Introduction
• Location-based services (LBS) made geographically relevant info more accessible & desired
• Current ways to georeference are insufficient
• Online, crowdsourcing offers potential solution
Terminology
Geographic Info Retrieval
Importance of Topic
• People value geographically relevant information
• Long history of media used to deliver geo. relevance
• LBS have increased demand
• Much info in libraries not sufficiently georeferenced

In a survey I did, 86% of respondents reported using their device to access at least one place-related function in the past month. The results are dated now, so I expect these rates to be higher. At the high end, 84% reported finding proximal businesses or services, reading local news (74%), finding nearby sites (67%), and reading information about their location (66%).
Social Georeferencing
• Users create information for georeferencing, via
o geotagging
o plotting on map
• Helps with toponym problems
• Collaborative and social
• Scalable
Examples…
• Asked public to georeference maps
• Used online tool (below) developed by Klokan (klokantech.com/georeferencer)
• In 7 weeks, 2700 maps completed
• More details:www.bl.uk/maps
British Library
• Collaborative project with libraries & museums across Ontario
• Assisted in digitizing and online cataloguing of local history collections
• Public contributed objects and comments on location & details of existing online items
• More info:http://ourontario.ca/
OurOntario
• Easy to use and familiar online tool to georeference location of photos via plotting on map
• Flickr also enables geotagging, i.e. folksonomy tags
• Geotags may better capture place-name info seekingbehaviour of people
• Visit map:flickr.com/photos/glenfarrelly/map
Flickr Map
• LibraryThing is example of easy-to-use, social toolpeople use to describe, tag, and share info
• Projects have successfully combined LibraryThing’s user-generated content with library catalogues
• Model of way to combine social georeferencing with library catalogues
• librarything.com
LibraryThing
Caveats
• Quality and accuracy of public’s work
• Malicious hijacking
• Exploitation of free labour
• Creating and managing an online, collaborative system is time-consuming
• Maintaining public (and internal) interest in project
Encouraging Participation• Offer incentives and prizes
• Reward “super users”
• Give credit for contributions
• Promote with social media
• Engaging user experience (incl. gamification)
