Abstract

Over the past few years, collaborative social tagging and annotation systems that involve communities of users creating and sharing their own metadata, have exploded on the Internet. Examples of such systems include: Flickr, Del.icio.us, Connotea, YouTube, LastFm. Such systems are exemplary of the Web 2.0 phenomena because they use the Internet to harness collective intelligence. Although there are issues associated with the quality of the metadata generated, there are also significant advantages including the cost benefits of leveraging community effort and enhanced search and discovery services that result from richer, more relevant metadata and rankings of resources. In this paper we describe the HarvANA (Harvesting and Aggregating Networked Annotations) system that we are developing at the University of Queensland. The objective of HarvANA is to develop an efficient streamlined system (based on open standards and a set of open source services) that can leverage the explosion of community annotation/tagging systems and exploit the resulting metadata to improve discovery and reasoning across open repositories. Within the HarvANA system, community annotations are stored on (one or more) Annotea-compliant annotation servers that are separate from the collections that they are annotating. An OAI-PMH interface, built on top of the Annotation server(s), enables periodic harvesting of new annotations (since the last harvest). The harvested annotations are then aggregated with the institutional metadata (IM), to enrich the metadata store with community knowledge and enable more sophisticated and improved discovery services.
