YUMA Map Annotation Prototype | Features & Goals

4

Tile-based viewing based on OpenLayers (for now) and MagickTiler1

Free-text annotation & semantic tagging Geographical features in the annotated area via Geonames Named entities mentioned in the annotation (places, persons, epochs,...)

via DBpedia Spotlight Tools for shape drawing and (basic) geo-referencing creation Place search, map overlay, shape export to KML RSS feeds on maps, annotations and users Designed for integration into a host portal Currently in prototype stage (and with experimental features – beware!) Open Source! http://github.com/yuma-annotation

Linked Data | Some Basics and Some Benefits

6EuropeanaConnect is coordinated by the Austrian National Library Co-funded by the European Community Programme eContentplus

Basics1

URIs for as names for things HTTP URIs so we can get information about those things

http://dbpedia.org/resource/Gibraltarhttp://sws.geonames.org/2411585/http://dme.ait.ac.at/yuma-server/api/annotation/39

(Typed) Links to other URIs so we can discover more things Many relevant datasets out there already!

Benefits (for map search) Multilingual & synonym search Spatial metadata & geographical search – control points as by-products

of annotation?

Towards Evaluating YUMA | The COMPASS Experiment

7EuropeanaConnect is coordinated by the Austrian National Library Co-funded by the European Community Programme eContentplus

Building Ground Truth 6.306 maps from the Library of Congress (batch converted to Zoomify) Original map metadata 130.935 (anonymous) user search queries Custom Web application for collecting relevance judgements First stage: corpus of 400 sample queries

Preliminary Results Users invited from MapHist and IFLA DIGLIB, INETBIB mailing lists 75 participants, 12+ countries, 1.800+ judgements (approx. 45% of target)

Next Steps COMPASS Social features Integration with YUMA Dissemination!

Next Steps YUMA User Interface and Usability Standards! OAC1 and OGC Geo-referencing by (approximate) projections in addition to control points?
