Invisible institutional repositories: addressing the low indexing ratios of IRs in Google

Connotea Imports 2012-03-08

Summary:

From the abstract: "Google Scholar has difficulty indexing the contents of institutional repositories, and the authors hypothesize the reason is that most repositories use Dublin Core, which cannot express bibliographic citation information adequately for academic papers. Google Scholar makes specific recommendations for repositories, including the use of publishing industry metadata schemas over Dublin Core. This paper aims to test a theory that transforming metadata schemas in institutional repositories will lead to increased indexing by Google Scholar....The authors conducted two surveys of institutional and disciplinary repositories across the USA, using different methodologies. They also conducted three pilot projects that transformed the metadata of a subset of papers from USpace, the University of Utah's institutional repository, and examined the results of Google Scholar's explicit harvests....Repositories that use GS recommended metadata schemas and express them in HTML meta tags experienced significantly higher indexing ratios. The ease with which search engine crawlers can navigate a repository also seems to affect indexing ratio. The second and third metadata transformation pilot projects at Utah were successful, ultimately achieving an indexing ratio of greater than 90 percent...."
