Abstract

Die British Library hat über eine Million eingescannter Bilder im Web veröffentlicht. Die gemeinfreien, also frei verwendbaren Bilder, die über die Flickr-Seite der britischen Nationalbibliothek erhältlich sind, stammen aus Büchern des 17., 18. und 19. Jahrhundert, wie aus einer Mitteilung hervorgeht. Sie wurden von Microsoft aus 65.000 Büchern digitalisiert. Der Softwarekonzern und die British Library hatten vor acht Jahren eine Zusammenarbeit vereinbart. Die Inhalte von 100.000 Büchern sollten zunächst über Microsofts Buchsuchprojekt recherchierbar sein. Alle Abbildungen sind mit Herkunftsangaben und dem Erscheinungsjahr versehen. Im nächsten Schritt plant die British Library ein Crowdsourcing-Projekt, um die Bilder automatisch inhaltlich zu klassifizieren. Die Daten zu den Bildern hat die British Library auf Github bereitgestellt. Der Code soll unter eine offene Lizenz gestellt werden.

Abstract

To enable and guide effective metadata creation it is essential to understand the structure and patterns of the activities of the community around the photographs, resources used, and scale and quality of the socially created metadata relative to the metadata and knowledge already encoded in existing knowledge organization systems. This article presents an analysis of Flickr member discussions around the photographs of the Library of Congress photostream in Flickr. The article also reports on an analysis of the intrinsic and relational quality of the photostream tags relative to two knowledge organization systems: the Thesaurus for Graphic Materials (TGM) and the Library of Congress Subject Headings (LCSH). Thirty seven percent of the original tag set and 15.3% of the preprocessed set (after the removal of tags with fewer than three characters and URLs) were invalid or misspelled terms. Nouns, named entity terms, and complex terms constituted approximately 77% of the preprocessed set. More than a half of the photostream tags were not found in the TGM and LCSH, and more than a quarter of those terms were regular nouns and noun phrases. This suggests that these terms could be complimentary to more traditional methods of indexing using controlled vocabularies.

Abstract

The Underground Railroad was a network of people who helped fugitive slaves escape to the North and Canada during the U.S. Civil War period, beginning in about 1831. Quilting was used as a form of information representation (Breneman 2001). This simple classification was designed to relate the symbolic transmission of escape routes and locations of sanctuary. Because it was for use in a children's library, symbolic representations were used to anchor the classes. Symbols are based in the African graphic arts, the Adinkra symbols of Ghana (West African wisdom. 2001), and also from actual quilt practice (Threads of Freedom 2001 and Breneman 2001).
