had the critical mass community.</p> <p>Took a moderate quantity of our own resources and time to develop because of the possibility of leveraging the platform that already existed website up in a couple of months.</p> <p>Embedded quality control</p> <p>Experience in different fields by each of the stakeholders</p> <p>DisadvantagesChallenge of having to handle multiple verifications.</p> <p>Beanstalk and Smorball</p> <p>Smorballgame.orgBeanstalkgame.org</p> <p>The second is through two online games, called Beanstalk and Smorball, which BHL commissioned from Tiltfactor (http://www.tiltfactor.org/), based at Dartmouth College.</p> <p>Different audiences.</p> <p>14</p> <p>How does it work?</p> <p>15</p> <p>Best Serious Game Award at the Boston Festival of Indie Games 2015</p> <p>Thank youTrish Rose-SandlerPrincipal InvestigatorPurposeful Gaming and BHL</p> <p>Smorball and Beanstalk were designed as part of thePurposeful Gaming and BHL project, which explores how digital games can make scanned content more accessible and searchable for cultural institutions. </p> <p>Based at the Missouri Botanical Garden in St. Louis, Missouri, Purposeful Gaming and BHL was established in 2013 through anInstitute of Museum and Library Services (IMLS)grant and includes partners at Harvard University, Cornell University, and The New York Botanical Garden.</p>
